Abstract:
Objective To explore the clinical effect about the treatment of intrasacrospinal muscular approach and midline approach in lumbar interbody fixation with fusion for lumbar spinal stenosis.Methods Forty-two cases lumbar spinal stenosis were reviewed retrospectively in Meitan General Hospital from February 2009 to February 2014.All cases were divided into intrasacrospinal muscular approach and midline approach group(Group A,n =19) and midline approach group(Group B,n =23) according to the different surgical approach.Operation time,the amount of blood loss,post-operative drainage were compared.The VAS score of low back pain and leg pain preoperative and 6 months after operation were recorded.All cases were followed up for more than one year to evaluate fusion status.Results All cases were followed up for 13.0-20.0 months,with an average of (16.0± 1.2) months,all patients had bony fusion.Operation time,the amount of blood loss,postoperative drainage of Group A were significantly less than of Group B,the differences were significant ((95.1±4.5) min vs.(110.4±6.6) min,(75.2±5.1) ml vs.(159.8±7.2) ml,(53.6±4.3) ml vs.(86.2±14.1) ml;t =1.565,6.087,2.371;P＜0.05).VAS of back pain and leg pain at 6 months after operation of Group A showed better results than of Group B,the differences were significant((1.43±0.76) points vs.(1.39±1.00) points,(2.78± 1.23) points vs.(2.52±0.88) points;t =1.982,1.774;P＜0.05).Interbody fusion was obtained in two groups at the end of the last follow-up.Conclusion The intrasacrospinal muscular approach and midline approach for lumbar interbody fixation with fusion for lumbar spinal stenosis is better in less injury to paraspinal muscle,less blood loss and less post-operative drainage,which contributes a rapid recovery.
