Project Description

Horizon™ Subtalar

The BioPro Horizon Subtalar Implant is used for the treatment of flatfoot and posterior tibial tendon dysfunction in both children and adults. Implanted within the sinus tarsi, it is designed to block excessive pronation while allowing normal subtalar joint motion.


  • A smooth lateral surface ensures both the talus and calcaneus interface with a smooth surface during pronation.
  • The slight taper on the smooth lateral surface stabilizes the implant during pronation and protects against lateral migration.
  • Cannulated to allow easy insertion over a guide wire.
  • A hybrid design incorporates a polyethylene sleeve over the lateral portion of the implant, offering a softer, more forgiving surface to interface with the talus and calcaneus.
