Abstract

Background. In lumbar disc herniation, most authors recommend nonoperative treatment for the first few weeks of presentation, but what about the upper limit of this golden period? The aim of this study is to assess the effect of preoperative sciatica duration on surgical outcome of lumbar disc herniation. Methods. We retrospectively evaluated 240 patients (124 males and 116 females) with a mean age of years (range 16 to 63) surgically treated due to primary stable L4-L5 disc herniation. The patients were placed into two groups: with more and less than 12-month duration of preoperative sciatalgia. Disability and pain were measured by Oswestry Disability Index (ODI) and Visual Analogue Scale (VAS). Wilcoxon test and Mann-Whitney test were used for statistical analysis. Results. Total mean duration of preoperative sciatalgia and follow-up period were 13.3 months (range 2 to 65) and months (range 24 to 72), respectively. Comparison between the groups showed that duration of preoperative sciatalgia either less or more than 12 months did not affect the surgical outcomes significantly. Conclusions. More or less than 12-month duration of preoperative sciatalgia may not affect the surgical outcomes of simple lumbar disc herniation in the patients undergoing discectomy.
