Instruments, guides, systems and related methods for total ankle prostheses are disclosed. The instruments, guides, systems and related methods facilitate preparation of a tibia and/or talus of a patient for implantation of a total ankle prosthesis therein. The instruments, guides, systems and related methods also facilitate selection of a particular size of a tibial component, a talus component and/or a tibial insert of the total ankle prosthesis that suits the patient. The instruments, guides, systems and related methods include a tibial trial component, a talar trial component and tibial insert trial component that replicate one or more aspects of the tibial component, the talus component and the tibial insert, respectively, of the total ankle prosthesis. The talar trial component includes an articulation surface that articulates with the tibial insert trial component, and slots that facilitate chamfered resection of the patient's talus for the implantation of the talus component thereon.

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.

The present disclosure pertains to ankle prostheses. In an example embodiment, the ankle prosthesis comprises an adjustable and replaceable intermediate implant that is disposed between a tibial implant and a talar implant. The intermediate implant is adjustable relative to the tibial implant and can be interlocked therewith once adjusted. Methods of using, fitting, and adjusting the device are also described. Still other embodiments are described.

A system comprised of custom radiographically designed tibial and talar cutting guides, a tibial reaming guide and bit, and instrumentalities for use in total ankle replacement surgery and a computer-based system and method for making the custom radiographically designed tibial and talar cutting guides.

The present invention is an internal osseointegrated transfemoral amputee implant device and related methods. The device is designed to restore the enclosed nature of the bone marrow system which is disrupted by amputation, plus provide a pressure tolerant (weight-bearing) surface and mechanical anchoring for the iliotibial band.

Devices and methods for performing a surgical step or surgical procedure with visual guidance using an optical head mounted display are disclosed.

Devices and methods for performing a surgical step or surgical procedure with visual guidance using an optical head mounted display are disclosed.

An implant is provided for use in an ankle joint between reconditioned end surfaces established on a distal end of an upper tibia bone and an opposing lower talus bone. The implant comprises a substantially porous rigid component adapted to be anchored against the upper tibia reconditioned end surface and the lower talus reconditioned end surface. The component defining an opening therethrough. An intramedullary nail is configured to pass through the opening in the component when the nail is driven through the talus and into the tibia.

An implant includes a component for fixed attachment to a bone. An underpass layer of a porous material is disposed on a first side of the component for fixed attachment. At least one strut is provided on the underpass layer. The at least one strut has a first surface contacting the underpass layer and a second surface opposite the first surface. The at least one strut comprises a non-porous material. An additional layer of the porous material fills a respective volume adjacent the at least one strut. The additional layer extends from a first side of the underpass layer to a predetermined height at or above the second surface of the at least one strut.

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.
