The DynaNail® TTC Fusion System is designed for tibiotalocalcaneal (TTC) arthrodesis procedures to address degenerative conditions, correct joint deformities and revise failed total ankle replacements or arthrodesis non-unions. The intramedullary nail system incorporates an innovative super-elastic internal nickel titanium (NiTiNOL) element that automatically adapts in response to bone resorption or joint settling. Once the nail is fixed in place with screws, the NiTiNOL element maintains the target fusion bones in close apposition and under sustained compression for up to 6 mm of resorption or settling, unlike static, non-adaptive intramedullary devices that lose compression immediately upon frame removal or initial resorption. This natural compression adjustment provides the DynaNail TTC Fusion System with the fusion power of an external fixator while still having the ease and safety of an intramedullary nail. Surgeons implant the DynaNail TTC Fusion System using a surgical technique similar to that of traditional intramedullary nails, thereby dramatically reducing the learning curve required for the new technology.
DynaNail® TTC Fusion System features:
- Titanium outer body
- Simple mechanical activation of the super-elastic internal NiTiNOL element
- Rigid, radiolucent, dual-arm targeting frame
- Large range of titanium locking screw sizes
The DynaNail® TTC Fusion System has been cleared by the United States Food and Drug Administration for sales in the United States. Protected by U.S. Patent No. 7,985,222. Other U.S. and International Patents Pending.
