Abstract:

Objective: The aim of this study was to investigate the biomechanics of the facial skeletal for understanding the buttress after fixation with standard and modified anatomical thin titanium mesh (ATTM) plates by finite element (FE) analysis. Methods: Standard ATTM (SATTM) plate designed as the “L”-shape anticipated to be fixed in the ZMC anterior maxilla and lateral buttress to increase the fixation screw anchoring strength and another modified ATTM (MATTM) plate with a protrusion in the medial side and a slot and barb design in the lateral side to enhance the zygomaticomaxillary/nasomaxillary buttresses and provide precise positioning to the ZMC segments were studied by the FE analysis under masticatory forces with 250[Formula: see text]N. Result: The FE simulation results indicated that the total displacement distribution of the maxillary for ZMC fracture fixation with MATTM plate was smaller than that of SATTM plate. Stress concentration was found at the frontal and alveolar processes of the maxillary bone for SATTM plate fixation. Local vector plots of the first principal stress near the frontal process of the maxillary and zygomaticofacial formen of the zygomatic indicated that the stress flow for MATTM plate fixation was relatively close to nasomaxillary buttress, and the zygomaticomaxillary buttress, respectively. Conclusions: This study concluded that “L”-shape ATTM plate designed with a protrusion in the medial side and a slot and barb design in the lateral side can enhance the zygomaticomaxillary/nasomaxillary buttresses under uniform occlusal condition.

Abstract:

Stable, anatomical fixation of acetabular fractures gives the best chance of successful outcome, while penetration of the acetabular articular surface with screws is associated with poor outcomes. Spring plates are an alternative to interfragmentary lag screws when penetration is a concern. A mechanical study comparing fracture stability and construct stiffness of three fixation methods for posterior wall acetabular fractures with transverse comminutions was performed. The three fixation methods tested were a posterior wall rim plate, a posterior wall buttress plate with separate lag screws and a posterior wall plate with two spring plates. Nine samples were tested, three for each fixation method. Two-dimensional motion analysis was used to measure fracture fragment displacement and construct stiffness. After two 6000 cycle-loading protocols, to a maximum 1.5 kN, the mean fracture displacement was 0.154 mm for the rim plate model, 0.326 mm for the buttress plate and 0.254 mm for the spring plate model. Mean maximum displacement was significantly less for the rim plate fixation than the buttress plate ( p = 0.015) and spring plate fixation ( p = 0.02). The rim plate was the stiffest construct 10,962 N/mm, followed by the spring plate model 5637 N/mm and the buttress plate model 4882 N/mm. Based on data obtained in this study, where possible a rim plate with interfragmentary lag screws should be used for isolated posterior wall fractures as this is the stiffest and most stable construct. When this method is not possible, spring plate fixation is a safe and a superior alternative to a posterior buttress plate method.

Abstract:

Background: Effective surgical management is crucial for optimal outcomes in posterior malleolar fractures. This study compares the efficacy of lag screw versus buttress plate fixation techniques in treating these fractures. Aim and Objective: To compare the efficacy of lag screw versus buttress plate fixation in treating these fractures. Methods and Methods: In this prospective randomized controlled trial, 40 patients with posterior malleolar fractures were assigned to either lag screw fixation (n=20) or buttress plate fixation (n=20). Clinical outcomes were assessed using the American Orthopaedic Foot and Ankle Society (AOFAS) scores, range of motion (ROM), and radiographic evaluations over a mean follow-up period of 38.2 months. Results: At 1 year, the AOFAS scores for the lag screw group averaged 94.1 ± 5.4, and for the buttress plate group, 93.8 ± 5.6. ROM improved to 60.3 ± 6.4 degrees in the lag screw group and 60.0 ± 6.6 degrees in the buttress plate group. Complete union was achieved in 19 patients in each group, with minor step-off discrepancies noted in one patient per group. Complication rates were low, with superficial infections occurring in 1 patient from the lag screw group and 2 from the buttress plate group. Conclusion: Lag screw and buttress plate fixations provide comparable and satisfactory outcomes for posterior malleolar fracture management. Both techniques are effective, allowing surgeons to choose based on specific fracture characteristics and personal expertise.

Abstract:

Objective: Treatment of Schatzker Type 6 fractures is to use a posteromedial buttress plate as part of a double-column fixation technique. Materials & Methods: The design of this study was a cross sectional study design and this study was conducted in DHQ Teaching Hospital Gujranwala. patients with posterior medial fracture of Schatzker type 6 and having associated damage of some soft tissue present within the joint underwent surgery at our institutional operation theatre. In this Study setting we included total 20 patients (14 male [70%] and 6 females [30%]) who came with Bicondylar fractures having Comminuted Posteromedial Fragments of tibia. Results: Of the Patients, 12 (60%) had excellent results, 5(25%) had good results , and 3 (15%) had fair results. In total, 17 patients (85%) achieved cheering results. Walking, Stability, and motion were good or excellent in all cases. Practical Implication: One of the main advantages of the posteromedial buttress plate fixation technique is that it provides support to the medial column of the tibia, which is an important weight-bearing structure in the lower extremity. By restoring the structural integrity of the medial column, the technique can help promote early weight-bearing and facilitate early rehabilitation. All displaced posteromedial tibial plateau fractures should be surgically stabilized and buttressed using plate to restore joint congruity and prevent late subluxation and early arthritis. The aim is to study the role of posteromedial plating in the management of complex tibial plateau fractures with a posteromedial fragment Conclusion: Use of a posteromedial buttress plate as part of a double-column fixation technique can be an effective approach for treating Schatzker Type 6 fractures.

