Treatment If the ulna is merely hypoplastic, treatment is not usually required. Occasionally, the fibrous band must be excised to prevent progression of the ulnar deviation of the wrist. In this operation it is important to spare the malformed ulnar vessels and nerves. The ulnar deviation can generally be pre- vented by splints, and the resection of the fibrocartilagi- nous structure is rarely required. Measures on the fingers are required if additional anomalies exist on the side of the 1st ray and the grasp function is impaired.
