Recurrent posterior glenohumeral instability, although a less common clinical entity than anterior instability, must be recognized and appropriately treated for a successful outcome. Pathologic findings that may need to be addressed include posterior Bankart lesions, humeral avulsion of the posterior inferior glenohumeral ligament (PIGHL), intrasubstance ligament attenuation, and combined lesions. In this review, we present 2 patients with the same pathoanatomic findings of recurrent posterior shoulder instability secondary to posterior humeral avulsion of the glenohumeral ligament with an associated posterior Bankart lesion. This combination of pathology is referred to as a "floating PIGHL" lesion. We review both patient's preoperative clinical findings and imaging studies and detail the necessary steps for a successful repair.
复发性肩后不稳定虽然比前不稳定少见，但必须识别并适当治疗，以获得良好的结果。可能需要解决的病理发现包括Bankart 后损伤、肱骨头后下盂唇止点撕脱（PIGHL）、盂唇内韧带变细和联合损伤。在本综述中，我们介绍了 2 例复发性肩后不稳定患者，其病理解剖学发现相同，均继发于肱骨头后下盂唇止点撕脱合并Bankart 后损伤，这种联合损伤被称为“漂浮 PIGHL”损伤。我们回顾了这 2 例患者的术前临床和影像学检查，并详细介绍了成功修复的必要步骤。
