HyProCure is an extra-osseous talo-tarsal stabilisation (EOTTS) procedure designed to help people with symptomatic Pes planus(flat-foot) deformity.  This is a minimally invasive procedure that does not require cutting or drilling in the bones. A small titanium stent is placed into a naturally occurring space called sinus tarsi between the ankle and heel bone to instantly realign and stabilize the hindfoot.

Although HyProCure is usually performed as a stand-alone, single procedure, there may be additional surgical procedures required for more complex cases.




  • Reversible
  • Works with or without shoes
  • Stabilises and realigns the ankle bone(talus)
  • Patients are back into shoes within a few days to weeks
  • The normal amount of hindfoot motion still occurs
  • Prevent collapse of the arch
  • Decreases stains to the plantar fascia, posterior tibial tendons
  • The lowest removal rate of any sinus tarsi implants (less than 6%)



The procedure can be done under local or general anaesthesia.

A small incision (2cm) is made over the ankle joint area(sinus tarsi) and dissections carried out to expose sinus tarsi. A small size implant is then inserted in the sinus tarsi under the guidance of live x-ray and skin closed with 1-2 stitches.



Non-weightbearing period of 3-5 days is recommended and partial weightbearing in Cam Walker continues for 2-4 weeks.

Patients are back to normal walking within a few weeks although this may vary from patient to patient.  The bones, tendons and ligaments throughout the foot and rest of the body will adapt to the corrected position over the following several months.


Frequently Asked Questions about HyProCure

Are there any limitations, as far as sports go, after this procedure?

Once the tissues surrounding the stent are healed, there should be no limitation. The abnormal motion is no longer present and normal motion will occur. Usually, there is a significant improvement in running, jumping and any activity involving propulsion from the foot.

If this procedure is performed on a child, does it have to be replaced later in life?

The short answer is likely no, but this is not a guarantee. Normally, once the stent is inserted into the foot it never has to be changed. The bones will continue to grow peripherally around HyProCure.

Will I feel the implant in my foot?

As long as the implant does not displace, you should not be able to feel HyProCure after the procedure. Sometimes for the first few months, a hard substance may be felt in the area of the surgery. This is scar tissue and should dissipate after several months if present at all.

Will I still have to wear my orthotics after the procedure?

If the orthotics were dispensed to treat hyperpronation then you will no longer need them. However, there are other reasons for orthotics to be worn. Orthotics can be used to off-weight prominent areas to the bottom of the foot. If those areas are not surgically addressed, then orthotics may still be required after the procedure.

Are there limitations to this procedure?

Yes, every surgical procedure has its limitations. In very severe cases of talotarsal displacement, other surgical procedures may be necessary to achieve optimum correction.


Any surgical or invasive procedure carries risks. Before proceeding, you should seek a second opinion from an appropriately qualified health practitioner
