ABSTRACT
Objectives To evaluate the correlation between radiologic changes (Pfirrmann and Modic) and radicular pain intensity in patients who underwent transforaminal endoscopic surgery for lumbar disc herniation. Methods Series of cases with 39 patients, 50 intervertebral discs in preoperative evaluation from January 29, 2018 to August 28, 2019 in an endoscopic spine surgery service. Demographic data, surgical indication, operative details and complications were obtained from medical records. The patients were divided into three groups based on the Modic classification (Modic absence, Modic 1 and Modic 2) and into two groups considering the Pfirrmann classification (Pfirrmann IV and Pfirrmann V). Data were processed in IBM SPSS Statistics for Windows, Version 22.0 (IBM Corp., Armonk, NY, USA), with a significance level of p < 0,05. Results There was no difference between genders; age 50,36 ± 15,05 years old; disease level L2-L3 1 (2%), L3-L4 2 (4%), L4-L5 9 (18%), L5-S1 8 (16%), L3-L4 + L4-L5 4 (8%), and L4-L5 + L5-S1 26 (52%); location right foraminal 7 (14%), left foraminal 15 (30%), central 9 (18%) and diffuse 19 (38%); radicular pain left 25 (50%), right 11 (22%), and bilateral 14 (28%); preoperative visual analogue scale (VAS) 9,5 ± 0,91, postoperative 2,5 ± 1,79; surgery duration 100 ± 31,36 minutes; and follow-up 8,4 ± 6,7 months. Less postoperative sciatica was registered in the Modic 2 versus Modic 1 group ( p < 0,05). There was no difference in the postoperative radicular pain between the Pfirrmann groups (IV versus V). Conclusion Although there is no clinical difference between the groups, in advanced stages of disc degeneration, endoscopic transforaminal discectomy proved to be effective in diminishing radicular pain in patients with lumbar disc herniation.
