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.
Claims20
An apparatus, comprising:
- a subtalar spacer configured to be implanted in the sinus tarsi of the foot, the subtalar spacer including:
- a spacer body portion including an articulating surface, the spacer body portion shaped to fit within and fill a portion of the sinus tarsi so as to elevate the talus bone relative to the calcaneus bone, the articulating surface contoured to articulate with one of an inferior surface of the talus bone or a superior surface of the calcaneus bone;
- and
- a spacer mount portion including an exterior side shaped to complement a contour of the other of the inferior surface of the talus bone or the superior surface of the calcaneus bone and including one or more features to promote bony ingrowth into the apparatus.
1 more element
An apparatus for modifying a talocalcaneal spatial relationship in a foot, comprising:
- a first subtalar spacer configured to be implanted in the sinus tarsi of the foot, the first subtalar spacer including a first spacer body portion and a first spacer mount portion, the first spacer body portion including a first articulating surface, a first base surface, and an outer surface extending from the first articulating surface to the first base surface;
- a second subtalar spacer configured to be implanted in the sinus tarsi of the foot, the second subtalar spacer including a second spacer body portion and a second spacer mount portion, the second spacer body portion including a second articulating surface;
- wherein the first subtalar spacer and the second subtalar spacer are collectively shaped to fill a portion of the sinus tarsi and the first articulating surface is configured to articulate with the second articulating surface to direct relative movement between the talus bone and the calcaneus bone of the foot.
