摘要:
Systems and method in accordance with an embodiment of the present invention can includes an implant comprising a spacer and a frame having a central body and a helical shaped wing extending from the central body. The frame can be positioned near about adjacent spinous processes, and can be rotated and urged so that the adjacent spinous processes pass within a groove of the wing, thereby allowing the wing to be arranged on an opposite side of the adjacent spinous processes. The spacer can then be arranged over the frame so that the spacer contacts and distracts the spinous processes, thereby limiting relative movement of the adjacent spinous processes during extension.

An embodiment of a system in accordance with the present invention can include an implant having a spacer with a thickness and a wing, wherein a first configuration of the wing has a first height substantially similar to the thickness and wherein the wing is adapted to be selectably arranged in a second configuration such that the wing has a second height greater than the first height. A periphery of the implant has a shape generally conformal with a shape of an inner surface of a cannula and a cross-sectional diameter smaller than an inner diameter of the cannula. The cannula is inserted such that a proximal end of the cannula is arranged between the adjacent spinous processes. The implant is then urged into position between the adjacent spinous processes by way of the cannula, and subsequently arranged in a second configuration to fix the implant in position.

Systems and method in accordance with an embodiment of the present invention can includes an implant comprising a first wing, a spacer extending from the first wing, and a distraction guide. The distraction guide is arranged in a first configuration to pierce and/or distract tissue associated with adjacent spinous processes extending from vertebrae of a targeted motion segment. The implant can be positioned between the adjacent spinous processes and once positioned, the implant can be arranged in a second configuration. When arranged in a second configuration, the distraction guide can act as a second wing. The first wing and the second wing can limit or block movement of the implant along a longitudinal axis of the implant.

An implant for positioning between the spinous processes of cervical vertebrae include first and second wings for lateral positioning and a spacer located between the adjacent spinous processes. The implant can be positioned using minimally invasive procedures without modifying the bone or severing ligaments. The implant is shaped in accordance with the anatomy of the spine.

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.

This invention relates to tools for preparing vertebral bodies in the spine for the implantation of an artificial vertebral disk replacement and related method. A first tool is disclosed that prepares the vertebral bodies for implantation by cutting offset channels in the vertebral bodies. The second tool holds two plates of the implant during the implantation process. This invention also relates to an artificial vertebral disk replacement, a method of operation, and a method of implanting.

摘要:
Systems and method in accordance with the embodiments of the present invention can include an implant for positioning at a vertebra for resisting the expulsion of a bone graft from within an intervertebral space. The implant includes a buttress plate having an intervertebral plate and an anchoring plate connected such that the intervertebral plate can move relative to the anchoring plate.
