HyproCure

HyProCure sinus tarsi implant offers a good option in the treatment of hyperpronation for any patient with a flexible flat foot, ages four and up. HyProCure has inherent advantages that make this minimally invasive procedure the ideal solution for the vast majority of flexible flat foot patients from all walks of life.The stent’s design utilizes both the sinus and canalis portions of the sinus tarsi, yielding the best anatomical fit and biomechanical correction. resulting in low removal rate and high patient satisfaction.

This self-seating/positioning implant which is not drilled or screwed into the bone. Rather, it is simply placed inside the space where the ligaments and fibrous tissues will hold it in place by filling its threads and ridges during the healing process.

Features:

Design of the implant has three different distinct sections.

  • The inner/medial portion is threaded; the purpose of this is to lock the implant into the canalis portion of the sinus tarsi. The threads will purchase into the interosseous ligament that helps to reduce backing-out of the implant.
  • The middle section is tapered; this is very important since this is the part that comes in contact with the lateral aspect of the talus and blocks the implant from going any deeper. It takes the guesswork out of the procedure. With other implants it becomes a game of “Is it in too far or not far enough?”. Then intra-op films need to be taken to visualize the location of the implant.
  • The outer larger diameter is smooth and is what actually leads to the prevention of the obliteration (partial/full) of the sinus tarsi. It is very important that this part of the implant has no threads since the lateral process of the talus will come in contact with the implant. Other implants have threads that are very sharp and may lead to damage to this portion of the talus and the sulcus on the calcaneus.

The overall length of the HyProCure stent is longer than other implants. This is allows it to “fill in” the sinus better to give better correction with less of a chance for it to back out. 

The sizing of the implant has been simplified. At the end of the trial sizer is the shape of the HyProCure stent without the threads. This sizer is simply inserted into the sinus tarsi until it won’t go in any more and the forefoot is loaded and the rearfoot is inspected for it’s eversion. If there is greater than three (3) degrees of eversion then the next larger size is inserted until the desired 1-3 degrees is achieved. Finally, when the desired implant is determined and inserted into the sinus tarsi, there is usually under-correction precisely due to the trauma to the area from the previous sizing repetitions.
