Lumbar Spine Pathology Zygoapophysial Facet Joint Syndrome chiropractry 3D animations. Shows a lateral view of a normal L4-5 facet joint and its medial branch nerve innervation, during lateral flexion. Also shows the path of the two medial branch nerves innervating the facet joint capsule. Then the capsule is irritated, and the chiropractry 3D animations.
FACET JOINTS
The facet joints in the spine have articular cartilage. They are surrounded by a capsule with an inner synovial membrane that secretes synovial fluid to lubricate and nourish the joint. The capsule has nerve endings that are used for movement awareness, pain sensation and controlling protective muscle reflexes.
FACET JOINT SYNDROME
Facet joint syndrome refers to a range of symptoms caused by acute inflammation (trauma, infection) or chronic degeneration (osteoarthritis) of a facet joint.
