The VariAx 2 Distal Radius and VariAx 2 Distal Ulna Plating System is designed to provide you with a comprehensive range of anatomic plating options that work with a common instrument and screw platform. Plates utilize SmartLock technology which permits polyaxial screw placement. You can angle locking screws up to 15˚ in each direction for a total range of 30˚ providing you with the flexibility to position screws based on the patient, not a plate’s pre-existing design.

SOMA® Designed
Only by truly understanding the challenges you face can we offer a portfolio to best fit your needs. With anatomically contoured plates designed or validated using our proprietary SOMA technology, streamlined instrumentation, and trained representatives, our plating portfolio is designed with you in mind.
Our plating portfolio ranges from indication specific plates and Smartlock technology to streamlined instrumentation for ease-of-use in the OR. Helping to solve complicated fractures with simple innovative solutions – Plating that fits.
Stryker Orthopaedic Modeling and Analytics, or SOMA, consists of a database of over 40,000 3D bones generated from CT scans of patients2. This comprehensive database and proprietary software helps design a better fitting implant and allows for true evidence based design.
The VariAx 2 screws allow 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. The 2.0mm drill guide for T8 screws facilitates drilling a 2.0mm pilot hole for a 2.4 or 2.7mm T8 screw or a 2.0mm peg centrically for locking or non-locking screws.
XXL Plating Options:
There are sixteen additional plates in 74mm (5 hole), 100mm (8 hole), 145mm (11 hole) and 189mm (15 hole) lengths, standard and narrow widths, and in left and right anatomic shapes. These plates are pre-curved to fit the radial bow. The stronger plate design includes a smooth transition from 2 to 3mm at the meta-diaphyseal intersection of the plate. The pre-angled screw holes in the distal part of the plate and Z-shaped screw hole configuration in the shaft allow for additional flexibility in fracture fixation. The higher profile plate design allows for stronger fixation in osteotomies, mal-unions and non-unions.
