Acquired acromial compromise, including thinning (less than 30% of the normal acromion) or fragmentation resulting from acromiohumeral impingement or previous acromioplasty, is a concern in reverse shoulder arthroplasty (RSA). This condition may lead to shoulder pain and difficulties in arm elevation because of acromial insufficiency fracture.

获得性肩峰受损（包括变薄和碎裂）与反向肩关节置换术后的不良结果无关。


获得性肩峰受损，包括肩峰变薄（小于正常肩峰的 30%）或因肩峰撞击或既往肩峰成形术导致的碎裂，是反向肩关节置换术 (RSA) 中的一个问题。这种情况可能会因肩峰机能不全骨折而导致肩部疼痛和手臂抬高困难。
