Abstract
An implantable fixation system for fusing a joint between a first bone and a second bone. The system may include an anchor, standoff, bolt, and cortical washer. The system may be implanted across the joint along a single trajectory, the length of the system adjustable to provide compressive force between the anchor and the cortical washer. The system may be implanted across a tibiotalar joint with the anchor positioned in the sinus tarsi. A spacing member may be inserted between the two bones and the fixation system implanted to extend through an opening in the spacing member. The spacing member may be anatomically shaped and/or provide deformity correction. An ankle arthroplasty system may include a tibial plate, a talar plate, and a bearing insert. The plates may be anchored to the tibia and talus along a single trajectory. The ankle arthroplasty system may be revisable to a fusion system.
