Abstract
Objective: To report the rate of survival, rate of return to racing, and quality of racing performance following surgical fixation of medial condylar fractures.
Study design: Retrospective study.
Animals: A total of 150 Thoroughbred and Standardbred racehorses surgically treated for medial condylar fracture (100 lag screw fixation, 50 plate fixation).
Methods: Medical records, radiographs, and racing databases (2000-2020) were reviewed to collect signalment, fracture characteristics, fixation methods, survival rate, and complication rate. Change in racing performance was assessed using Wilcoxon rank sum tests.
Results: The short-term survival, long-term survival, and complication rates were 98.7% (148/150), 93.3% (140/150), 12.0% (18/150), respectively. Four horses died of fatal complications, four died from unknown causes, and two were lost to follow up. The prognosis for returning to racing was 71.3% (107/150) (80/100, 80.0% for lag screw fixation; 27/39, 69.2% for plate fixation with plate removal). Post-injury total number of races increased (lag screw fixation) (p < .001) or did not change (plate fixation) (p = .320); post-injury total earnings, average earnings/race, and average speed figure did not change for either fixation type. Additionally, 78.0% of horses increased or maintained their highest race class. Horses with spiral fractures were less likely to return to racing than those with sagittal fractures.
Conclusion: Survival rate was excellent and the rate of returning to racing was favorable, with no decline in performance following injury.
Clinical significance: Owners can expect horses to return to racing in most cases and perform as successfully as they did prior to fracture.
期刊介绍：
Veterinary Surgery, the official publication of the American College of Veterinary Surgeons and European College of Veterinary Surgeons, is a source of up-to-date coverage of surgical and anesthetic management of animals, addressing significant problems in veterinary surgery with relevant case histories and observations.
It contains original, peer-reviewed articles that cover developments in veterinary surgery, and presents the most current review of the field, with timely articles on surgical techniques, diagnostic aims, care of infections, and advances in knowledge of metabolism as it affects the surgical patient. The journal places new developments in perspective, encompassing new concepts and peer commentary to help better understand and evaluate the surgical patient.
