The facet joints, (or zygapophysial joints, zygapophyseal, apophyseal, or Z-joints) are a set of synovial, plane joints between the articular processes of two adjacent vertebrae. There are two facet joints in each spinal motion segment and each facet joint is innervated by the recurrent meningeal nerves.
Spinal stabilization system and method
A spinal stabilization system may include a pair of structural members coupled to at least a portion of a human vertebra with connectors. Connectors may couple structural members to spinous processes. Some embodiments of a spinal stabilization system may include fasteners that couple structural members to vertebrae. In some embodiments, a spinal stabilization system provides three points of fixation for a single vertebral level. A fastener may fixate a facet joint between adjacent vertebrae and couple a stabilization structural member to a vertebra. Connectors may couple the structural members to the spinous processes of the vertebrae. Use of a spinal stabilization system may improve the stability of a weakened or damaged portion of a spine. When used in conjunction with an implant or other device, the spinal stabilization system may immobilize vertebrae and allow for fusion of the implant or other device with vertebrae.

InactiveUS20050004634A1Stiffening the interspinous tissue structureStabilizing the vertebral columnEnemata/irrigatorsHeart valvesThermal energySpinal ligaments
Systems, apparatus, and methods for treating spinal tissue and other body structures in open and endoscopic spine surgery to relieve symptoms, such as neck or back pain. In particular, the present invention provides methods for the controlled heating of various tissues in or around the vertebral column, including various interspinous tissues, such that spinal ligaments and cartilage surrounding the vertebrae and the facet joints are shrunk or tightened to stabilize the vertebral column of a patient. Thermal energy is applied to the target tissue in a subablation mode of an electrosurgical system to cause shrinkage of the tissue, thereby stiffening the interspinous tissue and stabilizing the vertebral column. In an exemplary embodiment, a high frequency RF voltage can be applied between one or more active electrode(s) and one or more return electrode(s) to heat a target interspinous tissue to within a temperature range at which irreversible shrinkage of the tissue occurs.

Implantable thermal treatment method and apparatus
A long-term implantable ultrasound therapy system and method is provided that provides directional, focused ultrasound to localized regions of tissue within body joints, such as spinal joints. An ultrasound emitter or transducer is delivered to a location within the body associated with the joint and heats the target region of tissue associated with the joint from the location. Such locations for ultrasound transducer placement may include for example in or around the intervertebral discs, or the bony structures such as vertebral bodies or posterior vertebral elements such as facet joints. Various modes of operation provide for selective, controlled heating at different temperature ranges to provide different intended results in the target tissue, which ranges are significantly effected by pre-stressed tissues such as in-vivo intervertebral discs. In particular, treatments above 70 degrees C., and in particular 75 degrees C., are used for structural remodeling, whereas lower temperatures achieves other responses without appreciable remodeling.

Minimally invasive method and apparatus for fusing adjacent vertebrae
The present invention is a minimally invasive surgical method for fusing adjacent vertebrae. A first K-wire is inserted into the spinous process of an upper vertebrae. A second K-wire is inserted into a transverse process of a lower vertebrae. A first fixation block is secured to the first K-wire and a second fixation block is secured to the second K-wire. A rod member extends across the K-wires. A swivel block assembly is secured to achieve a desired angle for a first axis along which a first screw will be implanted into a facet joint. The swivel block assembly is secured at a desired axial position on the rod member. Percutaneous access to the upper vertebrae along the first axis is then obtained via a cannula. A removable screw having a threaded section for implantation across the facet joint and an elongated shank section that is shearable subcutaneously is inserted through the cannula. The threaded section is implanted along the first axis across the facet joint to attach the upper and lower vertebrae. A shearing tool is inserted percutaneously over the shank section and the shank section is sheared off immediately above the lamina.
