title: [Clinical significance of the spontaneous regression or absorption of protruded nucleus pulposus in the patients with lumbar disc protrusion].
abstract: There were many studies about the regression of protruded nucleus pulposus (PNP) in lumbar dlisc protrusion (LDP) patient evidenced by CT scanning after conservative therapy at the end of last century. The studies were supposed to prove the effectiveness of the therapy but aroused dispute ever since for that the slice of CT rescanning cannot meet precisely with the previous scanning before the therapy. After the popularity of MRI, the evidence of spontaneous regression of PNP was finally confirmed according to recent clinical and pathological studies about PNP regression detected by MRI. The ambiguity might change the view of traditional principle of conservative therapy on LDP.
