Our Affiliate System

We are building one organization with affiliates in two regions. Our parent company, now known as Prisma Health, supports both affiliates with overall direction and leadership as we continue to align. We will soon share one brand across the entire organization to better reflect this. The rebranded Palmetto Health-USC Medical Group will continue to operate as a joint venture between the Midlands affiliate and the USC School of Medicine.

Upper Extremity Prosthetics

An upper extremity amputation can occur trans-radial (below the elbow) or trans-humeral (above the elbow).

There are two types of prosthetics for upper extremity amputations:

  1. Body powered – uses anatomical movements of the arms and shoulders to open or close the prosthetic hand
  2. Myoelectric – uses electrical signals (stimulus) a nerve sends to a muscle to open or close the hand

Other terms to know in reference to upper extremity prothesis:

  • Socket – what your limb will go into. It is a very important part of your prosthesis as it is what supports weight and aids in suspension. There are many different adjustments that can be made to ensure a comfortable fit inside the prosthesis.
  • Suspension – how the socket stays attached to your limb. This can be done via harnessing straps or using the contours of your arm to hold the socket in place.
  • Terminal device – This is at the end of the prosthesis and is used to interact with your environment. It can be a functional hook or hand terminal device. There are also non-functioning hand can be used for cosmetic purposes.
