Related Implants The VariAx® 2 series contain 3 plate types including VariAx 2 Compression Plating System VariAx 2 Distal Ulna Locking Plate System VariAx 2 Distal Radius Locking Plate System Design The VariAx 2 Distal Radius Plating System provides 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 Volar Distal Radius Plate Offerings Volar Distal Radius Plate Designed using Stryker Orthopaedics Modeling and Analytics (SOMA) database Distal taper around the watershed line Plate shape and thickness designed to reduce the potential for soft tissue irritation Functional window that allows fracture visualization, bone grafting and monoaxial locking Transverse hole is designed to allow for ulnar/radial plate adjustment Extended Volar Distal Radius Plate All the benefits of the Volar Distal Radius plate plus a more distal plate outline and screw pattern as well as a pre-bent extension for buttressing the volar-ulnar corner Tapered distal portion designed to reduce the risk of protrusion and soft tissue irritation around the watershed line Suture holes designed to allow for volar capsule tissue approximation with sutures XXS Distal Radius Plate Designed for a minimally invasive approach Available sterile only Dorsal and Fragment Specific Plates Standard Dorsal Plate SOMA designed 2mm thickness Styloid screw hole that can be bent if desired to patient’s need Low plate profile and flush screws to minimize soft tissue irritation Butressing of the complete dorsal rim Pre-angulated divergent screw trajectories distally Lateral Plate SOMA designed 2mm thickness Distal K-wire holes for paperclipping and additional small fragment fixation Dorsal Lateral Plate SOMA designed 2mm thickness, 0.75mm distal taper thickness Sits lateral to Lister’s Tubercle Distal K-Wire holes allow for additional small fragment fixation using paper-clip technique Dorsal Medial Plate SOMA designed 2mm thickness, 0.75mm distal taper thickness Sits medial to Lister’s Tubercle Distal K-Wire holes allow for additional small fragment fixation using paper-clip technique Volar Rim Plate SOMA designed 1.6mm thickness, 1.0mm distal taper thickness The vertical K-wire slots allow for distal or proximal adjustment and the horizontal K-wire slots allow for lateral or medial adjustment of the plate Sits on volar lip at the lunate facet Hooks to grab small distal fragments, which cannot be fixed with screws K-wire holes can be used for placing sutures in the volar capsule Wrist Spanning Plate SOMA designed 3mm thickness Offered in 2 lengths Clustered pairs of holes are designed to align with dorsal distal radius and bones of the carpus Tapered ends allow for easy plate sliding through ETC Specialized Instrumentation Plate Holding Reduction Clamp Designed to assist with fracture reduction and plate retention K-wire slots designed to aid with plate placement and distal K-wire fixation Aiming Block Comes pre-assembled with a set screw that attaches to plate through the distal threaded window hole Allows for drilling neutral axis of pre-angulated holes Threaded Drill Tower Fixed angle drill guide for all 2.4mm and 2.7mm screws Acts as a joystick to aid in plate positioning Indications The VariAx 2 Distal Radius System is indicated for the treatment of: Fractures Non-unions Malunions Deformities Approach Volar Plate/ Extended Volar Plate An incision is made approximately 5 – 8cm long just radial to the FCR tendon. DR Dorsal Plates Longitudinal incision is made just ulnar to Lister’s tubercle at the distal radius region Lateral DR Plates An incision is made along the radial column Dorsal Medial DR Plates When plate is being used in conjunction with the lateral plate, incision is made between the 4th and 5th extensor compartments Dorsal Lateral DR Plates Longitudinal incision is made just ulnar to Lister’s tubercle at the distal radius region Volar Rim DR Plates Incision is made through a standard volar Henry approach Alternatively, a direct medial approach may provide superior exposure For the direct medial approach, an extended carpal tunnel approach can be used distally and incorporated proximally to form an interval between the flexor tendons and the ulnar neurovascular bundle Placement Volar Plate/ Extended Volar Plate The plate should be placed slightly proximal to the distal edge of the radius to support the volar articular fracture fragment DR Dorsal Plates The plate should be placed slightly proximal the distal edge of the distal radius to avoid inserting screws/pegs into the joint Lateral DR Plates The brachioradialis can be elevated or the the plate can be placed directly on the brachiaradialis insertion Dorsal Medial DR Plates The plate is slipped over the K-wire and placed along the dorsal ulnar corner Dorsal Lateral DR Plates The plate is slipped over the K-wire and placed along the dorsal radial corner Volar Rim DR Plates The plate is slipped over the K-wire and placed above volar capsule on the volar ulnar corner Technical specifications Locking screws are laser marked with a ‘dot’ and ‘ring’ marking on the screw head to differentiate them from non-locking screws Locking and Non-Locking screws can be used in any round hole Allows for ±15 degrees of angulation 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 Screws 2.7mm Screws T8 Interface Locking & non-locking Purple 2.4mm Screws and 2.0mm Pegs T8 Interface Locking & non-locking Blue
