Principles of Evaluation and Results in Microsurgical Treatment of Major Limb Amputations: A Follow-up Study of 26 Consecutive Cases 1978–1987

Abstract

A total of 26 microvascular extremity replantations/revascularizations with a survival rate of 85% were followed for an average of 4.5 years. The material consisted of 11 upper arms, 11 lower arms, 1 wrist and 3 feet. In this comparatively small and inhomogenous material there was no significant influence found on the functional results regarding level of amputation, time of ischaemia or age of the patients. Sharp injuries had the best outcome. The functional results were evaluated following the principles outlined by Chen & Yu and by Tamai. Good and excellent results were found in 63% of the upper extremities according to these classifications and in 47% according to our own classification. Some of the difficulties in establishing indications and contraindications to replantation are outlined. To facilitate comparison of materials a modified and more realistic version of the score system of Tamai is recommended as a standard for evaluation of functional results following above-wrist-replantation. This will enable early detection of progress in the treatment of extremity amputations.
