Method for accessing a spinal facet joint

摘要

A minimally invasive method for accessing a facet joint of the spine is provided. Embodiments of the method include creating a small incision directly over the facet joint and to allow direct access and visualization of the joint. A second incision, which may be a puncture wound, is provided at a distance from the first incision. A path between the second incision and the facet joint is then formed which may be curved or substantially straight. The path is preferably configured to intersect both facet surfaces. The path may be formed using an instrument which can be used to drill a hole across the facets, insert a fastener across the facets, or the like.

主权项

1. A method for providing access to a spinal facet joint, the method comprising:
providing a first incision directly over the facet joint, the first incision allowing direct visualization of a superior or an inferior articular process and the facet joint which includes a facet on the superior or the inferior articular process; retracting sides of the first incision to reveal the facet joint; creating a second incision at a particular distance from the first incision, wherein the second incision is ipsilateral to the facet joint; creating a path between the second incision and the facet joint, such that the path intersects an articular surface of each facet of the facet joint, the second incision provided at a distance from the first incision that is not so large that the path from the second incision to the facet joint intersects or penetrates the peritoneum; and positioning a fastening member across the facet joint.
