A prospective randomized controlled trial for comparison of radiologic outcomes of "single level transforaminal interbody fusion(TLIF) technique via unilateral versus bilateral facetectomy for the treatment of lumbar degenerative spondylolisthesis
Traditionally many spine surgeons prefer single level TLIF surgery via bilateral facetectomy for increasing union rate. Our hypothesis - "Single level TLIF via unilateral facetectomy is sufficient for achieve successful fusion rate"
