Disclosed is a method of preparing a tibial intramedullary canal for receiving a tibial implant such as a stem component of a total ankle replacement prosthesis where an extended cavity is prepared in the tibial intramedullary canal by pulling a tibial reamer bit in the proximal direction from the distal end of a tibia into the tibial intramedullary canal by using a flexible neck tooling introduced through the tibial intramedullary canal from a position proximal to the distal end of the tibia.

Preparing a tibia for receiving tibial implant component of a replacement ankle

An apparatus includes a body extending from a first end to a second end. The first end is a leading end, and the second end includes a first coupling element configured to couple the body to a first other component. The body includes an external fixation element extending along a length of the first component. The external fixation element is configured to engage bone. Systems and methods are also disclosed.

Modular implant with external fixation

A method of ankle replacement includes forming an anterior cut in a bone and forming a stem hole in a distal end of the bone. The stem hole is formed using a plurality of broaches positioned against the distal end of the bone through the anterior cut. A first portion and a second portion of a stem implant are inserted into the stem hole through the anterior cut in the bone. The first portion is coupled to the second portion using a coupling device inserted through the anterior cut in the bone. The stem implant is impacted into the stem hole using an offset impactor.

Anterior ankle approach system and method

Disclosed is are various methods of preparing a tibial intramedullary canal for receiving a tibial implant, methods of preparing a talus for receiving a talar implant, and some examples of a power driver adapter that can be used to carry out the preparation of the tibial intramedullary canal.

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 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.

A system that provides 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.

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 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.

A surgical positioning system including a rotation guide slide and a rotation guide pointer configured to be coupled to the rotation guide slide. The rotation guide pointer includes a base and a pointer extension. The base includes protrusion and a hole extending through the base and the protrusion where the protrusion is sized and configured to be received within a channel such that the rotation guide pointer can translate parallel to a plane defined by the first side of the rotation guide slide. The hole is sized and configured to receive a screw to fix the position of the rotation guide pointer relative to the rotation guide slide, with the protrusion configured to expand when the screw is advanced in the hole.

A surgical alignment system is provided that 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 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.

In various embodiments, a surgical plate includes a body extending between a first planar surface and a second planar surface. The body is configured to couple to a first bone. The first planar surface is configured to couple to a first articulation surface. An anterior articulation portion is coupled to the body. The anterior articulation portion includes a third planar surface extending perpendicular to the first and second planar surfaces and a second articulation surface spaced apart from and coupled to the third planar surface. The second articulation surface is configured to articulate with respect to a second bone.

Anterior resurfacing talar plate

An implant system comprises an implant plate adapted to be positioned on a surface of a resected bone. The implant plate has a plurality of openings. A plurality of independently positionable pegs attach the implant plate to the bone. Each peg has a longitudinal axis and comprises: a peg body and a retaining device. The peg body is inserted into a peg hole in the bone. The peg body has a transverse dimension in a direction normal to the longitudinal axis, the transverse dimension larger than the openings of the plate. The retaining device is separate from the peg body, and is configured to attach to the peg body, with at least a first portion of the retaining device positioned above an upper surface of the implant plate, and a connecting portion of the retaining device extending through one of the openings of the implant plate.

Implant peg with multiple components

Surgical methods are presented for sizing and adjusting a spacer and trial relative to a joint so as to properly position a cutting guide for resection of a bone. The trial may be inserted into a resected space in a first bone, and the spacer may be inserted into one or more channels defined by the trial. The laxity of one or more ligaments may be assessed relative to at least one of the trial and the spacer.
