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.
确定并随访了22例患有糖尿病且因上肢坏疽而需要截肢的患者，他们的平均年龄为51岁。在最近一次随访时仍在世的5例患者，平均随访了50.6个月。其他17例患者截肢后平均仅存活20.6个月。所有患者健康状况均较差；18例患者曾需要下肢截肢，16例接受血液透析。上肢截肢结果不理想；22例患者中仅2例的初次截肢部位愈合。在其余20例患者中，上肢总共又进行了63次手术，其中20例患者中有5例在伤口愈合前死亡。
