Prosthetic usage following major lower extremity amputation.

There were 157 patients following major lower extremity amputation who were evaluated to determine functional prosthetic ambulation. Twenty-eight patients were evaluated in the amputee clinic and found not to be candidates for prosthetic fitting. Forty-one patients were fit with a prosthesis but did not become functional prosthetic ambulators. Eighty-eight patients became functional prosthetic ambulators. Of all above-the-knee amputees, 46% became functional prosthetic ambulators. Only 19% of bilateral lower extremity amputees became functional prosthetic ambulators. Of all below-the-knee amputees, 66% became functional ambulators. The presence of coronary artery disease decreased the ambulatory potential in above-the-knee or bilateral amputees but not in below-the-knee amputees. A screening method for elderly, dysvascular amputees should be instituted prior to prosthetic fitting.
