VariAxDistal Radius Locking Plate System - Stryker

IntroductionThe VariAx Distal Radius PlatingSystem represents the Next Generationof Bone Fixation for your Distal RadiusFracture Needs.Intended UseThe VariAx Distal Radius LockingSystem incl. the XXL Volar DistalRadius Plates is intended for use ininternal fixations of the small bonefractures, primarily including distalradius fractures.IndicationsCompression fractures, intraarticularand extra-articular fractures,displaced fractures. Followingadditional indications apply only forthe XXL Volar Distal Radius Plates:Osteotomies, non-unions and malunions.Contraindications• Inadequate bone quantity and quality• Patients with active infections.• Patients with metal allergies andforeign body sensitivity.• Severely non-compliant patients withmental or neurological conditionswho are unwilling or incapableof following postoperative careinstructions.• Patients with limited blood supplyor insufficient quality or quantity ofbone.• Patients with unstable physical and/or mental health conditionsPrecautionsThe VariAx Distal Radius Plate Systemhas not been evaluated for safety andcompatibility in the MR environment.The VariAx Distal Radius Plate Systemhas not been tested for heating ormigration in the MR environment.System Features• Comprehensive Plating SystemProviding Anatomical Volarand Dorsal, Universal Volar andFragment Specific Solutions.• XXL Anatomical Volar PlatesExtra long volar plates are neededfor cases where the metaphysealcomminution extends to the radialshaft, they follow the curvature ofthe bone as it extends toward theproximal end of the radius. 4 lenghts,right, left, standard and narrowplates are offered.• Fixed Angle Drill GuideAssures placement of screws & pegsin a pre-determined angle.• Polyaxial Drill GuideAllows locking with an additionalangulation of ±15 degrees in any holeon the plate, except the oblong holein the shaft.• Anatomical Volar PlateEncourages articular support withLocking screws & pegs, providesbuttressing to the volar lunate facetand stable fixation of radial styloidfragments with two screws.• Full range of 2.0mm to 2.7mm Lockingand Non-Locking screws & pegsOffering intraoperative solutionsfor different fracture fixationrequirements.• Anodization Type II*Increases the strength of all VariAxDistal Radius Locking Plates andreduces the incidence of tissueadherence.T7 Drive and Cross-PinScrew Head DesignsBoth screw head designs allow axialstability, friction fit screw retention,and easy screw pick up from screwrack.SmartLock** Locking Technology• Patented SmartLock LockingTechnologyEncourages “locked” screw to plateinterface due to combination ofGrade II - Ti Plates and Grade V - TiScrews & Pegs.• SmartLock Locking Screws & PegsDesigned with threads on theunderside of the screw head, whichupon insertion engage the circular“lip” within any hole on the plate,except the oblong hole in the shaft.• One-step LockingIs achieved by simply inserting aLocking Screw or Peg within thepolyaxial locking range of±15 degrees, without the need forfurther steps.* Baumann A., Zander, N. “Ti6A14V with Anodization Type II: Biological and Biomechanical Effects”, March 2005.** The SmartLock Technology is patented (US 6, 322, 562; DE 43 43 117) by Professor Dietmar Wolter, Hamburg, Germany.4-15° +15°This operative technique was developedwith Richard Rogachefsky, MD.
