The posterior ligaments here, supraspinous and intraspinous which are in between the spinous processes, major resistors of flexion; so if you have any sort of a flexion based injury or posterior element tenderness, you have to worry about disruption of this very important ligamentous complex. Anterior longitudinal ligament is a big, thick structure that attaches to the vertebral bodies and the disc, tends to resist extension but a very, very important auxiliary structure to resist torsion. The main way to resist torsion are in the facets, so any time those structures are compromised, you are going to have relative torsional incompetence. Most of these structures are very, very richly innervated and virtually any structure in the back can be a source of pain contrary to conventional wisdom. Probably the leading offender in that, is the intervertebral disc. If you look in Gray’s anatomy, and not that I would advise you to do that on a regular basis, what you will see, up until the additional before last, I think that’s the 670th edition as far I know, you will see the largest, avascular, neural structure in the body, the L4-5 disc. Well that’s wrong on two levels; number one, it’s L3-4 on population studies, that’s a little bit larger than L4-5. Number two, it’s avascular, but it’s not neural. The outer 50% of the disc is richly innervated with nociceptor fibers and free nerve endings, and in fact, the disc itself can be a source of pain, even in the absence of a disc herniation compressing a nerve root and causing sciatica, and that work has been done in Australia with some very, very elegant histological studies.

It you notice, there is the nerve root exiting the canal, there is a posterior branch, the facet capsules branch to the supraspinous and intraspinous ligaments, and there are all afferent pathways in here, so all these things are capable of conducting painful impulses centrally, and of course, the disc, you can see the nerve of the vertebral body, the sign of vertebral nerve and don’t forget the sympathetics which are out here as well, which carry some sensory information. What is one of the structures in the back that is probably most vulnerable to injury, and the problem is, it’s the intervertebral disc. If you look at the disc, it does a reasonably good job at resisting axial stress. Here is the jelly-like nucleus and the fibers annulus and circumferential lamella around that. The problem is, it does not do a very good job at resisting torsion, and in fact, if you take a functional spinal unit to the lab which would be the vertebra and adjacent soft tissues, you will see that the disc will fail in torsion long before it fails in any other deflection, flexion, extension, side gliding, lateral bending.
