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:
Le cubitus proximal détient une courbe sagittale unique pour chaque individu, nommée « Proximal Ulna Dorsal Angulation (PUDA) ». Une reconstruction non-anatomique du cubitus proximal, suite à une fracture complexe peut engendrer une malunion, de l’arthrose et de l’instabilité. L’objectif de cette étude était d’évaluer la magnitude de malalignement au niveau de l’angulation proximale dorsale du cubitus qui causerait un malalignement radio-capitellaire, avec et sans un ligament annulaire intact. Afin d’atteindre cet objectif, une étude biomécanique fut conduite sur six spécimens frais congelés avec un simulateur de mouvement du coude. Des fractures simulées au niveau du PUDA, furent stabilisées avec une fixation interne dans cinq configurations différentes. Des images fluoroscopiques furent prises dans différentes positions du coude et de l’avant-bras, avec le ligament annulaire intact, puis relâché. Le déplacement de la tête radiale fut quantifié avec le ratio radio-capitellaire. Une interaction significative fut découverte entre les positions du coude, les angles de malalignement et l’intégrité du ligament annulaire. La subluxation de la tête radiale fut accentuée lors de la déchirure du ligament annulaire. Une augmentation de la subluxation antérieure de la tête radiale fut observée lorsque le malalignement était fixé en extension et lors de mouvements de flexion progressive du coude. D’autre part, un malalignement en flexion et une extension graduelle du coude occasionnait une subluxation postérieure. En conclusion, les résultats ont démontré l’importance d’une reconstruction anatomique du cubitus proximal, car un malalignement de 5 degrés engendre une subluxation de la tête radiale, surtout lors d’une déchirure du ligament annulaire.
It has been shown that the proximal ulna has a sagittal bow, named the Proximal Ulna Dorsal Angulation (PUDA), unique for each individual. Non-anatomic reconstruction of the proximal ulna following a complex injury may lead to malunion, arthrosis and instability, hence the importance of understanding its initial anatomy. The purpose of this study was to evaluate the magnitude of angular malalignement at the proximal ulna dorsal angulation that would lead to radiocapitellar malalignement, with and without an intact annular ligament. In order to achieve our goal, a biomechanical study was conducted on six fresh frozen specimens, with an elbow movement simulator. Simulated fractures at the PUDA were stabilized with internal fixation at five different angles. Then, fluoroscopic images were taken in different elbow and forearm positions, first with the annular ligament intact and then released. Radial head displacement was quantified with the Radio-Capitellar-Ratio (RCR). Overall, a significant interaction was found between elbow positions, angles of malalignement and annular ligament integrity. Radial head subluxation was emphasized when the annular ligament was ruptured. Moreover, anterior subluxation of the radial head increased as malalignement was fixed into extension and with progressive elbow flexion. Furthermore, posterior subluxation increased with malalignement into flexion and with elbow extension. In conclusion, our results demonstrate the importance of obtaining an anatomic reconstruction, specific for each individual’s unique proximal ulna dorsal angulation, following a proximal ulna fracture. Indeed, malalignment of 5 degrees can lead to abnormal tracking of the radial head, especially when associated with annular ligament tear.

Abstract:
The forearm is a complex quadrilateral structure linked by the proximal and distal radioulnar joints, ligaments, which include the interosseous membrane and triangular cartilage, and several obliquely orientated muscles. A displaced fracture or ligament rupture within this forearm is likely to involve other structures. Treatment requires anatomic recovery of stable function. The ulnar corner can sustain fractures or ligament ruptures which affect stable, pain-free, congruous forearm rotation. The distal radius may fracture after high- or low-energy trauma; anatomic reduction may not be essential in all; inaccuracy may lead to loss of rotation and ulnocarpal abutment but long-term arthritis is unusual. Children’s fractures are managed with consideration of remodeling potential. The scaphoid is vulnerable to non-union; plaster immobilization, early percutaneous fixation, and later bone-grafting all have roles. Salvage for osteoarthritic non-union may reduce pain but compromises function. Rupture of the carpal ligaments may cause substantial disruption and require complex reconstruction.

Abstract:
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.
