Dorsal ligamentoplasty reinforced with an internal brace
After a longitudinal dorsal incision of the wrist, an ECRB (extensor carpi radialis brevis) or palmaris longus hemi-tendon is harvested. The scapholunate positioning is adjusted using joystick pins. A 2.5 mm blind tunnel is made in the lunate and two 2.5 mm blind tunnels are made in the proximal and distal poles of the scaphoid. The tendon graft is threaded using a fiberloop and reinforced with suture tape. The graft is fixed in the proximal pole of the scaphoid with a swive-lock anchor (Arthrex®), then in the lunate, and finally fixed in the distal pole of the scaphoid by the same method. An anti-rotation scapho-capitate pin is then placed. This is maintained for 6 weeks during post-operative immobilization with a wrist orthosis. Rehabilitation begins after the pin is removed.
