Abstract: Flexible spinal stabilization apparatuses are provided. The apparatuses include a flexible support element configured to be attached to a first vertebra and a second vertebra. The apparatuses also include a bone growth promoter coupled to the flexible support element. The flexible support element spans one or more intervertebral spaces but the bone growth promoter does not.

Abstract: A medical apparatus for use proximate a surgery location on a spine of a subject includes a first lateral support member and a second lateral support member, each lateral support member coupled to a portion of the spine proximate a first vertebra. A transverse connection member has a first end, a second end, and an intermediate portion therebetween, with the first end coupled to the first lateral support member and the second end coupled to the second lateral support member. A first extension member has a first end and a second end, with the first end coupled to the intermediate portion of the transverse connection member, and the second end coupled to a spinous process of a second vertebra.

Abstract: Catheter devices for diagnosing and treating discogenic pain are provided. The catheter devices comprise a tubular body configured for insertion into an intervertebral disc and a pressure measuring device disposed along the length of the tubular body, the pressure measuring device configured to measure the pressure within the intervertebral disc. The catheter devices are capable of measuring the pressure within an intervertebral disc of a subject while the subject is moving.

Abstract: Medical apparatuses for restricting the motion of a vertebra relative to another vertebra and methods for using the apparatuses are provided herein. The medical apparatuses comprise a flexible element having two ends and a connector capable of securing the ends of the flexible element to a first vertebra disposed above or below a second vertebra or to a spinal device. The flexible element is disposed across at least a portion of one or more vertebral elements of the second vertebra and is tensioned to restrict the motion of the second vertebra relative to the first vertebra.

Abstract: Spinal stabilizing elements and spinal stabilization systems composed of spinal stabilizing elements in combination with disc prostheses or disc nucleus replacements are provided. The stabilizing elements and stabilization systems are designed to preserve the natural mobility of vertebral discs and facet joints in patients with facet joint disease or patients who has undergone a prior destabilizing procedure, such as a facetectomy. The stabilizing elements may be pivoting elements or dynamic elements.

Abstract: A device including a side wall defining an inner space; a lock mechanism; a pivot post; and a securement post where the device is a facet joint fusion cage; and a facet joint distractor is capable of engaging the lock mechanism via a lock and key arrangement. A method of using such a device includes positioning the facet fusion cage in the facet joint of a patient in need of facet joint fusion; and moving the securement post to a locked position.

Abstract: Intervertebral disc prostheses are provided. More particularly, the invention provides disc prostheses that have adjustable disc heights, that are readily converted into fusion prostheses and that provide a range of motions that effectively mimic the natural range of motions of a spinal disc.

Abstract: Bone anchoring devices for anchoring medical devices to bones and for reducing bone fractures are provided. The devices include a bone anchor portion designed to allow for bony ingrowth and secure fixation to a bone and an internal fastener designed to resist bony ingrowth and facility easy removal of the fastener from a patient.

Abstract: A medical apparatus for alleviating the symptoms associated with spinal stenosis have a body including first and second supports disposed along the length of the body. The first support is configured to accommodate at least a portion of a vertebral component of a first vertebra disposed above or below a second vertebra. The second support is configured to accommodate at least a portion of a vertebral component of the second vertebra. The distance between the supports is sufficient to increase the space between the first vertebra and the second vertebra. Methods for using the apparatus include implanting the apparatus into a subject.
