Technology Summary
In orthopedic surgery, nails are frequently used to fuse joints.  In orthopedic ankle surgery, there is no nail currently available with the ability to fuse the ankle joint without also fusing the subtalar joint.  This results in substantial arch pain for the patient as well as decreased mobility and impaired gait.  This technology provides a new type of nail design that can fuse ankle joints without also fusing the subtalar joint while also aiding in compression and stability with strategically placed locking screws.  It represents a significant improvement in this type of surgery.  A provisional patent was filed last year on the latest model, one that has incorporated improvements from earlier generations based on information learned in multiple cadaveric studies.
