The Painful Diabetic Shoulder

Abstract

Different types of shoulder affection were studied in 62 diabetic patients with shoulder pain. Three groups of shoulder joint disorder were found: painful shoulder with restricted mobility (62%), tendinitis without mobility restriction (27%), and a small group with mixed diagnoses. Sixty percent had hand symptoms and 38% had restricted mobility of their hip joints. High frequencies of retinopathy and neuropathy were found. Affection of the shoulder joint was seen with almost the same frequency in insulin-dependent as in non-insulin-dependent patients, but after a shorter duration of diabetes in the latter. A group of patients with the triad shoulder pain, hand symptoms and restricted mobility of the hip joints had a significantly higher frequency of proliferative retinopathy than patients with shoulder pain only. The long duration of diabetes, the high frequency of insulin treatment and classical late complications indicate that diabetic patients with painful shoulder and restricted mobility are suffering from clinically advanced diabetes mellitus.
