Abstract:
Objective To evaluate the clinical outcomes of lumbar spinal stenosis treated with three different surgical modalities.Methods One hundred and forty patients were treated with posterior lumbar interbody fusion (PLIF,n =50),transforaminal lumbar interbody fusion (TLIF,n =40) or modified method (n =50).The operation time and intraoperative blood loss were compared.The outcones were evaluated with Japanese Orthopedic Association (JOA) score and visual analogue scale (VAS),and the radiographic findings were also reviewed.Results The operation time was shorter and the intraoperative blood loss was less in modified group than those in other two groups (F =10.02,P ＜0.05).The excellent and good rate was 90％ (45/50) in PLIF group,92％ (37/40) in TLIF group and 90％ (45/50) in modified group.No complication happened in both TLIF group and modified group.Two patients had cerebrospinal fluid leakage in PLIF group.The JOA scores and VAS scores were significantly improved 3 and 6 months after surgery in three groups (F =10.66,9.68,11.03,all P ＜ 0.05).There were no significant differences in JOA scores and VAS scores among three groups before operation (P ＞ 0.05),also in JOA scores after operation among three groups.The VAS scores in TLIF group and modified group 3 and 6 months after operation were significantly lower than those in PLIF group (F =9.46,10.02,all P ＜ 0.05),but there was no significant difference between TLIF group and modified group.Interbody fusion was good in all three groups.Conclusions Three surgical methods have good clinical outcomes for lumbar spinal stenosis.But compared with PLIF and TLIF,the modified method has less blood loss,shorter operation time and less pain after operation.
