Amputation — Levels & Prosthetics

Level selection balances wound healing potential, prosthetic energy cost, and function. Upper limb: transmetacarpal, wrist disarticulation, trans‑radial, elbow disarticulation, trans‑humeral, shoulder disarticulation. Lower limb: Syme, transtibial (BKA), knee disarticulation, transfemoral (AKA), hip disarticulation/hemipelvectomy. Flap design: long posterior flap (BKA), myodesis over myoplasty for power and stability. Prosthetics: suspension (suction, pin‑lock), sockets (PTB, TSB), feet (SACH, dynamic response), knees (polycentric, microprocessor).
