You may know it by several terms . . .
. . . but if you are a patient in need of an ankle fusion, you should know that not all arthrodesis nails are the same. Compression of a fusion site is critical in ensuring joint stability and promoting bone union. However, many fusion system designs are highly susceptible to a loss of compression or loosening. They potentially loose up to 90% of their compression when the bone is reforming itself after surgery. This can result in arthrodesis failure (or nonunion) and it’s attendant complications.
DynaNail® adapts to these post-operative changes in bone structure. DynaNail® maintains compression better than these other nails, and it reduces the risk of complications.
The DynaNail® TTC Fusion System is designed for foot and ankle fusion procedures to address degenerative conditions, correct joint deformities, and revise failed total ankle replacements. The groundbreaking nail system incorporates an innovative super-elastic internal nickel titanium element. This element automatically adapts in response to changes in bone and joint structure after surgery.
Contact us today for more information on DynaNail®. We’ll also connect you with a physician in your area who will work with you to identify and alleviate your foot and ankle pain. We are associated with a network of doctors in the State of Florida who can determine the correct course of treatment and whether the MedShape DynaNail® TTC Fusion System is right for you.

"This is one case that really illustrates the power of the DynaNail in terms of reconstruction for patients in difficult clinical scenarios. The ability of the nail to adapt post-operatively as the anatomy changes and the bone shifts is unparalleled by any other implant on the market."
"I have implanted many DynaNail devices and have been impressed with my patient outcomes to date. DynaNail gives me the confidence that even my most complex patients will receive the compression needed to achieve successful fusion."
"Continuous compression has made a big difference with fusing joints in high risk patients. While compression and stability can be lost with a static nail, Dynanail keeps the joints stable for the duration of bone healing, even in those slow-healing patients."
"I am excited to have the DynaNail XL available as an option for my TTC fusion surgeries. The variability in size without changing technique or set up in the operating room expands this product's utility. Now with the variable length offerings, I can apply this unique technology to more of my patient population including those with post-traumatic deformity, previous hardware stress risers, and individuals with a larger frame where increasing the working length of the device likely improves stability."
"The DynaNail, with its dynamic compression NiTiNOL technology, has greatly changed the way I treat my patients. Not only are my patients achieving successful fusion when prior fusion surgeries had failed, but their quality of life is greatly improved."
Hindfoot fusion nails have evolved in conjunction with the increasing knowledge of factors that lead to successful fusion. This evolution is driven by the need for a simple and robust application of compression across the joints and exemplified by several generations of intramedullary nails in clinical use.
Early 1st generation hindfoot fusion nails offered no means of applying compression but rather served to statically lock the nail into the bone with screws.
2nd generation nails allow for external manual compression to be applied using compression rods through the frame. Studies have shown that this form of intramedullary nail fixation results in loss of compression upon removal of installation frame.1
Internal compression was introduced with 3rd generation IM nails using an internal screw to press against a talar or calcaneal screw. While able to retain compression after instrument removal, these nails lose compression in the presence of bone resorption.
Utilizing the superelastic properties of NiTiNOL, the DynaNailrepresents the NEXT generation of intramedullary nail fixation by maintaining compression after surgery for up to 6 mm of bone resorption or settling. In addition like older generation intramedullary nails, 6 mm of manual compression can still be applied during surgery.
