The new toe implant gets its 'memory' from a revolutionary alloy called NiTinol, which has unique compressive - or shape memory - properties that are activated by body heat. Inserted after being cooled by the surgical team, the implant expands in width, securing it in place, then gradually shortens in length, creating compression across the joint line. The expansion and shortening processes encourage joint fusion and healing. The implant is also available in a different design that is super-elastic, with a spring-like action that does not require heat or cold to function.
In addition to the material's unique properties, the one-piece design of both types of Smart Toe implant bring advantages. Other implants commonly used to correct hammertoes are two pieces that must be connected during surgery, risking disconnection and rotation afterward. Rotation is also a frequent problem with K-wire stabilization that can result in improper fusion. Because the Smart Toe implant is completely internal, it resists any movement or rotation and can be positioned where needed without disrupting otherwise healthy bone.
Patients See Better Results
Leading experts around the country specializing in foot care have been using the Smart Toe implant with notable success. "I was looking for a better method for fusing the toe joints - one that would allow for stability without the use of external wires," says Stuart Mogul, DPM, FACFAS, of Mogul FootCare (www.mogulcare.com) in New York City. "To date, patient satisfaction has been high."
