Also used to adjust the fit and comfort of the socket. The hip joint, knee unit, foot, and socket attach to this. The most important part of wearing a prosthesis is taking good care of the skin on your residual limb. This is done through daily inspection and washing with soap and water. If your prosthetist directs you to use prosthetic socks, use clean ones each day.
Fresh socks keep both the skin and socket clean.
Following these simple rules will eliminate most skin problems. You are still growing, and so is your residual limb. As this happens the socket may begin to fit poorly. If pain develops, it may be that the socket is outgrown. For some problems the socket can be adjusted but sometimes it means the prosthesis needs to be replaced.
