The management of intraoperative posterior instability during total shoulder arthroplasty includes soft tissue balancing, reduction of humeral component retroversion, and augmentation of posterior glenoid defects. Severe instability caused by incompetence of the posterior capsule may require plication of the capsular remnant or a posterior muscle to the glenoid or proximal humerus. A technique of posterior capsulorrhaphy to the proximal humerus is described that does not require a separate surgical approach. By restoring stability, early range of motion exercises can be instituted, eliminating the need for postoperative immobilization. Posterior stability should be assessed during all total shoulder arthroplasties.
全肩关节置换术中术中后方不稳定的处理包括软组织平衡、减少肱骨假体后倾以及增加肩胛盂后方缺损的修补。后方关节囊功能不全导致的严重不稳定可能需要将关节囊残余部分或后方肌肉折叠缝合至肩胛盂或肱骨近端。本文描述了一种肱骨近端后方关节囊缝合技术，该技术无需单独的手术入路。通过恢复稳定性，可以尽早开始进行活动度练习，从而无需术后制动。在所有全肩关节置换术中均应评估后方稳定性。
