Prostheses, Upper Limb, Wrist Component, Electrical
Definition : Wrist prostheses operated by electric power and designed for partial functional (e.g., rotation, flexion) replacement of the wrist above the wrist articulation. These prostheses typically consist of external devices with a metal ring-shaped mechanism that can provide rotational and flexion movements and locking positions at the distal end to a terminal device (e.g., hand, hook); they can be attached at the proximal end with a socket to the residual limb or to another prosthetic device (i.e., forearm replacement). Electrically powered wrist prostheses incorporate small electrical motors and manual electrical switches to control the wrist and/or terminal prosthesis movements. They are typically used as a 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.
