Treatment of trigger finger in patients with diabetes mellitus. 
We present a retrospective study of 54 diabetic patients with 121 trigger digits treated over a 3-year period by one to three injections of corticosteroid mixed with local anesthetic.  As a group, diabetic patients responded less favorably to treatment by steroid injection (50% symptom resolution) when compared to reported outcomes of steroid injection treatment for stenosing tenosynovitis in the general population.  Insulin-dependent diabetic patients have a higher incidence of multiple digit involvement (59% of patients) and of requiring surgical release for relief of symptoms (56% of digits) when compared to non-insulin-dependent diabetic patients (28% of patients with multiple digit involvement; 28% of digits requiring surgery).
