Adaptation of an Upper-Extremity Prosthesis

CAROLE JACQUES, BSR, OT*** AND EUGENE BANZIGER, CP(C)Vancouver, British Columbia


A congenital amputee was first seen at 10 months of age with a diagnosis of Moebius Syndrome, left cranial stenosis and congenital amputations: right above-knee, right belowelbow, and left above-elbow. She was fitted with prostheses on the lower and left upper limbs. The above-elbow prosthesis has a passive elbow and 12P hook. A cable was added at 13 months. A major problem was the lack of reliability of hook opening, even when the limb was moved passively. At two years the child was still unable to open the hook. The elbow joint and forearm were removed and the wrist unit and hook attached directly to the end of the socket which was angled 90 degrees medially. After having this prosthesis for one day, the child could open the hook.
