Abstract
A facet joint surgical tool for treating a facet joint synovial cyst includes rotatable members disposed side-by-side through a minimally invasive sheath and rotatable to reconfigure distal end portions between a facet joint penetration configuration with a tissue piercing tip and a facet joint retraction configuration. Facet joint synovial cysts located to an anterior side of the facet joint are treated by a posterior approach with access to the cyst through the facet joint retracted by the surgical tool. Facet joint synovial cysts located to a posterior side of the facet joint are treated by direct access from a posterior approach.
