Myoelectric prosthesis: A potential emerging therapeutic in restoring function post-arm amputation complicated by necrotizing fasciitis

Abstract

A literature search confirmed no previous cases of an armamputation secondary to necrotizing fasciitis (NF) being successfully treated with amyoelectric prosthesis. This report explores a case of a 55-year-old right-handedmale with f lexor tenosynovitis infection of the hand after a small laceration. Following infectious disease consult of the infection, a diagnosis of NFwasmade. Broad-spectrum antibiotics were initiated but the infection worsened after 12 hours. Two debridements with wound vacuum were undertaken in the next 48 hours. After further patient deterioration, a distal left forearm amputation was undertaken. The patient fully recovered and then underwent occupational therapy training with a myoelectric prosthesis to restore hand function. The patient was seen for follow-up 3, 6, 12 and 24 months after amputation. At 2-year follow-up, the patient was continuing rehabilitation with an occupational therapist to acclimate to the prosthesis with some gain of function in gross movement.
