Abstract
A system for modifying a talocalcaneal spatial relationship in a foot in a body, including a subtalar spacer having an articulating surface and implanted in the sinus tarsi of the foot and a fastener that fastens the subtalar spacer to a bone surface in the foot, in which the articulating surface of the subtalar spacer directs relative movement between the calcaneus and the talus of the foot.
