Gangrene of the upper extremity in diabetic patients.

Twenty-two patients who had diabetes mellitus and had needed an amputation for gangrene in an upper extremity at an average age of fifty-one years were identified and followed. The five patients who were still living at the latest follow-up had been followed for an average of 50.6 months. The other seventeen patients survived for an average of only 20.6 months after the amputation. All of the patients were in poor health; eighteen had needed an amputation in a lower extremity, and sixteen received hemodialysis. The results of amputation in an upper extremity were unsatisfactory; the site of the initial amputation healed in only two of the twenty-two patients. In the remaining twenty patients, a total of sixty-three additional operations were performed on an upper extremity, and five of the twenty patients died before the wound had healed.

Comparative analysis of ankle arthroplasty versus ankle arthrodesis.

In a retrospective study of 41 patients with total ankle arthroplasty (25 patients) and ankle arthrodesis (18 patients), the mean follow-up period was 3.8 years for total ankle arthroplasties and 3.3 for ankle arthrodeses. Sixteen of the 23 ankle arthroplasty patients, and 17 of the 18 arthrodesis patients had good or excellent results. Total ankle arthroplasty was successful in patients with rheumatoid arthritis, but not posttraumatic arthrosis. Total ankle arthroplasty is indicated in rheumatoid patients with severe ankle involvement who have not responded to medical management. It also may be used in the elderly or debilitated patients who will place minimal stress on the ankle. The elderly may not tolerate the prolonged immobilization or repeated operations that fusion may require. Total ankle arthroplasty should not be used in young patients with posttraumatic arthrosis.

Analysis of six hundred and twenty-two intertrochanteric hip fractures.

Of 622 intertrochanteric fractures, 57% were stable (Types I and II). Twenty-eight per cent were Type III, and 15% were Type IV (the unstable types). The 150-degree telescoping Massie nail proved superior to the fixed 135-degree Jewett nail (particularly for unstable fractures) because it allowed a controlled impaction of the fracture fragments to a stable position. In about one-third of the fractures, some medial displacement occurred. With anatomical reduction and the use of the Massie or ASIF nails, we achieved a decrease in the morbidity and mortality and 96% satisfactory results. Our prospective study was compared with a retrospective study in which other devices were used. Early ambulation and weight-bearing also was a major contributing factor to the improved results in the prospective study. Intertrochanteric hip fractures that are unstable can be fixed with a collapsible nail, and that treatment appears to give as good or better results than the displacement method of Dimon and Hughston or Sarmiento.
