Abstract:

SummaryIn a retrospective study of fractures of the proximal ulna in dogs, 22 cases were identified over a 12-year period. Follow-up data was available for 13 dogs. Fractures of the proximal ulna were often comminuted, and most commonly had an intra-articular component affecting the ulnaro-humeral joint. Common causes included: motor vehicle trauma and falls from a height. Blunt thoracic trauma and additional orthopaedic injuries were often seen with the more severe types of fractures.Healing of intra-articular proximal ulnar fractures usually occurred after anatomical reconstruction and rigid internal fixation. Secondary osteoarthritis was minimal. The pin and tension band technique gave satisfactory results for simple non-articular fractures of the olecranon, but for intra-articular fractures this fixation method was associated with a greater incidence of complications such as: implant breakage, delayed union and infection. Implant loosening or breakage and delayed union were not observed, when fracture fixation with bone plates placed on the caudal or lateral aspects of the ulna was performed. Localized infection associated with a bone plate was identified in one of 10 patients and plate removal was carried out after the fracture had healed.Fractures of the proximal ulna in 13 dogs were frequently intra-articular and comminuted. Most fractures stabilized with tension band fixation or a small bone plate on the caudal surface of the ulna healed with minimal secondary osteoarthritis. However, complications with tension band fixation were common.

Abstract:

SummaryA fracture of the proximal 1/3 of the ulna, with concurrent fractures of the proximal radial physis and the distal 1/3 of the diaphysis of the radius occurred in a three-month-old, male, neutered, Domestic Shorthaired cat. The ulnar fracture was stabilised with an intramedullary pin. The proximal radial physeal fracture was reduced and stabilised with two crossed Kirschner wires. The proximal radius was secured to the ulna with an additional Kirschner wire. The distal radial diaphyseal fracture was stabilised with a five-hole, 2.0 mm dynamic compression plate (DCP). Six weeks postoperatively the cat was using the limb comfortably and demonstrated a full range of motion of the elbow joint. There were radiographic signs of fracture union and the radioulnar pin had migrated. The Kirschner wires were removed. Follow-up at 18 months postoperatively revealed that the cat was using the limb normally without any lameness. A full, pain-free range of motion was present in the joints of the left thoracic limb.

Abstract:

SummaryA 5-month-old German shepherd dog with a combination of a proximal radial physeal fracture and a proximal ulnar diaphyseal comminuted fracture, with cranial displacement of their distal fragment, was presented. This fractures combination resembles type I Monteggia fracture. After surgical reduction of the fractures, three full-cerclage wires were used to stabilize the ulnar fracture, and two positional screws were placed across the radius and ulna immediately distally to the growth plate to hold these bones in apposition. Four weeks post-operatively, the screws were removed since sufficient callus had been formed and the dog was free of lameness. It seems that if the appropriate conditions for a type I Monteggia fracture develop in an immature dog, proximal radial physeal fracture instead of radial head luxation may accompany ulnar diaphyseal fracture.

Abstract:

Objective To evaluate the use of Ilizarov external mini-fixation in the treatment of Monteggia fractures (dislocation of the radial head with an associated fracture of the proximal ulna) in children. Methods Children with proximal ulnar fracture were included and underwent fracture reduction surgery with Ilizarov external mini-fixators, followed by immobilization of the supinated forearm with plaster. The reduction was evaluated intra-operatively using arthrography. Mackay criteria were used to evaluate clinical outcomes at follow-up. Results A total of 15 children were included in the study. Mackay efficacy was 100 %, indicating excellent outcomes using the Ilizarov external mini-fixator. Conclusion Use of the Ilizarov external mini–fixator is particularly suitable in the treatment of children with comminuted and compression fractures of proximal ulna. It is easy to operate, low invasive and is worthy of promotion.

Abstract:

AbstractIn this case report, we describe an alternative surgical procedure to treat proximal radius and ulnar nonunion in a toy breed dog. A 14-month-old, Maltese cross-breed dog was referred after previous treatment with external and internal fixation had failed, resulting in a nonunion of a fracture of the proximal radius and ulna with the proximal radius fragment too small and friable to be used for fixation. A craniomedial approach was made to debride the radius nonunion site and a second approach to the lateral aspect of the ulna was made. The fracture was realigned and a titanium locking plate was applied in bridging fashion, fixed to the proximal ulnar fragment with three locking screws in the most proximal plate holes, a fourth screw was inserted in the mid-shaft of the distal ulnar fragment and three locking screws were inserted in the distal most holes of the plate through the distal ulna to engage the distal radial fragment. A recombinant bone morphogenetic protein 2 graft was inserted into the radius and ulna fracture sites. The dog had a successful clinical and radiographic outcome with bridging of the defect 4 weeks postoperatively and complete callus formation 8 weeks postoperatively. Implants have undergone dynamization and then removal. Use of a locking plate as an internal fixator achieving fixation of the proximal ulna and distal radius can be considered an option for the treatment of proximal radioulnar nonunions with a small proximal radial fragment.

