title: Transmetatarsal amputation.
abstract: We have reviewed the records of 25 patients who underwent a transmetatarsal amputation at San Francisco General Hospital. The average patient age was 63 years old. Twelve of the patients were diabetic, while transmetatarsal amputations were performed in eleven with simple arteriosclerosis. Two patients underwent amputations for either trauma or nonhealing ulcer. Thirteen of the patients healed their amputation, and twelve of these became ambulatory. Eleven required higher amputation, because of nonhealing due to infection in seven and progressive ischemia in four. One patient died on the first postoperative day of pneumonia. The failure group was younger, contained more diabetics, and had a higher incidence of infection. The operative procedure of transmetatarsal amputation is described. We believe that patients with distal gangrene without spreading infection should be considered for transmetatarsal amputation, reserving initial below-knee amputation for those with greater involvement of the foot.
