Systems and methods to evaluate a joint implant device are provided. The joint implant device can include a prosthesis body having a first end and a second end. The first end can couple with a first joint component and the second end can couple with a second joint component. The prosthesis body can include a first support. The prosthesis body can include a first gear rotatably coupled with the first support. The prosthesis body can include a second support movably coupled with the first support. The second support can include a second gear that can engage with a portion of the first gear. The prosthesis body can include a third support. The third support can movably couple with the second support. The third support can move relative to the first support with activation of the first gear.

Arthroplasty implant systems and methods are provided for restoring the functionality of a joint. The arthroplasty implant systems may include a threaded cup having a cylindrical shaped body and a flange. A thread may be provided on the cylindrical shaped body. The thread is configured to engage a bone, and the flange is configured to engage a cortical rim of the bone.

Arthroplasty implant systems and methods are provided for restoring the functionality of a joint. The arthroplasty implant systems may include a modular threaded cup having a cylindrical shaped body and a flange that is removably connectable to the cylindrical shaped body. A thread may be provided on the cylindrical shaped body. The thread is configured to engage a cortical and/or cancellous bone of a bone, and the flange is sized to engage a cortical rim of the bone.

A stemless humeral shoulder assembly having a base member and an anchor advanceable into the base member. The base member can include a distal end that can be embedded in bone and a proximal end that can be disposed at a bone surface. The base member can also have a plurality of spaced apart arms projecting from the proximal end to the distal end. The anchor can project circumferentially into the arms and into a space between the arms. When the anchor is advanced into the base member, the anchor can be exposed between the arms. A recess can project distally from a proximal end of the anchor to within the base member. The recess can receive a mounting member of an anatomical or reverse joint interface.

An inserter includes a first end, a second end, and a body extending between the first end and the second end. A first impacting surface is disposed at the first end, and a second impacting surface is disposed adjacent to the second end. An interface disposed at the second end and is configured to engage an implant. The first impacting surface is configured to direct a first impacting force along the body of the inserter in a first direction, and the second impacting surface is configured to direct a second impacting force along the body in a second direction that is different from the first direction. Methods of use also are disclosed.

According to one aspect of the disclosure, a prosthetic implant system includes a first articulation component, a base, and a second anchor. The base may have a proximal portion and a first anchor extending in a distal direction along a longitudinal first anchor axis. The proximal portion of the base may be configured to couple to the first articulation component. The second anchor may be formed separately from the base and may extend along a longitudinal second anchor axis. The base may include a channel extending from a first opening in the proximal portion of the base through a second opening in a distal portion of the first anchor. The channel may be sized and shaped to receive the second anchor therethrough. When the second anchor is received within the channel, the longitudinal first anchor axis may be oblique to the longitudinal second anchor axis.

A reverse shoulder prosthesis system is provided. The system can include a the convex surface of the glenosphere and the concave surface of the humeral socket. The convex surface, a humeral socket can have a concave surface, and a cup is positioned between cup can be moveable relative to the glenosphere and to the humeral socket.

Prosthesis for a shoulder joint including a humeral component equipped with a stem, a head component and connection or articulation means of the humeral component with the head component, wherein the prosthesis according to the invention can be used both as a conventional prosthesis and as a reverse-type prosthesis.

The subject matter includes systems, methods, and prosthetic devices for joint reconstruction surgery. A computer-assisted intraoperating planning method can include accessing a first medical image providing a first view of a joint within a surgical site as well as receiving selection of a first component of a modular prosthetic device implanted in the first bone of the joint. The method continues by displaying a graphical representation of the first component of the modular prosthetic device overlaid on the first medical image, and updating a graphical representation of the first component based on receiving positioning inputs representative of an implant location of the first component relative to landmarks on the first bone visible within the first medical image. The method concludes by presenting a selection interface enabling visualization of additional components of the modular prosthetic device virtually connected to the first component and overlaid on the first medical image.

Embodiments of devices, apparatuses, kits, and methods for repairing a human joint by suturing biological tissue to the articular surface of a bone at the joint (e.g., repairing defects in the humerus at the glenoid joint after an anterior shoulder dislocation) are described herein. Biological tissue may include hard tissue such as bone or a joint socket or soft tissue such as cartilage, ligaments, tendons, or muscle tissue.
