Postoperative Spondylolisthesis After Decompression for Lumbar Spinal Canal Stenosis -Report of Three Cases-

Abstract

Three out of 63 patients who had a partial facetectomy developed postoperative spondylolisthesis and required secondary fusion. We studied the changes in the lumbar spine radiologically to investigate the cause of postoperative spondylolisthesis.
Two of the three cases were shown to have had their facet joint damaged during the surgical procedure and the remaining case had congenital degenerative spondylolisthesis. We stressed the importance of preventing such damage in these spondylolisthesis patients before receiving surgery.