Abstract:

Background: Internal fixation modalities of unstable (>50 percent articular involvement) middle phalangeal volar lip fracture-dislocations include interfragmentary screw and volar buttress plating. This study investigates the mechanical properties (yield strength, ultimate tensile strength, and stiffness) of interfragmentary screw (IS), simple buttress plating (BP) and buttress plating with subchondral screw (BP+S). Methods: Fifteen cadaveric digits (5 index, 5 middle, and 5 ring) were prepared by excising its skin envelope and flexor tendons while preserving the structures around the proximal interphalangeal joint. An oblique osteotomy involving 50 percent of the articular surface was performed, and this was fixed with based on its study group: interfragmentary screw (IS), simple buttress plating (BP) and buttress plating with subchondral screw (BP+S). These specimens were then loaded to failure. Results: Yield strength was as follows: BP+S (33.5±9.76 N), IS (13.6±5.46 N), and BP (8.1±3.84 N). Ultimate tensile strength was as follows: BP+S (49.1±21.4 N), IS (15.6±5.19 N), and BP (8.86±3.99 N). Stiffness was as follows: BP+S (4.77±1.32 N/mm), IS (2.44±0.86 N/mm), and BP (1.84±0.71 N/mm). Conclusions: A buttress plate and screw construct confers significantly more stability than either interfragmentary screw or buttress plate only fixation in an experimental model.

Abstract:

Acetabular fractures involving predominantly the anterior column associated with a disruption of the quadrilateral surface can be treated with instrumentation implementing the stabilization of the quadrilateral surface. The recently introduced suprapectineal quadrilateral buttress plate is specifically designed to prevent secondary medial subluxation of the femoral head, especially in elderly patients with reduced ability for partial weight bearing. Whereas there are guidelines available for safe screw fixation for the anterior and posterior columns, there might be a concern for intra-articular placement of screws placed through the infrapectineal part of the quadrilateral buttress plate. Within this report we analyzed retrospectively screw placement in 30 plates in postoperative CT scans using algorithms for metal artifact reduction. None of the screws of the buttress plate penetrated the hip joint. We describe the placement, length, and spatial orientation of the screws used for fracture fixation and suggest that the use of intraoperative image intensifiers with a combined inlet-obturator view of 30–45° best projects the screws and the hip joint. Preoperative knowledge of approximate screw placement and information for accurate intraoperative imaging may contribute to safe acetabular fracture fixation and may reduce operating time and limit radiation exposure to the patient and the personnel. This trial is registered with KEK-BE: 266/2014.

Abstract:

Background: Treatment of distal tibial metaphyseal fractures is often challenging and no single technique has been unanimously advocated. Open reduction and internal fixation with plates and screws allows better restoration of anatomical alignment but with more soft tissue complication. Simultaneous fixation of the fibula is not universally carried out. This study aims at evaluation of the outcome of plating technique and the effect of fixation of fibula fracture in treatment of distal tibial metaphyseal fractures. Material and methods: Thirty-one cases (14 cases in Group A with concomitant distal fibula fracture and 17 cases in Group B without distal fibula fracture) were analyzed retrospectively for the mean duration of full weight bearing, mean union time and complications, and compared. Results: The mean time for full weight bearing and radiological union in our study was 14.2 weeks (15.9 in Group A and 13.1 in Group B) and 23.8 weeks (26.6 in Group A and 21.5 in Group B) respectively. 16.1% of cases had post-operative complications including one case of deep infection and malalignment of 6 degree varus (following delayed union) was seen in one case of Group A. Range of motion (ROM) at ankle was not problem in any of the cases except the one delayed union which had 5 degrees of dorsiflexion and 15 degrees of plantiflexion. Conclusion: Open reduction and internal fixation with plate and screws in distal tibial metaphyseal fracture is more economic means of treatment modality with comparable incidence of post-union malalignment and union time,though more soft tissue complications compared to other modalities. Fixation of fibula fracture aids in reducing the incidence of malalignment.

