Abstract
Objective: To report the use, complications, and long-term outcomes of a buried transcondylar locking screw for the management of humeral condylar fractures in dogs.
Methods: Medical records were retrospectively assessed (October 2013 to April 2024) for signalment, fracture configuration, stabilization, complications, and functional outcomes. Screw size relative to condyle height was assessed radiographically. Long-term outcomes were evaluated through the Liverpool Osteoarthritis in Dogs score and Moores' questionnaire.
Results: 26 dogs were included: 14 with fracture of lateral part and 1 with fracture of the medial part of the humeral condyle, and 11 with T-or Y-shaped (T/Y) fractures. Twenty-six transcondylar screws were placed, with ancillary fixations including plating and/or Kirschner wiring. The median screw-to-condyle height ratio was 0.338. Of the 20 dogs with follow-up, 10 achieved full bone healing, 9 were healing, and 1 had not healed by a median of 43 days. The complication rate was 55%. Five major type I, 2 major type II, and 4 minor complications were recorded. Among the complications, only 1 was directly associated with the transcondylar screw and consisted of screw loosening. Long-term follow-up (range, 356 to 3,739 days) in 15 humeral condylar fractures showed a median Liverpool Osteoarthritis in Dogs score of 1, with most dogs regaining good to excellent mobility.
Conclusions: The results of this study supported the use of a buried transcondylar locking screw for the management of humeral condylar fractures.
Clinical relevance: This method provides stable fixation with minimal specific complications, yielding favorable long-term outcomes based on owner questionnaires.
期刊介绍:
The American Journal of Veterinary Research supports the collaborative exchange of information between researchers and clinicians by publishing novel research findings that bridge the gulf between basic research and clinical practice or that help to translate laboratory research and preclinical studies to the development of clinical trials and clinical practice. The journal welcomes submission of high-quality original studies and review articles in a wide range of scientific fields, including anatomy, anesthesiology, animal welfare, behavior, epidemiology, genetics, heredity, infectious disease, molecular biology, oncology, pharmacology, pathogenic mechanisms, physiology, surgery, theriogenology, toxicology, and vaccinology. Species of interest include production animals, companion animals, equids, exotic animals, birds, reptiles, and wild and marine animals. Reports of laboratory animal studies and studies involving the use of animals as experimental models of human diseases are considered only when the study results are of demonstrable benefit to the species used in the research or to another species of veterinary interest. Other fields of interest or animals species are not necessarily excluded from consideration, but such reports must focus on novel research findings. Submitted papers must make an original and substantial contribution to the veterinary medicine knowledge base; preliminary studies are not appropriate.
