E.O.T.T.S. stands for extra-osseous talotarsal stabilization. This is a minimally invasive procedure where an FDA cleared titanium stent is placed into a naturally occurring space in between the ankle and heel bones. This space, called the sinus tarsi, should always be open. There is no drilling or cutting with this procedure. The ankle bone is re-positioned on the heel bone which re-opens the space. The space is then sized to determine which size stent stabilizes the ankle bone while still allowing the normal amount of hindfoot motion. The stent is held in place by the bony chamber and the soft tissues found in this space. Atlas-FAI only uses the HyProCure stent (made by GraMedica®). This stent has the greatest success rate, is time-tested, and back by scientific research.
The EOTTS-HyProCure procedure is normally performed under a local anesthesia; some patients also prefer to have an IV sedation to completely relax them during this 20 minute procedure. One of the many advantages with this procedure is that it can be performed on both children and adults. Even when the HyProCure stent is placed into a child’s foot, it is unlikely that it will have to be replaced later in life. The good news is that the procedure is reversible if needed.
Once cleared by your Atlas-FAI specialist, patients are allowed to return to their normal activity level. Of course since you will now have a realigned foot, certain tissues don’t have to work as much whereas others will have to work a little more. So there will be a period of adjustment and this differs from foot-to-foot and patient-to-patient. It’s kind of like working-out for the first time.
