The impact of urgent intervention on the neurologic recovery in patients with thoracolumbar fractures.

Background: We carried out an observational longitudinal retrospective study between 2000 and 2009 in 28 patients who underwent surgery for unstable vertebral fractures with neurologic deficits.

Methods: For the statistical analysis, we used the Chi-test to compare proportions in independent groups and the exact Fisher test and the Wilcoxon test for repeated measures, and we compared the mean values using the Mann-Whitney U test at a significance level of P<0.05.
