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.

埋藏的经髁锁定螺钉确保稳定的固定和良好的业主报告的犬肱骨髁骨折的结果。
目的:报道埋入式经髁锁定螺钉治疗犬肱骨髁骨折的应用、并发症和长期疗效。方法:回顾性评估医疗记录(2013年10月至2024年4月)的信号、骨折形态、稳定、并发症和功能结局。影像学评估螺钉大小与髁突高度的关系。通过狗的利物浦骨关节炎评分和摩尔斯问卷来评估长期结果。结果:共纳入26只犬,肱骨髁外侧骨折14只,内侧骨折1只,T型或Y型骨折11只。放置26枚经髁螺钉,辅助固定包括电镀和/或克氏针。螺钉与髁突高度比中位数为0.338。在随访的20只狗中,10只实现骨完全愈合,9只愈合,1只未愈合,平均时间为43天。并发症发生率为55%。主要I型并发症5例,主要II型并发症2例,轻微并发症4例。并发症中仅1例与经髁螺钉直接相关,为螺钉松动。15例肱骨髁骨折的长期随访(范围356至3739天)显示,犬利物浦骨关节炎的中位评分为1分,大多数犬恢复了良好至优异的活动能力。结论:本研究的结果支持使用埋入式经髁锁定螺钉治疗肱骨髁骨折。临床意义:该方法提供稳定的固定和最小的特定并发症,根据业主问卷,产生良好的长期结果。

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.
