The present disclosure is directed offset adapters, trial implant systems, shoulder implant systems, and methods for total shoulder replacement, wherein the eccentricity of a humeral head relative to a humeral anchor and resected proximal portion of a humerus is selectable by a surgeon. A humeral head implant system includes a humeral head, an adapter, and humeral anchor. An offset adapter is operable to connect the humeral head to a humeral anchor. The offset adapter includes a first tapered cylindrical portion having a first axis, a second tapered cylindrical portion having a second axis, and the first axis being eccentrically disposed relative to the second axis of the adapter. A trial humeral head system includes a trial humeral head, a pin guide, and a trial adapter.

A humeral head implant system includes a head component including a first articulating surface, a second bottom surface extending from the first spherical articulating surface, a first cavity extending a first distance into the head component from the second bottom surface, and a second cavity extending into the head component along a cavity axis. The head component defines a head axis extending through a center of the first articulating surface parallel to the cavity axis. A base component defines a slot extending from a first width to a second width. An insert component includes an insert body, a first engagement feature, and a slot engagement feature. The first engagement feature is received in the second cavity along the cavity axis. The insert body has an insert thickness less than the first distance, and the slot engagement feature slides into the slot in a direction transverse to the cavity axis.

A joint replacement system for repairing an articular surface of a first bone of a joint includes an anchor portion and an implant portion. The anchor portion includes an anchor to be secured to the bone, and an anchor fixation head including a bone-facing surface (BFS) extending radially outward from the anchor and an implant facing surface (IFS) extending from a periphery of the BFS. The implant portion is formed from a material (e.g., CoCr) more dense than the material of the anchor portion (e.g., Ti) and includes a fixation cavity to receive at least a portion of the anchor fixation head (AFH), the fixation cavity includes an anchor facing surface (AFS) configured to form a frictional connection with the IFS, and a load bearing surface having a contour for articulating against a cooperating articulating surface of a second bone of the joint.

The invention features a glenoid (shoulder socket) implant prosthesis, a humeral implant prosthesis, devices for implanting glenoid and humeral implant prostheses, and less invasive methods of their use for the treatment of an injured or damaged shoulder.

A tibial-tray system may include a tibial tray and a spline configured to extend proximally from the tibial tray and guide a femoral component of a knee system. The tibial-tray system may also include an adapter configured for attachment to the tibial tray and the spline. A distal end of the adapter may have a position relative to a position of a proximal end of the adapter such that the spline extends upward from the tibial tray at a predetermined position.

An implant is disclosed that a base member configured to be secured in bone, the base member includes a plate portion, an articulating member, and a coupling portion for securing the base member to the articulating member. A stem extends from the plate portion, where the stem is positioned offset from a center of the plate portion. The coupling portion includes a first fixation component, and a second fixation component including an opening for receiving the first fixation component, where the first fixation component is coupled to the articulating member and the second fixation component is coupled to the base member.

The invention relates to an augmentation device comprising an annular cone surrounding a channel extending through the cone from a proximal cone end to a distal cone end of the cone. The invention further relates to an augmentation system comprising such an augmentation device and an applicator, as well as an implantation method of an augmentation device using such an augmentation system.

The invention relates to a glenoid (shoulder socket) implant prosthesis, a humeral implant prosthesis, devices for implanting glenoid and humeral implant prostheses, and less invasive methods of their use for the treatment of an injured or damaged shoulder.

Intervertebral implants for implanting into an intervertebral space are provided. The implants can comprise one or more layers that are operably attached to one another. An implant can comprise a first layer having a first mating surface that mates with a second mating surface of a second layer. The first mating surface and the second mating surface can have features that allow them to complement each other. The implants can include one or more bore holes for receiving a fixation member. The bore holes can be horizontal, vertical or diagonal. In some cases, the bore holes will be blind bore holes.

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.
