Abstract
A system for treating a facet joint of a patient including superior and inferior resurfacing devices. The superior device includes a resurfacing body configured to conform to a shape of a superior facet articular face, and the inferior device includes a resurfacing body configured to conform to a shape of an inferior facet articular face. Each resurfacing body exhibits sufficient flexibility to transition from a relatively flat state to an inserted state in which the resurfacing body substantially matches any multi-planar concavities of the corresponding facet articular face in the presence of compressive forces. With this construction, the system is capable of establishing a new sliding interface within the facet joint, and can be inserted on a minimally-invasive basis. The resurfacing bodies can be formed of PEEK, and can include teeth that engage the corresponding facet articular face.
