Disclosed is a prosthetic augment designed to reconstruct a lateral tuberosity shape of a humerus in a subject having proximal bone loss that includes a humeral adapter tray configured to connect a humeral liner of a reverse shoulder prosthesis to a humeral stem of the reverse shoulder prosthesis and an augment member having a first face adapted for contacting the humeral stem of the reverse shoulder prosthesis and a second face adapted for contacting an underside of a muscle, wherein at least a portion of the second face includes a bulbous surface adapted to alter a wrapping angle of the muscle around the lateral tuberosity, and wherein the second face has a radius of curvature selected from one of a constant radius of curvature or a variable radius of curvature.

An implant for shoulder arthroplasty includes a stem and optionally a head component or a cup component. The stem is sized and shaped to fit into an intramedullary canal of the humerus. The proximal portion of the stem has a concave taper and the distal portion of the stem has a taper. The distal taper includes an anterior-posterior taper and a medial-lateral taper. The shape of the stem loads the metaphysis of the humerus with a greater load than the load applied to the diaphysis of the humerus.

The invention relates to a device for producing a spacer having a stem mold (1) which has an inner space (2), wherein the inner space (2) is accessible via a proximal opening (3) and wherein the stem mold (1) has a proximal wall (4) which peripherally delimits the proximal opening (3) of the stem mold (1), a head mold (5) which has in the interior thereof a hollow space (6), wherein the hollow space (6) has a spherical surface-shaped inner surface (7) and is accessible via a distal opening (8), wherein the head mold (5) has a distal wall (9) which peripherally delimits the distal opening (8) of the head mold (5), a metal core (10) which has a stem part (12), a head part (14) and a flange (16), wherein the flange (16) projects out from the metal core (10), is arranged between the stem part (12) and the head part (14) and has a proximal surface (18) and a distal surface (20), wherein the stem mold (1) and the stem part (12) are shaped such that the stem part (12) is arranged in the inner space (2), when the proximal wall (4) is resting against the distal surface (20), and wherein the head mold (5) and the head part (14) are shaped such that the head part (14) is arranged in the hollow space (6), when the distal wall (9) is resting against the proximal surface (18).

The invention also relates to a set with such a device and to a method for producing spacers with such a device.

Joint prosthesis methods and apparatuses are provided. A bone graft blank is placed in the chamber of the bone press facing a contoured surface. The contoured surface can be part of the bone press or can comprise a surface of a patient specific negative that can be inserted into the bone press. A bone contact surface of the bone graft blank is disposed in the chamber to face the contoured surface of the patient specific insert negative. The bone contact surface of the bone graft blank is compressed against the contoured surface. The bone contact surface can be reshaped to form a patient specific bone graft.

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.

A modular humeral implant for an inverted shoulder prosthesis includes a humeral stem having, on the one hand, a diaphyseal keel of elongate shape, extending along a diaphyseal axis and shaped to be engaged in a medullary cavity of a humerus, and, on the other hand, a metaphyseal portion. A humeral spacer is mounted on the metaphyseal portion of the humeral stem and has a lower face facing the metaphyseal portion, the lower face having a peripheral portion projecting laterally from the metaphyseal portion and covered at least partially with a porous or rough metal surface coating promoting an osseointegration. A humeral insert is fastened on the humeral spacer and has a hemispherical cup shaped to receive a glenosphere of a glenoid implant.

Provided herein are rapid and effective local infection therapy methods, systems, and devices that significantly reduce the mortality, morbidity, and the cost of care in rare musculoskeletal infections. Continuous delivery of antibiotic therapy locally, at the infection site, reduces edema and provides antibiotic irrigation, significantly improving outcomes while reducing the need for systemic antibiotics.

An integral humeral stem includes a diaphyseal portion which has, orthogonal to a diaphyseal axis, an octagonal cross-section with convex rounded angles, and a metaphyseal portion in the form of a flared corolla which extends the diaphyseal portion up to a proximal face, which has, orthogonal to a central axis, an octagonal cross-section with convex rounded angles so that the humeral stem has a peripheral surface provided with eight lateral facets and eight rounded fillets which continuously extend from the diaphyseal portion to the metaphyseal portion. On the metaphyseal portion, the rounded fillets progressively widen and the lateral facets progressively narrow from the diaphyseal portion in the direction of the proximal face.

A collar arranged to couple to a prosthetic component for implantation at the end of a long bone, the prosthetic component having a distal portion arranged to couple to the bone and a proximal neck portion arranged to couple to an articulation component. The collar comprises a plate including a neck hole to receive a neck portion, such that the collar can rotate about the neck portion. The collar further comprises a plurality of attachment portions for coupling the plate to bone fragments or soft tissues. The collar is lockable to the neck portion to prevent further rotation. A prosthesis comprising a combination of a collar, a prosthetic component and an articulation component, and a surgical method of using the collar are also disclosed.

A modular reverse shoulder orthopaedic implant includes a humeral stem component and a separable fracture epiphysis component having a number of suture holes formed therein. The fracture epiphysis component is configured to receive a number of sutures for surgically repairing a proximal humeral fracture.
