Abstract

AbstractThe aim of this study was to report the outcome in a 6-year-old male English Setter dog that suffered a combination of divergent elbow dislocation and open distal ulnar fracture. This study is a case report. After surgical reduction in the elbow luxation, the dog was treated with the TightRope fixation system used as replacement of the lateral collateral ligament, a radioulnar positional screw, and external skeletal fixation. Removal of all implants was performed 3 months postoperatively. The 6-month follow-up visit found the dog without lameness, displaying normal activity, and with normal elbow range of motion and normal Campbell's test. Successful surgical management was achieved with good long-term results using TightRope, a positional screw, and an external skeletal fixator.

Divergent elbow dislocation is defined as an elbow luxation in which the distal humerus is forced between the proximal radius and ulna, resulting in separation or divergence of the proximal antebrachial bones.[1]
The elbow joint can be divided into three synovial joints: humeroradial, humeroulnar, and proximal radioulnar

Summary

Introduction

Divergent elbow dislocation is defined as an elbow luxation in which the distal humerus is forced between the proximal radius and ulna, resulting in separation or divergence of the proximal antebrachial bones.[1] The elbow joint can be divided into three synovial joints: humeroradial, humeroulnar, and proximal radioulnar. The direction of luxation is most common laterally because the medial epicondylar ridge of the humerus is larger than the lateral part and its articular surface is distally sloping.[7,8]
