Forty-six operated patients with lumbar canal stenosis were reviewed. Especially, the patients who underwent posterior approach surgery were examined in this study with postoperative changes on myelogram and MRI. The results were as follows: 1) Over-all clinical results were good in 56.5%, fair in 39.1%, and poor in 4.4% of the cases. 2) In the wide laminectomy, clinical results were good in 52.6%, fair in 42.1% and poor in 5.3%, and that of the fenestration wre good in 42.9%, fair, in 42.9%, and poor in 14.2%. 3) Clinical results did not appear to be entirely correlated with the postoperative changes on myelogram and MRI. In conclusion, we think that the wide fenestration is the first-choice method as a posterior approach surgery, but in the severe and widely compressive case, the wide laminectomy is better than the wide fenestration.
