The present invention provides an implant for reconstructing an acetabulum and at least part of a pelvic structure. To this end, the implant comprises a frame structure embodied by at least one first profile element for transferring joint forces, a joint section which forms at least part of an artificial acetabulum, at least two attachment sections for attaching the implant to bone tissue, wherein a first attachment section is provided for attachment to a sacral bone or iliac bone and a second attachment section is provided for attachment to a pubic bone, and at least one plate element for supporting internal organs, which is surrounded by the frame structure, at least in sections.

A system for fixing a prosthetic component to an anchor implanted in the bone of a patient. The prosthetic component includes a fixing channel and an installation channel. The fixing channel opens to an engagement collar configured to engage with a bone anchor. The installation channel opens from an outer surface of the prosthetic and communicates with the fixing channel. The installation channel permits placement of a fastener therethrough into the fixing channel to secure the prosthetic to the bone anchor. The axes of the fixing channel and the installation channel intersect at a point which lies within the radius of a fastener seat which is configured to engage a head of the fastener when the fastener is placed into the fixing channel.

An orthopaedic fixation assembly for prosthetic biologic attachment. The orthopaedic fixation assembly may include a main body with a longitudinally-extending stem having a proximal end, a distal end, and a cavity body. An anchor plug may be configured to be received within the stem cavity, and securable thereto via complementary mating surfaces. A spindle structure may be fixedly attached to the proximal end of the longitudinally-extending stem and protrude outwardly therefrom such that a portion of the structure extends externally beyond the resected cavity of the bone that may prevent rotational motion of the spindle. The spindle structure may have at least one compliant biasing member configured to apply a compressive force to the surrounding bone. A porous coating may be at the juncture between stem and spindle structure, on the spindle, and the splines and anti-rotation chocks, improving the initial stability of the implant and facilitating long-term bone ingrowth.

A system includes a constrained acetabular insert, a dual mobility liner, and a femoral head. The constrained acetabular insert has its perimeter extending beyond hemisphere and the dual mobility liner has its perimeter extending beyond hemisphere and configured to tilt and rotate within the constrained acetabular insert. The femoral head is configured to tilt and rotate within the dual mobility liner. The constrained acetabular insert may include a plurality of tabs and the dual mobility liner may include screw threads for receiving the plurality of tabs.

An orthopaedic knee prosthesis includes a femoral component having a condyle surface. The condyle surface is defined by one or more radii of curvatures, which are controlled to reduce or delay the onset of anterior translation of the femoral component relative to a tibial bearing.

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.

An intervertebral disc implant for use in the spine including a first part and a second part, wherein the first part and second part are configured as a joint prosthesis for the spine. The first part includes one of a concave or convex articulating surface and the second part includes one of the other concave or convex articulating surface. One of the concave or convex articulating surfaces is preferably elliptically shaped in at least one direction and does not match and is different than one of the other concave or convex articulating surfaces.

Representative embodiments are disclosed for a spinal disc device which is implantable between adjacent vertebral bodies. A representative spinal disc device comprises: a first transverse plate member; a first arcuate extension extending longitudinally from the first transverse plate member and having a first configuration; a second transverse plate member; and a second arcuate extension extending longitudinally from the second transverse plate member and having a second, mating configuration with the first configuration of the first arcuate extension and slideably moveable with respect to the first arcuate extension, with the first and second arcuate extensions further arranged to form a central through-channel between the first and second transverse plate members to hold bone graft material. In various embodiments, the first and second configurations of the first and second arcuate extensions are each a partially spherical, convex shell configuration providing for movement in both the sagittal and coronal planes for deformity correction.

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.

In some embodiments, a revision implant includes a body extending between a first planar surface and a second planar surface and a head extending from the first planar surface of the body. The head is configured to couple the revision implant to at least one additional component of a multi-component prosthesis. At least one coupling mechanism is configured to couple the body to a first bone.
