Unilateral Versus Bilateral TLIF for Degenerative Lumbar Spondylolisthesis

Comparison of Radiologic and Clinical Outcome of Single Level Lumbar Interbody Fusion Between Unilateral or Bilateral Facetectomy : Prospective Randomized Controlled Trial

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"

Inclusion Criteria:

• lumbar degenerative spondylolisthesis
• indicated for surgery

Exclusion Criteria:

• not agreed for the study
