Flexor tendon ruptures secondary to hamate hook fractures.
Four patients with flexor tendon ruptures secondary to hook of the hamate fracture are described. None of the patients had the diagnosis of fracture made before tendon rupture. All patients were treated with excision of the fractured hook and tendon repair. The tendon repair was usually an end-to-side (Y junction) of the profundus of the small to the profundus of the ring finger. After operation, all patients were free of pain and returned to their preinjury activity levels, but most had some limitation of motion in the digit with the tendon repair. The complication of tendon rupture not uncommonly follows basilar hook of the hamate fractures. Treatment by excision of the fracture and end-to-side tendon repair produces satisfactory results. Range of motion after tendon repair seems to depend more on the patient's age and the amount of inflammation at the site of repair rather than on the method of tendon repair.
