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.

A device including a delivery port and a method of delivering a material via a delivery port is disclosed. The device includes a body extending between a proximal surface and a distal surface. The body is sized and configured to be coupled to an anatomical structure at an implantation site. A first inlet port is formed in a distal surface of the body and is sized and configured to receive a first material. A first outlet port is formed in the proximal surface of the body. The first outlet port is coupled to the first inlet port by a first fluid path defined by the body and the first outlet port is sized and configured to provide the first material to a first predetermined location when the body is coupled to the anatomical structure.

Proposed is an artificial ankle joint bearing element in which a contact area of the bearing element with a talus element is increased such that stress is evenly distributed during bearing movement of the bearing element on the talus element and wear of the bearing element is reduced under the same load; the bearing element has a front and a rear convexly formed to increase a contact area with a tibial element and distribute stress; and the front and rear of the bearing element are asymmetrically formed such that the rear thereof is formed to have a smaller height than the front thereof so as to facilitate the insertion of the bearing element into space between the talus element and the tibial element from an anterior side thereof during artificial ankle joint surgery.

Disclosed is a system and method for fusing two bones within a mammal. More particularly described is such a system and method for a transcortical fusion system wherein which a plate is affixed in a longitudinal slot or aperture cut into the anterior portion of the tibia and the talus, thereby achieving a fusion of the joint while placing the fusion site in the joint in compression.

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.

An ankle arthroplasty system may have a talar prosthesis and a tibial prosthesis, each of which has an articular surface and a bone engagement surface. Each bone engagement surface may have an anterior-posterior curvature and a medial-lateral curvature with a convex shape. A burr with a rotatable cutting element may be used to form a prepared surface on the talus or the tibia to receive the corresponding prosthesis. A cutting guide may be used to guide motion of the burr; the cutting guide may include a base and an arm movably coupled to the base. One of the base and the arm may have a guide surface, and the other may have a follower that slides along the guide surface to constrain motion of the burr such that the prepared surface has at least one concave curvature and one convex curvature.

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.

Devices, systems, techniques and methods for determining the fit of an implant and for determining one or more prognosticators, indicators or risk factors of postoperative performance are provided.

A system or kit includes a rotating tool and a guide. The rotating tool includes an elongated shaft with at least one cutting edge. The rotating tool is configured to remove bone from a patient. The guide includes a body comprising a contact surface and a guide channel. The contact surface is configured to position the guide relative to a patient or an implant. The guide channel is configured to receive the elongated shaft and to allow the cutting edge to be swept along a path. The path corresponds to a portion of the bone to be removed. A method of removing an implant includes forming an incision in a patient. The method further includes inserting a rotating tool into the incision such that a cutting edge of the rotating tool is adjacent to a surface of the implant. The method further includes sweeping the cutting edge along a first path adjacent to the surface of the implant to remove bone adjacent to the implant.

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.