Abstract:

Background: Distal ulna fractures at the ulnar neck can be seen in association with distal radius fractures, and multiple techniques have been described to address the ulnar neck component of these injuries. We have found that treatment of ulnar neck fractures can be challenging in terms of anatomy and fracture fixation. We present a new percutaneous fixation technique for ulnar neck fractures commonly seen with distal radius fractures. Technique: Fixation of the ulnar neck fracture is performed after fixation of the distal radius fracture. Our technique uses anterograde intramedullary fixation to stabilize the fracture with a 1.6-mm (0.062 inch) Kirschner wire or a commercially available metacarpal fixation intramedullary nail. The fixation is introduced into the intramedullary space of the ulnar shaft 4 to 6 cm proximal to the fracture at a separate surgical site along the subcutaneous border of the ulna. The fixation is also supported with a sugar-tong splint for the first few weeks after surgery and requires removal of the ulnar implant approximately 10 weeks after implantation. Conclusion: Our technique utilizes a percutaneous approach with minimal fracture exposure. It provides a relatively simple and reproducible method to address ulnar neck fractures commonly seen in association with distal radial fractures.

Abstract:

Fractures of the proximal ulna range from simple olecranon fractures to complex Monteggia fractures or Monteggia-like lesions involving damage to stabilizing key structures of the elbow (i.e. coronoid process, radial head, collateral ligament complex). In complex fracture patterns a computerized tomography scan is essential to properly assess the injury severity. Exact preoperative planning for the surgical approach is vital to adequately address all fracture parts (base coronoid fragments first). The management of olecranon fractures primarily comprises tension-band wiring in simple fractures as a valid treatment option, but modern plate techniques, especially in comminuted or osteoporotic fracture types, can reduce implant failure and potential implant-related soft tissue irritation. For Monteggia injuries, the accurate anatomical restoration of ulnar alignment and dimensions is crucial to adjust the radiocapitellar joint. Caution is advised if the anteromedial facet (anatomical insertion of the medial collateral ligament) of the coronoid process is affected, to avoid posteromedial instability. Radial head reconstruction or replacement is essential in Monteggia-like lesions to restore normal elbow function. The postoperative rehabilitation programme should involve active elbow motion exercises without limitations as early as possible following surgery to avoid joint stiffness.

Abstract:

Excision of the radial head after fracture may be complicated by longitudinal radio-ulnar instability (Essex-Lopresti lesion) if the forearm interosseous ligament has also been torn. In such cases proximal migration of the radius occurs, and ulnar impaction at the wrist and radiocapitellar contact at the elbow may impair function. Although metal radial head arthroplasties are now used for irreparable radial head fractures, the long-term clinical outcome may still be unsatisfactory because of excessive radiocapitellar load causing pain. Interosseous ligament reconstruction might improve outcome by restoring normal load transfer from the radius to ulna, but the biomechanical effect of reconstruction has not been reported. This study evaluated forearm load transfer following interosseous ligament reconstruction with an Achilles tendon allograft in a cadaveric model with the radial head intact. Interosseous ligament reconstruction reduced proximal radius loading by transferring force to the proximal ulna, but force transfer by the reconstruction was only half that by the intact ligament.

Abstract:

Purpose: Although plate osteosynthesis is commonly used to treat proximal ulna fracture, its treatment method is controversial because of complications such as large incision, long operation time, and soft tissue injury. Therefore, intramedullary headless compression screw (HCS) and Steinmann pin are considered as alternative treatment options. In this study, we aim to compare bending strength of plate and cortical screws, HCS, and Steinmann pin for proximal ulnar shaft fracture with sawbone. Methods: Transverse type fractures were made intentionally at the distal 7 cm from the proximal end of ulna sawbones and fixated with plate, HCS, and Steinmann pin after reduction. Three-point bending tests were performed with total of 21 sawbones, seven pieces for each group. Results: Average ultimate bending strength for each group was as follows; 521.7N for plate fixation group, 706.4N for HCS fixation group, and 812.6N for Steinmann pin fixation group. Statistically significant results were observed among the three groups (p<0.01). When two groups were compared separately, Steinmann pin fixation and plate fixation (p<0.01), Steinmann pin and HCS fixation (p=0.047) showed statistical significance. There was a significant trend between HCS and plate fixation group (p=0.064).Conclusion: HCS and Steinmann pin fixation showed higher bending strength when compared to plate fixation for proximal ulnar shaft fracture in sawbone. Although further studies are needed, HCS and Steinmann pin fixation are promising fixation methods that may be used as an alternative to plate fixation.

