Prostheses, Upper Limb, Elbow Component, Mechanical
Definition : Elbow prostheses that are operated by mechanical power, usually supplied by other parts of the patient body (i.e., body-powered), and designed for partial functional (e.g., rotation, flexion) replacement of the elbow above the elbow articulation. These prostheses typically consist of external devices with a metal, hinged, yoke-like mechanism that can provide rotational and flexion movements and several locking positions; they can be attached at the proximal end with a socket to the residual limb (i.e., the humerus) or to another prosthetic device (e.g., a tube) and at the distal end to a tubular device (i.e., forearm replacement) that is, in turn, attached to a wrist prosthesis and a terminal device (e.g., hand, hook). Mechanical elbow prostheses may be externally or patient-actuated; in the most common configuration the elbow is operated by cables attached to a harness strapped around the shoulders. Elbow prostheses are available in a great variety of configurations and sizes; they are typically used as a component of an 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.
