Abstract:

AbstractDespite implant improvement and increasing standardisation of operation techniques, the rate of therapy failure of proximal humeral fracture care with primary osteosyntheses is estimated to be 10 to 20%. Most commonly failure is precipitated by: material failure, technical error, non-anatomical repositioning, avascular necrosis, lacking medial support. An additive medial stabilisation of the so-called “calcar region” can decrease failure rates significantly. An early correction osteosynthesis with the purpose of restoring the anatomy is indicated in bony, non-consolidated “fresh” fractures. Bony consolidated fractures should be classified according to Boileau and Walch. The authors of this article advice a structured and classification-adapted approach to treatment with a correction osteosynthesis. Post-traumatic deficits can be augmented utilising the following methods: correction osteosynthesis with allogeneic/autologous bone grafts, correction osteosynthesis with hydroxyapatite grafts. For the additive stabilisation of repositioned and fixated fractures, the following are described: correction osteosynthesis with an additive ventral one-third tubular plate, correction osteosynthesis with cement-augmented screws. Based on results of endoprosthetics following fractures of the proximal humerus, the correction osteosynthesis indeed represents a real therapeutic alternative in patients that are below the age of 60, a good bone mass and with relative functional requirements.

Abstract:

Data on the effectiveness of arthroscopic arthrolysis and extraction of osteosynthetic material after osteosynthesis of the proximal humerus in patients with persisting problems are rare and insufficient. In this study, we performed arthroscopic arthrolysis and extraction of fixation screws, and, where protruding, extraction of the nail in 34 patients with problems persisting 12 months after osteosynthesis of the proximal humerus using an intramedullary nail. The effectiveness of the treatment was assessed using the Constant–Murley shoulder score and forward flexion difference between the treated arm and the contralateral one. A median increase of 16 points in CMS score and 30 degrees reduction in the arm forward flexion difference was recorded 12 months after the arthroscopy. The improvement was significantly higher in the patient group with intramedullary nail extraction (however, this group had worse pre-operative values and the screw was only extracted where likely to cause problems). The median time to heal was 11 weeks; no serious peri- or post-procedural complications occurred. Mini-invasive arthroscopic arthrolysis combined with extraction of osteosynthetic material proved to be a safe and effective method for treatment of patients after osteosynthesis of the proximal humerus using an intramedullary nail with persisting pain and/or mobility limitation.

Abstract:

Bioabsorbable implants have become the focus of the latest research for new bone implant materials. With favorable characteristics such as compatible mechanical characteristics, no long-term side effects, and even osteogenesis enhancing properties they seem to be the future of osteosynthesis. Besides these characteristics, they must perform on the same level as traditional implant materials regarding their mechanical support for bone healing. A particular focus in the research for bioabsorbable implants has been on metal alloys, as these have particularly good mechanical properties such as excellent maximum force and high stability. This study focused on the shear strength of new bioabsorbable zinc and magnesium pins in comparison to traditional implants such as K-wires and cancellous bone screws in bone-implant connections. During quasi-static and fatigue loading experiments, magnesium pins (MAGNEZIX, Syntellix AG, Hannover, Germany) and new zinc silver pins (Zn-6Ag) by Limedion (Limedion GmbH., Mannheim, Germany) were compared with conventional osteosynthetic materials. The pins made of the new bioabsorbable alloys withstood the cyclic loads to the same extent as the conventional osteosynthesis materials. In the quasi-static loading, it was shown that the novel Zn-6Ag from Limedion has the same shear strength as the magnesium pin from Syntellix, which is already in clinical use. In addition, the zinc pin showed significantly better shear strength compared to osteosynthesis with K-wires (p < 0.05).

Abstract:

Three hundred thirty nine patients with femoral neck fractures were operated on during the period from 1990 to 1994. Most of operations were performed within 48-72 hours after trauma. 235 patients with an average age of 70 years were treated by osteosynthesis using plates, srews, rods, DHS. 104 patients with average age of 76 years underwent total hip replacement procedures using Moore, Baitmann, Muller, Spotorno (Etalon, Kiev) implants. 17 patients (5%) died. Out of them 10 patients died after total hip replacement, 4 patients - after closed osteosynthesis and 3 patients - after open osteosynthesis. In 96 patients with osteosynthesis results were evaluated after 1-2 years. Good results were in 78% of them, satisfactory - in 15,7% and bad - in 6,3%. Author supports as early as possible operative treatment of patients with femoral neck fracture and prefers an open osteosynthesis with spongy screws. Advantages of closed osteosynthesis with DHS is noted too.