Abstract:

Background: Venous thromboembolism (VTE) has been studied in lower extremity fractures but little is known of its relation with upper extremity (UE) fractures. As an often overlooked but serious complication, VTE may compromise patient outcomes. Methods: Using data on inpatients (aged ≥ 18 years) at a level-I trauma center and patients in the National Surgical Quality Improvement Program database who sustained UE fractures (clavicle, humerus, or radius/ulna) and VTE in the same hospitalization between 2007 and 2014, the authors analyzed data on demographic characteristics, fracture type, VTE location (pulmonary embolism, lower extremity, or UE), VTE onset, polytrauma, operative or nonoperative management, comorbidities, and mortality. Results: Of 1984 inpatients with UE fractures at 1 instution, 9 experienced VTE on admission, and 17 (15 received thromboprophylaxis) experienced VTE during hospitalization, for an overall VTE rate of 1.3%. VTE occurred most often in patients with fractures of the proximal humerus (3.0%) followed by the clavicle (2.0%), midshaft humerus (1.9%), distal radius/ulna (0.95%), and distal humerus/elbow (0.36%) (p = 0.0035). There were no significant trends in the incidence of PE (p = 0.33) over the study period, but there was a sharp rise since 2011. In the national database, 42 of 11570 (0.36%) patients with UE fracture had VTE, with incidence by fracture location ranging from 0.14% (radius/ulna) to 0.98% (proximal humerus) (p = 0.00001). Predictors were chronic steroid use (odds ratio [OR] = 6.22, p = .030), inpatient status (OR = 4.09, p = .002), and totally disabled functional status (OR = 3.31, p = .021). Conclusions: VTE incidence was highest following proximal humerus or clavicle fractures and are rarely associated with radius/ulna fractures. There may have been a rise in the incidence of PE since 2007, warranting further investigation.

Abstract:

Monteggia fractures are accepted as hard-to-recognize and easy-to-handle fractures. Adequate radiographic investigations and clinical examinations are necessities. This case holds unique features involving diagnosis and treatment. In this case, the radial head was dislocated laterally while both bones were fractured in the proximal diaphysis, being the first to be mentioned in the literature. Closed reduction of the ulna is the preferred method of handling and almost always results in reduction of the radial head. Literature obligates ulnar reduction as a preliminary to reduce and stabilize the radial head. Closed reduction reduced the ulna but the radial head was not reduced. Hence an intramedullary K-wire was used to reduce the radial head and a long arm cast was used to stabilize the reduction. The operation was successful and follow-up showed no complications.

Abstract:

SummaryFragmented coronoid process occurred in four dogs with humeroradial subluxation secondary to premature closure of the distal radial physis. The medial coronoid process was affected in three dogs but in the fourth dog a single osteochondral fragment was located between the medial and lateral coronoid processes. One dog was treated by medial arthrotomy and lengthening of the radius. In three dogs the fragment was removed via a lateral arthrotomy accomplished by proximal ulnar diaphyseal osteotomy and the ulna was shortened at the ulnar osteotomy site to provide congruity of the proximal radio-ulnar and humeroradial articulations. The longterm clinical results were encouraging. The role of mechanical loading on the coronoid process in the pathogenesis of these cases is discussed.Four mature dogs were found to have fragmented coronoid process and humeroradial subluxation secondary to premature closure of the distal radial physis.It is proposed that the humero-radial subluxation placed ab-normal mechanical stress on the coronoid process of the ulna and caused its fracture or fragmentation.

Abstract:

Background: Monteggia fracture dislocations are a rare but a complex injury. The fracture of the ulna associated with proximal radioulnar joint dissociation and radio capitellar dislocation. This injury comprises less than 1% of all pediatric forearm fractures and typically affects patients between 4 and 10 years of age. There are many options for treatment of these fractures. The present study was planned to assess the clinical outcome of patients treated with open reduction and internal fixation of ulna with plating.Methods: The study was conducted in department of orthopedics, government medical college and hospital, Jammu from August 2018 to January 2021. 25 patients of Monteggia fractures were managed with open reduction and internal fixation of ulna with plating. Patients were evaluated at follow-up for pain, stability and disturbance of daily and sports activities. Functional outcome was assessed using elbow performance score.Results: Mean age of study participants was 8.2 years and male children predominated our study constituting 17 patients (68%). 14 patients were Bado type 1, four patients were Bado type 2 whereas seven patients were Bado type 3. The outcome was excellent in 18 patients (72%) and no cases of failure were encountered.Conclusions: Stable anatomical fixation by open reduction and internal fixation of ulna fractures with plating, that in turns leads to the stable reduction of radial head, in the management of acute Monteggia fracture dislocations in children has a very good outcome.