Abstract:

Background: Recognition of fracture patterns and fixation of fracture to secure and maintain reduction is the key for successful management of more complex intra articular fractures of distal radius. Devices like buttress plates have been shown to provide excellent stability for an unstable fracture with either dorsal or volar metaphyseal comminution. The objective of the study was to evaluate the functional outcome of intra articular fracture of distal end of radius treated by open reduction and internal fixation by buttress plate using Criteria of Gartland and Werley Point System.Methods: Twenty patients with intra articular fracture of distal end radius were treated by open reduction and internal fixation by buttress plate in Al-Ameen medical college, Bijapur. Statistical analysis: The data obtained was represented as percentage.Results: The study included 20 patients, 11 males and 9 females aged from 21 to 69 years with mean of 40.2 years. The average duration of follow-up was 7 months ranged from 6-10 months. Using the Demerit scoring system of Gartland and Werley, we had 20% excellent results, 45% good results, 20% fair results and 15% poor result whereas, excellent to good results were found in 65% of patients. Conclusions: Open reduction and internal fixation by buttress plate provides better functional outcome in treating the intra articualar fracture of distal end radius. Excellent to good results are produced by using buttress plate for fixation of intra articular fractures of distal end radius. So, this procedure can be used as alternative to other procedures in treating intra articular fractures of distal end radius.

Abstract:

We retrospectively compared the results of volar plating and dynamic external fixation for acute unstable dorsal fracture-dislocations of the proximal interphalangeal joint with a depressed fragment. We treated 31 patients (31 fingers), 12 with volar buttress plating and 19 with dynamic external fixation. Follow-up averaged 35 and 40 months in the two groups, with a minimal 6-month follow-up. Average active flexion of the proximal interphalangeal joint was 95° after plate fixation and 87° after external fixation, with an active extension lag of –6° and –9°, respectively. Active flexion at the distal interphalangeal joint averaged 67° in the plate group and 58° in the external fixation group, with active extension lags of 0° and –5°, respectively. We conclude that both methods can obtain a good range of motion at the proximal interphalangeal joint. A limitation of the extension of the distal interphalangeal joint occurred with dynamic external fixation but not with volar buttress plating. Level of evidence: IV

Abstract:

Introduction: This following study examines distal radius fracture care, the most common upper extremity injury in the US. More than 300,000 fractures occur annually. Volar buttress plating is a popular method for treating unstable fractures due to its longevity and stability. Both Kirschner-wire and locking plates have pros and cons. The effects of the 2.7-mm volar locking plate have not been extensively studied despite multiple plating operations. Distal radial fracture treatment in the elderly is poorly researched. Aims and Objectives: This study aims to evaluate the functional results associated with buttress-plated distal radius fractures. Method: This prospective Study includes 65 patients aged 18–70 with buttress-plated distal radius fractures. The study used Gyaneswar et al.’s sample size (n = 4pq / d^2) to get 90% satisfactory-excellent results. Comorbidities, >3-week injuries, poor tissues, complicated fractures excluded. Frykman’s categorization used demographic, injury, and radiograph data from surveys. The orthopaedic surgeon uses traditional procedures and Lindstrom’s grading for post-op evaluation for ≥3 months. Result: A study used buttress plating to treat 65 distal radius fracture patients aged 18–70. The sample size of Gyaneswar et al.’s study was 90% to reach a satisfactory-excellent result. Comorbidities, injuries lasting more than three weeks, poor tissue quality, and severe fractures are eliminated. Post-operative grading was assessed by Lindstrom. Joint stiffness and infection were reported in Table 4. Conclusion: In conclusion, buttress plate fixation for distal radius fractures had a positive effect, consistent with other studies that were better constructed.

Abstract:

Objective: To demonstrate fixation options for comminuted fractures of the medial malleolus. Methods: We retrospectively analyzed patients operated on for ankle fractures who had comminuted fractures of the medial malleolus between 2014 and 2018. Five patients were included in the study, 3 women and 2 men aged 19 to 37 years. Four cases were fixed with a tension-band wiring technique using Kirschner wires and cerclage, and 1 case with lag screws and buttress plate. Results: Four cases progressed satisfactorily (AOFAS >70), and 1 case progressed to ankle arthrodesis. Conclusion: Fixation with a tension-band wiring technique using Kirschner wires and cerclage may be an alternative to osteosynthesis in comminuted fractures of the medial malleolus with small fragments. Fixation with lag screws and buttress plate may be used in cases with larger fragments. Level of Evidence IV; Therapeutic Studies; Cases Series.

Abstract:

Background: Bicondylar tibial plateau fractures (TPFs) present challenges in management due to articular surface involvement and soft-tissue complexities. The optimal fixation method for these fractures remains unclear. Objectives: This study aimed to compare the functional outcomes of bicondylar TPFs treated with unilateral periarticular locking plates, hybrid dual plates (locking plate and buttress plate), or classic dual buttress plates. Materials and Methods: A retrospective cohort study was conducted on 59 patients with bicondylar TPFs (Schatzker types V and VI) treated at three Level I trauma centers between 2008 and 2015. Functional outcomes were assessed using the Hospital for Special Surgery (HSS) Knee Score and the Oxford Knee Score. Results: Locking plate groups (unilateral and hybrid) demonstrated a higher percentage of excellent outcomes in HSS Knee Scores at 3 and 6 months postoperatively (p = 0.0291 and p = 0.0446, respectively) and Oxford Knee Scores at 6 months (p = 0.0253) compared to the classic dual buttress plate group. Unilateral plating showed a significantly higher percentage of excellent HSS scores at 6 months. Conclusions: The use of locking plates, either unilateral or hybrid, is associated with a higher likelihood of achieving excellent functional outcomes in bicondylar TPFs at 3 and 6 months postoperatively. Level of Evidence: Therapeutic Level III evidence, indicating a retrospective comparative study.

