An improved modular rotational device includes a first and second threaded coupler for affixation along the stem of an endoprosthetic device, for example, a humeral prosthesis or a femoral prosthesis. The rotational device axis of rotation is coaxial with the stem, and its axis of rotation is located in close proximity to the intramedullary stem of the prosthesis or in close proximity to the distal articulation of the prosthesis. A housing has a proximal and distal end with an axial bore therethrough for receiving an elongated stem of the device. A lobe ring may be utilized to limit the axis of rotation of the device. Additional endoprosthetic devices may be attached to male or female threaded couplers, or to Morse tapers. A plurality of suture attachments facilitates attachment of soft tissue thereto.

The present invention relates to a spacer device including a sensor as well as electronic means for obtaining and transmitting the data detected by the sensor.

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.

A bone joint repair and replacement assembly. A first portion comprising a bone plate is configured to attach to a distal or proximal end of a bone proximate the joint, generally coaxially with an axis defined by the bone. A second portion comprising an articular surface is configured to attach to the first portion, generally normal with respect to the axis, and inserted into the joint. Although versions of the assembly can be configured for use with several different pivotal joints, the invention is particularly suitable for full or partial replacement of an elbow, wherein the articular surface is pivotally attached to the first portion. Another embodiment of the invention is provided to repair a fractured bone head proximate the joint, and still another embodiment of the invention is provided to repair rotator cuff-related shoulder injuries.

The system and method serves in facilitating replacement of comminuted bone fractures or portions thereof adjacent bone joints. The system and method employs a prosthesis to replace at least a portion of the comminuted bone fractures. The prosthesis serves in reproducing the articular surface of the portion or portions of the comminuted bone fractures that are replaced. In doing so, the prosthesis serves in restoring joint viability and corresponding articulation thereof.

The present disclosure generally relates to an elbow arthoplasty prosthesis that includes an ulnar component, a humeral component, one or more articulation liners, and a retention trap. The ulnar component includes a spherical bearing head that can be inserted into the humeral component in a number of orientations. The articulation liners and the retention trap are operatively engaged to the humeral component to retain the ulnar component within a humeral socket. The present disclosure also relates to methods of assembling and implanting the prosthetic device.

Methods and devices are disclosed for joint (e.g., shoulder) arthroplasty, including for reverse joint arthroplasty. In one aspect, there is provided a trial device for determining inclination, offset, and/or version of a prosthetic tray with respect to a prosthetic stem or stemless implant. In another aspect, there is provided a joint (e.g., shoulder) prosthesis, which allows for variable offset, inclination or version or any combination thereof. In another aspect, there is provided a method for setting an offset or inclination angle or a version angle or any combination thereof of a prosthetic tray with respect to a stem or stemless device implanted or to be implanted in a bone of a joint (e.g., shoulder) by matching the corresponding offset or version or inclination or any combination thereof to a trial device.

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.

A humeral implant configured for implantation at a distal end portion of a humerus. The humeral implant can be configured to articulate with a portion of an ulna. The humeral implant may include a body portion having a first end, a second end, and a side surface that extends between the first end and the second end, where the side surface includes a concave region that defines a first cross-sectional diameter that is a minimum cross-sectional diameter of the body portion.

An elbow prosthesis includes a capitellar implant having an articulating head and a stem. The articulating head includes a first passage along a first axis, a second passage along a second axis, and a receiving groove. The stem includes a proximal end and a connecting end. The connecting end includes a curved body having a bore. The curved body selectively mates with the receiving groove such that the bore axially aligns with the first axis of the first passage in an assembled position for collectively receiving a securing member. The second axis is located between the first axis and the proximal end of the stem.
