Clinical study of transforaminal epidural combined bilateral L2 nerve root block in the treatment of discogenic low back pain
Objective:To evaluate the clinical efficacy of transforaminal epidural combined bilateral L2 nerve root block in the treatment of discogenic low back pain.Methods:A prospective randomized controlled method was conducted.From June 2022 to June 2023,patients with chronic discogenic low back pain who met the inclusion criteria were screened in the Pain Department of China-Japan Friendship Hospital.The patients in study group underwent transforaminal epidural block at affected intervertebral discs level and bilateral L2 nerve root block,while the patients in control group only experienced transforaminal epidural block.Numerical rating scale(NRS)pain score and Oswestry disability index(ODI)score were recorded at time before procedure and the 1st,the 3rd,and the 6th month after treatment.Results:A total of 92 DLBP patients who met the inclusion criteria were divided into study group(n=46)and control group(n=46).At the 1st and the 3rd month after treatment,the NRS scores of the study group and the control group were 1.7±0.6 vs.2.7±0.4 and 2.2±0.4 vs.3.2±0.5,respectively,with statistically significant differences between the two groups(P<0.05).At the 1st and the 3rd month after treatment,the ODI scores of the study group and the control group were 12.2±1.7 vs.17.4±2.1 and 16.1±2.1 vs.20.4±2.9,respectively,with statistically significant differences between the two groups(P<0.05).At the 6th month after treatment,there was no significant difference in NRS and ODI scores between the two groups(3.0±0.5 vs.3.2±0.6,21.4±2.0 vs.23.1±1.7).Compared with the base value,both groups showed significant reductions in NRS and ODI socres at the 1st,the 3rd,and the 6th months after treatment(P<0.001).Conclusion:Transforaminal epidural block can effectively alleviate discogenic low back pain and improve movement disorders.Transforaminal epidural combined with L2 nerve root pathway block is more effective than epidural block alone.
