Muscle Tear and Subsequent Muscle Infarction in a Patient With Uncontrolled Type 2 Diabetes Mellitus

Diabetes mellitus is associated with multiple microvascular and macrovascular complications. Musculoskeletal complications, such as diabetic muscle infarction, diabetic tendinopathy, Dupuytren contracture, cheiroarthropathy, and adhesive capsulitis, remain under-reported. Diabetic muscle infarction typically affects individuals with poorly controlled, long-standing diabetes and presents with sudden, nontraumatic muscle pain. Although some case reports exist on thigh muscle infarction and Achilles tendon tear in type 2 diabetes mellitus, upper limb involvement is extremely rare. We report such a case of a 65-year-old woman with diabetes who presented with a supraspinatus tear, subsequent diabetic muscle infarction, subscapularis and teres major myositis, and intramuscular hematoma, complicated by secondary infection and prolonged hospitalization.
