The purpose of this study was to show the MR arthrographic imaging features of a normal anatomic variation of the shoulder: the absence of the anterior superior labrum and the presence of a "cordlike" middle glenohumeral ligament,which together are known as the Buford complex.
We retrospectively analyzed the MR arthrographic examinations of 10 patients with arthroscopically proven Buford complexes.
MR arthrographic examinations showed an absent anterior superior labrum and an associated cordlike middle glenohumeral ligament in all patients. No contiguous tear of the superior labrum or anterior inferior labrum was evident. Originally, this variation was mistakenly diagnosed as a labral avulsion in two of the 10 patients. Also, a differential diagnosis of a superior labral tear was mistakenly offered for four patients.
An absent anterior superior labrum and an associated cordlike middle glenohumeral ligament represent the normal variation that is known as the Buford complex rather than an avulsed labrum. This normal variation may be mistaken for a detached labrum.
本研究的目的是展示肩部正常解剖变异的磁共振关节造影成像特征：前上盂唇缺如以及存在“索状”肱盂中韧带，二者合称为布福德复合体。
我们回顾性分析了10例经关节镜证实为布福德复合体患者的磁共振关节造影检查结果。
磁共振关节造影检查显示，所有患者均存在前上盂唇缺如及相关的索状肱盂中韧带。未见上盂唇或前下盂唇连续撕裂。最初，10例患者中有2例该变异被误诊为盂唇撕脱。另外，有4例患者被错误地诊断为上盂唇撕裂。
前上盂唇缺如及相关的索状肱盂中韧带代表了被称为布福德复合体的正常变异，而非撕脱的盂唇。这种正常变异可能被误认为是分离的盂唇。
