It is still unclear whether diabetic mellitus (DM) is associated with rotator cuff lesions. The object of this retrospective study was to compare the ultrasonographic (US) findings of rotator cuffs in diabetic patients with those of nondiabetic patients with chronic shoulder pain. In total, 419 patients (80 diabetic, 339 nondiabetic) who had chronic shoulder pain and had been referred to receive US examination between January 2005 and January 2008 in a medical center were included in this study. The US findings of rotator cuff lesions were classified into two main categories: rotator cuff tears (RCTs) and calcifying tendinopathy (CT). In total, 114 (25.2%) shoulders with CT of the rotator cuff and 160 (35.3%), 15 (3.3%) and 5 (1.1%) shoulders with supraspinatus, infraspinatus and subscapularis tears, respectively, were noted. No difference in the ratio of tears of RCTs was found on US examinations between two groups. The crude odds ratio (OR) for CT of diabetic patients was 1.85 (p = 0.014); however, the adjusted OR for CT in diabetic patients became insignificant after controlling for the other variables (OR = 1.59, p = 0.08). To our knowledge, this is the first study to explore US findings among diabetic and nondiabetic patients with chronic shoulder pain. Further study is advised to confirm our findings.
