Provided is a total talar replacement prosthesis that has a metallic body shell and a metallic or biologic core, where the metallic body shell includes one or both of a removable calcaneus attachment and a removable navicular attachment. The attachments, when removed, exposes a respective calcaneus-facing surface or a navicular-facing surface that can enhance fusion to the respective bones, calcaneus and/or navicular.

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.

A unibody implant movable between an expanded position and a contracted position is disclosed. The unibody implant may include a unitary expandable body defined by an inferior portion and a superior portion that are connected together. In various embodiments, a set screw may be rotatably supported by the body and configured to move a plug having a first inclined surface facing the distal side. In various embodiments, the set screw may be movable in the longitudinal direction towards the distal side upon rotation of the set screw along the rotation axis, for example. In various embodiments, movement of the set screw urges the plug against the superior portion thereby expanding a vertical distance between the superior and inferior sides of the body. In some embodiments, the plug may include a stabilizing element configured to transfer compressive forces between the superior portion and inferior portion.

A craniofacial implant includes a craniofacial implant body and a passive pressure sensor. The craniofacial implant body permits measurement of the passive pressure sensor via externally applied stimuli passing through the craniofacial implant body.

A method of forming a shoulder prosthesis includes resecting an end portion of a humerus to form a resected end of the humerus and a resected portion separated from the humerus, the resected portion having an outer convex surface and an inner surface. The inner surface of the resected portion is processed to include a concave articular surface. The outer convex surface of the resected portion is implanted in the resected end of the humerus. An implant having a convex articular surface is secured to a glenoid. The concave articular surface of the resected portion is articulated with the convex articular surface of the implant.

An osteotomy implant includes a first surface extending generally in a first plane and a second surface extending generally in a second plane, oblique to the first plane. The first surface has a perimeter having a first linear edge, a first curve edge connected to the first linear edge, a second linear edge connected to the first curved edge, and a second curved edge connected to the second liner edge.

According to one example, a tibial prosthesis that can include a tibial bearing component, tibial baseplate, an insert and a fastener. The tibial bearing component can have medial and lateral proximal articular surfaces and an opposing distal surface. The tibial bearing component can define at least one recess therein with the recess having an opening at a periphery of the tibial bearing component. The tibial baseplate can be coupled to the tibial bearing component on the proximal surface thereof and having a distal surface configured to be disposed on a resected proximal surface of a tibia. The insert can be configured to be disposed within the recess and can engage the tibial baseplate and the tibial bearing component. The fastener can be insertable into the tibial bearing component and can be configured to retain the insert to the tibial baseplate.

The present disclosure relates to an expandable interbody that includes superior and inferior shells enclosing a control mechanism that includes interlocking proximal and distal cages as well as an adjustment screw that longitudinally translates the distal cage relative to the proximal cage and thereby expands interbody by pushing apart the distal ends of the superior and inferior shells.

A pedicle bone fastener may include a shaft, a helical thread, and an integrated attachment feature. The shaft may include a proximal end, a distal end, and a longitudinal axis. The helical thread may be disposed about the shaft along the longitudinal axis between the proximal and distal ends of the shaft. The helical thread may include a first undercut surface and a second undercut surface. The first undercut surface may be angled toward one of the proximal end and the distal end of the shaft and the second undercut surface may be angled toward the other one of the proximal end and the distal end of the shaft. The integrated attachment feature may be disposed at the proximal end of the shaft and configured to be adjustably secured to a spinal stabilization implement.

An intervertebral implant frame that is configured to engage a spacer can include a pair of arms that extend longitudinally from a support member such that the arms engage the spacer. The spacer can be made from bone graft, and include a first spacer body made of cortical bone, and a second spacer body made of cancellous bone.
