Amputation surgery and prostheses

Wide surgical margins in surgery for a bone tumor can be accomplished either by local excision or by amputation surgery. Amputation surgery has less morbidity than limb salvage surgery. Prosthetic replacement in the lower-extremity amputation should provide an artificial limb that will be comfortable and stable for weight bearing. Retention of the anatomic knee joint is critical for better ambulation and less energy expenditure. Upper-extremity prosthesis should be functional and cosmetically acceptable.
