Spinal prothesis brantigan cages

Theoretically, a rectangular geometry should allow for more surface area between the cage and the vertebral endplate, which in turn should decrease the force per unit area on the vertebral endplate. The invention includes wedge shaped plugs or blocks for restoring normal spinal alignment especially in the lower lumbar levels.

Interbody Cages for Spine Fusion

This article is an orphanas no other articles link to it. The implants are preferably made of a radiolucent material such as carbon fiber reinforced polymer such as PEEK polyetherether ketone or Ultrapek polyether ketone ether ketone ketone. The spinal fusion implant of claim 23, wherein said protrusion comprises a ridge.

For the surgeon treating this pathology, the ideal Spinal prothesis brantigan cages is to restore to degenerative motion segment and its spinal canal to their normal spatial relationship while assuring their normal functional movement and weight bearing capabilities.

The apparatus of claim 10 wherein at least one of the components has a roughened surface for engaging the end plates of the patient's vertebral bodies. The apparatus 10 includes a two part cage body 15 having upper and lower cage sections 16, The current invention improves the reliability and precision of this procedure.

Haid Jr; Kevin T. The Ray implant is defective and unworkable in that it is incapable of being used in the manner in which it is described as it is not possible to insert into hard bone an isolated helical coil without any wall members to support such a coil, which coil would be analogous structurally to a slinky.

These passageways allow for packing with bone-inducing-growth material that allows the cage 15 to become part of the fusion. This bone graft material is also packed between and beside the plugs and around the plugs in the disc space between the vertebrae.

Interbody fusion cage

Typical heights for the anterior ends of the plug are 11 to 15 mm in three sizes of 11, 13 or 15 mm. When something goes wrong with the spinal functions, the openings often pinch the nerve extending therethrough, causing a great deal of pain.

Typical teeth or serrations projecting from the weight Spinal prothesis brantigan cages surfaces will have heights of 0. My prior aforesaid U. The following table lists the parts numbers and parts descriptions as used herein and in the drawings attached hereto.

The spinal fusion implant of claim 43, wherein said implantation material is porous. The spinal fusion implant of claim 16, wherein said implant having said at least one end providing access to said hollow interior is in combination with a cap adapted to close said hollow interior.

The spinal fusion implant of the present invention is easier to use as it occupies less space, does not require pre-tapping, and can be inserted without the need to rotate an instrument within the closed confines of the spinal wound. The tops and bottoms 11a of the plug are continuous and unslotted with traverse teeth or serrations 19 thereacross.

Combined, this structure functions as protection of the spinal cord, bears the load of the body and can bend. As regards this method of performing interbody spinal fusion using essentially cylindrical threaded implants, a special problem arises see FIG.The present invention provides a device and methodology for use in spinal fusion surgeries.

An implant is proved for forming a rigid structure between adjoining vertebrae in a patient. The implant is a cage defined by at least a first end, second end, first side, and second side surface, wherein first and second side surfaces extend substantially parallel to each other to span a space between.

Sep 26,  · Prosthetic implant for intervertebral spinal fusion: June, Brantigan: / Anterior interbody fusion device Surgically implanting threaded fusion cages between adjacent low-back vertebrae by an anterior approach while the spinal fusion implants 14a and 14b will not protrude from the sides of the spinal.

A cage for use in a spinal repair system wherein a pair of inert, relatively open bone-graft contouring cages are disposed between adjacent vertebrae mounted to the boney structure of these vertebrae wherein the vertebrae will knit together and act as a single unit.

The upper and lower surfaces of the cages follow an arcuate path for increased. Togawa D, Bauer T, Brantigan JW, Lowery GL () Bone graft incorporation in radiographically successful human intervertebral body fusion cages. Spine – CrossRef PubMed Google Scholar A61F2/ — Joints for the spine, e.g.

vertebrae, spinal discs for the fusion of spinal bodies, e.g. intervertebral fusion of adjacent spinal bodies, e.g. fusion cages substantially parallelepipedal, e.g. having a rectangular or trapezoidal cross-section.

Animal models for spinal fusion are essential for preclinical testing of new fusion methods and adjuncts. They allow for control of individual variables and quantification of outcome measures.
