  • Publication number: 20190254688
    Abstract: A position adjustment device having a tool holder is locked to at least two pins projecting from respective anterior facing locations near a distal end of a tibia of a patient. The position adjustment device is adjusted. The position adjustment device is locked with the tool holder at first coordinates in the proximal-distal and medial-lateral directions. The distal end of the tibia is resectioned with a tool positioned on the tool holder, while the tool holder is in the first coordinates in the proximal-distal and medial-lateral directions. The tool is removed from the tool holder. A tibia trial is placed on the resectioned tibia using the tool holder, while the tool holder is in the first coordinates in the proximal-distal and medial-lateral directions. The tibia trial has a size and shape of a tibial tray of an ankle replacement system.

  • Patent number: 10149687
    Abstract: A cutting system includes a cutting base and a first cutting guide. The cutting base has a body including a first flange, a second flange, and defines a first slot. A first set of holes is defined in the first flange, and a second set of holes is defined in the second flange. The first cutting guide has a body defining at least one opening. The first cutting guide also includes a set of pegs that extend inferiorly from the body. The set of pegs is sized and configured to be received within the first set of holes to align the at least one opening with the first slot in a first orientation and to be received within the second set of holes to align the at least one opening with the first slot in a second orientation.

  • Patent number: 9993255
    Abstract: A system includes a guide arm, a ratchet arm frame configured to be coupled to the guide arm, a ratchet arm configured to be coupled to the ratchet arm frame, and a sagittal sizing guide body configured to be coupled to the ratchet arm. The sagittal sizing guide body includes a first radiopaque object disposed at a first position and a second radiopaque object disposed at a second position that is spaced apart from the first position. The first radiopaque object has a length that corresponds to a length of a second prosthesis component. When the surgical alignment system is positioned for use on a patient, the first radiopaque object identifies a location at which a first resection of a first bone is to be performed. The second radiopaque object has a profile that corresponds to a profile of a first prosthesis component for installation on a second bone.