Abstract:

Background: Distal femoral fractures, often caused by high-energy incidents, present challenges due to comminution and subsequent complications. Non-union of the femur, resulting from factors like severe open fractures, infections, or implant failures, leads to functional limitations and reduced quality of life. Commonly, open reduction and internal fixation (ORIF) methods are employed, utilizing various devices such as locking plates, condylar screws, blade plates, and intramedullary nails. Deformities arising from distal femur fractures demand anatomical reconstruction. Aims and Objective: The study aims to evaluate the functional outcomes of comminuted distal femur fractures treated with lateral locking compression plate fixation and medial column augmentation using either the titanium elastic nailing system or a buttress plate. Materials and Methods: Twenty patients aged 18 and above with comminuted distal femur fractures were included. Preoperative assessment involved clinical examination and radiographs. Surgical procedures comprised lateral plate fixation and medial column augmentation with either the titanium elastic nailing system or a buttress plate. Follow-up evaluations occurred at 4, 12, and 24 weeks to assess knee range of motion and radiological union. Outcome assessment utilized the Lysholme knee scoring system. Results: Most patients achieved union in under 14 weeks, with an average union time of 15.15 weeks. Knee range of motion varied from <60° to >120°. Outcomes based on the Lysholme knee scoring system revealed 35% of patients achieving excellent results, 45% achieving good results, and limited complications—55% of patients had no complications, while 15% experienced knee stiffness. Conclusion: The study underscores the efficacy of lateral locking compression plate fixation combined with medial column augmentation in managing complex comminuted distal femur fractures. This approach provides reliable fixation and favorable functional outcomes. Lateral locking compression plate fixation with medial column augmentation proves effective in treating comminuted distal femur fractures, yielding stable fixation and promising functional results.

Abstract:

Introduction: Volar Barton’s fracture is a common problem among the distal radius fracture. Shearing fractures may involve the Volar articular margin is a displaced and inherently unstable fracture that may lead to pain, deformity, limited range of motion, and loss of hand function. In clinical practices, various methods are used for the management of Volar Barton’s fractures. The Volar buttress plate technique is now mostly chosen for the management of this type of fracture. The aim of the study was to observe the functional outcome of treating a Volar Barton’s fracture of the distal radius using a buttress plate. Methods: This prospective interventional study was carried out in the Department of Orthopaedic Surgery, BSMMU, Shahbag, Dhaka for the duration of 2 years 6 months (March 2014 to September 2016). Within this period 30 patients of Volar Barton’s fracture were selected as per inclusion and exclusion criteria who are admitted in this institution. After proper evaluation of these patients, open reduction and internal fixation were done with Volar locking buttress plate. Result: In this study, out of 30 patients 77% were male and 23%were female where the mean age was 32±9.3 and maximum incidence was between 18-39 years. Left side involvement was more 63% (19 patients) than right side involvement at 37% (11 patients). 7% of patients were found with superficial skin infections and treated non-operatively. In the final follow-up, 6.7% were obtained excellent scores, 73.3% were obtained good scores and 20% were obtained fair scores on the basis of anatomical outcome. Conclusion: The Volar buttress plate is found an effective technique of fixation. The Volar locking buttress plate maintained articular congruity, radial length, and alignment. The significant functional outcomes were observed at end of the final follow-up (24 weeks).

Abstract:

Radial head and neck fractures are common and at times require operative fixation. There is no consensus on the ideal fixation construct for unstable radial neck fractures. Using 7 fresh frozen cadaveric radii, fractures of the radial neck were created 2 cm from the articular surface. The fractures were stabilized with 5 different commonly used constructs: crossed K-wires; a 2.4-mm T-plate using screws in the head (T-plate and nonlocked screw construct); a T-plate using a screw and locked buttress pin in the head (T-plate and locked buttress pin construct); a T-plate with an interfragmentary screw from the shaft retrograde, through the plate into the head (retrograde interfragmentary screw construct); and a T-plate with an interfragmentary screw from a nonarticular portion of the head antegrade into the shaft (antegrade interfragmentary screw construct). All constructs were tested for bending and torsional rigidity using an Instron mechanical testing machine (Model 306; MTS Systems, Eden Prairie, Minnesota). The highest rigidity in both bending and torsion was the antegrade interfragmentary screw construct. During bending, the antegrade interfragmentary screw construct was significantly stronger than a T-plate and nonlocked screw construct. In torsion, the retrograde interfragmentary screw construct was significantly stiffer than K-wires and approached significance over a T-plate and locked buttress pin construct. Locking bolts vs screws into the head did not significantly increase rigidity in torsion or bending. In this model, plating showed an increase in stiffness in torsional loading as compared to K-wires. The addition of a lag screw across the neck fracture consistently showed an increase in torsional and bending stiffness of the constructs. These data may assist orthopedic surgeons in determining the best fixation for radial neck fractures.

