According to some embodiments of the invention, an intervertebral disc replacement includes a first layer having a lower surface for contacting a first vertebral bone, a second layer coupled to the first layer, the second layer comprising a plurality of compressible column springs, and a third layer coupled to the second layer, the third layer having an upper surface for contacting a second vertebral bone. Each of the plurality of compressible column springs comprises a plurality of stacked coils, and each of the plurality of stacked coils has a spring constant (K). At least one of the plurality of compressible column springs includes a first coil having a first spring constant and a second coil comprising a second spring constant, wherein the first spring constant is different from the second spring constant.

The invention relates to a glenoid (shoulder socket) implant prosthesis, a humeral implant prosthesis, devices for implanting glenoid and humeral implant prostheses, and less invasive methods of their use for the treatment of an injured or damaged shoulder.

Assemblies of one or more implant structures make possible the achievement of diverse interventions involving the fusion and/or stabilization of the SI-joint and/or lumbar and sacral vertebra in a non-invasive manner, with minimal incision, and without the necessitating the removing the intervertebral disc. The representative lumbar spine interventions, which can be performed on adults or children, include, but are not limited to, SI-joint fusion or fixation; lumbar interbody fusion; translaminar lumbar fusion; lumbar facet fusion; trans-iliac lumbar fusion; and the stabilization of a spondylolisthesis.

An orthopedic device for implanting between adjacent vertebrae comprising: an arcuate balloon and a hardenable material within said balloon. In some embodiments, the balloon has a footprint that substantially corresponds to a perimeter of a vertebral endplate. An inflatable device is inserted through a cannula into an intervertebral space and oriented so that, upon expansion, a natural angle between vertebrae will be at least partially restored. At least one component selected from the group consisting of a load-bearing component and an osteobiologic component is directed into the inflatable device through a fluid communication means.

An intervertebral implant includes a body and a plate. The body has an upper surface defining an upper plane and a lower surface defining a lower plane. First and second fastener holes of the plate are configured to retain the heads of first and second fasteners. A portion of each of the shanks of the first and second fasteners extends from the first and second fastener holes beyond the upper plane. The shank portions of the first and second fasteners are curved in a direction away from the upper surface. The third fastener hole is configured to retain the head of the third fastener between the upper and lower planes. A portion of the shank of the third fastener extends from the third fastener hole beyond the lower plane. The shank portion of the third fastener is curved in a direction away from the lower surface.

An intervertebral implant includes a core member operably coupled between an upper and a lower base member. An outer cavity extends between the core member upper end and lower end, and radially between the inner cavity and an outer surface of the core member. A core member inner wall is formed between the inner and an outer cavity, and a core member outer wall is formed between the outer cavity and the outer surface of the core member. A first locking member is positioned on at least one of the core member upper end and the core member lower end and at least one second locking member is positioned on an inner surface of at least one of the upper and lower base member for locking engagement. The upper and lower end of the core member are oriented at a lordotic angle ranging from 1 degrees to 20 degrees.

A device, system, and method for performing a spinal procedure. The device includes first and second shape-memory outer platforms, the outer platforms expanding at a temperature greater than the transformative temperature, a core member having first and second expansion bodies and first and second wedge members, the first expansion body being coupled to the first outer platform and the second expansion body being coupled to the second outer platform, and a screw rotatably disposed within the core member, the screw passing through at least a portion of each of the first and second wedge members. Rotation of the screw causes the first and second wedge members to move toward each other and the first and second expansion bodies to move away from each other. Thus, reaching a transformation temperature and rotating the screw expands the device to come in contact with and anchored against both of the adjacent vertebrae.

A spinal facet fusion implant comprising: an elongated body having a distal end, a proximal end and a longitudinal axis extending between the distal end and the proximal end, the elongated body being characterized by a superior body surface and an inferior body surface; a superior stabilizer extending outwardly from the superior body surface, the superior stabilizer being characterized by a superior stabilizer surface; and an inferior stabilizer extending outwardly from the inferior body surface, the inferior stabilizer being characterized by an inferior stabilizer surface; wherein (i) the superior body surface and the inferior body surface are tapered relative to one another, and/or (ii) the superior stabilizer surface and the inferior stabilizer surface are tapered relative to one another.

The invention features a glenoid (shoulder socket) implant prosthesis, a humeral implant prosthesis, devices for implanting glenoid and humeral implant prostheses, and less invasive methods of their use for the treatment of an injured or damaged shoulder.