Abstract:

Aim - to study the peculiarities of osteosynthesis in osteopenia with the application of the new metal fixator in post-mortem studies. Material and methods. New metal fixator for osteosynthesis in osteopenia has been developed. Measurements of the mechanical strength of osteosynthesis, and biomechanical tests of osteosynthesis stability with the application of this fixator were studied in 16 corpses (32 cases). Results. Biomechanical tests indicate that the new metal fixator is able to maintain the optimal position of anatomical reduction in 15 cases out of 16, while using a sponge screw AO type shows this result only in 6 cases out of 10. The mechanical strength of osteosynthesis with the use of the new metal fixator is 2,77 times greater than when using a sponge screw AO type. Conclusion. The carried out post-mortem examination testifies to the advantage of using the new metal fixator compared to the traditionally used sponge screw AO type for osteosynthesis in osteopenia.

Abstract:

Modern fracture surgery requires an increasing number of operative procedures utilising radiological control. During osteosyntheses patients receive scattered radiation when fluoroscopy is used. Unlike operating-room staff, patients are not protected during these procedures. The aim of this study was to measure the amount of scattered radiation in the phantom plane during a simulated osteosynthesis in order to evaluate the patient’s need for protection. A lower arm anthropomorphic phantom was irradiated with the use of a Philips BV Pulsera C-arm. The amounts of scattered radiation at distances from 10 to 160 cm and angles of 0 to 180 degrees in the phantom plane were measured with a real-time dosimeter. The same amount of measurements was repeated with a fixation plate on top of the phantom to simulate a fracture reduction operation. The maximum amount of scattered radiation was 1.63 µSv at a distance of 10 cm from the edge of the radiation beam. This phantom study shows that scattered radiation during osteosyntheses of the distal radius is negligible and therefore no patient protection is needed. The results should be interpreted carefully as this is a phantom study.

Abstract:

Results of the treatment of 218 victims with polytrauma were analyzed during the period from 1998 to 2202. There were 127 patients with one and 91 patients with several closed fractures. Authors consider osteosynthesis for closed long bone fractures to be an urgent operation of third term. Osteosynthesis is absolutely indicated to the patients with psychomotor excitation, in cases of the threat for skin perforation by bone fragments and in patients requiring intensive nursing for their life rescue. The choice of operative method depends on polytrauma severity and fracture type. When osteosynthesis is performed by urgent indications in patients with polytrauma the requirements to osteosynthesis stiffness are higher than in isolate injuries, as the rotation displacement, migration and fixator deformity frequently take place in unconscious patients who need constant intensive nursing. In patients with concomitant thorax injury urgent intramedullar osteosynthesis by nail is contraindicated due to the possibility of fat embolism syndrome development. In these patients plate osteosynthesis is preferred. If there are no absolute indications to urgent osteosynthesis this operation could be performed on 3-10 days after trauma using lightly traumatic and invasive methods not waiting for the complete normalization of homeostasis parameters and restoration of soft tissues in the fracture zone. In closed long bone fractures tactics of early osteosynthesis allows to decrease the rate of hypostatic complications and mortality by more than 10% and achieve good functional results.

Abstract:

Purpose: Displaced children’s forearms fractures are commonly treated surgically with Kirschner Wires or Elastic Stable Intramedullary Nails. The osteosynthesis system “Minimally Invasive Reduction and Osteosynthesis System” might be beneficial in the treatment of these fractures due to being minimally invasive while achieving fracture stability. In this exploratory prospective randomized controlled longitudinal study, we compared Minimally Invasive Reduction and Osteosynthesis System to Kirschner Wires and Elastic Stable Intramedullary Nails osteosynthesis. Methods: Twenty children were included consecutively to treatment with either conventional surgery (5 Kirschner Wires/5 Elastic Stable Intramedullary Nails) or Minimally Invasive Reduction and Osteosynthesis System (10). Evaluation of radiographic alignment and clinically of range of motion, pain status, grip strength, level of physical activity and scar size were compared after 3 months and after 5 years. Results: Surgical parameters of the duration of insertion- and removal-surgery, the need for postoperative casting and scar size were significantly better for Minimally Invasive Reduction and Osteosynthesis System. All osteosynthesis systems maintained radiographically fracture alignment at three months and 5 years follow-up. Clinical status regarding pain, grip strength difference, and return to recreational activities were not significantly different. The complication rates were nonsignificant, but MIROS had moderate severe complications of refractures, while mild complications occurred when operated on with Kirschner Wires/Elastic Stable Intramedullary Nails. Our study was sufficiently powered at 3 months, but the comparisons are suggestive at 5 years. Conclusion: In conclusion, Minimally Invasive Reduction and Osteosynthesis System is not significantly different to other surgical methods in radiological outcomes for forearm fractures in children. Minimally Invasive Reduction and Osteosynthesis System has the clinical benefit of omitting casting after surgery, obtaining reduced scar size, and shorter insertion and removal time without general anesthesia. However, moderately severe complications occurred. Level of evidence: Level II—a prospective comparative study

