腰椎椎間板ヘルニアに対する microdiscectomy の経験

抄録

Eighteen patients of herniated lumbar disc were treated with microlumbar discectomy in 1989, and were compared with 20 patients treated with Love's nucleotomy. Using this method, intraoperative bleeding decreased to 69 grams, and the postoperative period for ambulation has averaged 2.2 days and postoperative stay 9.4 days, which were far shorter than the period with Love's nucleotomy. The mean operatig time was 83 minutes, and the improvement rate by JOA score was 81.3%, which were almost the same as those with Love's nucleotomy. Microlumbar discectomy seems to have good application for the first operating intracanal hernia with clear laterality from the disc wihtout so much degeneration or instability.
