A beam acts as an implantable spinal support structure. The beam is generally cylindrical in form with two semi-cylindrical shells defining a cylindrical contour of the beam and with a web passing through a central axis of the beam and joining midpoints of the two shells together. The shells preferably have threads on an outer surface thereof to engage bone within a cylindrical hole passing through two adjacent vertebrae spanning a disk space, for support of the vertebrae such as for fusion thereof together. One end of the beam can be tapered to maximize structural support for the vertebrae. This tapered end can be provided as a separate extension removably attachable to other portions of the beam in one embodiment. A method for implantation is also disclosed where the beam is implanted at an angle to the spinal axis and intersecting a disk space between adjacent vertebrae.

The fusion device for fusing a synovial joint of a human or animal patient, in particular a human facet joint, finger joint or toe joint, includes two pin-shaped anchorage portions and arranged therebetween a stabilization portion. The anchorage portions include a thermoplastic material which is liquefiable by mechanical vibration. The stabilization portion preferably has a surface which is equipped for enhancing osseointegration. The anchorage portions have a greater thickness and a greater depth than the stabilization portion. Then the fusion device is pushed between the articular surfaces and mechanical vibration, in particular ultrasonic vibration, is applied to the proximal face of the fusion device. Thereby the liquefiable material is liquefied where in contact with the bone tissue and penetrates into the bone tissue, where after re-solidification it constitutes a positive fit connection between the fusion device and the bone tissue.

This set (J) comprises glenoid components (S1, S2, M1, M2, L1, L2) that each include a body (S1.1, S2.1, M1.1, M2.1, L1.1, L2.1) defining, on two of its opposite faces, respectively, a joint surface (S1.2, S2.2, M1.2, M2.2, L1.2, L2.2), intended to cooperate with a humeral head, and a bearing surface (S1.3, S2.3, M1.3, M2.3, L1.3, L2.3) bearing against the socket of a shoulder blade. In this set, the glenoid components are provided in several different sizes (S, M, L), respectively defined by the dimensions of the joint surface of their body. At least two glenoid components (S1 and S2, M1 and M2, L1 and L2) of which the bearing surfaces (S1.3 and S2.3, M1.3 and M2.3, L1.3 and L2.3) respectively have different dimensional geometries are provided so as to allow the surgeon to improve the durability of the mechanical cooperation between the implanted component and the operated socket.

A prosthetic intervertebral disc is formed of first and second end plates sized and shaped to fit within an intervertebral space and to be implanted from the back of the patient, thereby decreasing the invasiveness of the procedure. The posterior approach provides for a smaller posterior surgical incision and avoids important blood vessels located anterior to the spine particularly for lumbar disc replacements. The first and second plates are each formed of first, second and third parts are arranged in a first configuration in which the parts are axially aligned to form a low profile device appropriate for insertion through the small opening available in the TLIF or PLIF approaches described above. The three parts of both of the plates rotate and translate with respect to one another in situ to a second configuration or a deployed configuration in which the parts are axially unaligned with each other to provide a maximum coverage of the vertebral end plates for a minimum of insertion profile. Upon deployment of the disc, a height of the disc is increased.

Implants for positioning between vertebral members. The implant may include a superior surface to contact against a first vertebral member, and an inferior surface to contact against a second vertebral member. The implant may include a central web that extends between first and second flanges. The flanges may be shaped to form gaps that extend the height of the implant. Spaces in communication with the gaps may be formed in an interior of the implant to hold bone growth material.

A surgical instrument and method for inserting a spinal implant in the intervertebral disc space between two adjacent vertebrae and an anchor engageable with the implant and an adjacent vertebra are provided. The instrument includes an inserter having an engagement portion including a distal engagement surface for interfacing with the implant and a handle portion. The engagement portion includes a track for slidably translating the anchor toward the engagement surface. A kit is provided including the inserter and a tamp to force the anchor into engagement with the implant and the adjacent vertebra. The kit may also include a cutter for piercing the adjacent vertebra.

A prosthetic device for replacing at least part of one vertebral body, the prosthetic device being expandable from a fully collapsed state to a fully expanded state and comprising an upper endplate, a lower endplate and an expandable support structure extending between the two endplates, said expandable support structure being configured to displace the two endplates relative to one another along a longitudinal axis of the prosthetic device and to hold the two endplates at a minimum axial distance that corresponds to the height of at least one intervertebral disc and half a vertebral body, wherein the expandable support structure includes an anterior post and a posterior post, wherein the length (L1/L2) of each post is individually adjustable and is lockable independently from one another to hold the two endplates with an inclination of 0 to 40 relative to each other.

A four-component artificial intervertebral disc may provide six degrees of movement: flexion, extension, lateral bending, axial rotation, axial deflection, and anterior/posterior translation. The disc may include a superior endplate, a superior core, an inferior core, and an inferior endplate. The superior endplate may include a concave mating surface, and the inferior endplate may include a spherical mating surface. The superior endplate may roll across the superior core to provide flexion, extension, and lateral bending. The superior endplate may twist or rotate atop the superior core to provide axial rotation, and the superior endplate may slide over the superior core to provide anterior/posterior translation. The superior core may be connected to the inferior core, and the inferior core may be connected to the inferior endplate. The inferior core may be made from a flexible material that may enable the artificial disc to expand or compress vertically.

Systems and methods for treating musculoskeletal disorders of the spinopelvic anatomy including treating spinal deformities by spinopelvic fixation including fusion of the sacroiliac joint at the base of long spinal fusion construct cases. The system may include implants designed to be used as an adjunct to long spinal fusions to further the immobilization and stabilization of the sacroiliac joint. The implants may be designed to augment an S2AI screw and an S1 screw in order to improve durability of the foundation of the spinal construct. The implants may have a triangular cross section.

A method for treating a spine is provided. The method includes the steps of: disposing an interbody implant adjacent a posterior portion of an intervertebral disc space; connecting a surgical instrument with at least one fixation element fastened with tissue adjacent the posterior portion; and manipulating the surgical instrument such that tissue adjacent the posterior portion engages the interbody implant and one or more vertebra rotate about the interbody implant. Spinal implants; surgical instruments and systems are disclosed.
