DynaNail® TTC Fusion System
DynaNail® TTC Fusion System
Sustained Dynamic Compression for TTC Fusions
The DynaNail® TTC Fusion System is engineered specifically for tibiotalocalcaneal (TTC) fusions, addressing degenerative conditions, joint deformities, and revision procedures with unique technology that adapts to the body throughout the healing process.
Powered by Enovis™ patented pseudoelastic NiTiNOL technology, the DynaNail® TTC Fusion System provides sustained, intraoperative and post-operative compression, optimizing biomechanical stability while promoting faster and stronger fusions. Unlike static implants that lose compression over time, DynaNail® continuously responds to bone resorption, reducing the risk of nonunion and enhancing long-term outcomes.

Overview
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.
- Delivers 6 mm of post-operative compression, plus an additional 6 mm of manual intra-operative compression
- Ensures automatic dynamization upon weight-bearing
- Paired with the durable DynaFrame™ CF (Carbon Fiber) Deployment System
- Available in a range of diameters and lengths, including 220 mm, 260 mm, and 300 mm for revision and bailout procedures
Demonstrated Elite Performance
The compression-sustaining DynaNail® TTC Fusion System is compatible with femoral head allografts, 3D-printed bulk spacers, and adjunctive fusion procedures like triple arthrodesis.

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, including other internal compression nails, lose 90% of their compression when just 1 mm of bone resorption occurs.1,2
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.3
