Abstract ] Objective Tocomparetheeffectsofsimpledecompression , transforaminal
lumbarinterbodyfusion ( TLIF ), posteriorlumbarinterbodyfusion ( PLIF ) onlumbarstenosis
withⅠdegreedegenerativespondylolisthesis.Methods Onehundredandthreecaseswithsevere
unilateral symptoms , suffering from lumbar stenosis with Ⅰ degree degenerative
spondylolisthesis weredivededintothreegroups : simpledecompression group ( 38cases ),
transforaminallumbarinterbodyfusion ( TLIF , 31cases ) andposteriorlumbarinterbodyfusion
(
PLIF , 34cases ) .Intraoperativeindex , thedegreeofspondylolisthesis , lumbocruralpainvisual