Abstract:

BACKGROUND: Normal elbow joint kinematics has been widely studied in cadaver, whilst in vivo study, especially of the forearm, is rare. Our study analyses, in vivo, the kinematics of normal forearm and of malunited forearm using a three-dimensional computerized simulation system.METHODS: We examined 8 patients with malunited Monteggia fracture and 4 controls with normal elbow joint. The ulna and radius were reconstructed from CT data placing the forearm in three different positions; full pronation, neutral, and full supination using computer bone models. We analyzed the axis of rotation 3-dimentionally based on the axes during forearm rotation from full pronation to full supination.RESULTS: Axis of rotation of normal forearm was pitch line, with a mean range of 2 mm, from full pronation to full supination, connecting the radial head center proximally and ulnar fovea distally. In normal forearm, the mean range was 1.32 mm at the proximal radioulnar joint and 1.51 mm at the distal radioulnar joint. However in Monteggia fracture patients, this range changed to 7.65 mm at proximal and 4.99 mm at distal radoulnar joint.CONCLUSIONS: During forearm rotation, the axis of rotation was constant in normal elbow joint but unstable in malunited Monteggia fracture patients as seen with radial head instability. Therefore, consideration should be given not only to correcting deformity but also to restoring AOR by 3D kinematics analysis before surgical treatment of such fractures.

Anterior elbow dislocations in the pediatric population represent rare and sometimes difficult injuries to manage. Associated olecranon fractures are even more uncommon with limited literature existing on the topic. We present the case of a six-year-old male with a traumatic transolecranon anterior elbow fracture dislocation in whom closed reduction was prevented by buttonholing of the proximal ulna through the anterior joint capsule. This case of pediatric anterior elbow fracture dislocation provides insight into an uncommon and challenging injury complex.

Abstract:

Introduction. Limb salvage surgery following proximal ulna resection poses a challenge in reconstruction of the complex elbow anatomy. Various reconstruction methods described offer inadequate restoration of function and stability. Following resection of proximal ulna tumors, we aimed to restore the joint using the resected osteochondral segment of proximal ulna treated with extracorporeal irradiation and reimplantation. Questions/Purposes. (1) Does irradiated osteoarticular autograft reconstruction for proximal ulna allow anatomical joint restoration and what are the oncological and functional outcomes? (2) Is there evidence of graft-related complications or osteoarthritis at a minimum of 2 years follow-up with irradiated osteoarticular autografts for the proximal ulna? (3) How does our method of reconstruction fare as compared to reported reconstruction options in the literature? Materials and Methods. 3 patients with primary bone tumors involving the proximal ulna underwent limb salvage surgery with en bloc resection and reconstruction using the resected bone after treating it with extracorporeal irradiation of 50 Gy. Minimum follow-up of 2 years was considered for assessment of final outcomes. Radiographs were assessed for bony recurrence, union across osteotomy junction, and signs of joint arthritis. Functional outcome measures included range of movement, muscle power testing, and functional and disability scores. Results. 2 complete and 1 partial olecranon involving proximal ulnar resections were performed for three cases of Ewing’s sarcoma in 2 males and 1 female. Follow-up ranged from 28 to 42 months, and all patients continue to remain disease free. All 3 patients have achieved full range of flexion-extension and pronosupination movement in comparison to the contralateral side. Muscle power for flexion and extension was 5/5. MSTS score: 100% (30/30); MEPS score: 100; and DASH score: zero were achieved for all patients. Union across osteotomy junctions at median follow-up of 8 months without need for intervention/bone grafting was achieved. No complications related to joint laxity/subluxation, infection, graft fracture, or implant failure was noted. None of the patients have clinical or radiological signs of joint arthritis across the irradiated articulation. Conclusion. Biological restoration of elbow anatomy using osteoarticular irradiated graft for proximal ulna reconstruction offers great joint stability and functional outcomes. Although the potential risks of infection and graft failure need to be considered, reconstruction with the size-matched radiated autograft eliminates donor site morbidity, offers a low-cost alternative to endoprosthesis, and provides outcomes superior to any other methods of reconstruction as analyzed from the literature.

Abstract:

We report a case of a 69-year-old right-dominant man who had an open Monteggia-like lesion of the right elbow (Gustilo-Andersen IIIA) with severe proximal ulna bone loss associated with an ipsilateral ulnar shaft fracture due to a motorcycle accident. The patient underwent two-stage surgery. Wound debridement and bridging external fixation were performed at first. Three months later, a frozen massive osteochondral ulnar allograft was implanted and fixed with a locking compression plate. A superficial wound infection appeared 5 weeks after the second surgery. Superficial wound debridement, negative pressure therapy, and antibiotics were administered for 3 months, achieving infection healing. At 3 years post-surgery, the elbow range of motion was satisfactory with a Disabilities of the Arm, Shoulder and Hand (DASH) score of 16.7. Radiographs and computed tomography scans showed good allograft-bone integration without allograft reabsorption or hardware loosening. Although not complication-free, massive ulna osteochondral allograft implantation can be considered a valid option in cases of open Monteggia-like lesions associated with ulnar shaft fracture and severe bone loss in active patients, whenever osteosynthesis or joint replacement is not a proper solution. This type of bone stock restoration allows for future surgery, like arthroplasty, if needed.

