Abstract：Objective To investigate the clinical effect of modified sacral injection of triple drugs in the treatment of senilelumbar disc herniation.Methods Eighty patients with lower lumbarprotrusion of the discogenic pain were collected in the inpatients and outpatients in our hospital from November 2011 to June 2014 and divided in-to the treatment group(n=42) and the control group(n=42).The treatment group was given lidocaine 5 ml and dexamethasone 5 mg, vitamin B12 0.5 mg, 42~45 ℃20 ml of physiological saline for sacral canal injection, fol-lowed by sacral canal injection with lidocaine 5 ml, dexamethasone 5 mg, 42~45℃10 ml of physiological saline, 1 time every three days, three times as a period of treatment.The control group was given massage therapy, 1 time per day,10 times as a period of treatment.Results There were significant differences in VAS scores between the two groups at different time points(Ftime-point =9.76,Ptime-point=0.00), and the lowest scores occurred on the tenth day af-ter the treatment in both of the two groups.The VAS score of the treatment group was significantly lower than that of the control group(Fbetween-group =5.63, Pbetween-group =0.01).There were interactions between the different groups and the different time points(Fgroup category ×point =5.44, Pgroup category ×point =0.01).26 cases were cured, 14 cases improved and 2 cases invalid in the treatment group, and 15 cases were cured, 20 cases improved and 7 cases invalid in the control group.The clinical curative effect of the treatment group is better than that of the control group(Z=-2.574, P=0.010) .Conclusion Sacral canal injection of triple-drug therapy for elderly patients with lumbar disc herniation is safe and effective.It is suitabale for outpatient treatment.
