  • Publication number: 20190091032
    Abstract: The present disclosure includes, in one embodiment, a talar component of an ankle joint prosthesis for engagement with a talus bone having a medial side wall and a lateral side wall, opposite the medial side wall, each side wall terminating at a distal edge, and the distal edges adapted to drive into the talus bone. When implanted, the side walls may form a seal between the talus bone and the component to prevent fluid from flowing under the component.

  • Publication number: 20170027589
    Abstract: In one embodiment, the present invention includes a method of alignment for resection of tissue including obtaining a surgical device comprising an alignment guide, a first guide structure and a second guide structure; securing the alignment guide to a bone, the alignment guide including a positioning block; placing the first guide structure onto the positioning block of the alignment guide; viewing a target location of a first resection plane on the bone using the first guide structure; adjusting the target location of the first resection plane by adjusting a position of the first guide structure; attaching the second guide structure to the first guide structure; viewing a target location of a second resection plane on the bone using the second guide structure; and adjusting the target location of the second resection plane by adjusting a position of the second guide structure.

  • Publication number: 20160135815
    Abstract: One aspect of the present invention relates to a tissue resection guide that includes a central body, a first flange and a second flange, the flanges having first and second guide surfaces, respectively, suitable for use in tissue resection. Each guide surface lies on a cutting plane, both planes intersecting interior to the flanges. In the embodiments described, the availability of two cutting planes ensures resections in more than one plane are possible. As a result, bone segments can be removed via a cut on two planes without the need to cut across an entire section of bone on one plane. In some embodiments, an opening exists between the first flange and the second flange to ensure that each resection overlaps. In other aspects of the invention, systems and methods of use for the tissue resection guide are described.
