The Buford complex is an anatomic variation defined as the association of a cordlike middle glenohumeral ligament (MGHL) and an absent anterosuperior labrum. It can be challenging to properly identify on preoperative imaging and remains mostly an arthroscopic finding. It may, however, lead to problematic situations when encountered during an arthroscopic soft-tissue stabilization procedure, as the treatment of choice in such cases is a bone block. Moreover, reattaching the MGHL to the anterior border of the glenoid rim has traditionally not been recommended because it theoretically leads to severe restriction in external rotation. This technical note describes arthroscopic stabilization for anterior traumatic glenohumeral instability associated with the Buford complex. The cordlike MGHL is used to reconstruct a neo-labrum, associated with an anteroinferior glenohumeral ligament plication. Glenohumeral stabilization using the cordlike MGHL of the Buford complex may be an efficient alternative to a bone block procedure.
布福德复合体是一种解剖变异，定义为条索状的肱盂中韧带（MGHL）与前上盂唇缺如同时存在。术前影像学检查很难准确识别，大多仍是关节镜检查时的发现。然而，在关节镜下软组织稳定手术中遇到这种情况时可能会引发问题，因为此类病例的首选治疗方法是植骨块。此外，传统上不建议将MGHL重新附着于肩胛盂边缘的前缘，因为理论上这会导致严重的外旋受限。本技术说明描述了与布福德复合体相关的创伤性前向肱盂关节不稳的关节镜下稳定手术。使用条索状MGHL重建新盂唇，并对肱盂下前韧带进行折叠。利用布福德复合体的条索状MGHL进行肱盂关节稳定手术可能是植骨块手术的一种有效替代方法。