Abstract:

The experience treatment in 123 patients with un united diaphyseal fractures and pseudoarthroses of the crus (93 patients) and femur (30 patients) complicated by purulent infection is presented. Term after trauma ranged from 2 months to 12 years. Readmission treatment failed. Contractures, marked trophic disturbances, muscular at rophy were detected in almost all patients. Closed trans- osseous osteosynthesis using external fixation device was performed in 12 patients. One hundred eleven patients underwent one-stage operation including radical fistulosequester-necrectomy, when indicated or vast segmental sequestrnecrectomy and transosseous osteosynthesis by external fixation device with pins, rods or their combina tion. The pattern of osteosynthesis depended on the volume of bone defect formed after sequestrnectomy: monolacal osteosynthesis was used when the defect was up to 4 cm, bilocal osteosynthesis in 5-8 cm defect and polyfocal osteosynthesis when defect was over 8 cm. In one-stage treatment 96% of patients had positive out comes: elimination of osteomyelitis, bone healing and restoration of the extremity length. Treatment duration was 1.5-2 times shorter in comparison with routine treatment methods.

Abstract:

The treatment results of 31 patients with severe craniocerebral injury in combination with the extremity fractures (mainly femur and shin) are analysed. In 13 patients the osteosynthesis of long bones was performed within 3 days after injury and in 8 patients the fractures of the extremities were treated conservatively. Early 1-3 days osteosynthesis is shown to be performed on a more favorable metabolic level and contributes to the normalization of the disturbed correlation of the lipid peroxide oxidation and antioxidation system. Early stable osteosynthesis of the extremity fractures enables to improve the efficacy of the craniocerebral injury treatment and to prevent hypostatic complications, to shorten the terms of hospitalization (by 36% in comparison with later osteosynthesis) as well as the rehabilitation period. When no contraindications exit the osteosynthesis in this group of patients should be performed within 1 to 3 days after injury.

Abstract:

We suggest the following technique for intramedullary osteosynthesis of the shoulder. The patient lies on the healthy side. The injured limb is in the position of maximum extension. In closed osteosynthesis, the medullary canal is opened with a perforator from the puncture of the skin and soft tissues along the anterior edge of the acromial process of the scapula, where the upper pole of the head is projected. In open retrograde osteosynthesis a perforator is inserted into the same section. After osteosynthesis, the protruding end of the structure inserted under the acromial process of the scapula does not prevent restoration of function in the shoulder joint.

Conclusion: OSKE is an effective tool for the control of knowledge, including the methods of transosseous osteosynthesis. The inclusion of transosseous osteosynthesis station in the accreditation of orthopedic traumatologists is an urgent task.

