1 Preoperative planning Complete a preoperative radiographic assessment, to confirm the presence of sufficient bone stock for the four-corner fusion procedure, and intact joint surfaces between the radius and the lunate. Determine the angle of the extension deformity of the lunate. 2 Position patient Position the patient supine, with the forearm positioned on a hand table in full pronation. Use a rolled towel to support the palm of the hand. The use of a tourniquet and magnifying loops is recommended. 2.4 mm Variable Angle Locking Intercarpal Fusion System  Surgical Technique  DePuy Synthes

1 Approach Make a standard dorsal longitudinal approach to the wrist. 2 Excise scaphoid and debride midcarpal joint Completely excise the scaphoid and debride the midcarpal joint. Use a small rongeur and/or chisel to remove the residual cartilage. Ensure that sclerotic and dense subchondral bone is removed down to cancellous bone. Complete debridement of the midcarpal joint is mandatory. Preparation of the joint surfaces between the capitatum/ hamatum and lunatum/triquetrum is optional, or may be carried out after provisional fixation. Note: Proper removal of the cartilage to cancellous bone...

3 Reduce rotational deformity and provisionally fix carpus Instrument 02.111.304.10 1.25 mm Kirschner Wire, with trocar tip, 80 mm If necessary, use a Kirschner wire as a joystick in the lunate to correct the position of the lunate. Temporarily fix the lunate in the neutral position with a Kirschner wire from distal through the capitate and remove the joystick K-wire. Intraoperatively check residual mobility. In general, more extension than flexion is recommended. Notes: – Verify correct alignment with radiographic imaging. – If performing reaming technique without the reaming guide, ensure K-wire...

1 Position reaming guide Instruments 02.111.304.10 1.25 mm Kirschner Wire, with trocar tip, 80 mm Reaming Guide, for 2.4 mm VA Locking Intercarpal Fusion Plate, 15 mm Reaming Guide, for 2.4 mm VA Locking Intercarpal Fusion Plate, 17 mm Choose the appropriate reaming guide (15 mm or 17 mm) according to the selected plate, and fix it temporarily, with at least one Kirschner wire per carpal bone, over the center of the four-bone junction. If necessary, remove the volar lunocapitate Kirschner wire, to avoid later interference with the reamer. Note: The shape of the reaming guide is adapted to the...