Abstract:

A long ulna, as a result of congenital differential growth, such as Madelung’s disease, or injury, commonly a consequence of a malunited distal radial fracture, may present clinically as pain, decreased motion, mainly of pronosupination, and weakness of grip. Secondary effects may include perforations and tears of the triangular fibrocartilage complex, cartilage wear of the proximal surface of lunate and triquetrum and tears of the lunotriquetral ligament. Positive ulnar variance may be evident on X-rays but a prominent ulnar head cannot always be excluded when there is neutral ulnar variance and further investigations, such as an arthroCTscan or arthroscopy, may be necessary. The two principle treatment options are (a) resection of the distal ulna (Darrach’s and Sauvé –Kapandji’s techniques are commonly used) and (b) techniques preserving the ulnar head, including different modalities of shortening osteotomy. The aim is to regain a congruent distal radioulnar joint, restore painless and normal pronosupination and prevent onset of osteoarthritis of this joint.

Abstract:

Background Supracondylar fracture and forearm bone fracture in isolation is common musculoskeletal injury in pediatric age group But combined supracondylar fracture with ipsilateral forearm bone fracture, also known as floating elbow is not common injury. The incidence of this association varies between 3% and 13%. Since the injury is rare and only limited literatures are available, choosing best management options for floating elbow is challenging. Method In retrospective review of 759 consecutive supracondylar fracture managed in between July 2005 to June 2011, children with combined supracondylar fracture with forearm bone injuries were identified and their demographic profiles, mode of injury, fracture types, treatment procedures, outcome and complications were analyzed. Result Thirty one patients (mean age 8.91 yrs, range 2-14 yrs; male 26; left side 18) had combined supracondylar fracture and ipsilateral forearm bone injury including four open fractures. There were 20 (64.51%) Gartland type III (13 type IIIA and 7 type III B), seven (22.58 %) type II, three (9.67 %) type I and one (3.22 %) flexion type supracondylar fracture. Nine patients had distal radius fracture, six had distal third both bone fracture, three had distal ulna fracture, two had mid shaft both bone injury and one with segmental ulna with distal radius fracture. There were Monteggia fracture dislocation, proximal ulna fracture, olecranon process fracture, undisplaced radial head fracture of one each and two undisplaced coronoid process fracture. Type I supracondylar fracture with undisplaced forearm were treated with closed reduction and long arm back slab or long arm cast. Displaced forearm fracture required closed reduction and fixation with Kirschner wires or intramedullary nailing. Nineteen patients with Gartland type III fracture underwent operative intervention. Among them nine had closed reduction and K wire fixation for both supracondylar fracture and forearm bone injury. One patient with closed reduction and long arm cast application for both type III supracondylar fracture and distal third radius fracture developed impending compartment syndrome and required splitting of cast, remanipulation and Kirschner wire fixation. There were three radial nerve, one ulnar nerve and one median nerve injury and two postoperative ulnar nerve palsy. Three patients had pin tract related complications. Among type III, 16 (80%) patients had good to excellent, two had fair and one gad poor result in terms of Flynn’s criteria in three months follow up ConclusionDisplaced supracondylar fracture with ipsilateral displaced forearm bone injuries need early operative management in the form of closed reduction and percutaneous pinning which provides not only stable fixation but also allows close observation for early sign and symptom of development of any compartment syndrome.DOI: http://dx.doi.org/10.3126/kumj.v9i2.6280 Kathmandu Univ Med J 2011;9(2):11-16

Abstract:

“Floating elbow” injuries of the arm traditionally represent a combination of humeral shaft and forearm fractures which require anatomic rigid open reduction and internal fixation of all fractures to allow for early range of motion exercises of the elbow. There are published variants of the floating elbow injury which include ipsilateral diaphyseal humeral fracture, proximal ulna fracture with proximal radioulnar joint disruption, and ipsilateral diaphyseal humeral fracture with elbow dislocation and both bones forearm fracture. We present the case of a 21-year-old woman whose left arm became caught between the side of a waterslide and adjacent rocks at a park. She sustained a torsional and axial loading injury to her left upper extremity resulting in ipsilateral humeral shaft and Galeazzi fractures. The combination of ipsilateral humeral shaft and Galeazzi fractures resulted in a rare floating elbow variant. Prompt open reduction and internal fixation of both fractures and early range of motion of the elbow and wrist resulted in an excellent clinical and radiographic result. Floating elbow injuries and their variants should be promptly recognized as early anatomic reduction, and rigid internal fixation can allow for good elbow function with minimization of stiffness.

Abstract:

Introduction: Untreated ununited scaphoid fractures will almost inevitably progress to radiographic and symptomatic osteoarthritis of the wrist. This may lead to subsequent morbidity and lifelong disability especially in young males in which the fracture scaphoid is more common. Patients and methods: Twenty-one patients presenting non-united fracture scaphoid were operated upon by using disto-proximal bone peg technique with average time between injury and operation as 11 months (6–18 months). All of them male with average age of 26 years (17–35 years). There were 17 patients with fracture waist (80.9%) and four patients with fracture proximal pole (19.1%). Results: Anatomy of the wrist was restored and radiological healing confirmed in 17/21, partial healing in 3/21 and non-union in 3/21 patients. Eighteen patients (85.7%) were graded as satisfactory, 5 patients (23.8%) were graded as excellent, ten patients (47.6%) were graded as good, and three patients (14.3%) were graded as fair. The remaining three patients (14.3%) were graded as unsatisfactory. Conclusion: We conclude that the disto-proximal bone peg technique of taking the graft from the ipsilateral ulna without using any metal work for fixing scaphoid non-union fracture is a reliable, easy, and inexpensive alternative method. However, we would not recommend it for the non-union of the scaphoid proximal pole fracture. Also we find the time lag before operation is one of the most important factors to achieve union in non-united fractures of the scaphoid. Level of evidence: Therapeutic case series, level 1V.

