An intervertebral disc for placement between adjacent vertebrae comprising: an anterior side; a posterior side; a first lateral side; a second lateral side; an upper endplate having an inner surface and an outer surface, wherein the outer surface of the upper endplate is adapted for contacting a first vertebra; a lower endplate having an inner surface and an outer surface, wherein the outer surface of the lower endplate is adapted for contacting a second vertebra; and an elastic membrane extending from the inner surface of the upper endplate to the inner surface of the lower endplate and defining an inner volume that is at least partially filled with a fluid, wherein the elastic membrane is affixed to the inner surface of the upper endplate and to the inner surface of the lower endplate.

Artificial intervertebral disc implant

The present invention relates to an expandable prosthetic implant device for engagement between vertebrae generally comprising an inner member, outer member, and gear member positioned coaxial with respect to each other such that the inner and outer members are moveable relative to each other along an axis. The gear member is axially fixed to the outer member and freely rotatable with respect to the outer member and the gear member threadedly engages a threaded portion of the inner member to translate inner member along the axis. The implant is configured to engage the vertebrae in a predetermined alignment and the gear member includes gear teeth exposed to the exterior and configured to be accessible by a tool member at a plurality of angular positions around the perimeter of the implant device.

Expandable vertebral prosthesis

The present invention relates generally to a prosthetic spinal disc for replacing a damaged disc between two vertebrae of a spine. The present invention also relates to a method for implanting a prosthetic spinal disc via anterior or anterior lateral implantation. Other surgical approaches for implanting the prosthetic disc may also be used.

Anterior prosthetic spinal disc replacement

The present invention relates generally to a prosthetic spinal disc for replacing a damaged disc between two vertebrae of a spine. The present invention also relates to a method for implanting a prosthetic spinal disc via posterior or posterior lateral implantation. Other surgical approaches for implanting the prosthetic disc may also be used. The present invention also involves a method for implanting the prosthetic spinal disc while either avoiding or minimizing contact with the spinal cord and nerve rootlets, or reducing the time and extent that they need to be repositioned during implantation.

Posterior prosthetic spinal disc replacement and methods thereof

Interspinous process implants are disclosed. Also disclosed are systems and kits including such implants, methods of inserting such implants, and methods of alleviating pain or discomfort associated with the spinal column.

Spinous process spacer

Selectively demineralized bone-derived implants are provided. In one embodiment, a bone sheet for implantation includes a demineralized field surrounding mineralized regions. In another embodiment, a bone defect filler includes a demineralized cancellous bone section in a first geometry. The first geometry is compressible and dryable to a second geometry smaller than the first geometry, and the second geometry is expandable and rehydratable to a third geometry larger than the second geometry.

Demineralized bone-derived implants

Prosthetic spinal disc replacement

Demineralized bone implants

The invention relates to an artificial intervertebral disc for placement between adjacent vertebrae. The artificial intervertebral disc is preferably designed to restore disc height and natural disc curvature, allow for a natural range of motion, absorb shock and provide resistance to motion and axial compression. Furthermore, the intervertebral disc may be used in the cervical, the thoracic, or the lumbar regions of the spine. The artificial intervertebral disc may include either singularly or in combination: an interior including at least one spring member preferably incorporating a arcuate surface member, a flexible core, the flexible core preferably being a slotted core, a ring spring, a winged leaf spring, or a leaf spring, or The articulating member preferably being attached to one of the endplate by an intermediate shock absorbing element.

Controlled artificial intervertebral disc implant

Skeletal reconstruction cages include a central body having first and second ends, a first end cap coupled to one end of the central body, and a second end cap coupled to the other end of the central body. At least two of the central body, first end cap, and second end cap are formed from bone. Each of the central body, first end cap, and second end cap may be provided in different sizes so that cages with varying overall heights, and related angulations, may be created.

Skeletal reconstruction cages

The present invention relates to an implant comprising two or more bone fragments that are combined to form a single unit. Cancellous bone or cortical bone is removed from a source and fashioned into bone components with desirable shapes and sizes. The bone components may be integrated to form implants for implantation in the body. Bone stock may be formed by combining sections of various bones of the body, and the bone stock may be further fashioned for use as implants with particular geometries.

Multipiece implants formed of bone material

A bone fusion implant for repair or replacement of bone includes a hollow body formed from at least two bone fragments which are configured and dimensioned for mutual engagement and which are coupled together. The hollow body may be formed of autograft, allograft, or xenograft bone tissue, and may include a core formed of at least one of bone material and bone inducing substances, with the core being disposed in the hollow body.
