摘要:
Systems for spinal stabilization and fixation replace, reconstruct or augment the spinal ligamentous and/or bony tissues resected during surgical procedures. The spinal stabilization system includes at least an implant configured to span the intervertebral disc space with at least one of its ends attached to a respective vertebral body by at least one anchor. The system has a low profile conformable to the spinal anatomy.
摘要:
Allogenic or xenogenic materials are used to provide intervertebral disc nucleus implants and/or annular plugs. The allogenic or xenogenic materials comprise natural disc annulus material, which may have a portion of the anterior longitudinal ligament attached. The tissue may be used “as is” without an additional core or covering, or it may be used in combination with other materials. The material may be rolled, folded, layered and/or sutured, stapled, or glued to provide a solid plug of natural biological material. The implant may be provided as a dehydrated, substantially rod-shaped segment having a diameter less than the diameter of the hydrated material, and may have one or more ends of the dehydrated rod terminate with a further reduced diameter portion, preferably a point.

The present application discloses various embodiments of surgical fasteners that combine mechanical and osteogenic means of fixation to maximize in vivo stability and long-term performance. The fastener generally includes a head and a shaft. The fastener is fenestrated and includes a channel that leads into one or more openings along the shaft. Bone void filling materials is delivered through the channel to the shaft to improve anchoring. In one embodiment, the osteogenic means comprise a coating applied to the fastener to improve bony apposition. The fastener with combined mechanical and osteogenic means provides initial, immediate anchoring and long term anchoring.

The invention provides devices and related methods and composition useful for diagnosis and monitoring the pain generator(s) of axial pain with or without radiculopathy and methods for screening test compounds potentially useful for treating axial pain with or without radiculopathy. Alternatively, degenerated discs can be monitored and treated before occurrence of a pathological pain condition. Pain markers and markers of degenerating disc include markers of neuronal, vascular, immune and matrix elements.
摘要:
Devices and methods for spinal stabilization include first and second anchor assemblies engageable to respective ones of first and second vertebrae and a connecting element engageable to the first and second anchor assemblies. The connecting element includes opposite first and second end members and a bumper assembly between the end members that flexibly connects the end members so the connecting element can provide dynamic stabilization of the spinal column when engaged to the anchor assemblies.
摘要:
A system for controlling a nucleus pulposus augmentation procedure for an intervertebral disc comprises a powered actuation device and a control device for controlling an operating parameter of the actuation device. The system further comprises a space creating instrument including a spacing portion for forming a space within the nucleus pulposus of the intervertebral disc and a delivery instrument for delivering a material to the space. The space creating instrument is activated by the powered actuation device to expand the spacing portion with the material to create the space within the nucleus pulposus of the intervertebral disc.
