Analysis Of The Early Term Efficacy Of The Treatment Of Lumbar Disc Herniation Uniting The Disc-FX System With Transforaminal Epidural Steroids Injection

Objective:Observing early term efficacy of Disc-FX system technique combined with transforaminal epidural steroids injection(TFESI) and the simple Disc-FX system for lumbar disc herniation, comparing the amount of pain reduction and maintain time of the two surgical procedures. Providing clinical evidence of minimally invasive surgery for lumbar disc herniation.Methods:From February2012to August2013,32patients with single-level contained lumbar disc herniation(HIZ) with radicular pain are included in the research.16patients including10men and6women use Disc-FX system combined with transforaminal epidural steroids injection for the treatment group, another16patients including9men and7women use the simple Disc-FX system for the control group. There was no significant difference between two group in the sex, the age, the weight, the disease course, the VAS scores of the back and low limb pain.Comparing the visual analogue scale(VAS) score of the two group to evaluate the back and low limb pain at preoperative, postoperative1week,3months,6months by independent-Sample T test. We consider that the research are statistical if P<0.05.The JOA score was also evaluated at postoperative6months.Results:The surgery of two groups are completed smoothly, not surgical complications appeared during the follow-up. The VAS score of the treatment group preoperation low back pain is5.19±1.68, The VAS score of low back pain at postoperation1week,3month,6month are1.50±0.82,1.31±0.87,1.13±0.81, respectively. The postoperative low back pain VAS score of the treatment group decreased significantly compared with that preoperative. The preoperative limb pain VAS score of the treatment group is6.50±1.21, The VAS score of limb pain at postoperative1week,3months,6months are2.06±0.68,1.63±0.81,1.06±0.77, respectively. The postoperative limb pain VAS score of of the treatment group decreased significantly compared with that preoperative. The low back pain VAS score of the control group preoperation is5.06±1.48, The VAS score of low back pain at postoperation1week,3month,6month are3.75±1.00,2.75±0.78,3.06±0.77, respectively. The postoperative low back pain VAS score of the control group decreased significantly compared with that preoperative. The preoperative limb pain VAS score of the control group of is6.81±1.11, The VAS score of limb pain at postoperative lweek,3months,6months are4.50±1.56,3.00±0.63,3.25±0.86, respectively. The postoperative limb pain VAS score of the control group decreased significantly compared with that preoperative. According to the MacNab’s evaluation criterion, in the treatment group, the evaluation of JOA score is excellent in8patients, good in6, fair in1, and poor in1, suggesting an effective rate of87.5%(14/16), in the control group, the evaluation of JOA score is excellent in6patients, good in5, fair in3, and poor in2, suggesting an effective rate of68.8%(11/16).Conclusion:Compared with the simple Disc-FX system, Disc-FX system combined with transforaminal epidural steroids injection can give satisfactory clinical outcomes during a short-term follow-up and last longer. The effective rate are higher.
