Pair of CO2 gas powered prostheses for a Thalidomide affected child with complete absence of upper limbs (amelia). Valves are sited over both shoulders and activated by the acromion processes. Friction shoulder and elbow joints, for passive positioning. There is a powered right split-hook and wrist rotation unit and a passive left wrist unit with a powered split-hook. Elbow flexion is achieved by means of a perlon cord passing through a pulley and attached to a waist belt. Groin straps are necessary to prevent the belt from riding upwards in a very young child. Made by Steeper 1964. Detail, left shoulder. Grey background
