We studied retrospectively a consecutive series of 547 shoulders in 529 patients undergoing operation for instability. In 41, the cause of instability was considered to be lateral avulsion of the capsule, including the inferior glenohumeral ligament, from the neck of the humerus, the HAGL lesion. In 35, the lesion was found at first exploration, whereas in six it was noted at revision of a previous failed procedure. In both groups, the patients were older on average than those with instability from other causes. Of the primary cases, in 33 (94.3%) the cause of the first dislocation was a violent injury; six (17.4%) had evidence of damage to the rotator cuff and/or the subscapularis. Only four (11.4%) had a Bankart lesion. In patients undergoing a primary operation in whom the cause of the first dislocation was a violent injury, who did not have a Bankart lesion and had no suggestion of multidirectional laxity, the incidence of HAGL was 39%.
我们回顾性研究了529例因肩关节不稳接受手术的患者的547个肩关节。其中41例，不稳的原因被认为是关节囊包括下盂肱韧带从肱骨头颈部外侧撕脱，即肱骨附着点盂唇肱韧带损伤（HAGL损伤）。35例在初次探查时发现该损伤，6例在先前手术失败后的翻修术中发现。两组患者的平均年龄均高于因其他原因导致肩关节不稳的患者。在初次病例中，33例（94.3%）首次脱位的原因是暴力损伤；6例（17.4%）有肩袖和/或肩胛下肌损伤的证据。只有4例（11.4%）有Bankart损伤。在初次手术的患者中，首次脱位原因是暴力损伤、没有Bankart损伤且无多向性松弛迹象的患者，HAGL损伤的发生率为39%。
