The use of protective digit prostheses in management of microangiopathy of fingers

Small artery occlusive disease (microangiopathy) of the palm and digital arteries may produce ischemia with painful ulcerations on the digits. These ulcerations may contribute to secondary infection and severe intolerance to thermal changes. The use of gauze wrappings to minimize ulceration has been tried; however, it is unhygienic and unsightly. A custom-made digit prosthesis is constructed with medical grade silicone over an artificial finger nail to provide positive seating of the prosthesis. The digit prosthesis is hygienic, esthetically acceptable to the patient and greatly protects ulcerated finger tips. (J Prosthet Dent 1999;82:246-8.)
