A glenoid component in one embodiment includes a base component with a planar upper circular rim defining a first plane, a receptacle opening to the first plane, a lower planar circular surface defining a second plane parallel to the first plane, and a conical outer wall extending from the upper circular rim to the lower planar circular surface. The glenoid component includes an articulating component with an upper articulating surface and a lower coupling portion configured to be inserted into the receptacle.

An expandable fusion device is capable of being installed inside an intervertebral disc space to maintain normal disc spacing and restore spinal stability, thereby facilitating an intervertebral fusion. The fusion device may include a body portion, a first endplate, and a second endplate, the first and second endplates capable of being moved in a direction away from the body portion into an expanded configuration or capable of being moved towards the body portion into an unexpanded configuration. The fusion device is capable of being deployed and installed in both configurations.

An implant system includes a first portion, a second portion, and a third portion. The first portion includes a hydrogel; the second portion includes a porous material and the hydrogel in pores of the porous material; and the third portion includes the porous material. The first portion is free of the porous material and the third portion is free of the hydrogel. The third portion has non-uniform lateral cross-section.

This invention provides optimized solid substrates for promoting cell or tissue growth or restored function, which solid substrate comprises aragonite and is characterized by a specific fluid uptake capacity value of at least 75%, or a contact angle value of less than 60 degrees when in contact with a fluid and which is further characterized by tapered sides and tools for implantation of optimized solid substrates.

A device for facilitating the formation of new bone tissue includes a body that defines an upper portion and a lower portion, the lower portion having a substantially frustum-like shape, the upper portion having a substantially cylindrical shape. The lower portion is adapted to be inserted into the medullary canal of a bone.

The present invention is an internal osseointegrated transfemoral amputee implant device and related methods. The device is designed to restore the enclosed nature of the bone marrow system which is disrupted by amputation, plus provide a pressure tolerant (weight-bearing) surface and mechanical anchoring for the iliotibial band.

Systems for arthroplasty, and methods of designing an arthroplasty system, such as in reverse arthroplasty, are provided that include an increased impingement-free range of motion. The systems and methods provide for a geometry of the reverse components to address the deficit of limited range of motion included with conventional reverse arthroplasty and thereby enhance a patient's quality of life.

Disclosed is a distal radio ulnar joint prosthesis system, and the method of use for the same, the system comprising an ulnar stem component, and ulnar head component, a set screw, and a sigmoid notch component, the system providing a prosthesis for replacement of the distal radio ulnar joint to restore the pronation-supination motion of the forearm as well as stability between the ulna and radius; a DRUJ prosthesis adapted for rotational alignment of the replacement joint along the axis of forearm rotation; a DRUJ prosthesis which allows for the use of a number of different sized heads having differing geometries; a DRUJ prosthesis adapted for variable pivoting alignment between the replacement distal ulnar head and the ulna; and a DRUJ prosthesis adapted for adjustment in the alignment between the articulating surface of the ulnar head and the sigmoid notch.

The present invention provides an expandable fusion device capable of being installed inside an intervertebral disc space to maintain normal disc spacing and restore spinal stability, thereby facilitating an intervertebral fusion. In one embodiment, the fusion device includes a body portion, a first endplate, and a second endplate, the first and second endplates capable of being moved in a direction away from the body portion into an expanded configuration or capable of being moved towards the body portion into an unexpanded configuration. The fusion device is capable of being deployed and installed in both configurations.

A glenoid implant system may include a main body formed of a polymer, a base, and an anchor formed of metal. The main body may define an articulating surface and an opposite bone-contacting surface. The base may be formed in the bone-contacting surface of the main body, the base including a hole formed therein. The anchor may have a main section and a threaded post extending from the main section. The anchor may include a plurality of ribs extending in a longitudinal direction of the main section, the plurality of ribs being spaced apart from one another in a circumferential direction of the main section. The anchor may further include a plurality of wedges disposed on a base of the anchor, the plurality of wedges adapted to contact the base formed in the bone-contacting surface of the main body when the threaded post is received within the threaded hole.
