Critical glenoid bone loss in the setting of glenohumeral instability presents a challenging problem for shoulder surgeons. In these cases, bone augmentation procedures are necessary to reconstruct the native glenoid and to maintain stability and function. Although the Latarjet procedure has good outcomes, the coracoid is not always large enough for full reconstruction of the glenoid. Alternative structural graft techniques have been developed over the years, including distal tibia allograft and iliac crest autograft, yet both of these techniques have several limitations. Due to the supply constraints associated with current graft options, introducing other options that mitigate these limitations is beneficial. In this technique and the accompanying video, we introduce the use of a distal radius allograft for glenoid reconstruction in the setting of glenohumeral instability. The distal radius allograft has a radius of curvature more closely matching that of the native glenoid, with anatomic features that can allow for enhanced glenohumeral stability, making it a promising option for this challenging problem.
在肩关节不稳的情况下，关键的肩胛盂骨丢失给肩关节外科医生带来了一个具有挑战性的问题。在这些病例中，骨增强手术对于重建天然肩胛盂以及维持稳定性和功能是必要的。尽管Latarjet手术有良好的效果，但喙突并不总是足够大以完全重建肩胛盂。多年来已经开发了替代的结构性移植技术，包括异体远端胫骨移植和自体髂嵴移植，但这两种技术都有一些局限性。由于当前移植选择相关的供应限制，引入其他减轻这些局限性的选择是有益的。在这项技术及随附视频中，我们介绍了在肩关节不稳的情况下使用异体远端桡骨进行肩胛盂重建。异体远端桡骨的曲率半径与天然肩胛盂的曲率半径更接近匹配，其解剖特征可增强肩关节稳定性，使其成为解决这一具有挑战性问题的一个有前景的选择。
