The superior facets in the lumbar region face which directions?

In the lumbar spine, the superior articular facets are oriented posteromedially—toward the back and toward the midline. This backward and inward direction supports the lumbar pattern of movement, allowing flexion and extension while limiting rotation. If they faced forward or laterally, the facet joints would guide movement differently, promoting more rotation or misalignment for typical lumbar motion. So the back-and-inward (posterior and medial) orientation best matches how the lumbar facets actually function.
