Prostheses, Upper Limb, Hook, Electrical
Definition : Hook prostheses operated by electric power and designed for partial functional replacement of a missing hand. These prostheses are typically external devices made of metal (e.g., cobalt-chromium alloys), hard plastics (e.g., polyethylene), carbon fibers, or a combination of materials; they are usually fixed with a socket to the wrist and require some degree of customization. Electrically powered hook prostheses incorporate small electrical motors and manual electrical switches to control the hook movements. They may be used alone as a replacement for a missing hand or as the terminal component of a below-the-elbow, above-the-elbow, or total upper limb prosthesis in patients who have congenital abnormalities or who suffered amputations due to illness (e.g., diabetes) or traumatic accidents.
