Frequently surgical amputation of a lower extremity is required when gangrene develops as a result of peripheral vascular disease. This is particularly true in geriatric patients. A below-knee amputation, with refinements in the surgical procedure, and immediate rigid-cast prosthetic fitting are strongly advocated by our group. The progress of two patients treated in this manner is described. Preservation of the knee joint improves the amputee's prognosis for ambulation with a below-knee prosthesis. The rigid-cast dressing on the below-knee amputation reduces edema and postoperative pain, is of psychologic value to the patient, and permits him to stand at from one to two days postoperatively.
当因外周血管疾病发生坏疽时，常常需要对下肢进行手术截肢。老年患者尤其如此。我们小组强烈主张进行膝下截肢，并改进手术操作，同时术后立即安装硬模假肢。本文描述了两名接受这种治疗方式的患者的进展情况。保留膝关节可改善截肢者使用膝下假肢行走的预后。膝下截肢后的硬模敷料可减轻水肿和术后疼痛，对患者具有心理价值，并使患者能够在术后一到两天站立。