Abstract:

Abstract Background Several types of fixation materials may be used for the radial styloid fractures such as Kirschner wire fixation, screw fixation, volar plate fixation, and fragment-specific radial buttress plate fixation. However, each of these fixation techniques has certain complications usually related to either the surgical dissection or the application of fixation and symptomatic permanent hardware. Implant removal secondary to irritation of prominent screw heads or bulky plates is not uncommon after radial styloid fracture fixation. Case Description Herein, two patients with an isolated radial styloid fracture who were treated with bioabsorbable magnesium (alloy: MgYREZr) screws are presented. In both patients, the fracture union was achieved without any complication and need for implant removal. Literature Review This is the first report on the use of magnesium screws for this indication. Clinical Relevance Magnesium bioabsorbable compression screw fixation may be an alternative solution that eliminates removal operations due to symptomatic hardware in radial styloid fractures.

Abstract:

Abstract Purpose The purpose of this study was to investigate and compare the clinical and radiological results of ORIF with inter-fragment screw or buttress plate fixation of acute PIP joint fracture dorsal dislocation. Patients and Methods Between January 2007 to December 2016, nineteen patients – 14 men and 5 women with an average age of 40.9 (19 to 64) years – were included in this study; 9 patients underwent small sized interfragmentary screw fixation and 10 patients underwent small buttress plating. The average follow-up period was 45.1 (13 to 78) months. Clinical assessment included measurement of range of motion (ROM) of the proximal and distal interphalangeal joint (PIP, DIP), grip and pinch strength, and pain with use of the Visual Analog Scale (VAS). At the postoperative X-ray, articular step off, gap, and degree of dorsal subluxation was measured, and maintenance of the reduction, fracture union, and the presence of degenerative changes were assessed. Results All patients achieved solid unions without instability. The overall average range of motion of PIP joint were from 9° to 85° (10–83° in the screw group, 8–87° in the plate group without significant difference). However, the screw group (average: 53°) presented more flexion in the distal interphalangeal joint than the plate group (average: 34°). Plate fixation can cause limited DIP flexion. Six of the ten patients from the plate group, underwent implant removal and two of these patients required PIP joint arthrolysis due to the PIP flexion contracture of more than 30°. Three of the nine patients in screw group underwent implant removal and two of the three patients required PIP joint arthrolysis. Conclusion Mini plate and screw fixation of acute PIP joint fracture dorsal dislocation can achieve comparable favorable clinical and radiographic outcomes through stable fixation and early range of motion exercise. Screw fixation, if possible, is probably preferable to plate fixation because of better DIP joint ROM and lower incidence of hardware removal. If there is a need for plate fixation the use of a short plate is recommended to avoid joint stiffness.

Abstract:

Purpose of the study — to provide an anatomical rationale and evaluate the clinical application of posterolateral surgical approach with osteotomy of the fibular head for internal fixation of the posterior aspect of the lateral tibial condyle. Material and Methods. Anatomical topography research was performed on 14 lower limbs of 8 fresh cadavers. In the first series of research L-shaped plate was fixed on the posterolateral surface of lateral tibial condyle from the examined approach, then preparation was performed and measuring of distances from various parts of the plates to the common peroneal nerve and anterior tibial artery. In the second series the authors prepared histological topograms by transverse sectioning of plastinated specimens from the knee joint area after implantation of L-shaped buttress plates. Prospective observation clinical study included 20 patients who underwent internal fixation with L-shaped buttress plate from the examined approach for fracture of the posterolateral column of the tibial plateau, type 41В by AO classification. KSS and Lysholm scales were used to evaluate treatment outcomes at days 7–10 and in 1, 3, 6 and 9 months postoperatively. Data of the anatomical and clinical research was compared. Results. Compliance with the technique of posterolateral transfibular surgical approach allows to avoid risk of injury to the common peroneal nerve and anterior tibial arthery which on the specimen were always located safely away from implanted plates. All 20 clinical cases demonstrated good visualization of bone fragments and articular surface of the tibial plateau which ensured reliable reduction and fixation by L-shaped buttress plate. KSS excellent and good outcome scores amounted to 50% and 45%, respectively, while satisfactory score was reported in 5% of cases; Lysholm scale demonstrated 55% of excellent outcomes, 45% of good outcomes, and 5% of satisfactory outcomes. Safety of the approach was verified: no injuries to large blood vessels or iatrogenic neuropathies were reported as well as no large hematomas or infectious complications of the surgical wound in early postoperative period. Conclusion. Results of the present study proved the feasibility and safety of the posterolateral transfibular surgical approach for internal fixation procedures in patients with intraarticular fractures of posterolateral column of the tibial plateau.

