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.<jats:italic>Methods<\/jats:italic>. We retrospectively evaluated 240 patients (124 males and 116 females) with a mean age of<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\"><mml:mn>36.4<\/mml:mn><mml:mo>\u00b1<\/mml:mo><mml:mn>5.9<\/mml:mn><\/mml:math>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.
