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 temporomandibular joint replacement system includes a condylar component secured with a mandibular bone and a fossa component with a fossa backing secured with a zygomatic bone and slidably attached with a removable fossa lining, the fossa lining having an open-ended concave fossa dome with a post-center peak to allow for mediolateral and anterior translation with a rounded, oblong condylar head of the condylar component. The slidable attachment mechanism of the fossa backing and fossa lining is laterally-oriented to allow for post-implantation removal and replacement without disturbing any bone or bone-interfacing components. The bone-interfacing surfaces are anatomically-contoured to their respective bone surfaces and formed with materials and textures which promote osseointegration with the joint replacement.

Devices and methods for treating one or more damaged, diseased, or traumatized portions of the spine, including intervertebral discs, to reduce or eliminate associated back pain. In one or more embodiments, the present invention relates to an expandable interbody spacer. The expandable interbody spacer may comprise a first jointed arm comprising a plurality of links pivotally coupled end to end. The expandable interbody spacer further may comprise a second jointed arm comprising a plurality of links pivotally coupled end to end. The first jointed arm and the second jointed arm may be interconnected at a proximal end of the expandable interbody spacer. The first jointed arm and the second jointed arm may be interconnected at a distal end of the expandable interbody spacer.

An implant for a human includes a body having a superior surface, an inferior surface, a distal surface, and a proximal surface. The proximal surface is configured to engage the talus and the calcaneus of an adult human, and the distal surface configured to engage at least the first and fourth metatarsals of the adult human. The distal surface has a largest distal height and a largest distal width that is greater than the largest distal height, and the proximal surface has a largest proximal height and a largest proximal width that is greater than the largest proximal height.

In an artificial knee joint implant, an increase in constraint force of a femur component and a tibia component in the anterior-posterior direction and the left-right direction of a patient is enabled, and an increase in an allowable degree of medial pivot motion is enabled. An artificial knee joint implant has a femur component to be fixed to a distal portion of a femur of a patient, and a tibia component to be fixed to a proximal portion of a tibia of the patient. Femur sliding faces of the femur component and tibia sliding faces of the tibia component each include a region in which the curvature radius varies in a predetermined direction.

Embodiments of forming custom interbody implants that may be used to stabilize region(s) formed between mammalian bony segments, including systems and methods to produce a custom interbody element that may be used to stabilize or couple region(s) formed between two or more mammalian bony segments. Other embodiments may be described and claimed.

The disclosure relates to a reconstruction prosthesis including a main section, at least one serpentine structure, and at least one mount section. The at least one serpentine structure is connected to one end of the main section. The at least one mount section is connected to the main section via the at least one serpentine structure. The at least one mount section is configured to be connected to osseous tissue. When the at least one serpentine structure is deformed by force, the relative position of the main section and the at least one mount section is changed.

Methods of implanting a talar component during ankle surgery are provided. A method includes cutting at least medial and lateral cuts in a talus bone. The method includes driving a first self-cutting distal edge of a lateral side wall of the talar component into the lateral cut and a second self-cutting distal edge of a medial side wall of the talar component into the medial cut. A thickness of the lateral sidewall tapers to form the first self-cutting distal edge and a thickness of the medial sidewall tapers to form the second self-cutting edge.