Ligoniai ir metodai: Retrospektyviai išanalizuotos 237 pirminės šlaunikaulių osteosintezės Vilniaus universitetinės greitosios pagalbos ligoninės (VGPUL) Ortopedijos ir traumatologijos centre nuo 2003 iki 2010 metų. Į galutinę analizę įtrauktos 229 osteosintezės. Visi ligoniai pagal taikytą osteosintezės metodą suskirstyti į grupes: osteosintezė DCP plokštele, intramedulinė osteosintezė vinimi (IMV) ir išorinė fiksacija AO aparatu (IF). Ieškota reosteosintezės priežasčių: mechaninių komplikacijų, pseudoartrozės, supūliavimo. Rezultatai: Pagal AO (32) klasifikacija A tipo lūžis diagnozuotas 133 (56,1 %) pacientams, B tipo – 67 (28,3 %), C tipo – 37 (15,6 %). DCP grupėje iš 150 pacientų 29 (19,3 %) peroperuoti dėl mechaninių komplikacijų, 17 (11,3 %) – dėl pseudoartrozės ir 4 (2,6 %) – dėl supūliavimo. IMV grupėje iš 52 operuotųjų nė vienas neperoperuotas dėl mechaninių komplikacijų, 3 (5,8 %) peroperuoti dėl pseudoartrozės ir 1 (1,9 %) – dėl supūliavimo. IF grupėje iš 27 operuotųjų 7 (26 %) peroperuoti dėl mechaninių komplikacijų, 10 (27 %) – dėl pseudoartrozės ir 10 (27 %) – dėl supūliavimo. Išvados: Osteosintezė intrameduline vinimi yra pranašesnis metodas už osteosintezę plokštele, nes pastarojoje grupėje reosteosintezių dažnis buvo didesnis. Rekomenduojame, jei įmanoma, šlaunikaulio diafizės lūžius gydyti osteosinteze intrameduline vinimi. Reikšminiai žodžiai: reosteosintezė plokštele, intramedulinė fiksacija, šlaunikaulio osteosintezės plokštele komplikacijos, pseudoartrozės. The analysis of reosteosynthesis after diaphyseal femur fractures Andrius Vaitiekus, Mykolas Liubauskas, Igoris Šatkauskas Vilnius Universitety, Clinic of Reumatology, Traumatology-Orthopedics and Reconstructive Surgery, Orthopedics and Traumatolgy Centre, Vilnius University Emergency Hospital,Šiltnamių Str. 29, LT-04130 Vilnius, LithuaniaE-mail: andrius.vaitiekus@gmail.com Objective: To evaluate the rate of and reasons for reosteosynthesis after osteosynthesis of the middle third of the femoral diaphysis. Materials and Methods: Retrospectively, 237 medical histories of patients with diaphyseal femur fractures, who underwent primary femoral osteosynthesis in the Centre of Traumatology and Orthopaedics of the Vilnius University Emergency Hospital in 2003–2010 were analyzed; 229 osteosyntheses were enrolled into the final study. All patients, by the osteosynthesis method, were grouped into three groups: osteosynthesis with Dynamic Compression Plate (DCP), intramedullary nailing (IMN), and AO external fixation apparatus (EF). These groups were investigated for the reasons of reosteosynthesis (pseudarthrosis, mechanical complications, suppuration). Results: A fracture type (by AO classification) was diagnosed to 133 (56.1%), B type – 67 (28.3%), and C type to 37 patients (15.6%).In first group (DCP) there were 150 cases of osteosynthesis, from which 29 (19.3%) were reoperated on because of mechanical complications, 17 (11.3%) because of pseudarthrosis, and 4 (2.6%) because of suppuration. In the second group, there were 52 IM nailing cases, from which none were reoperated because of mechanical complications, altthough 3 (5.8%) had to be reoperated because of pseudarthrosis and one (1.9%) because of suppuration. In the third group, there were 27 external fixations of which 7 (26%), 10 (27%) and 10 (27%) were reoperated on because of mechanical complications, pseudarthrosis and suppuration, respectively. Conclusions: Osteosynthesis with intramedullary nail is a superior method to internal fixation with DCP, because the rate of reosteosynthesis after intramedullary nailing was lower. We recommend, when possible, to perform osteosynthesis with intramedullary nail for the treatment of diaphyseal femur fractures. Keywords: DCP plating, femoral shaft intramedullary nailing, femur plating complications, pseudoarthrosis.

Abstract:

Objective. To study the characteristics and healing duration of the diaphyseal femoral fractures, depending on the technologies used for osteosynthesis and the time between trauma and osteosynthesis. Methods. The study was performed on bred dogs (n=24). In the operating theatre all animals were modeled the transverse fracture of the femoral diaphysis in the middle third using a chisel. The animals were divided into 4 groups (6 per group). Animals of group 1 (one hour after the fracture) underwent transosseousosteosynthesis with a pin-rod external fixation device (PREF). In group 2, PREF was performed on the fourth day after the injury. In group 3 (one hour after the injury) blockable intramedullary osteosynthesis (BIOS) was performed. In group 4, the similar BIOS was performed on the fourth day after the fracture. To assess the results of treatment, the clinical, radiological and laboratory research methods were used. The duration of post-operative observation of the animals was 100 days. Results. It has been found out that the dynamics of osteoreparative processes in the studied groups was similar and did not depend on the time between trauma and osteosynthesis. The median time for the femoral shaft fracture healing in animals of group 1 was 46 days (Q1-Q3: 38-57), in group 2 - 73 days (Q1-Q3: 71-78) (differences between groups are significant at p=0.004); in group 3 - 49 days (Q1-Q3: 44-60), in group 4 - 72 days (Q1-Q3: 70-93) (differences between groups are significant at p=0.008). It is shown that the reason for the increase in fixation terms in dogs with the delayed osteosynthesis is the long-term persistence of the acute phase reaction caused by trauma (using the growth of C-reactive protein as an example). Conclusion. The healing terms of a femoral shaft fracture with the use of PREF technology and BIOS technology are comparable, both in the conditions of urgent and delayed osteosynthesis. What this paper adds It has been determined the similarity of the osteoreparation dynamics in the healing of diaphyseal femoral fractures: under conditions of osteosynthesis with a pin-rod external fixation device (PREF) and blocked intramedullary osteosynthesis (BIOS). For the first time it has been shown that healing terms of a diaphyseal femoral fractures when osteosynthesis performed in 4 days after injury is 1.5 fold longer in comparison with the performance of osteosynthesis within 1 hour after the injury. For the first time it has been shown that in the case of delayed osteosynthesis, the effectiveness of PREF and BIOS is comparable in terms of the duration of the consolidation of the diaphyseal femoral fractures.