Abstract:

This study aims to evaluate the surgery outcomes of distal radius fractures using open reduction and internal fixation (ORIF) with buttress plate in our hospital. 200 patients were included with age above 18 years, having distal radius fractures and who were treated by ORIF buttress plate. The patients who had intraarticular distal radius fractures were included in this study. Data was collected from hospital records. Mean age of our patients was 38.5 ± 8.3 years. Patients were assessed functionally using Gartland and Werley point system and anatomically (radiologically) using Sarmiento’s modification of Lindstrom criteria. Among study participants, 140 patients had excellent restoration (70%), 20 patients had good restoration (10%) and the rest had fair restoration. There were some complications among patients like superficial infection and injury to superficial branch of radial nerve. In the follow up, we notice stiffness in one case with reduced range of movement of wrist and fingers. In our study, we had good to excellent results in 80% cases, anatomically and functionally. We conclude from our study ORIF using buttress plate is the best method for managing displaced intra-articular distal radius fractures.

Background: Distal femur AO type 33 B fractures are partial articular fractures. It also includes Hoffa’s fracture which is a relatively rare injury and requires always operative management even with no displacement. Approach to these fracture depend on the condyle involved also various quadriceps sparing approach like swashbuckler approach has been described in the literature. Surgical treatment of these fractures involves anatomical reduction, compression, stable fixation and early mobilization. Treatment modalities such as cancellous screws, pre-contoured anatomical locked plate, posterior condylar buttress plating, distal retrograde interlocking nailing, angled blade plate fixation, dynamic condylar screw may be considered. Each implant is associated with advantages and disadvantages which is discussed here.

Abstract:

Introduction: To improve hemostasis and visibility, a tourniquet was used throughout the majority of hand and wrist procedures, despite the fact that patient experience unnecessary and excruciating pain from the tourniquet. The more current method known as wide-awake local anesthesia without tourniquet (WALANT) enables intraoperative function evaluation while the patient is completely conscious. Materials and Methods: Individuals with displaced distal radius fractures that required surgery and isolated, non-concomitant injuries requiring spinal or general anesthesia were considered for WALANT technique. In our study, five patients underwent dorsal plate fixation and 20 patients underwent volar plate fixation. Patients receiving dorsal plate fixation required definite dorsal buttress to prevent radiocarpal dislocation. Conclusion: The WALANT technique is a simple, reliable, and effective anesthetic method for internal fixation and open reduction of distal radius fractures. Since a tourniquet is not necessary, the patient is protected from the discomfort and risks associated with one. Keywords: WALANT technique, distal end radius fracture, tourniquet, volar plating, dorsal plating.

Abstract:

Category: Ankle, Trauma Introduction/Purpose: The association between tibial shaft fractures and concomitant posterior malleolus fractures has been well-studied; however less is known about tibial shaft fractures and concomitant medial malleolus fractures. Treatment of tibial shaft fractures with a plate or intramedullary nail in the setting of concomitant medial malleolus fracture may pose obstacles to standard medial malleolus fractures fixation due to hardware that impedes optimal screw placement. The purpose of this study is to report the presentation and management strategies used to treat medial malleolus fractures in the setting of concomitant tibial shaft fractures. Methods: From 2011 to 2015, seven (1.4%) patients were identified with concomitant tibial shaft fractures and isolated medial malleolus fractures. Data was collected through review of patient charts, radiographs, and operative reports including the following variables: demographics, injury patterns, fixation techniques, and outcomes. Five male patients and two female patients with a mean age of 39.1 years (range, 13.9-67.9 years) were included. Three patients reported tobacco use. Mechanisms of injury included motor vehicle accident (n=4), fall from standing (n=2), and pedestrian versus vehicle (n=1). Average medial malleolus fracture fragment length was 19.1 mm (range, 14.3-29.4 mm). Tibial shaft fractures were open in four cases, and included five transverse patterns, one spiral pattern, and one segmental fracture. All patients were treated surgically for tibial shaft and medial malleolus fractures simultaneously. All medial malleolus reductions were anatomic. The average time to union for medial malleolus fractures was 3.12 months (range 1.53 to 5.93 months). Results: Fixation techniques included screw (n=5) or buttress plate (n=2) fixation for the medial malleolus, and intramedullary nailing (6) or blade plate fixation (n=1, prior TKA) for the tibial shaft. Of the five medial malleolus fractures treated with screw fixation, screws were positioned anteriorly (n=2) or medially (n=2) to tibial shaft fixation implant in four cases; in one case the distal extent of the tibial nail was proximal to the medial malleolar screws. One buttress plate was placed with screws distal to the tibial nail, another was placed angling one proximal screw anterior and one posterior to the tibial nail. Two patients reported complications following surgery: one with chronic pain and one with wound dehiscence and delayed union at the open tibial shaft fracture site. Conclusion: Seven patients were treated operatively for concomitant tibial shaft and medial malleolus fractures, requiring careful attention to placement of medial malleolar screws or buttress plate due to the presence of implant used to treat the tibial shaft fracture. Medial malleolar screws can safely be redirected anteriorly or medially to accommodate the tibial shaft fracture implant, with acceptable fracture union outcomes in this small case series. Further biomechanical and long-term data may help to validate these adjustments to standard techniques.

