DYNANAIL® TTC FUSION SYSTEM

The DynaNail® TTC Fusion System is designed for use in tibiotalocalcaneal (TTC) fusion procedures to address degenerative conditions, correct joint deformities and revise failed total ankle replacements or arthrodesis non-unions.

The DynaNail incorporates MedShape’s patented superelastic nickel titanium (NiTiNOL) technology that can respond and adapt to changes in the joints. Intra-operatively, the NiTiNOL Compressive Element is stretched into its activated state and fixed with screws. Post-surgery, the Compressive Element will maintain the target fusion bones in close apposition and under compression for up to 6 mm of bone resorption or settling.

Maintained Compression Without External Fixation? Nailed It

The DynaNail® TTC Fusion System is the ONLY fusion approach that offers the compression performance of an external fixator inside an intramedullary nail.

  • Achieves 6 mm of post-operative compression PLUS 6 mm of intra-operative manual compression
  • Provides automatic dynamization upon weightbearing
  • Accompanied by the robust DynaFrame™ CF (Carbon Fiber) Deployment System
  • Available in multiple diameters and lengths – NEW! Now offered in 260 and 300 mm lengths for revision and bail out procedures

Demonstrated Elite Performance

The Proof Is In The Science

Maintained Active Compression
Benchtop testing shows that the DynaNail can maintain compression for up to 6 mm of bone resorption or settling similar to an external fixator. In contrast, existing static IM nails lose 90% of their compression when just 1 mm of bone resorption occurs.

Immediate Dynamization
Thanks to the axial compliance of its NiTiNOL Compressive Element, DynaNail is able to transfer almost 70% of forces to the bone during weight-bearing; whereas, static competitor nails are only able to transfer 20% of walking forces.
