System and method for modifying talocalcaneal relationship in a foot

摘要

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.

主权项

1. A method for modifying a talocalcaneal relationship in a foot comprising implanting a subtalar spacer system within said foot, wherein said implanted subtalar spacer system comprises:
a first subtalar spacer comprising:
a first spacer mount portion having a body defining a recess and a bore, the recess extending into the body of the first spacer mount portion and the bore extending through the body of the first spacer mount portion;a first spacer body portion having a body that defines an insert member, articulating member, and an aperture that extends through the body of the first spacer body portion, the insert member disposed within the recess of the first spacer mount portion, the articulating member of the first spacer body portion defining an articulating surface;a first attachment member attached to the first spacer mount portion, the first attachment member having a body that defines a support member that extends through the aperture defined by the first spacer body portion;a second attachment member attached to the first spacer mount portion wherein the second attachment member has a first end and a second end; anda first fastener disposed through the bore of the first spacer mount portion and attaching the first spacer mount portion to a bone within said foot.
