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.

Patient-specific guides for the Latarjet procedure, as well as surgical systems and methods of performing the Latarjet procedure to treat glenohumeral instability using such patient-specific guides are disclosed. A patient-specific coracoid guide and a patient-specific glenoid guide may be configured based on preoperatively generated three-dimensional models of the patient's shoulder anatomy. Guides may be configured for coracoid graft preparation and glenoid decortication. The coracoid graft may be placed in the desired position based on three-dimensional (3D) preoperative planning.

A system is disclosed herein for providing a kinetic assessment and preparation of a prosthetic joint comprising one or more prosthetic components. The system comprises a prosthetic component including sensors and circuitry configured to measure load, position of load on a curved surface, joint stability, range of motion, and impingement. In one embodiment, the system is for a ball and socket joint of a musculoskeletal system. The system further includes a computer having a display configured to graphical display quantitative measurement data to support rapid assimilation of the information. The kinetic assessment measures joint alignment under loading that will be similar to that of a final joint installation. The kinetic assessment can use trial or permanent prosthetic components. Furthermore, adjustments can be made to the applied load magnitude, position of load, and joint alignment by various means to fine-tune an installation.

An implant extractor assembly that includes a handle, and a mount connectable to the handle. The mount includes a main body, a quick connect about a proximal end of the main body, and an L-shaped connector about a distal end of the main body. The L-shaped connector includes a through hole having a longitudinal axis transverse to a longitudinal axis of the main body.

A humeral implant is disclosed. The implant has a humeral surface component and a stem. The humeral surface component has an articular surface and is configured for fixation to an articular portion of a proximal humerus. The stem is configured for post-surgery axial movement within the humerus. The stem is connected to the humeral surface component opposite of the articular surface. A method of implanting a humeral implant is also disclosed.

The present disclosure provides a glenoid implant system for a reverse shoulder implant system that includes a glenoid implant having a center post, and also includes an angled baseplate comprising a bone facing surface to face an implant site prepared in a glenoid region of a patient, and an implant facing surface to face and engage the glenoid implant and receive the center post of the glenoid implant, wherein the implant facing surface being at an angle with respect to a centerline of the bone facing surface.

Shoulder arthroplasty systems and configurations for components thereof are described. For example, implant systems for a total should arthroplasty (TSA), hemi shoulder arthroplasty, and reverse should arthroplasty (RSA) are described. In addition, exemplary configurations for baseplates, glenoid components, glenosphere components, humeral components, humeral head components, humerosocket components, connectors, and adaptors, are described.

An offset guide that places a surgical tool through a bone of a surgical joint. The offset guide may hold the surgical joint in a reduced configuration at a first location along the bone; the first location preferred for engaging the bone. The offset guide may engage the bone with a hook that engages two opposing sides of the bone to center the surgical tool through the bone. The offset guide may guide placement of a surgical tool through the bone center at a second location along the bone, the second location offset from the first location. The second location may be a preferable location for receiving the surgical tool therethrough. The surgical tool may include both a drill and an implant insertion tool. The implant insertion tool may place an implant at the second location, while the offset guide holds the surgical joint.

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.
