Above knee amputee

Specialties Orthopaedic


I have a question . Last year I took care of a few amputee pt. I am going into my second yr of nursing school. Well what I want to know is with AKA, what happens to the muscle insertion at the knee? Do they have any hip flexion, do muscle contractures happen. BKA is preferred if possible I would suppose. Any input would be great, I have thought about this from time to time.Janice


Yes they do have flexion at the hip. Many times too much! If they begin to develop hip flexion contracture many times the surgeon will order a certain number of hours lying prone to prevent them. If the AKA is a one stage...then the muscles are wrapped around the end and the skin is closed. The docs usually order a stump shrinker to make the end of the amputation bullet shaped instead of flat on the end. The shrinker helps prepare the stump for future prosthesis use.

A two stage surgery would be if it were left open....as in traumatic amputation I&D and then closed at a future time. These are usually pretty bloody!
