Abstract：Objective To investigate the relationship between acromion index and degenerative full-thickness rotator cuff tears. Methods We enrolled 48 patients ( mean age: 66 years) diagnosed with full-thickness rotator cuff tears by magnetic resonance imaging and intraoperative arthroscopic findings between March 2014 and October 2017.Another 52 patients ( mean age: 63 years) with shoulder pain identified on magnetic resonance imaging induced by other shoulder diseases, such as frozen shoulder and instability, were enrolled as controls. Standardized, true anteroposterior radiographs were assessed by one radiologist. Two independent orthopedic surgeons, who were both blinded to the patients' diagnosis, measured the AI on all radiographs. Then we compared the AI between the 2 groups.Results The mean AI of the control and RCT groups were 0.65 and 0.71, respectively ( P ＜ 0.05, 95％ confidence interval). No differences were found between the AI of male ( 0.70) and female ( 0.69) in the RCT group ( P＞0.05). Conclusions AI is an effective predictive factor for degenerative full-thickness rotator cuff tears in an older population.
