    摘要： An implant system for implantation between adjacent spinous processes for the relief of pain associated with the spine. The implant has a series of spacers which may be inserted over a shaft located between adjacent spinous processes thus allowing the implant to be assembled in situ. The spacers may rotate on the shaft relative to the wings. To minimize trauma to the patient, each spacer has a tapered tissue expander to distract the opening between the spinous processes during assembly. The shaft is connected to a wing, and a second wing or deployable wing may be inserted over the shaft and locked into place.

    摘要： A bone anchor which has thread characteristics on the distal shaft adjacent the tip suitable for engaging bone cement and different thread characteristics on the proximal shaft adjacent the head suitable to engage and secure the anchor to natural cancellous and cortical bone. The thread on the distal shaft is designed to engage and secure the anchor to bone cement embedded within the bone without fracture of the bone cement. In particular embodiments, the distal shaft bears two threads which merge to form a single proximal thread on the proximal shaft, the distal threads having half the pitch of the proximal thread.

    摘要： An adaptive spinal rod is provided for connecting levels of an adaptive stabilization system to support the spine while providing for the preservation of spinal motion. Embodiments of the adaptive stabilization rod include a ball having an anchor system, a deflection system, a vertical rod system and a connection system. The deflection system provides adaptive stabilization and load-sharing. The adaptive spinal rod connects different levels of the construct in a multilevel construct. The adaptive spinal rod cooperates with the deflection system to further reduce stress exerted upon the bone anchors and spinal anatomy.

    摘要： Systems and method in accordance with the embodiments of the present invention can include an implant for positioning within a cervical facet joint for distracting the cervical spine, thereby increasing the area of the canals and openings through which the spinal cord and nerves must pass, and decreasing pressure on the spinal cord and/or nerve roots. The implant can be inserted laterally or posteriorly.
