Abstract:
Forty three patients with L5-S1 spondylolisthesis undergoing surgical treatment from April 2012 to November 2014 were included for analysis,including 20 cases received transforaminal lumbar interbody fusion (TLIF group) and 23 cased received posterior lumbar interbody fusion (PLIF group).The incision length,operative time were shorter and blood loss was less in TLIF group than those in PLIF group [(9.6±0.9) vs.(16.1±1.5) cm,(125.6±13.0) vs.(156.4±11.8) minand (218.7±22.5)ml vs.(326.5 ±20.1) ml,respectively,all P =0.000].There was no statistical difference in the S1 pedicle screw (S1PS) insertion point between two approaches[(29.4 ± 1.9) vs.(28.5 ± 1.0) mm,P =0.069],but the distance from the midline to the lateral edge of the screw (12.9 ±3.6) mm,S1PS angle (23.3 ±2.1) ° and length of S1PS length with the sacral body (40.9 ± 2.6) mm in the TLIF group were better than those in PLIF group (P =0.000).Our results demonstrate that the paraspinal muscle approach for the treatment of L5-S1 spondylolisthesis may be superior with less trauma,better functional recovery and stable screw placement.
