FREEFIX® Ulnar Shortening System

The freedom to perform a distal or proximal osteotomy based on clinical need

Shortening options to address specific pathology

 

Distal Osteotomy

Metaphyseal location facilitates healing and maintains normal distal interosseous ligament tension

Proximal Osteotomy

Increases tension on distal interosseous ligament to enhance DRUJ stability

Plate features

Plate Features Distal
  1. Anatomic head and neck for ideal distal placement
  2. PROTEAN® bending feature to adjust neck angle
  3. Laser marking every 2mm to set osteotomy length
  4. Guide rails to secure cutting guide
  5. Undercuts for saw blade clearance
  6. Plate notch for compression forceps
  7. FREEFIX® slots accommodate both compression and locking screws at any position within the slot

  3. Guide rails to secure cutting guide
  4. Plate notch for compression forceps
  5. Oblique screw can be lagged using the AO principles of internal fixation
  6. FREEFIX® slots accommodate both compression and locking screws at any position within the slot

Distal and proximal cutting guides allow blade access from either side of the plate

Streamlined procedure that maintains rotational stability

Apply the plate to the bone with the proximal screws in the most proximal slot position.

Apply the plate to the bone with the proximal screws in the most proximal slot position.

Slide the cutting guide to the most distal position and secure with a k-wire(s). Perform the first cut.

Slide the cutting guide to the most distal position and secure with a k-wire(s). Perform the first cut.

Slide the cutting guide proximally to the desired shortening length and resecure with a k-wire(s). Perform the second cut and remove the cutting guide.

Slide the cutting guide proximally to the desired shortening length and resecure with a k-wire(s). Perform the second cut and remove the cutting guide.

Remove the bone wedge, loosen the slot screws and compress the fragments using the compression forceps.

Remove the bone wedge, loosen the slot screws and compress the fragments using the compression forceps.

Retighten the most distal slot screw while maintaining compression with the forceps.

Retighten the most distal slot screw while maintaining compression with the forceps.

Remove the compression forceps, retighten the proximal slot screw and place the final screw in the most proximal hole.
