VariAx 2 Distal Radius Locking Plate System This publication sets forth detailed recommended procedures for using Stryker devices and instruments. It offers guidance that you should heed, but, as with any such technical guide, each surgeon must consider the particular needs of each patient and make appropriate adjustments when and as required. A workshop training is recommended prior to first surgery. All non-sterile devices must be cleaned and sterilized before use. Follow the instructions provided in our reprocessing guide (L24002000). Multi-component instruments must be disassembled for...

Indications, Precautions & Contraindications Intended Use The VariAx 2 Distal Radius Locking System including the XXL Volar Distal Radius Plates is intended for internal fixation of small bone fractures, primarily including distal radius fractures. The physician’s education, training and professional judgment must be relied upon to choose the most appropriate device and treatment. The following contraindications may be of a relative or absolute nature, and must be taken into account by the attending surgeon: • Any active or suspected latent infection or marked local inflammation in or about...

SmartLock1 Polyaxial / Compression Drill Guide Allows for ±15 degrees of angulation. A lip on the drill sleeve will engage and allow toggling in the hole. The range in which the drill guide toggles will create a 30-degree cone and every angle in this range will be a locking position. This may allow the surgeon to aim where the screw/ peg should be placed. Also, depending on the placement of the plate, there may be a need to angle a screw/peg out of the fracture line. Note: • hen drilling eccentrically, the W arrow marked on the compression side of the drill guide should be pointing towards...

Modular Handle VariAx 2 offers a modular handle system. This is composed of two handle grip sizes (medium and large) that can be interchanged with either a bi-directional ratcheting AO-Coupling insert or a standard AO-Coupling insert. Both handle sizes are equipped with a spin-cap to allow insertion using a twofinger technique. In order to disengage the insert from the handle, push down on the button on the distal part of the handle and pull the insert away from the handle. Note: The inserts must be removed from the handles before cleaning. The ratcheting insert can work in three modes:...

Operative Technique Anatomical Volar Plate 1. An incision is made approximately 5-8cm long just radial to the FCR tendon. If more exposure is necessary, the incision can be extended radially at 45 degrees along the wrist flexion creases. 2. The FCR tendon is retracted ulnarly and dissection is carried down through the floor of the FCR sheath. 7. Choose the appropriate implant according to patient anatomy and fracture pattern. or the use of K-Wires for temporary fixation may be helpful. The use of AP/Lateral fluoroscopy is helpful to determine correct fracture reduction and plate position....

Operative Technique Anatomical Volar Plate 12. non-locking screw is placed in A the oblong gliding hole but not completely tightened to allow adjustment of the plate in distal or proximal directions. 13. After confirmation of the correct positioning of the anatomic volar plate by use of fluoroscopy, tighten the first screw. 14. nce the position of the plate has O been determined, it is time to decide which drill guide to use based upon preference and/or fracture pattern. 15. sing the desired drill guide, repeat U drilling, measuring and placement of screws/pegs in the distal holes. 17....

Operative Technique Universal Volar Plate 1. An incision is made approximately 5-8cm long directly over the FCR tendon. If more exposure is necessary, the incision can be extended radially at 45 degrees along the wrist flexion creases. 2. The FCR tendon is retracted ulnarly and dissection is carried down through the floor of the FCR sheath. 7. The plate should be placed slightly below the distal edge of the distal radius to avoid inserting screws or pegs into the joint. The use of AP/Lat fluoroscopy is helpful to determine correct fracture reduction and plate position. external traction,...

Operative Technique Universal Volar Plate 12. fter confirmation of the correct A positioning of the volar plate by use of fluoroscopy, tighten the first screw. 13. Repeat drilling, measuring and placing of screws/pegs in the distal holes of the plate. The position and number of screws applied depends on the type of fracture. 14. Place Non-Locking or Locking screws in the proximal end of the plate. 15. erify proper placement of screws and pegs by use of fluoroscopy to ensure V that neither penetrates the joint. 16. Close the incision. Note: The tips of the screws in the distal holes should...

Operative Technique Dorsal Plate 1. Longitudinal incision is made just ulnar to Lister’s tubercle at the distal radius region. 2. Dissection is performed down to the extensor retinaculum. The third compartment is opened and the extensor pollicis longus is displaced radially. 3. The second compartment wrist extensors are subperiosteally elevated radially and the fourth compartment is subperiosteally elevated ulnarly. The terminal branches of the posterior interosseous nerve may be excised for pain reduction. an external traction device and/or K-Wires for temporary fixation may be helpful. 6....
