Abstract
Thirty-six patients with lumbar canal stenosis were treated with restorative laminotomy(RL: 25 patients)or laminectomy (LE: 11 patients), and the postoperative clinical results were compared between two groups. The mean improvement rates were 70.0% in RL and 59.5% in LE. The mean hospital stay after surgery in RL was shortened statistically, and the mean low-back-pain score six months after surgery in RL was superior statistically. In RL, bony union of restored laminae was observed on CT scan 4 months after surgery on average. The short-term clinical results of restorative laminotomy for lumbar canal stenosis were encouraging.
