Abstract: The present invention describes methods for treating a degenerative intervertebral disc disorder comprising implanting a disc stabilization device into a subject and administering at least one therapeutic agent which promotes healing of the disc to the subject. The invention also includes methods of promoting healing of damaged or degenerated intervertebral discs comprising decreasing the load of the disc through a disc stabilization device and inhibiting the inflammatory process. Also described are hydrogels for use in combination with extradiscal stabilization devices, as intradiscal stabilization devices, as drug carriers, and as combinations thereof.

Abstract: An instrument for use in a procedure for inserting a spinal implant between human vertebrae may include a shaft and an end member. The end member may rotate with respect to the shaft. An angle of the end member with respect to the shaft may be varied when the end member is in a disc space between the human vertebrae. The instrument may include a slide for securing the end member at selected angles relative to the shaft. The end member may be separable from the shaft when the end member is in a selected orientation with the shaft. An instrument kit may include a shaft assembly and modular end members for various steps in a surgical procedure, such as disc space preparation, disc space evaluation, and spinal implant insertion.

Abstract: The present invention provides a sensitive test for objectively diagnosing the presence of cancerous cells in samples of human tissue, fluids, or semi-fluids, such as feces. The detection method employs the detection of transcripts for stromelysin-3 in human cells. A reverse transcriptase-polymerase chain reaction is utilized so that cancer can be detected in very small samples.
