Lumbar facet joint location and morphology. (Left) On the lumbar motion segment, two facet joints flank the spinous processes on the posterior aspect of the spine. (Middle) The facet capsular ligament (FCL) spans between two rigid articular facets from adjacent vertebrae creating the joint. (Right) The posterior aspect of the FCL consists of highly aligned collagen fibers bundles that preferentially align between the articular facets, whereas the anterior aspect (not pictured) is rich with elastin-like fibers.
