Objectives: To Evaluate the effectiveness of epidural block injections guided by fluoroscopy made in Hospital San Jose for treating radicular lumbar pain, using a pain numeric scale and a disability questionarie
Methods: A prospective analitic study. Patients of 18 years or more with radicular lumbar pain of 3 or more months of evolution, with indication of epidural block guided by fluoroscopy, with no indication of surgery, were included. A numeric verbal scale and a functional Roland Morris Disability Questionarie were asked before the procedure and 1 week after. Improvement was determined as a redution of 50% of more and 40% or more respectively. The qualitative varibles were described in absolut and relative frequencies. The quantitative variables were described in medians and interquartilic ranges. The comparisons before and after the procedure between different gropus were made with Wilcoxon test, Chi2 and Kruskal Wallis test.
Results: 100 patients were enrolled, the improvement in pain scale were of 57% and 27% in functionallity. We did not find any statistically difference in these results when type of approach, laterlity and level of injection were compared.
Discussion: The epidural steroid injections made in patients with persistent symptoms have a good response in pain and functional scales.