Abstract:

Monteggia fracture dislocations can be classic or equivalents. Equivalents, also known as Monteggia like lesions, are very rare especially type III and IV, which have been added to the literature after Luis Bado presented the original classification system of Monteggia fracture dislocations. Type III equivalent is classically defined as a proximal ulna fracture associated with a fracture of the lateral condyle of the humerus. In the literature only seven such cases have been reported so far. Here we present two such cases where one eight-year-old boy had a complex type of injury with a shear type fracture of the lateral humeral condyle and other a seven-year-old boy who had a plastic deformity of the ulna with an avulsion type fracture of the lateral humeral condyle. We also try to describe a novel mechanism of injury, known as, “Barzulla circle”, for the classical as well as equivalent type III Monteggia fracture dislocations.

Full text

Abstract:

A finite-element analysis model of the lunate was established using geometrical data obtained from cadaveric bones. The lunate cortex was modelled with triangular and quadrilateral elements and its intraosseous structure was represented either as a homogenous elastic structure or as an anisotropic network of cortical bone beams (trabeculae) with different orientations and thicknesses. Compressive loads applied to the metacarpus were distributed in the carpus against the fixed radius and ulna. The ulnar variance had a strong influence on the ratios radiolunate/ulnolunate total load and peak pressures. The distribution of internal stresses was markedly affected by the lunate uncovering index. The evolution of a simulated incomplete fracture was dramatically influenced by morphological parameters: with positive ulnar variance, the fracture did not progress, but in the presence of three associated conditions, negative ulnar variance, a high lunate uncovering index and angulated trabeculae, the fracture progressed and the proximal part of the lunate collapsed. This study supports the concept that some lunates are predisposed to Kienböck’s disease because their anatomy induces abnormal internal stresses, which allow an incomplete fracture to progress, under heavy loading conditions, and cause progressive collapse and localised trabecular osteonecrosis.

Abstract:

We report a 45-year-old male archer with stress fracture in his left ulna on the background of adult type of hypophosphatasia. The patient presented to several medical centers for pain around the left elbow and received medical treatment upon diagnosis of tenosynovitis. History of the patient revealed that he had had diagnosis of hypophosphatasia ten years ago and underwent percutaneous screwing for stress fracture on both of his femoral necks. Upon finding nondisplaced stress fracture on proximal metaphysis of the ulna on X-ray, the patient underwent magnetic resonance imaging (MRI) in order to exclude pathological causes. No additional pathology was observed in MRI scanning. The patient’s sportive activities were restricted for 6 weeks and he received conservative management with arm slings. Adult type of hypophosphatasia is a disease manifesting with widespread osteoporosis and presenting with low serum level of alkali phosphatase (ALP). Stress fracture should definitely be considered in the patients with history of hypophosphatasia and refractory extremity pain.

Abstract:

Introduction. In 1814 Giovanni Monteggia first described two cases of fractures of the proximal third of ulna with dislocation of the radial head. These fractures are more common in children than in adults, and mutual Monteggia fracture is a rare complication. This study presents a treatment course of a patient with bilateral Monteggia fracture. Case report. A 55- year-old patient was injured by falling in the yard. Radiography showed bilateral Monteggia fracture type II (by the Badon classification). Operative treatment of fracture was done by a compression plate on the right side and by the zuggurtung technique on the left one. Closed repositioning of the radial head was done on both sides. The patient was wearing a plaster splint for the upper arm for 21 days. After removing the fixation, the function of the elbow was determined by the Broberg Morrey score (BM) which was on the right side 45.5 and on the left side 47.5. After the proper physical therapy, four months after the surgery, BM score was 100 on the right side, and 93 on the left one. Conclusion. Surgical treatment and early rehabilitation is the key for the return of good function of both elbows.

Abstract:

A 25-year-old woman presented to the emergency room with a painful and swollen right forearm. She had just sustained an injury from an accident during which her arm was tightly wound by a rope as she was lowering a net from a fishing boat. Before being released, her arm was rigidly trapped in the rope for approximately ten minutes. Radiographs revealed anterior dislocation of the radial head that was accompanied by plastic deformation of the proximal ulna, manifested as a reversal of the proximal dorsal angulation of the ulna (PUDA); suggested a Monteggia equivalent fracture. With the patient under general anesthesia, we reduced the radial head by posterior compression at 90° of elbow flexion and at neutral rotation of the forearm. However, the reduction was easily lost and the elbow re-dislocated with even slight supination or extension of the arm. After the osteotomy of the ulnar deformity to restore the PUDA to normal, the reduction remained stable even with manipulation of the arm. We found that the patient could exercise a full range of motion without pain at the 3-month follow-up, and neither residual instability nor degenerative changes were observed at the final 3-year follow-up.

