Abstract
A method for augmenting a facet joint. The method includes exposing the posterior aspects of a spinal motion segment in a first incision, preparing an access path through a separate postero-lateral percutaneous incision using a drilling instrument that traverses through at least a portion of the lamina and an inferior facet articulation surface, and terminates within the facet joint gap, and injecting augmentation filler into the facet joint gap.
