Glenoid bone loss presents a major risk for glenohumeral instability that has been well recognized as a cause of instability recurrence after attempted Bankart repair, and although most surgeons consider the Latarjet procedure as the gold standard, failures can occur with this technique as well and the search for alternative grafts to address glenoid bone loss is a major topic of ongoing research in the field. Of these techniques, the distal tibia allograft (DTA) has been shown to provide an excellent option to restore glenoid biomechanics, due to its congruency with the humeral head, dense bony quality, and the facility of harvest. The correct preparation of the DTA is essential to provide the most anatomic reconstruction possible and to avoid damage to the graft. The purpose of this Technical Note is to present our technique for cutting the DTA in detail, using a special workstation to optimize this procedure.
肩胛盂骨缺损是导致盂肱关节不稳定的主要风险因素，这一因素已被公认为是Bankart修复术后不稳定复发的原因之一。尽管大多数外科医生认为Latarjet手术是金标准，但该技术也可能失败，因此寻找替代移植物来解决肩胛盂骨缺损问题是该领域正在进行的研究的一个主要课题。在这些技术中，胫骨远端异体骨（DTA）已被证明是恢复肩胛盂生物力学的极佳选择，这是由于其与肱骨头的一致性、致密的骨质以及取材的便利性。正确制备DTA对于尽可能进行最解剖学的重建并避免移植物受损至关重要。本技术说明的目的是详细介绍我们使用特殊工作站优化该操作来切割DTA的技术。
