Objective The aim of this study was to describe a novel minimally invasive surgical approach for the treatment of shoulder osteochondritis dissecans (OCD) in dogs and to retrospectively review our clinical cases treated with this approach.

Study Design The study describes a modification of Cheli surgical approach (1985), developed to reduce the degree of invasiveness as well as the incidence of postoperative complications observed in other surgical approaches to the shoulder joint. Medical records of dogs that underwent our minimally invasive approach to the scapulohumeral joint for treatment of OCD from May 2001 to May 2019 were retrospectively reviewed for intraoperative findings and complications. Clinical outcome and complications were also evaluated in the operated dogs with a minimum of a 2-month-follow-up evaluation.

Results A total of 164 shoulders in 141 dogs (23 bilateral), 103 males and 38 females, were examined and treated with our modified craniolateral approach for the treatment of OCD of the humeral head. In all cases, the modified craniolateral approach allowed visibility and adequate exposure of the caudal humeral head surface. Radiographic and clinical follow-up evaluations were available in 123/164 (75%) cases. The clinical outcome was consistent with other reports using different surgical approaches for OCD lesions of the humeral head in dogs.

Clinical Significance This technique provided a reliable approach for surgical treatment of canine shoulder OCD and can be considered a valid alternative to other surgical approaches including arthroscopy.

目的 本研究的目的是描述一种新的微创手术方法，用于治疗犬肩部剥脱性骨软骨炎 (OCD)，并回顾性地回顾我们用这种方法治疗的临床病例。

研究设计 该研究描述了 Cheli 手术入路 (1985) 的改进，旨在降低在其他肩关节手术入路中观察到的侵入性程度以及术后并发症的发生率。回顾性审查了 2001 年 5 月至 2019 年 5 月接受我们的肩肱关节微创方法治疗强迫症的狗的病历，以了解术中发现和并发症。还对手术犬的临床结果和并发症进行了评估，至少进行了 2 个月的随访评估。

结果 141 只犬（23 只双侧），103 只雄性和 38 只雌性犬共 164 个肩部接受了我们改良的颅外侧入路治疗肱骨头强迫症的检查和治疗。在所有情况下，改良的颅外侧入路允许可见性和充分暴露肱骨头尾部表面。123/164 (75%) 例患者进行了放射学和临床随访评估。临床结果与使用不同手术方法治疗犬肱骨头强迫症病变的其他报告一致。

临床意义 该技术为犬肩部强迫症的手术治疗提供了一种可靠的方法，可以被认为是其他手术方法（包括关节镜检查）的有效替代方法。
