Conditions

Degenerative Spondylolisthesis, Transforaminal Lumbar Interbody Fusion

Brief summary

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

Detailed description

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

Interventions

PROCEDUREUnilateral Transforaminal Interbody fusion

TLIF via unilateral factectomy and insertion of one cage

PROCEDUREBilateral Transforaminal Interbody fusion

TLIF via bilateral factectomy and insertion of two cages
