A Feasibility Trial of a Prefabricated Immediate Postoperative Prosthetic Limb System

In this feasibility trial, 32 consecutive patients undergoing transtibial or knee disarticulation amputation had application of a prefabricated immediate postoperative prosthesis in the operating room following lower extremity amputation. Partial weightbearing was initiated on the first postoperative day. Twenty-nine underwent primary amputation as a consequence of nonsalvageable gangrene or diabetic foot infection. Others were performed at the time of wound closure following traumatic amputation for a crushed extremity and one was performed for an infected nonunion of the tibia and fibula. Seventeen of the 29 patients with diabetes were insulin dependent. Nine patients required renal dialysis and were diagnosed with concurrent malnutrition. Twenty were male and 12 were female, with an average age of 61.6 (range, 42–90) years. The average time to custom prosthetic limb fitting was 8.1 (range, 4–16) weeks. This preliminary experience with a commercially available pneumatic immediate postoperative prosthetic limb system supports its role in the early rehabilitation of lower extremity amputees.
