VariAx 2 Distal Ulna Locking Plate System

  • 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 
    • VariAx 2 Distal Ulna 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
  • Indications
    • The VariAx 2 Distal Ulnar System is indicated for the treatment of: 
      • Fractures
      • Non-unions
      • Malunions
      • Deformities
    • The DU Hook Plate may be used for DU fractures with a fractured or displaced ulnar styloid in order to apply compression on the fracture site
    • The DU Base Plate may be used for DU neck fractures and neck fractures that are extending into the shaft of the ulna
  • Approach
    • DU Hook Plates
      • A longitudinal incision is made over the palpable ulna
      • Expose the distal ulna in the region between the tendons of the flexor carpi ulnaris and extensor carpi ulnaris toward the ulnar styloid
      • Fracture fragments can be visualized
        and reduced. The fractured ulna styloid should be reduced and temporarily stabilized with a K-wire
    • DU Base Plates
      • A longitudinal incision is made over the palpable ulna
      • Expose the distal ulna in the region between the tendons of the flexor carpi ulnaris and extensor carpi ulnaris toward the ulnar styloid
      • Fracture fragments can be visualized and reduced
  • Placement
    • DU Hook Plates
      • The plate is slipped over the K-wire and placed along the medial aspect of the ulna, ensuring the distal hook is secured around the ulnar styloid
      • Plate placement can be adjusted by sliding the plate along the K-wire through the K-wire slot
    • DU Base Plates
      • Place the plate on the medial aspect of the ulna
      • Temporary plate fixation can be achieved by inserting a K-wire through the proximal K-wire hole or by placing an olive-stop K-wire through two of the screw holes
  • Specific Plates
    • Distal Ulna Hook Plate
      • SOMA designed
      • 1.5mm thickness
      • Distal hook allows for fragment reduction by K-wire prior to plate fixation and plate can be slid over K-wire for final reduction
    • Distal Ulna Base Plate
      • SOMA designed
      • 1.7mm thickness
      • Distal screw cluster offers more fixation options in a narrow footprint
  • 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
