“…The lateral conical portion of the device prevents anterior deviation of the lateral process of the talus and thus stabilizes the sinus portion of the sinus tarsi. Recently, Graham et al (20) conducted a biomechanical investigation on adult human cadaver specimens, in which the distribution of forces on the anterior and posterior aspects of the talocalcaneal joint was studied. They reported that HyProCure Ò promoted uniform distribution of the axial loads and prevented excessive talar subluxation over the calcaneus, which led to improved talotarsal biomechanics.…”

“…It is our belief that asymptomatic patients with RTTD should also be treated, because stabilization of the TTJ complex could prevent or decrease the development of secondary conditions and therefore prevent or decrease the associated economic burden of this disorder, such as time off work and money spent on treatment. Previous reports have indicated that a minimally invasive procedure involving placement of the HyProCure Ò (GraMedica, Macomb, MI) device in the sinus/ canalis tarsi can effectively stabilize the TTJ complex (18)(19)(20). HyProCure Ò (Fig.…”

“…The distal and plantar articular facets of the talus interact with the calcaneus and navicular to form the talotarsal joint (TTJ). The large posterior talocalcaneal joint is responsible to accept a vertical force as much as 80% at heel strike that reduces to slightly greater than 50% of the weightbearing forces at mid-stance (11,12). These forces occur posterior to the posterior aspect of the sinus tarsi ( Figure 1A).…”

Background: Pediatric flatfoot is a common deformity. Unfortunately, the common opinion has been that most children with this faulty foot structure will simply out-grow it, despite no radiographic evidence to support this claim. Every step on a deformed foot leads to excessive tissue strain and further joint damage. Many forms of conservative and surgical treatments have been offered. This study was aimed at investigating the effectiveness of non-surgical and surgical treatment options.Main Text: faulty-foot structure is the leading cause of many secondary orthopedic deformities. A wide range of treatments for pediatric flatfeet have been recommended from the “do-nothing” approach, observation, to irreversible reconstructive surgery. Most forms of conservative care lack evidence of osseous realignment and stability. A conservative surgical option of extra-osseous talotarsal joint stabilization provides patients an effective form of treatment without the complications associated with other irreversible surgical procedures.Conclusion: Pediatric flatfeet should not be ignored or downplayed. The sooner effective treatment is prescribed, the less damage will occur to other parts of the body. When possible, a more conservative corrective procedure should be performed prior to irreversible, joint destructive options.

“…A stable TTM leads to a specific amount of motion between these bones to properly distribute the weight-bearing forces. It acts as a torque converter transferring the forces from the leg through the foot and onto the weight-bearing surface below, and also transforming the ground reaction forces (GRF) acts on the foot into transverse plane rotations of the femoral and tibial components (2)(3)(4)(5). The stability of the talus on the tarsal mechanism depends mainly on the contour of the articular facets followed by the peri-articular ligamentous support.…”

The partial dislocation of the talus on the tarsal mechanism has been recognized as the root cause of multiple foot and lower extremity pathologies. Many conservative and surgical treatments have been utilized to treat this pathologic condition. The purpose of this multi-centered prospective study was to compare weight-bearing radiographic correction achieved in patients with recurrent talotarsal joint dislocation (RTTJD) treated with foot orthoses to that achieved in the same patients through an extra-osseous talotarsal stabilization (EOTTS) procedure. Radiographic data was obtained with no intervention (barefoot), on the orthosis and post-EOTTS from 19 patients (30 feet). Change to the pathologic angles measured for the talarsecond metatarsal (T2M) on the anteroposterior (AP) view and talar declination (TD) angle on the lateral view were analyzed. The reduction in the angles following the use of orthoses was insignificant in both the transverse and sagittal planes. Following the EOTTS procedure, there was a significant change towards accepted normal weight-bearing radiographic angles in the transverse and sagittal planes. In the transverse plane, the EOTTS procedure resulted in an average 58.92% reduction and in the sagittal plane, a 28.32% reduction compared to pre-operative barefoot measurements. By comparison, the change from barefoot measurements to orthosis was 3.20% and 2.20% respectively. The EOTTS procedure did not result in an increase in pathologic angles or cause any angles that were within the normal range pre-operatively to become pathologic. These results support the hypothesis that the EOTTS procedure is more effective in stabilizing RTTJD as compared to orthoses.

Stabilization of Joint Forces of the Subtalar Complex via HyProCure Sinus Tarsi Stent

Abstract: Placement of the HyProCure subtalar stabilization stent in a hyperpronated foot prevents excessive talar subluxation and assists in proper distribution of the axial loads on the subtalar facet joints.
