Lumbar Facet Joint Arthritis Is Associated with More Coronal Orientation of the Facet Joints at the Upper Lumbar Spine

<table>FJ arthritis and FJ orientation. On the left side, sagittally oriented FJs at L2/3 and coronally oriented FJ at L5/S1 are associated with normal FJs at the lumbar spine. The right side illustrates inversely oriented FJs with arthritic FJs at the lumbar spine, namely, coronals oriented FJs at L2/3 and sagittally oriented FJs at L5/S1.</table>
