Title: Evaluation of Radiological Changes after Percutaneous Discectomy.
Abstract: We investigated MRI and X-ray changes in operated discs in patients following percutaneous discectomy.Sixty-six patients were examined by MRI pre and post operatively, and the degree of the herniated disc was measured in sagittal imaging. Reduction of the herniated disc was seen in 49 disc levels (67.1%)The X-rays of forty patients available for follow-up showed disc space narrowing in twenty (42.6%) and four with unstable an intervertebral space (8.5%).However these changes were not well correlated with the clinical results.
