Eighteen patients with non-surgically treated lumbar disc herniation u
nderwent follow-up CT examination at an average of 5.2 years (range 4.
3-6.1 years) after their initial examination. In 12 of the patients di
sc herniation had resolved, although only five of these patients had c
omplete relief of symptoms. Although disc herniation has a tendency to
heal spontaneously, there is poor correlation between the morphologic
al changes and the relief of pain.
