盂肱下韧带后束损伤肱骨大结节骨折1例报告

Fracture of greater tubercle of humerus with posterior bundle injury of inferior glenohumeral ligament: a case report

摘要:

盂肱韧带是维持肩关节稳定性的重要组成部分，包括盂肱上、中、下韧带三部分，被动地维持肩关节下方的稳定性。其中，盂下肱韧带是最关键的部分，约占肩关节不稳因素的25%，盂肱下韧带分为前束、腋窝和后束，前束损伤较为为常见，约占93%，盂肱下韧带后束损伤约占7%。临床上盂肱下韧带很少造成单独损伤，更多的是合并有肩关节内其他组织损伤，如盂唇损伤、肩袖损伤、骨折等，临床上诊断较难，极易漏诊[。本文报道1例带线锚钉修复盂肱下韧带后束、肱骨大结节骨折复位缝线桥技术固定病例。希望引起骨科同行警惕，尽量避免类似损伤漏诊。该研究已告知患者并获得知情并签署同意书。

Abstract:

Glenohumeral ligament is an important part to maintain the stability of shoulder joint, including the upper glenohumeral, middle and lower ligaments, which passively maintain the stability of the lower shoulder joint.Among them, the subglenohumeral ligament is the most critical part, accounting for about 25% of the instability factors of the shoulder joint. The inferior glenohumeral ligament is divided into anterior bundle, axillary bundle and posterior bundle. The anterior bundle injury is more common, accounting for about 93%, and the posterior bundle injury of the inferior glenohumeral ligament accounts for about 7%.Clinically, the glenohumeral ligaments rarely cause single injury, but more often are combined with other tissue injuries in the shoulder joint, such as glenolip injury, rotator cuff injury, fracture, etc., which is difficult to diagnose clinically and easy to miss diagnosis.This paper reports a case of repairing the posterior bundle of inferior glenohumeral ligament with wire anchor and fixing the fracture of greater tubercle of humerus with suture bridge technique.It is hoped to arouse the vigilance of orthopaedic colleagues and avoid the missed diagnosis of similar injuries.Patients were informed of the study and obtained informed and signed consent forms.
