Abstract: A resection guide locator includes a bone engagement portion with surfaces that are complementary to the surface topographies of a bone to be resected during surgery. A housing includes a socket defined by a resilient annular wall that is sized and arranged so to accept a resection guide by press-fit to thereby position and hold the resection guide within the socket. The resection guide is maintained in a predetermined, preferred position while the surfaces are releasably locked in position on the bone. A method is disclosed for forming and using the resection guide locator.

Abstract: A method of producing a customized tibial resection guide locator comprising: mapping a contoured surface of the proximal tibia onto a digital model of a resection guide locator to create a digital model of a customized resection guide locator; and manufacturing the customized resection guide locator to include: a complementary surface of the proximal tibia, a wall having a shape that is complementary to an outer profile of a tibial resection guide such that a pocket is defined that is configured to receive the tibial resection guide therein.

Abstract: A system for making a proximal resection of tibia having localized anatomical surface features prior to resection, comprising: a resection guide locator including a body, the body including opposing medial and lateral wings extending outwardly from the body, the body defining a recess being a socket defined by an annular wall, the annular wall including an upper wall, a lower wall, a resection guide having a body defining a resection slot, at least a portion of the resection guide body sized and configured to be received within the recess defined by the resection guide locator.

Abstract: A surgical instrument having a first assembly with a first radio-opaque portion providing a profile of a first portion of an intramedullary implant or canal in a bone, and a second assembly having a second radio-opaque portion providing a profile of a second portion of the intramedullary implant or canal. The surgical instrument may also include a third radio-opaque portion providing an alignment feature to provide a fluoroscopic planar check for the surgical instrument.

Abstract: An example method includes registering, via a visualization device, a virtual model of a portion of an anatomy of an ankle of a patient to a corresponding portion of the anatomy of the ankle viewable via the visualization device, the virtual model obtained from a virtual surgical plan for an ankle arthroplasty procedure to attach a prosthetic to the anatomy. The example method also comprises displaying, via the visualization device and overlaid on the portion of the anatomy, a virtual guide that guides at least one of preparation of the anatomy for attachment of the prosthetic or attachment of the prosthetic to the anatomy.

Abstract: A surgical device includes an body extending from a proximal end to a distal end. The distal end of the body defines a notch sized and configured to receive a reamer. A coupling assembly is supported by the body and includes a reamer guide body disposed at the distal end of the body. The reamer guide body configured to move between a first position and a second position in which the reaming guide body extends at least partially across the notch. A locking assembly is supported by the body and is configured to releasably engage the coupling assembly to maintain the reamer guide body in the second position.

Abstract: A system includes a cartridge having an elongate body extending from a first end to a second end and having a top side and a bottom side. The cartridge defines a first hole adjacent to the first end that extends through the cartridge from the bottom side to the top side. The top side of the cartridge defines a pair of parallel slots that extend perpendicular with respect to a longitudinal axis of the cartridge. Each slot of the pair of parallel slots is equidistant from a central axis defined by the first hole.

Abstract: A method includes mapping a contoured surface of at least one bone onto a digital model of a resection guide locator using a processor to create a digital model of a customized resection guide locator and manufacturing the customized resection guide locator. The customized resection guide locator includes a complementary surface of the at least one bone and a wall having a shape that is complementary to an outer profile of a resection guide and defining a pocket. A first elongate slot and at least one first hole are positioned within the pocket such that the first elongate slot aligns with a second elongate slot defined by the resection guide and the at least one first hole aligns with at least one second hole defined by the resection guide when the resection guide is received within the pocket of the customized resection guide locator.

Abstract: A resection guide locator includes a bone engagement portion with surfaces that are complementary to the surface topographies of a bone to be resected during surgery. A housing includes a socket defined by a resilient annular wall that is sized and arranged so to accept a resection guide by press-fit to thereby position and hold the resection guide within the socket. The resection guide is maintained in a predetermined, preferred position while the surfaces are releasably locked in position on the bone. A method is disclosed for forming and using the resection guide locator.

Abstract: Various surgical devices and methods are disclosed herein. Also disclosed is multi-component prosthesis, which can be used as an ankle prosthesis.
