Comparative Study on MRI before and after Percutaneous Nucleotomy.

Abstract

We investigated the clinical utilities of MRI in patients who underwent percutaneous nucleotomy. Fifty-four patients were examined by MRI pre-and postoperaively, and the degree of the herniated disc was measured in saggital imaging. Reduction of the herniatd disc was seen in 28 cases (54%). In 8 cases, Over 2mm reduction was acquired and all of them had excellent results. We considered that one of the major factors for relieving pain is the direct decompression for the nerve roots and the dural sac.
