Patent ID: 8585744

Claim:
An ankle arthrodesis system for providing stabilizing support between a tibia and a talus, the system comprising: a first bone anchoring device having a first end attachable to a first exterior bone surface on the tibia, a second end attachable to a second exterior bone surface on the talus, and an elongated portion extending between the first end and the second end, the elongated portion having an outer diameter; a spacing member comprising a spacer body having a window extending therethrough, the window at least twice as wide as the outer diameter of the elongated portion, the window bounded by a peripheral wall, the peripheral wall irregularly shaped, the spacing member shaped to be inserted between the tibia and the talus to provide load-bearing support between the tibia and the talus; wherein the first bone anchoring device is configured to extend through the tibia, through the spacing member window, and through the talus to provide compression between the first exterior bone surface and the second exterior bone surface; and a second bone anchoring device, wherein the second bone anchoring device is configured to extend through the tibia, through the spacing member window, and through the talus along a trajectory non-parallel to the first bone anchoring device to provide additional compression between the first exterior bone surface and the second exterior bone surface.
