Therapy effect of transforaminal lumbar interbody fusion technical on complex lumbar spinal stenosis / 中国综合临床

ABSTRACT

Objective To investigate the surgical effect on complex spinal canal stenosis of lumbar spine through the technical of transforaminal lumbar interbody fusion (TLIF).Methods The retrospective analysis was performed on 46 patients admitted from December 2008 to March 2012.Of all patients,spinal canal stenosis of lumbar spine associated with lumbar scoliosis were 13 cases,lumbar sondylolisthesis for 17 cases,lumbar discogenic pain for 11 cases,lumbar revision surgery for 5 cases.All were underwent the surgical procedures including correction,internal fixation with pedicle screw,then use TLIF technology to compression and fusion.JOA,VAS,Nahal evaluating standards were applied to evaluate the therapeutic effect.The intervertebral height and bone fusion were observed by X ray.Results Forty-six patients were get follow-up for 6-36 months with an average of 12 months.There was significant difference (P ＜0.05) in JOA score between preparation (11.5 ± 2.2) and postoperation (22.5 ± 3.5).VAS score was (2.68 ± 2.08) at pre-operation,lower than that in postoperation (7.25 ± 1.85).There showed the excellent bone fusion,non loss of correction angle and the height of intervertebral disc space.Conclusion The complex of lumbar stenosis is difficult to operate and with high risk.Application of the TLIF procedure combined with clinical symptom,imaging of the spinal cord to decompression,fusion and fixation can restore the spine physical curve and improve patient's symptom.
