Subtalar Arthroereisis


Arthroereisis is a surgical procedure that purposely limits movement across a joint. Subtalar arthroereisis or extraosseous talotarsal stabilization is designed to correct excessive talar displacement and calcaneal eversion by reducing pronation across the subtalar joint. Subtalar arthroereisis is being evaluated as a treatment of flexible flatfoot and talotarsal joint dislocation. It is performed by placing an implant in the sinus tarsi, which is a canal located between the talus and the calcaneus. Conservative treatments include orthotics or shoe modifications.

A number of implants have been cleared for marketing by the U.S. Food and Drug Administration through the 510(k) process since 1996. These include: Subtalar MBA®, OsteoMed Subtalar Implant System, BioPro Subtalar Implant, HyProCure Subtalar Implant System, MBA Resorb Implant, Metasurg Subtalar Implant and Subtalar Implant.




The evidence for subtalar arthroereisis includes mainly single-arm case series and one small nonrandomized controlled trial.  Some studies report high rates of complications and implant removal.  The evidence is insufficient to determine the effects of the technology on health outcomes.
