Displacement / migration of the implant
Even though HyProCure® is inserted correctly at the time of surgery, it is possible for it to shift or displace. Every sinus tarsi is different and HyProCure® may need to “seek its own position.” The stent is only pushed into the sinus tarsi; it is not drilled or cemented. If displacement of the implant does occur, it almost always will happen within the first four weeks post-op. Although it is possible for it to displace after the four-week period, this is extremely rare.
If slight displacement does occur, the implant is holding correction, and the patient has no pain or discomfort, a revision is not needed. If there is loss of correction, the implant will have to be repositioned and the patient will have to be careful with the way he/she walks, etc., during the four to six weeks it takes for the tissues to hold the stent in place. It is possible that even with ideal placement surgically, along with optimum patient compliance, the implant will still displace and migrate. This is due to anatomical variations within the sinus tarsi and inability of the soft tissues to hold the implant in place.
