We reviewed the surgical results of 18 patients suffering from thoracic myelopathy caused by ossification of the yellow ligament (OYL) and investigated the factors affecting postoperative results. The percentage of clinical recovery, which was calculated from the JOA score before and after surgery, averaged 54.9%. Factors investigated were age at surgery, delay of surgery after onset of symptoms, JOA score before surgery and percentage of narrowing of spinal canal calculated from CT myelography. Correlation between percentage of clinical recovery and these factors were analyzed. There was a significant negative correlation between the percentage of clinical recovery and delay of surgery. No significant correlation was found between the other factors. Therefore, we recommend early diagnosis and early surgery without delay.
