PediatrOS™ RigidTack™

Compensation of leg length differences

Since their introduction in 2015, PediatrOS™ RigidTack™ Epiphysiodesis Implants have enjoyed an unbroken track record of success in compensating leg-length differences, making them a genuine alternative to implants approved for conventional applications.

The trapezoidal design of the PediatrOS™ RigidTack™ staple is closely aligned to the anatomy of the femur and tibia. Cannulated legs allow precise placement using Kirschner wires. PediatrOS™ RigidTack™ staple implants for growth control via temporary epiphysiodesis have rigid central zones designed to withstand the growth forces exerted by the epiphyseal plates.

Properties / technical data

  • First anatomically shaped titanium implant designed to correct leg length differences
  • Minimally invasive surgical technique keeps sedation time short
  • Low fluoroscopy times – 35% reduction over plate systems
  • Parallel insertion of two 1.6 mm K-wires through cannulated implant legs allows precise placement
  • Trapezoidal design provides ideal biomechanical orientation
  • Allows immediate weight-bearing
  • Zigzagged leg shape prevents implant migration
  • PediatrOS™ FlexTack™ corrects misalignments; PediatrOS™ RigidTack™ corrects leg length differences
  • Material: TiAI6V4 ELI
  • Available in 3 sizes: 20 mm (blue), 25 mm (green), 30 mm (purple)
