This study was done to examine the association between shoulder adhesive capsulitis and chronic diabetic complications and diseases closely related to diabetes in Akdeniz University Hospital. Shoulder adhesive capsulitis were evaluated in 297 consecutive type II diabetic patients attending an outpatient diabetic clinic. Shoulder adhesive capsulitis was detected in 86 patients (29%). There was a significant association between shoulder adhesive capsulitis and limited joint mobility (p = 0.006), shoulder adhesive capsulitis and Dupuytren's disease (p = 0.003). Odds ratios (OR) for carpal tunnel syndrome, limited joint mobility, and Dupuytren's disease with shoulder adhesive capsulitis were respectively 1.4, 2.1, and 2.4 [95% confidence interval (CI), respectively, 0.7-2.9, 1.2-3.69, and 1.3-4.4]. Also, shoulder adhesive capsulitis was associated with the age of patients (p = 0.000) and the duration of diabetes (p = 0.03). When other associations between shoulder adhesive capsulitis and diabetic complications were compared, it was associated with retinopathy [p = 0.014, OR = 2.2 (95% CI 1.1-4.2)], but there was no association with neuropathy or macroproteinuria. On the other hand, the degrees of passive abduction, internal rotation, external rotation motions of shoulder joints in the all patients were correlated with age of patients, duration of diabetes, neuropathy, and the other hands' problems (Dupuytren's disease, limited joint mobility) (p<0.05). The presence of shoulder adhesive capsulitis may indicate presence of organ involvement.