Abstract:

BACKGROUND: Indirect reduction technique offers a valid option in the treatment of proximal humerus fracture. The purpose of this study is to evaluate the functional outcome and the complication rate after indirect reduction and internal fixation of unstable proximal humeral fractures with use of a locking plate.METHODS: Twenty four patients with acute proximal humerus fracture were managed with indirect reduction and internal fixation with a locking plate. The mean follow-up period was 15.5 months.RESULTS: The anatomical reduction of the medial cortex buttress was seen in 16 patients (66%) of the Group A and the non-anatomical reduction was seen in 8 patients (33%) of the Group B. Mean union time was 3.2 +/- 1.9 months; it was 2.2 +/- 0.6 months in the Group A and 5.3 +/- 2.2 months in the Group B (p < 0.05). In our series, there were 6 cases of complications and these include 2 cases of varus malunion, 2 cases of shoulder stiffness, 1 case of heterotrophic ossification, 2 cases of screw perforation and 1 case of impingement.CONCLUSIONS: We conclude from our studies that indirect reduction and internal fixation using locking plate for acute proximal humerus fracture can give good results with bony union and predictable good overall functional outcome. If the medial cortex buttress is well maintained, a better anatomical reduction would be achieved, the union would be prompted, the pain would be further reduced and the range of the motion would be recovered more promptly.

Abstract:

We describe a technique of fixation for treatment of distal tibia periplafond fractures and nonunions that uses a modification of the principle of the fibula-pro-tibia procedure (fusing the tibia and fibula together to create a one-bone lower leg). The fibula is plated, and the screws are brought across to the medial tibial cortex. The procedure is accomplished with or without a tibial buttress plate and always includes iliac crest bone grafting of the nonunion site and synostosis. We have used this technique in five patients with satisfaction.

Abstract:

Treating scaphoid nonunions presents difficulties particularly when there is bone loss, significant humpback deformity or avascular necrosis. We describe a new type of fixation with a volar scaphoid plate that adds to the methods of internal fixation that are available for the treatment of recalcitrant scaphoid nonunions. We will also discuss ‘lessons learned’ from a cases series. The case series includes 20 consecutive patients treated with volar buttress plating and a pedicled vascularized bone graft from the ipsilateral volar distal radius. There was clinical and radiographic evidence of union in 18 of 20 patients, 13 of which were verified by computed tomographic scan. The range of motion was improved in all patients post-operatively. Four patients with radiographic union experienced intermittent clicking with maximal wrist flexion, believed to be due to the impingement of the plate on the volar aspect of the radioscaphoid articulation and underwent removal at approximately 1 year after the index procedure. Volar scaphoid plating is a useful alternative to headless scaphoid screw fixation in the treatment of unstable scaphoid waist fractures and nonunions. Level of evidence: IV

Abstract:

Introduction:Bicondylar Hoffa fractures are extremely uncommon injuries and there have only been a very small number of cases documented in the literature. Case Report:A 28-year-old male presented to emergency department with injury to right knee and leg. X-ray was taken; however, they were not sufficient to determine the precise fracture pattern, so computed tomography scan was done for establishing diagnosis. Fracture managed successfully using compression screws and buttress plate with satisfactory result after a follow-up period of 1 year with ROM 20–120° with no signs of Avascular necrosis or arthritis and we also discussed the appropriate treatment options with supporting literatures. Conclusion: We conclude by describing a rare case of Bicondylar Hoffa fracture managed by open reduction and internal fixation with cancellous screws and Buttress plating. All cases of unicondylar Hoffa must be evaluated with a high index of suspicion to not miss the cases of Bicondylar Hoffa, which is extremely uncommon injury.

Abstract:

SummaryA ten-month-old neutered Siberian Husky dog sustained a long oblique diaphyseal right femoral fracture which extended into and was secondary to a large metaphyseal bone cyst. The cyst was curetted and bone grafted. To attain adequate fracture and cyst stabilization, an AO/ASIF left tibial head buttress plate was used. Due to the unique configuration and curvature of the plate, three of 11 screws were placed in unaffected epiphyseal bone. This contributed to good frictional apposition of the plate to the bone with resultant excellent fracture stability. Twenty-six weeks after the operation the fracture and cyst had healed and the dog had full function of the limb. The lateral tibial head buttress plate should be considered for use in supracondylar femoral fractures, in large dogs, because of ease of application, good conformity to the distal curvature of the femur, plate stiffness and the resultant stability.A human tibial plate was used to stabilize a difficult femoral fracture which occurred secondary to a bone cyst. The unique dimensions and shape of the plate facilitated excellent conformity of the plate to the bone and enabled adequate screw fixation in the epiphysis distal to the grafted metaphyseal cyst defect. The fracture and cyst were healed at 26 weeks with excellent limb function.

