An intervertebral prosthesis for insertion between adjacent vertebrae includes upper and lower prosthesis plates locatable against respective vertebrae and having opposing concavely curved recesses therein, and a core located between the plates. The core has opposed, convexly curved surfaces received in the recesses of the plates to allow the plates to slide in articulated manner over the core. The opposed surfaces of the core and the recesses of the plates have cooperating spherical curvatures. The recess of each plate surrounds a locating peg projecting centrally from the base of the recess and is bounded by an annular rim, such that the annular rims of the plates are arranged to contact one another at a predetermined limit of sliding movement of the plates over the core. The peg locates loosely in an opening located centrally in a curved surface of the core, whereby the plates can slide over the core in all directions while the peg holds the core captive.

The present application is generally directed to implantable systems, devices and related methods pertaining to spinal surgery. In particular, the present application discloses a frame and spacer system for inserting into a disc space. The frame and spacer system is of low profile. The frame can receive different fixation devices, including threaded and non-threaded fixation devices.

A bellows shaped spinal implant, comprising an upper plate, a lower plate and a bellows shaped shell extending between and joining the upper and lower plates. The bellows shaped shell is formed of titanium or an alloy comprising titanium and includes a wall extending therearound that defines a hollow interior. 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 and lower plates to provide stiffness mimicking the stiffness properties of a similarly sized polyetheretherketone (PEEK) implant. The upper and lower plates each comprise porous contact regions including a three-dimensional gyroid lattice structure defined by a plurality of struts and pores in communication with the hollow interior. The outer surfaces of at least a portion of the struts may comprise a laser ablated textured surface.

A prosthesis for implantation in a de-nucleated intervertebral disc includes a fiber ring-like layer which encloses a polymeric layer to create an annular space. The annular space is inflatable with an in-situ curable liquid polymer and forms an interior cavity. The annular space may be expanded uniformly or differentially to be tailored to the needs of a particular vertebral segment and to achieve optimal disc space width and angle, thereby stabilizing the segment while preserving normal motion of the vertebral segment. The interior cavity provides a void that allows inward deformation of the implant during weight bearing activities and bending. The prosthesis can be elastically deformed through axial elongation to a reduced profile to load into a delivery cannula using pulling techniques.

Provided is a glenoid implant system that includes a tray component that includes a bone-facing surface and a bearing-facing surface on opposite side of the bone-facing surface; and a bearing component that includes an articulating surface that is generally concave and a back side on opposite side of the articulating surface that is generally convex, wherein the articulating surface is configured for engaging a convex humeral head and the back side is configured for engaging the bearing-facing surface of the tray component thus enabling the bearing component to slide about on the tray component while the convex humeral head articulates against the articulating surface.

An implant having a joint facing surface and a bone facing surface forming a body member and a dorsal member therebetween. The implant further having a ring member extending out from the bone facing surface to a free end disposed for insertion into a bone recess. The body member and the dorsal member include a concave curvature on the bone facing surface and a convex curvature on the joint facing surface.

An intervertebral spinal spacer system includes a first portion of a modular spacer, the first portion having an upper surface, a lower surface, and an outer surface, and a second portion of the modular spacer, the second portion having an upper surface a lower surface, and an outer surface. The first portion is selectively engageable with the second portion. The first portion and the second portion each define an internal cavity extending from the respective upper surface to the respective lower surface.

Techniques for implantable orthopedic pain management devices are disclosed, including incising an opening in a synovial capsule substantially surrounding a joint, using a first tool to form an enlarged opening in the synovial capsule, determining whether to modify the joint, the joint being modified using a second tool if a bone structure coupled to one or more bones is found within the joint and the bone structure is configured to limit articulation of the one or more bones when an implantable device is inserted into the synovial capsule and the joint, and inserting the implantable device into the synovial capsule through the enlarged opening, the implantable device being inserted into the joint using a third tool.

The present invention relates generally to a prosthetic spinal disc for replacing a damaged disc between two vertebrae of a spine and methods for inserting said discs. The intervertebral prosthetic discs are provided with connections for facilitating implantation and removal and features which enhance primary and secondary stability over time.
