Ulnar Fracture

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.

Introduction:The Monteggia fracture is a fracture to the proximal third of ulna associated with a radial head dislocation. Although this is well described and classified in adults, it is uncommon in children. Identifying growth plate trauma and subsequent surgical management are of critical importance. This report identifies a unique variant of Monteggia fracture with a Salter-Harris Type I injury of the radial head instead of a dislocation, and how it was successfully stabilised with a closed reduction. Case Rport: We present a case of a nine 9 year-old female admitted to our unit with a deformed upper extremity following a fall from height. This was a closed and isolated injury without neurovascular compromise. Radiographs revealed a displaced fracture to the proximal ulna shaft. Unlike a true Monteggia, the radial fracture went through the proximal physis with anterior divergence of the distal fragment. The radiocapitellar joint remained congruent. The ulna fracture was stabilized with open reduction and plate osteosynthesis whilst the radial injury underwent closed reduction and intramedullary pinning with excellent outcomes and maintenance of full range of motion. Conclusion: This case highlights a new variant and successful outcome following a closed reduction intramedullary fixation technique in this emergent pattern of injury. We highlight the need for a classification of these fractures in children. Keywords: Case report, Monteggia, growth plate, pediatric, fracture, trauma, variant.

Monteggia fractures are rare in children, and subtle radial head dislocations, with minor plastic deformation of the ulna, may be missed in up to a third of cases. Complications of Monteggia fractures-dislocations include persistent radial head dislocation, forearm deformity, elbow stiffness, and nerve palsies at the time of presentation. An unusual case of median nerve palsy following elastic stable intramedullary nailing of a type I Monteggia lesion in a 6-year-old girl is presented, and we highlight that, although most nerve palsies associated with a Monteggia fracture-dislocations are treated expectantly in children, early intervention here probably provided the best outcome.

Abstract PurposeThe present study aimed to explore the influence of ulnar bow on the surgical treatment of Bado type I missed Monteggia fracture in children.MethodsThis study is a retrospective review of 24 patients between November 2010 and March 2019. All patients were treated with open reduction of the radial head and ulnar opening wedge osteotomy without annular ligament reconstruction. The mean interval between injury onset and surgery was five months (range: 2–12 months). The average age of participants at the time of surgery was 6.4 years (range: 3–10 years). We evaluated the maximum ulnar bow (MUB) and MUB position (P-MUB) via radiography. The patients were divided into middle group (group A: 14 cases, MUB located at 40% to 60% of the distal ulna) and distal group (group B: 10 cases, MUB located at 20% to 40% from the distal end of the ulna) based on P-MUB. The mean period of follow-up was 37 months (range: 6–102 months).ResultsAt the last follow-up, all the children showed stable reduction of the radial head, and the flexion function of elbow joint improved after operation (P<0.05). Group A presented a larger the ratio of maximum ulnar bow(R-MUB) and angle of ulnar osteotomy(OA) than group B (P<0.05). There was statistically significant difference between group A and Group B in the P-MUB (P < 0.05). The osteotomy angle was positively correlated with the R-MUB (R2 =0.497,P=0.013), The osteotomy angle was positively correlated with the P-MUB (R2=0.731,P=0.000), The R-MUB is proportional to the P-MUB (R2 =0.597,P=0.002). The regression equation of P-MUB and osteotomy angle: Angle=7.064+33.227* P-MUB (R2=0.459, P =0.000).ConclusionWhen the ulnar bow is positioned at the middle ulna, a stable reduction of radial head need to be achieved through a larger angle in the ulnar osteotomy. If the position of maximum ulnar bow (P-MUB) is closer to the middle of the ulna or the ratio of maximum ulnar bow (R-MUB) is larger, the osteotomy angle is larger.

Chapter 15 discusses radius and ulna trauma. Forearm fractures are common and may be isolated to the ulna or more commonly involve both bones. Fractures of the radius or ulna are usually because of direct trauma and are often displaced. Depending on their complexity, isolated fractures of the ulnar diaphysis may be treated nonoperatively or operatively whereas both bone (radius and ulna) diaphyseal fractures are typically treated operatively. Galeazzi fracture-dislocations are comprised of radial diaphyseal fractures in association with distal radioulnar joint (DRUJ) dislocation/subluxation. Monteggia fracture-dislocations are comprised of a proximal ulnar fracture in association with radial head dislocation. In type IV Monteggia injuries, there is an additional fracture of the proximal radial diaphysis. Essex-Lopresti fracture-dislocations include radial head fractures in association with DRUJ dislocation/subluxation.

Two litters of Germanshepherd dogs were evaluated for a haemorrhagic tendency that was characterised by excessive bleeding from the umbilicus at birth, haemorrhage and haematoma formation at vaccination, excessive bruising, and lameness due to haemarthrosis. Platelet counts, clotting times and Von Willebrand's factor (VWF) assays were assessed in all dogs. Factor VIII determination was performed in 1 puppy and its parents. Based on the clotting times and VWF assay, 6 puppies (4 male and 2 female) showed type I Von Willebrand's disease (VWD), 5 (4 male and 1 female) possible type II VWD, and 4 were unaffected. One puppy with possible type II VWD had very low factor VIII activity; its sire had a normal factor activity, whereas the dam was in the low-normal range. This article reports type I and possible type II VWD in 2 related litters of German shepherd dogs, the latter being rare in German shepherd dogs.

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.

Objectives The aim of this study was to describe the demography, aetiology, location and classification of physeal fractures in cats, and to describe their management and outcomes. Methods Clinical records and radiographs of cats referred for management of physeal fractures were retrospectively reviewed. Fractures of the proximal femoral physis were excluded. Descriptive statistics were used to describe signalment, cause of injury, presence of concurrent injuries, fracture description, treatment modality, complications, follow-up, physeal closure, implant removal and outcome. Results Thirty-four cats with 36 fractures were included, of which 17 affected the distal femur, 11 the distal tibia and fibula, five the distal radius and ulna, two the proximal tibia and one the distal humerus. Salter–Harris classification was type I in 14, type II in 16, type III in two and type IV in four fractures. Thirty-four fractures were treated with primary fixation, and the most common method was crossed Kirschner wires (24/34 fractures). Complications were observed in 14 fractures, of which 12 were minor. At radiographic follow-up, physeal closure was reported in 23 fractures, of which 15 were considered premature. Implant removal was performed in three fractures. Outcome was good in 28, fair in four and poor in two fractures. Conclusions and relevance Fracture of the distal femoral physis was the most common physeal fracture seen. Cats presenting with physeal fractures may be skeletally immature or mature with delayed physeal closure. The rate of physeal closure after fracture repair was relatively high but without apparent impact. The frequency of implant removal was very low, indicating that despite having a physeal fracture repair, most cats did not require a second procedure to remove implants. Overall, internal fixation provided a good outcome in most fractures.
