Amputation levels are somewhat standardized: Upper limb amputations include Partial hand: Digit, metacarpal-phalangeal, carpal-metacarpal Wrist disarticulation Transradial Elbow disarticulation Transhumeral Shoulder disarticulation and forequarter amputation Lower limb amputations include Partial foot: Ray resection, transmetatarsal Tarsometatarsal (Lisfranc) Transtarsal (Chopart) Transcalcaneal (Boyd) Ankle disarticulation Transtibial Knee disarticulation Transfemoral Hip disarticulation and hemipelvectomy Because different socket designs may benefit from slight changes in surgical technique, preoperative consultation between surgeon and prosthetist is useful.
