Smart Toe is a memory implant used in arthroplasty procedures to repair a toe hammer, claw leg and toe anomaly. Available in the US since 2007, the implant provides orthopedic and podiatric surgeons with new treatment options as it corrects the failure and implantation problems associated with K-wires and previous generations of implants, delivering very positive results with faster healing and multiple complications.

Pump Feet Surgery Option
The purpose of corrective surgery for the toe hammer is to straighten and align the injured toe, ensuring the bone is melted in the right position.
Different procedures for straightening your toes and allowing natural flexibility may involve cutting or aligning the tendon, rebalance the muscle, and/or removing a small bone.
When the bone is removed, the repaired bone may be:
- Stay temporarily with pins or K-wire during healing
- Merged with screws or implants
The most common tool used in hammer surgical correction is K-wire. After the bone is removed and the toes are aligned again, the wire is inserted through the open end of the injured finger to hold the connection in place and stabilize it. The wire remains in place for six weeks during the healing process. K-wires can be painful, uncomfortable and prone to infection. Because of open wounds, K-wires can cause pin tract infections that require additional treatment and make it more difficult for recovery.
Another concern is that the K-cable affects all bones of the corrected finger (even if only the second and third joints require treatment).
Implants are an alternative to K-cable. The previous generation implants are two parts that must be "bundled" during operation. It can be weird to connect and they also run the risk of deciding or even spinning in place, sometimes making the necessary second operation.
Compared to K-wires and other implanted designs, SmartToe implants are completely internal; stabilization does not require the use of external wires when the toes are healed. The ability of "memory" helps compress the joints to the right shape, encouraging rapid fusion. The one-piece design does not disturb the nearby healthy joints, and, it holds the general rotation problem for other operations

Technology
SmartToe implants are constructed of nickel titanium (NiTi), a form of memory alloy commonly referred to by the name, Nitinol. This material is highly biocompatible and has properties suitable for use in orthopedic implants.
SmartToe is the first hammer implant design that utilizes the heat compression properties of Nitinol.
The implant is cooled before surgery, and after implantation, body heat widens and shortens its length. Expansion secures the implant in its place, while its shortening pulls the bones together to encourage natural fusion processes. These compression features reduce healing time.
The shape of the flat design, lateral SmartToe implant refused rotation, an important feature that maintains the correction. Rotation can occur with K-wire and other cylindrical implants. Unplanned rotation can complicate healing and bone fusion.
Attributes
Orthopedic and podiatric surgeons use SmartToe implant reports that help prevent problems associated with external pin fixation, or K-wires, and:
- May reduce healing time due to inherent compression features
- May reduce the possibility of infection because there is no postoperative (postoperative) postoperative exposure
- Does not interfere with healthy connections
- Hold rotation
