Ligaments of the spine

I spent some time reading up on deep ligaments of the spine today:
Anterior longitudinal ligament
Posterior longitudinal ligament
Ligamentum flavum
Interspinous ligament
Supraspinous ligament

I non specific low back pain it's really virtually impossible to pin down one structure as the source of pain. But in the light of a detailed clinical examination it's useful to have some suspects.
