Correcting training errors and surgical management but there are a very few controlled equipment problems should also be accomplished. Imm- obilization results in deceased tendon strength and stiffness owing to proteolytic degradation of collagen (Hyman and Rodeo, 2000). Stretching and strengthening (particularly eccentric exercises) are thought to be beneficial but Almekinders LC, Temple JD: Etiology, diagnosis, and treatment there are few good studies that support this assertion.

The 1st metacarpal In the centralization procedure, the ulna is transferred is always hypoplastic.

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.