Abstract:

Category: Ankle Introduction/Purpose: The purpose of current study was to retrospectively analyze the clinical outcomes of buttress plate treatment of posterior pilon fractures. Methods: Between January 2005 and December 2016, 58 patients with posterior pilon fractures underwent buttress plate fixation. There were 32 males and 26 females and the mean age was 40.2years (range, 23 to 73 years). Preoperative radiographs, CT scans and three dimensional reconstructions were used to evaluate the fracture patterns. On the basis of the extension of the fracture lines presented on the CT scans, a posterolateral approach or a combination of both posterolateral and posteromedial approaches were used to reduce and fixate the posterior malleolar fragments. Clinical and radiographic examinations were used for postoperative follow-up. The American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score and the Visual Analogue Scale (VAS) were used to evaluate the functional outcomes. Results: According to the CT scan images, the posterior pilon fractures were classified into 3 types. 51 patients were available for follow-up. The mean time of follow-up was 44.8 months. The mean AOFAS score was 84.3 points, and the mean VAS score was 1.6 points. One patient was found with ankle joint swelling and long term walking discomfort at 2-year follow-up. Other patients received favorable functional outcomes. No hardware failure occurred. Conclusion: The clinical outcomes of buttress plate treatment of posterior pilon fractures were satisfactory. Buttress plating availed the patients to return to earlier weight-bearing and functional exercises.

Abstract:

Background: Present study looked at functional outcomes and rate of complications in cases of adult supracondylar-intercondylar femur fractures treated with different treatment modalities at a tertiary care government hospital.Methods: The study was conducted over 2 years wherein 23 patients with fracture in intercondylar-supracondylar region were included. The different implants and surgical techniques used in the study were: Condylar blade plate, dynamic condylar screw (DCS) with side plate, buttress plate single, supracondylar nail technique and TARPO technique. Neer’s criteria was used to compare functional outcome with different modalities of treatment.Results: Eight out of 11 patients treated using DCS with side plate-showed excellent results as per Neer’s criteria. Excellent results were observed in 3 out of 4 fractures fixed with GSH supra-condylar nail, 3 out of 3 in those fixed with TARPO technique, 0 out of 3 in patients managed using buttress plate and 1 out of 2 patients treated with blade plate.Conclusions: Closed method of reduction followed by internal fixation (TARPO technique and GSH nail) is better than open reduction (Buttress plate, DCS with side plate and condylar blade plate) for the management of fracture supracondylar femur. DCS with side plate by open method is at par with GSH nail and TARPO technique for knee ROM and rate of complications. It is recommended that, the Neer’s criteria should not be utilised in isolation for the purpose of comparing outcomes in cases of fracture supracondylar femur.

Abstract:

Background: High Tibial Osteotomy (HTO) is an approved surgical technique for varus knee deformity. For open wedge HTO multiple fixation methods and devices have been used. Advantages and disadvantages of these methods and devices are reported in various studies. Few studies have been conducted on use and final outcome of correction of varus knee deformity by implementation of non locking plates and benefits of this method is not fully evaluated. Objectives: To assess clinical and radiographic features of non-locking 4.5 millimeter L-buttress plate and T-buttress plate, which is used in open wedge High Tibial Osteotomy (HTO), and to find out whether this device is efficient enough or not. Methods: This cross-sectional study was conducted on 39 patients with tibial deformity recruited from a referral orthopedic hospital in Iran. Patients’ information, including their baseline characteristics, Range of Motion (ROM) of the knee, comorbidities, time of weight-bearing, union time in x-ray, graft type, and time of follow-up were reported at two stages: before and after the operation. Radiographic images were taken from their legs in both stages. Although different surgeons operated on the cases, they all used the same method. After the surgery, they were checked up in 2, 6, 12, and 24 weeks and a second alignment view was taken from the patients. Results: Thirty-nine patients underwent surgery for the correction of genu varus deformity and the follow-up time was between 6-48 months. There was no case of non-union and the ROM was perfectly restored in all the patients. Conclusion: Although the rate of the success in the use of the locking plate in HTO is higher, the use of a 4.5-mm non-locking plate seems to have decent results, too; therefore, it could be used as an alternative yet functional fixation tool in HTO.

Abstract:

Category: Ankle Introduction/Purpose: The purpose of current study was to retrospectively analyze the clinical outcomes of buttress plate treatment of posterior pilon fractures Methods: Between January 2005 and December 2009, 16 patients with posterior pilon fractures underwent buttress plate fixation. There were 11 males and 5 females and the mean age was 37.6 years (range, 23 to 62 years). Preoperative radiographs, CT scans and three dimensional reconstructions were used to evaluate the fracture patterns. On the basis of the extension of the fracture lines presented on the CT scans, a posterolateral approach or a combination of both posterolateral and posteromedial approaches were used to reduce and fixate the posterior malleolar fragments. Clinical and radiographic examinations were used for postoperative follow-up. The American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score and the Visual Analogue Scale (VAS) were used to evaluate the functional outcomes. Results: According to the CT scan images, the posterior pilon fractures were classified into 3 types. 14 patients were available for follow-up. The mean time of follow-up was 37.6 months (range, 16 to 52 months). The mean AOFAS score was 86.4 points (range, 70 to 98 points), and the mean VAS score was 1.4 points (range, 0 to 3 points). One patient was found with ankle joint swelling and long term walking discomfort at 2-year follow-up. Other patients received favorable functional outcomes. No hardware failure occurred. Conclusion: The clinical outcomes of buttress plate treatment of posterior pilon fractures were satisfactory. Buttress plating availed the patients to return to earlier weight-bearing and functional exercises.
