腰部脊柱管狭窄症における多椎間開窓術

抄録

A review was made of eighteen cases of degenerative lumbar spinal canal stenosis. Cases associated with spondylolisthesis were excluded. Seventeen males and one female had a mean age of sixty-five years.
Intermittent claudication in seventeen cases, sensory disturbance in seventeen cases, low back pain in fourteen cases, muscle weakness in ten cases, and B-B dysfunction in four cases were the preoperative clinical manifestations.
Myelography revealed total thirteen complete blocks in the intervertevral spaces of the eleven cases, incomplete blocks in the spaces of the fifteen cases.
All were treated surgically with the method so called “multiple fenestration”, including fenestration of the inter-laminae space, superior and inferior facetectomy and resection of the yellow ligament. Fusion was not made simultaneously. Marked improvement of the clinical symptoms was noted postoperatively in all of the cases.
Multiple fenestration without fusion was a useful technique in case of degenerative lumbar spinal canal stenosis.
