The present disclosure provides a bone-implantable device and methods of use. The bone-implantable device comprises a body having an exterior surface, wherein a portion of the exterior surface includes a cured osteostimulative material comprising MgO.

A device configured for use as a medical implant is disclosed herein. The device includes an anchor body having a perimeter wall defining a rim, and a cavity dimensioned to receive an elastic articulating component. At least one lattice region is arranged at least along an inner surface of the perimeter wall adjacent to the rim. An elastic articulating component is configured to fill the cavity and attach to the at least one lattice region.

Prostheses are described for stabilizing dysfunctional sacroiliac (SI) joints. The prostheses are sized and configured to be press-fit into surgically created pilot SI joint openings in dysfunctional SI joint structures. The prostheses have a pontoon shape with opposed elongated partially cylindrical sections connected by a bridge section. The partially cylindrical sections and, in some instances, the bridge section have a porous structure.

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, the fossa 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 bone-interfacing surfaces are anatomically-contoured to their respective bone surfaces and formed with materials and textures which promote osseointegration with the joint replacement.

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.

A bellows shaped spinal implant, comprising an upper plate having an upper opening therethrough, a lower plate having a lower opening therethrough, and aa bellows shaped shell extending between and joining the upper plate and the lower plate. The bellows shaped shell is formed of titanium or an alloy comprising titanium and includes a wall extending continuously therearound that defines a hollow interior in communication with the upper opening and the lower opening. The wall has a thickness in the range of 0.5 mm to 1.0 mm to provide for radiographic imaging through the wall. The wall is angled or curved inwardly or outwardly between the upper plate and the lower plate to provide stiffness that mimics the stiffness properties of a similarly sized polyetheretherketone (PEEK) implant.

In one embodiment, an intervertebral implant includes a body and a locking element. The body includes a leading surface and a trailing surface opposite the leading surface. The body also includes first and second bone fastener passageways through the implant body and a cavity in between the first and second passageways. The cavity includes a trailing wall that separates the cavity from the trailing surface. The locking element is disposed in the cavity such that part of the locking element is visible through an access opening in the trailing wall so that the locking element may be rotated from outside of the implant. In a first rotational position, a first part of the locking element is located within one of the first and second passageways and in a second rotational position, the first part of the locking element is inside the body covered by the trailing wall.

Modular endoprosthesis for at least partial replacement of a tubular bone, comprising, as module components, a stem for insertion into a bone cavity of the tubular bone, and an end piece comprising a support body with a neck part arranged on the medial aspect thereof. Said module components being able to be coupled to each other and released from each other along a longitudinal axis of the shaft. The end piece has at least two different surface configurations on its support body, namely a closed surface (6′) on a medial aspect, and a porous configuration of the surface on the opposite, lateral aspect. The latter permits and positions the adhesion of muscle tissue, specifically without suturing. The muscle trauma caused by suturing, and the peak loads that occur at the respective suture points, can thus be avoided by virtue of the invention, by means of the location-specific direct adhesion of the muscle. It is thus possible to achieve quicker and reliable mobilization of the patient, and this with a reduced risk of complications.

Provided is a prosthesis for ankle arthroplasty including a talar dome component configured to be attached to a talus bone. Also provided is a guide instrument for guiding a reamer to prepare a talus to receive the talar dome component.

A spinal implant is provided including an upper surface, a lower surface, a front surface and a back surface, two side surfaces extending between the upper surface and the lower surface, the two side surfaces extending between the front surface and the back surface and an opening positioned closer to the back surface than the front surface. The opening is provided to contain graft material that spans between a cortical rim of the upper vertebral body and the cortical rim of the lower vertebral body. The method includes packing the opening with graft material, wherein the graft, material spans between the decorticated cortical rim of the upper vertebral body and the decorticated cortical rim of the lower vertebral body.