Abstract:

SummaryA Squirrel Monkey (Saimiri boliviensis) presented with comminuted, proximal diaphyseal fractures of the left radius and ulna which were repaired with a type II acrylic external fixateur and intramedullary pin, respectively. The external fixateur was removed six weeks postoperatively as the antebrachium was stable despite radiographic evidence that the radial fracture had failed to completely heal. Eight months postoperatively, radiographic examination revealed a nonunion fracture of the proximal radial diaphysis. The nonunion fracture was stabilised with a miniplate and screws, and osteogenic protein-1 (OP-1) (bone morphogenetic protein-7) was inserted to augment bony union. Radiographic evidence of fracture healing was present four weeks postoperatively. Bone morphogenetic proteins, in particular OP-1, can be used as a substitute for autogenous cancellous bone if there is an insufficient quantity of cancellous bone or harvesting will result in unacceptable morbidity.Osteogenic protein-1 (OP-1 or bone morphogenetic protein 7) was used in the management of a nonunion fracture of the radius in a Squirrel Monkey (Saimiri boliviensis). Osteogenic protein-1 was used in preference to autogenous cancellous bone as the small size of the monkey would have limited the quantity of cancellous bone and predisposed to morbidity at the harvest site. This is the first report of the clinical use of OP-1 in veterinary surgery.

The fracture was first stabilized with bone plates at LVH but non-union was observed. Resorption of bone was visible radiographically around the proximal screw, which led to fracture and implant loosening at that location. Pan-arthrodesis followed after stem cells administration was performed at FVH. Radiography showed sufficient growth of the radius and union of the ulna occurred at 145 days after therapy. The third case was a 3.5-year old, 10[Formula: see text]kgs intact male Mongrel attended at LVH for a humerus fracture. Fracture reduction with bone plates was attempted twice at LVH but both loosened eventually. At FVH, an external skeletal fixator was used to stabilize the fracture, followed by stem cell therapy. There was radiographic evidence that the humerus healed well by the 35th day after therapy and was completely united by Day 113 of post-surgery and therapy.

Abstract Objectives The aim of this study was to describe a case of an intra-articular olecranon fracture in a lamb repaired using a String of Pearls locking plate system, intramedullary pin and lag screws. Materials and Methods A 6-month-old, 20 kg, purebred male Merino lamb was referred for evaluation of a non-weight bearing lameness of the left thoracic limb of unknown duration. Orthogonal radiographic assessment of the left elbow revealed a complete, closed, long sagittal oblique, minimally displaced fracture of the olecranon involving the ulnar shaft at the level of the radial physis, extending proximally through the distal semilunar notch to the mid-body of the olecranon. The fracture was repaired using a String of Pearls locking plate system spanning both the proximal radius and olecranon, an intramedullary pin in the ulna and lag screws across the fracture line. Results Orthogonal radiographic assessment of the left elbow at 8 weeks postoperatively revealed implant quiescence with radiographic union of the fracture site. Long-term telephone follow-up at 3 and 6 months postoperatively found the patient was no longer restricted in activity, with free access to the field, and was not displaying an overt lameness. Clinical Significance The authors describe a novel method to treat an intra-articular in a lamb olecranon fracture in a lamb using a String of Pearls locking plate system, intramedullary pin and lag screws.

Abstract:

Schwannoma or neurilemmoma is a common soft tissue neoplasm arising from the neural sheath of Schwann cells. However, intraosseous schwannoma is rare, accounting for less than 0.2% of primary bone tumours. Several variants of schwannoma have been reported; among them, intraosseous schwannoma with ancient change is extremely rare. This current report presents an extremely rare case of ancient intraosseous neurilemmoma. The patient presented with right elbow pain and disability. A radiolucent, well-defined, lobulated lesion with a thin sclerotic rim in the proximal ulnar metaphysis that had caused a pathological fracture was noted. The mass was surgically excised using marginal resection and bone curettage was undertaken. The bone deficit was grafted with hydroxyapatite and β-tricalcium phosphate and augmented with bone cement. There were no signs of any recurrence after 3 years. This is the first case of an ancient intraosseous schwannoma of the proximal ulna. Although rare, intraosseous schwannoma should be considered in the differential diagnosis of radiographically benign-appearing osseous tumours in the bone. The cement technique is recommended for the treatment of intraosseous schwannoma.

