Recurrent posterior instability of the shoulder can be difficult to diagnose and technically challenging to treat. Although not as common as anterior instability, recurrent posterior shoulder instability is prevalent among certain demographic and sporting groups, and may be overlooked if one is not aware of the typical examination and radiographic findings. The diagnosis itself can be difficult as patients typically present with vague or confusing symptoms, and treatment has evolved from open to arthroscopic surgical techniques. This article is intended to review the anatomy and biomechanics associated with posterior shoulder instability, to discuss the pathogenesis and presentation of posterior instability, and to describe the variety of treatment options and clinical results.
复发性肩后不稳定较难诊断，且技术上具有挑战性。虽然不如前不稳定常见，但在某些人群和运动群体中，复发性肩后不稳定较为普遍，如果不了解典型的检查和影像学发现，可能会被忽视。诊断本身可能具有难度，因为患者通常表现出模糊或混淆的症状，并且治疗已经从开放式手术技术演变为关节镜手术技术。本文旨在回顾与肩后不稳定相关的解剖结构和生物力学，讨论后不稳定的发病机制和表现，并描述各种治疗选择和临床结果。
