盂肱关节后脱位伴反向Hill-Sacks损伤: 1例报告和综述

Posterior shoulder dislocation with inverse Hill-Sacks lesion: A case report and literature review

摘要:

盂肱关节后脱位（posterior shoulder dislocation, PSD）指因盂肱关节前方受到直接向后的作用力或外伤时盂肱关节处于极度内收内旋位导致的肱骨头向肩胛骨关节盂后脱出的病变。相较于盂肱关节前脱位更为罕见，且漏诊、误诊率较高。临床上常伴有肱骨头内侧的明显缺损，即反 Hill-Sacks 损伤。本文通过收治盂肱关节后脱位伴反 Hill-Sacks 损伤案例 1 例，总结临床资料并进行文献综述，以期为 PSD 的治疗提供参考。

Abstract:

Posterior shoulder dislocation (PSD), also known as posterior glenohumeral dislocation, refers to that the humeral head is displaced out the posterior margin of posterior glenoid fossa under direct backward forces in extreme adduction and internal rotation posi- tion. Compared with anterior glenohumeral dislocation, PSD is considerably rare, while with significantly higher rate of missed diagnosis and misdiagnosis. Clinically, PSD is frequently accompanied with obvious bone defects of the anterior humerus head, namely reverse HillSacks lesion. In this paper, we reported one case of acute posterior glenohumeral dislocation with reverse Hill- Sacks lesion was treated non-operatively, additionally the relative literatures were reviewed in order to provide reference for the clinical management of PSD.
