Split–spinous process laminotomy and discectomy for degenerative lumbar spinal stenosis: a preliminary report

Abstract

A Marmot operation may provide effective spinal decompression. Although this method requires more operative time than a conventional method, it may involve only minimal muscular trauma, spinal stability maintenance, and early mobilization; shorten the duration of hospital stay; reduce postoperative back pain; and provide satisfactory neurological and functional outcomes.
