Stabilis™ Ankle Arthrodesis Plating System

The Stabilis Ankle Arthrodesis Plating System advances ankle fusion surgery through reproducible joint preparation and anatomic construct rigidity. The Tornier Stabilis Ankle Arthrodesis Plating System is a first for the ankle surgeon:

  • First to include three fusion plating options in one system: a lateral TT, a lateral TTC, and an anterior fusion plate
  • First to offer instruments in the set specifically aimed at making joint preparation easier and more reproducible
  • First to incorporate the best of locking and non-locking plate designs in the unique and patent-pending CoverLoc® system
Stabilis™ Ankle Arthrodesis Plating System

Features & Benefits

 

The CoverLoc Advantage

Headless screws that allow good plate to bone interface and locking sheaths to provide the fixed angle rigidity required for a solid fusion.

The Lag Effect:

Without the conventional locking threaded-head screws, CoverLoc screws still allow the plate to be pulled to the bone minimizing plate standoff and strengthening the overall construct, promoting better fusion.

Locking Mechanism and Soft Tissue Protection:

The CoverLoc sheaths are locked to the plate and prevent screw back-out. The sheath’s smooth surface reduces the possible soft tissue irritation sometimes caused by screw heads.

Fixed Angle Support:

The CoverLoc sheaths rigidly hold the screw angles, creating a locking mechanism without threaded-head screws.

Anatomic Screw Placement Maximizes Bone Purchase:

The screw paths are designed to avoid the joint lines. The screws are at divergent angles to prevent motion and enhance fusion. Once the joint is compressed with the Joint Compressors, the plate holds the full construct in place and promotes joint fusion.

Stabilis Plates and Screws

Anterior Tibio-Talar Plate

  • Anterior surgical approach preserves the fibula and leaves the lateral gutter untouched
  • Procedure choice allows for conversion to ankle arthroplasty at a later stage if applicable
  • Excellent mechanical resistance to bending motion of the ankle joint (plantar and dorsi flexion)
  • Better compression and more stable than screws alone1
  • Smooth, anatomic, low profile plate limits possible tendon irritation and does not interfere with wound closure
  • Non-locking proximal screws lag the plate to the bone
  • 2 plate options accommodate di!erent natural talar neck anatomies:
    • 107.5° distally angled portion against the talar neck
    • 95° distally angled portion against the talar neck
  • Universal Left/Right size

Lateral Tibio-Talar Plate

  • Lateral cutting guides facilitate enhanced joint preparation
  • Lateral approach offers good visualization of the joint during preparation
  • Better mechanical resistance to bending motion of the ankle joint (plantar and dorsiflexion) than screws alone1
  • Better compression and more stable than screws alone1
  • Smooth, anatomic, low profile plate limits possible tendon irritation and does not interfere with wound closure
  • Non-locking proximal screws lag the plate to the bone
  • 2 plate options accommodate di!erent natural lateral talar anatomies:
    • 15° distally angled portion against the talus
    • 30° distally angled portion against the talus
  • Universal Left/Right size

Lateral Tibio-Talo-Calcaneal Plate

  • Lateral cutting guides facilitate enhanced joint preparation
  • Better mechanical resistance to bending motion of the ankle joint (plantar and dorsiflexion) than screws alone1
  • Better compression and more stable than screws alone1
  • Locking plate offers better rigidity than IM nail1
  • Smooth, anatomic, low profile plate limits possible tendon irritation and does not interfere with wound closure
  • Non-locking proximal screws lag the plate to the bone
  • Universal Left/Right size



Anatomic shape accommodates natural talus and calcaneus profile

Indications

The Stabilis Ankle Arthrodesis Plating System is intended for arthrodesis of the ankle joint and distal tibia, fractures, osteotomies, and fusions of small bones including the foot and ankle. Prior to using any Tornier device, please review the instructions for use and surgical technique for a complete listing of indications, contraindications, warnings, precautions, potential adverse events, and directions for use.
