title: Analysis of preoperative prognostic factors in first-time surgery for lumbar disc herniation, including Finneson's and modified Spengler's score systems.
abstract: In a retrospective study, 18 preoperative demographic and physical variables were evaluated for their preoperative prognostic value in 261 patients, following first-time lumbar disc surgery. Special reference was given to the Spengler and Finneson index-scores. "Low Back Pain Rating Scale" was used as the outcome assessment instrument. Comprehensive statistical analysis was undertaken in order to separate only the contingently independent variables. Gender was a highly significant prognostic factor. Other independently statistically significant prognostic factors include dermatomal hypoalgesia, smoking, and the Finneson index score. Results of the study are discussed with reference to the available literature.
