Abstract
Various implementations for therapy to facet joints connecting vertebrae are disclosed including: A) Facet joint stabilization that may be implemented using stabilization band that maintains tension between two anchors. The stabilization band may be retained in any one of a number of ways including the use of an anti-slip device such as a mechanically deformed crimp that abuts one of the anchors. B) Facet joint augmentation may be implemented by dilating the facet joint and inserting a facet joint spacer before adding a facet joint stabilization assembly. The facet joint augmentation may include connecting a tail section of the facet joint spacer to the first anchor used in the facet joint stabilization assembly. C) Facet joint immobilization may be implemented by inserting a fastener across the facet joint and into the vertebra so that the assembled fastener expands inside the vertebra.
