A New Approach For Correcting Hammertoe Deformities

Final Thoughts
Using the StayFuse implant gives you several advantages in comparison to other procedures. The three-step technique for implantation is very simple to perform, with minimal instrumentation. A range of diameters and lengths are available, depending on bone size. There is no disruption of the joints, proximal or distal, to the PIPJ. Employing the device enables you to provide a more stable union with added rotational stability. This improved fixation enhances the healing process.
There is no post-op implant exposure, which eliminates pin tract infections. Without an external wire and when you compare it to traditional K-wire fixation, the implant improves patient comfort as well as patient perception and can reduce the prolonged need of a post-op shoe. If the situation arises, you do have the option of removing the device later via a “windowing” technique through the middle phalanx. The only real disadvantage I see with the device is the inability to concurrently stabilize across the metatarsophalangeal joint with pinning, if this was so desired for mechanical or structural reasons.
In comparison to the other digital arthrodesis procedures performed, I have found the StayFuse implant to be an excellent device. It is coupled to a relatively simple implantation procedure and has had reproducible results. I have addressed digits two through four using the implant. (The fifth toe usually is best addressed with a simple arthroplasty at the PIPJ.)
It is up to your discretion whether adjunctive soft tissue procedures (i.e. tenotomy, capsulotomy, etc.) are needed along with the StayFuse. I believe that using the implant leads to fewer complications, such as nonunions, pseudoarthroses, pin tract infections, pain and need for revisional surgeries. In particular, the appearance of a somewhat “bulbous” fused PIPJ — which you’ll often see with the “offset” arthrodesis of the peg-in-hole procedure — is well addressed with the StayFuse implant.
