Twenty-four hands in twenty-three patients in the Stroke Service at Rancho Los Amigos Hospital had a superficialis and profundus release procedure with transfer of the proximal ends of the superficialis to the distal ends of the profunds for severe pronation flexion deformities in the forearm and hand. The initial goal of improved position in the hand and wrist was achieved in twenty-one of the twenty-four patients operated on. In three patients who demonstrated volitional flexor control prior to surgery, that control was maintained after the operation.
