To assess whether Bare Spot is previously displaced by proportion (MEASURE BP-A × 1.25/MEASURE BP-P = 1).
35 patients with surgical indication for rotator cuff injury repair were evaluated. The distances from the Bare Spot to the anterior edge of the glenoid cavity (BS-A) and to the posterior edge (BS-P) were measured by arthroscopy and computed tomography with three-dimensional reconstruction of the scapula.
The distance from the Bare Spot to the anterior border (BS-A tc) was 11.6 mm with a median 12 mm; The distance to the posterior border (BS-P tc) was on average 15.5 mm with a median 15 mm. The distances from BS to anterior cavity edge measured by arthroscopy were on average (BS-A video) 12.25 mm with a median of 12 mm, and from BS to posterior edge (BS-P video) 16.25 mm on average with median 16 mm ( < 0.005).
Bare Spot is displaced anteriorly at a proportion of 40% of the anterior margin and 60% of the posterior margin.
评估裸区是否先前按比例移位（测量BP - A×1.25 /测量BP - P = 1）。
对35例有肩袖损伤修复手术指征的患者进行评估。通过关节镜检查和肩胛骨三维重建的计算机断层扫描测量裸区到肩胛盂前缘（BS - A）和后缘（BS - P）的距离。
裸区到前缘（BS - A tc）的距离为11.6毫米，中位数为12毫米；到后缘（BS - P tc）的距离平均为15.5毫米，中位数为15毫米。通过关节镜测量的从裸区到前盂缘的距离平均为（BS - A video）12.25毫米，中位数为12毫米，从裸区到后缘（BS - P video）平均为16.25毫米，中位数为16毫米（<0.005）。
裸区向前移位，占前缘的40%和后缘的60%。
