This current concepts review from Walter Reed covers the operative principles and level-specific techniques for traumatic lower-extremity amputations. It addresses the limb salvage versus amputation decision, soft-tissue and nerve management, level selection, postoperative care, and common complications. It draws heavily on the LEAP study — the largest prospective study of severe lower-extremity trauma outcomes — to contextualize functional expectations.
The residual limb is a reconstructive challenge, not a surgical afterthought — yet amputation closures were historically delegated to the least experienced person in the room. This paper codifies why that is wrong: complication rates exceed 85%, nearly half of amputation wounds develop infection or necrosis, and a chronically painful stump is a predictable result of technical errors that are well-described and preventable.
When you perform or assist on a trauma amputation, three decisions define the outcome: level selection, myodesis, and nerve management. Preserve length when soft tissue allows (2.5 cm per 30 cm of patient height for transtibial), always perform myodesis over myoplasty alone, and pull every named nerve under traction before cutting to relocate the inevitable neuroma away from the prosthetic socket contact zone.
For transfemoral cases specifically: adductor myodesis is not optional. Loss of the adductor magnus insertion eliminates 70% of the femoral adduction moment, and the resulting lateral drift creates a gait that no prosthesis can fully correct.
The LEAP data also change how you counsel patients: an insensate foot at presentation is not an indication for amputation (most recover plantar sensation by 2 years), and outcomes after amputation and limb salvage are equivalently poor in terms of disability — the conversation with the patient should reflect that neither path is easy.
