In addition to microand macroangiopathic complications, diabetes mellitus is also associated with several musculoskeletal disorders of the hand and shoulder that can be debilitating (1,2). Limited joint mobility, also termed diabetic hand syndrome or cheiropathy (3), is characterized by skin thickening over the dorsum of the hands and restricted mobility of multiple joints. While this syndrome is painless and usually not disabling (2,4), other musculoskeletal problems occur with increased frequency in diabetic patients, including Dupuytren’s disease, carpal tunnel syndrome, palmar flexor tenosynovitis or trigger finger, and adhesive capsulitis of the shoulder (5–10). The association of adhesive capsulitis with pain, swelling, dystrophic skin, and vasomotor instability of the hand constitutes the “shoulder-hand syndrome,” a rare but potentially disabling manifestation of diabetes (1,2). Most previous studies of the association between diabetes and musculoskeletal syndrome have not included a control group (5,7,8,11–15) or differentiated between type 1 and type 2 diabetes (9,11,16), or included only a single musculoskeletal syndrome (4,7,9,13,14,16). We report the epidemiology of adhesive capsulitis, carpal tunnel syndrome, Dupuytren’s disease, and flexor tenosynovitis in 100 patients with type 1 diabetes and 100 patients with type 2 diabetes, as well as in 100 control patients.
