Figure 4

Arthroscopic views. (a) Crater formation on the undersurface of the acromion and bleeding was noted from the subacromial erosion (arrows). (b) Irregularity of the greater tuberosity was observed. (c) Osteophytes of the greater tuberosity were removed by a shaver following coagulation of the bleeding points. (d) Bursal-side partial-thickness tear was not repaired (GT: greater tuberosity; DL: deep layer of the cuff; SL: superficial layer of the cuff).