Abstract:

Perilunate dislocation and fracture dislocations are rare injuries corresponding to 10% of all carpal injuries. They usually come with high-energy trauma, with associated injuries representing 61%. Volar lunate dislocation or fracture-dislocation accounts for 3% of perilunate injuries. We present a case of a 42-year-old polytrauma male, transmitted to our department 48 hours after a car accident with a trans-scaphoid volar lunate dislocation. During operation, the lunate was displaced volarly to the ulnar side of the wrist, forward to the styloid process of the distal ulna, while the scaphoid fracture appeared at the waist with comminution, and the proximal pole of the scaphoid protruded under the dorsal capsule. Carpal injuries are often missed out in polytrauma patients, and these injuries are underestimated because of the severity of the other visceral or extremity lesions. Untreated or improperly treated, those injuries lead to serious morbidity and loss of function. Therefore, good functional prognosis with decreased percentage of complications can be achieved following early recognition and early open surgical ligamentous complex repair.

Abstract:

Triceps tendon avulsion is a rarely occurring tendinous injury. Various surgical procedures, such as repair using sutures through the transosseous tunnel or suture anchors, have been reported for treating triceps tendon avulsion. However, standard surgical treatment has not yet been established. Here, we present a case of triceps tendon avulsion treated using the suture bridge technique. A 58-year-old man who fell on his left elbow from standing height presented to our hospital. Plain radiography revealed an avulsion fracture of the left olecranon process, suggesting triceps tendon avulsion. We performed surgical repair of the avulsed bone fragments and ruptured triceps tendon. We inserted suture anchors into the ulna, proximal to the fracture site, and passed the sutures through the full thickness of the triceps. Subsequently, fracture fragments were reduced and fixed by pulling them together with the triceps. We inserted knotless anchors into the ulna distal to the fracture site and fixed the avulsed bone fragments and triceps tendon using the suture bridge technique. The patient recovered well in five months and reported no elbow pain or limited range of motion. This suture bridge technique is advantageous as it prevents iatrogenic fracture and knot irritation, and it would be indicated in cases with poor bone quality or thin skin soft tissue of the olecranon.

Background:In general, fractures of the coronoid process are rare and usually occur in combination with additional elbow joint injuries. The treatment of these injuries aims to regain a stable as well as a flexible and loadable joint. Although there is currently little evidence, therapy recommendations remain controversial. Therefore, the aim of this study was to prognostically determine relevant factors for therapy recommendation by analysing a representative patient population of two trans-regional trauma centres.Material and Methods:Seventy-seven patients with a fracture of the coronoid process were treated within an 8-year period (2001 to 2009). After an average of 48 months (SD 31), treatment outcome of 58 patients (75%) was acquired. The results were statistically analysed.Results:The average age of the patient was 51.8 years (SD 13.6); 36 were male and 34 had a fracture on the right arm. Applying the fracture types of the coronoid process in accordance with Regan/Morrey, the result was: Type I (19), II (17) and III (22). Further injuries were also detected: 40 radial head fractures, 17 proximal ulnar fractures and 2 fractures of the olecranon. A luxation was detected in 44 of the 58 patients (76%). The patients’ average MEPS (Mayo Elbow Performance Score) was 80.6 points (SD 18), with significant differences between the various therapy strategies. Fifteen% of the coronoid process fractures were reconstructable to a limited extent only by means of osteosynthesis. In 33% of the patients, instabilities remained. The average extension/flexion came to 107° (SD 28), and pronation and supination 153° (SD 38).Conclusion:At present, a surgical therapy of ligamentary injuries cannot be statistically justified. A stable osseous reconstruction appears to make more sense. The strongest negative prognostic parameters in our patient population were: therapy with an external fixator, immobilisation for more than 21 days, the occurrence of complications and unstable osteosyntheses on the coronoid process.

Abstract:

Fractures sustained from a fall down stairs have received little attention in the orthopaedic literature. We have undertaken a study of these fractures to determine their epidemiology and to compare it to that of fractures caused by a standing fall. All new patients presenting with a fracture between July 2007 and June 2008 were prospectively identified. Falls down stairs caused 261 fractures and were the fifth commonest mode of injury in all ages but the second commonest in those aged 65 years or over. Patients in this category were significantly younger than those with a fracture from a standing fall (54.6 yrs versus 64.9 yrs, P<0.001). Fractures of the ankle (odds ratio (OR) 1.9, P<0.001), talus (OR 3.0, P=0.04), calcaneus (OR 9.7, P<0.001), midfoot (OR 6.9, P<0.001), toe phalanges (OR 12.0, P<0.001), scapula (OR 4.6, P=0.002), and proximal ulna (OR 2.4, P=0.04) were significantly more likely to result from a fall involving stairs. When grouped together, the odds of any foot or ankle fracture resulting from a fall down stairs were approximately double when compared with a fall from standing (OR 2.1, P<0.001). There was a trend towards increased fracture incidence from falls down stairs with worsening social deprivation (r=0.63, P=0.05). A fall down stairs poses a substantial risk of fractures of the foot, ankle, and scapula. When examining patients with this mechanism of injury, these fracture types should be excluded.
