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 Objective This study is a case description of the clinical application of locking plates to repair fractures in the radius and ulna of a 9-month-old, male domestic rabbit. Study Design This study is a case report. Results Double-threaded locking adaptation plates of 1.5 mm were fixated to the radius and ulna of the rabbit using the principles of orthogonal plating. Radiographs of the left radius and ulna were obtained at 8 weeks postoperatively depicting complete osseous union of the fracture and no implant complications were observed. Clinical Significance The authors describe the first clinical report of 1.5 mm locking adaptation plates having been used in repairing radius and ulna fractures in a domestic rabbit.

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.

Background: Concomitant distal radius and distal ulna metaphysis or head fractures (DRUF) are uncommon and acceptable results have been reported from cast immobilisation and internal fixation. Methods: We reviewed the charts of 1094 patients treated for distal radius fracture at our institution in a two year period from 2009 to 2010. 24 patients with concomitant DRUF with were treated by cast immobilisation (group 1, n = 11), internal fixation of both bones (group 2, n = 7), internal fixation of radius alone (group 3, n = 2), and internal fixation of radius with distal ulna resection (group 4, n = 4). Patients treated by surgery underwent intraoperative assessment of distal ulna stability to determine the indication for ulna fixation. Post surgical range of motion, clinical parameters, and functional outcome scores (Gartland-Werley and modified Mayo) were measured. Results: Wrist motion was comparable in each group. Radiographic parameters were better in surgical groups. 23 of 24 patients achieved excellent/good outcomes based on Gartland-Werley scores, while 12 of 24 achieved good modified Mayo wrist score. There was a case of distal ulna non-union in group 1, and another case of delayed distal radius union in group 2. Conclusions: By evaluating patients’ functional requirement, and dynamic fluoroscopy examination, satisfactory outcomes can be achieved for various presentations of DRUF.

Background: Radius-ulna is the most frequently fractured bone of the pectoral limb in dogs with high predisposition to distal fractures. The smaller size of the distal fragment and open physis restrict the use of rigid fracture fixation techniques in distal fractures of growing dogs. Titanium elastic nails (TENs) are recommended in medical practice to stabilize long bone fractures in children. There is paucity of literature on TENs for the repair of radius-ulna fractures in dogs. Methods: This clinical study enrolled 10 dogs (7 grey hound and one each of Crossbred, Pomerenarian and Siberian Husky) suffering from distal radius-ulna (6 transverse and 4 short oblique) fractures since a mean ± SD duration of 3.40±4.5 days. The mean ± SD age and body weight of the dogs was 12.60±6.45 months and 14.09±6.41 Kg, respectively. All except one fracture was stabilized with two TENs inserted into the medullary canal of radial bone in a normograde manner from distal to proximal end using open cranio-lateral surgical approach. Result: Majority fractures achieved satisfactory reduction (n=8), radiographically. Weight bearing scores on walking increased gradually from day 12 (1.62 ± 1.51) to 45th (2.57±1.51), day 60th (3.75±0.5) and day 90 (4.0±0). Five dogs had uneventful recovery whereas remaining had major (n=2) or minor (n=3) complications. The length of the operated bone was non-significantly lesser as compared to contralateral healthy bone on day 60. Goniometric assessment of carpal joint of operated limb showed restricted range of motion on day 12 that improved to the near normal as contralateral healthy limb on day 60. Long-term results showed full (9) and acceptable (1) functional outcome. In conclusions, the TENs technique is simple and less invasive alternative fixation technique for distal radius-ulna fractures in young and light weighing dogs. As per authors, this is the first report on the use of TENs for the management of radius-ulna fracture in dogs.
