Abstract

Objective: To determine outcome, report complications, and risk factors for complications associated with the surgical treatment of fractures of the lateral aspect of the humeral condyle (FLHC) in dogs. Study design: Fifty dogs with FLHC that had been repaired surgically were included in this retrospective case series. Methods: The medical records and radiographs from 50 dogs with FLHC from 1990-2006 were analyzed. Results: The complication rate was 30%. For every 30-minute increase in surgical time the odds of a complication increased by 2.00 (95% Cl: 1.06, 3.77). For every 10° increase in the angle between the transcondylar screw and a line between the epicondyles viewed on a craniocaudal radiograph there was a 4.82 (95% Cl: 1.23, 18.86) greater odds of an intracondylar fracture gap appearing on post-operative radiographs. When an intracondylar fracture gap was present after surgery there was a 25% long-term radiographic outcome failure rate, whereas there was a 0% radiographic failure rate in the dogs in which an intracondylar fracture gap was not present. In conclusion, transcondylar screw placement parallel to the epicondylar line should be attempted for the repair of FLHC. An increase in surgical time leads to an increase in post-operative complication rate. The presence of an introcondylar fracture gap may be associated with fracture failure. Clinical significance: Screw angulation predisposed to post-operative intracondylar fracture gap which in turn may be associated with higher fracture fixation failure rate. The dogs that hod prolonged surgical times had an increased complication rate.
