Supracondylar amputation in the aged.

Of 105 consecutive supracondylar amputations done at the San Diego County General Hospital during the five-year period, 1953-58, 88 were in patients more than 60 years of age. Occlusive arterial disease was the reason for operation in 85 of the 88 cases. Presenting complaints at the time of amputation were gangrene in 45 cases, pre-gangrene associated with severe pain in 34. Acute arterial occlusion as a cause of thigh amputation was infrequent. The average age of patients requiring thigh amputation from complications of arteriosclerosis obliterans was 78.3 years; for those with diabetic arteriosclerosis or embolism it was about seven and a half years less. Supracondylar amputation was considered the procedure of choice in the elderly debilitated patients with far-advanced occlusive diffuse arteriosclerosis, complicated by gangrene, ulcer and infection of the toes or feet. Sympathectomy and direct arterial operation if done early in the course of the disease may postpone or prevent subsequent amputation. The surgical mortality rate (first two weeks) for supracondylar amputation was 12.5 per cent. More than two-thirds of the deaths were due to bronchopneumonia.
