Provided is a prosthesis for ankle arthroplasty including a talar dome component configured to be attached to a talus bone. Also provided is a guide instrument for guiding a reamer to prepare a talus to receive the talar dome component.

Talar implant

Provided is a novel joint replacement prosthesis that includes a base component, and one or more modular stems. The base component includes a bone-facing surface including one or more stem connectors configured for receiving and forming connections with the one or more modular stems inserted from the bone-facing surface side.

Joint replacement prosthesis with trans-cortical stems

Alignment systems and methods are disclosed. A system includes a first component and a second component. The first component has a first body supporting a first alignment member. The second component has a second body supporting a second alignment member. The first and second alignment members are separated from another and are configured to provide an indication that a fluoroscopic device is properly aligned with an anatomical plane when viewed under fluoroscopy. A method includes placing a first component supporting a first alignment member and a second component supporting a second alignment member relative to a patent, and aligning a fluoroscopic device with an anatomical plane using the first and second alignment members.

Alignment systems and methods

A surgical device includes a body having a first side with a first surface that is complementary to a surface of a foreign object disposed within a patient based on preoperative imaging of the patient. The body defines at least one hole positioned relative to the body to facilitate insertion of an elongate device at a predetermined location relative to the foreign object.

Patient-specific surgical devices, system, and methods

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.

Instrument for intra-operative implant templating using fluoroscopy

Various surgical devices and methods are disclosed herein. Also disclosed is multi-component prosthesis, which can be used as an ankle prosthesis. One of the disclosed surgical alignment systems includes a guide arm, a ratchet arm frame configured to be coupled slidably to the guide arm, a ratchet arm configured to be coupled to the ratchet arm frame, and a sagittal 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.

Ankle replacement system and method

A system includes a first spacer sized and configured to be received within a resected bone space of a first bone and a second spacer sized and configured to be coupled to a second bone. The first spacer and the second spacer each include a body extending between a bone contacting surface and a coupling surface. At least one shim is positioned between the first and second spacers. The shim includes a body extending between a first coupling surface and a second coupling surface. The first spacer, the second spacer, and the at least one shim position the first and second bones in a predetermined alignment. An adjustable guide including a guide adapter and a guide body is configured to couple to the first spacer and is adjustable on a first axis.

Joint osteotomy system and method

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.

Virtual guidance for ankle surgery procedures

A resection guide includes a first body portion and a second body portion. The first body portion has a first bone engagement structure and defines a first plurality of holes. The second body portion has a second bone engagement structure and defines a second plurality of holes. The first body portion and the second body portion are operable to separate a first anatomical structure of a patient and a second anatomical structure of the patient. A cutting guide defines at least one guide aperture that is operable for guiding a cutting tool for use in resecting a portion of the second anatomical structure of the patient. The cutting guide is positionable relative to the first body portion.
