Objective The aim of this study was to report the functional outcome and complications following transcondylar screw and epicondylar plate fixation of skeletally mature dogs with fractures of the lateral aspect of the humeral condyle using a string of pearls, limited contact dynamic compression plate (LC-DCP) or locking compression plate (LCP).

Study Design This study was a retrospective review of clinical records, radiographic images and canine brief pain inventory evaluation with a supplementary non-validated questionnaire.

Results Thirty-one fractures in 29 dogs were included. The majority of dogs were Spaniels (23/29). Thirty fractures had evidence of humeral intracondylar fissure. Sixteen fractures had string of pearls, eight LCP and seven LC-DCP. There were two minor complications and three major complications. Perioperative (median: 6 weeks, range: 6–12) outcome was considered fully functional for 24 fractures and acceptable for 6 fractures. One dog had an unacceptable outcome due to the failure of an LCP that healed following revision surgery. Fractures with radiographic follow-up had a persistent visible intracondylar fracture line in 20/26. Twenty-six of twenty-seven owners perceived an excellent outcome (median: 135 weeks, range: 25–246).

Conclusion Repair of fractures of the lateral aspect of the humeral condyle with a transcondylar screw and epicondylar plate has a good perioperative, mid- and long-term outcome with 10% major complication rate, despite incomplete or non-union of the intracondylar fracture in 20/26 elbows.

目的 本研究的目的是报告使用一串珍珠、有限接触动态加压钢板 (LC-DCP) 对肱骨髁外侧骨折的骨骼成熟犬进行经髁螺钉和上髁钢板固定后的功能结果和并发症。 ) 或锁定加压板 (LCP)。

研究设计 本研究是对临床记录、放射线图像和犬类简短疼痛库存评估的回顾性审查，并附有补充性未经验证的问卷。

结果 纳入29只犬31处骨折。大多数狗是西班牙猎犬（23/29）。三十处骨折有肱骨髁内裂的证据。16 处骨折有珍珠串，8 处 LCP 和 7 处 LC-DCP。有两个轻微并发症和三个主要并发症。24 处骨折的围手术期（中位数：6 周，范围：6-12）结果被认为是完全功能性的，6 处骨折可以接受。由于修复手术后愈合的 LCP 失败，一只狗的结果令人无法接受。放射学随访的骨折在 20/26 中具有持续可见的髁内骨折线。27 位业主中有 26 位认为结果非常好（中位数：135 周，范围：25-246）。

结论 使用 经髁螺钉和上髁钢板修复肱骨髁外侧骨折具有良好的围手术期、中长期结果，主要并发症发生率为 10%，尽管 20 年髁内骨折不完全或不愈合/26 肘部。
