Abstract:
Objective To analyze the influence factors of long-term efficacy of different fusion combined with pedicle fixation for lumbar spondylolysis.Methods The surgical and postoperative follow-up data of 196 cases with lumbar spondylolysis were analyzed retrospectively.Age,gender,body mass index ( BMI ),disease course,preoperative Japanese orthopaedic association (JOA) score,fusion segments,fusion method,immediate postoperative recovery rate and postoperative functional exercise,which might affectlong-term operation efficacy,were selected to undergo single-factor analysis and multivariate regression analysis.Results All the patients were followed up for 5-9 years and 5.4 years for average,163 cases got excellent or good curative effect,the rate of excellent and good effect was 83.2％( 163/196);33 cases got poor efficacy.There was no cerebrospinal membrane tear,cerebrospinal fluid leakage,infection,fracture fixation and other complications happened after operation.Single-factor analysis showed that disease course,BMI,preoperative JOA score and postoperative functional exercise had obvious relation with long-term efficacy (P ＜ 0.05 ) ;while age,fusion method,fusion segments,immediate postoperative recovery rate and gender had no significant relation with long-term efficacy (P ＞ 0.05).Multivariate regression analysis showed that disease course,preoperative JOA score,postoperative functional exercise were important factors influencing long-term efficacy (OR =1.423,2.089,1.320,P=0.023,0.012,0.034).Conclusions Disease course,preoperative JOA score,postoperative functional exercise are important factors influencing long-term efficacy of surgery for patients with lumbar spondylolysis.
