title: Upper extremity infections in patients with diabetes mellitus.
abstract: Forty-five consecutive diabetic patients with 46 upper extremity infections who underwent surgical debridement were retrospectively reviewed. The infections involved the skin or subcutaneous tissue in 19 patients and the fascia, tendon, muscle, or bone in 27. Twenty-three infections (50%) required a single operation and 23 required more than 1. Eighteen infections (39%) required an amputation and there were 3 deaths directly related to an infection. Six of 7 infections in which anaerobic organisms were cultured culminated in amputation. Four patients were diagnosed with necrotizing fasciitis. Twenty-one cultures (46%) were polymicrobial. An increased rate of amputation was associated with deep infections below the subcutaneous tissue, renal failure, and infections with gram-negative, anaerobic, or polymicrobial cultures. An increased rate of repeat surgery and a prolonged hospitalization were associated with deep infection and polymicrobial infections.
