Multicenter Study Comparative Study
Results of selective thoracic versus nonselective fusion in Lenke type 3 curves.
A retrospective analysis of a prospectively collected multicenter database. ⋯ Despite preoperatively smaller lumbar curves with less apical translation and lumbar prominence, most patients with selective fusions were out of balance postoperatively and had inferior radiographical outcomes as compared with their nonselective comparison cohort with similar patient-reported outcomes. Long-term follow-up is required to determine whether the trade-off of sparing motion segments at the expense of somewhat lessened radiographical outcomes is worthwhile.

This article comprises a review of the literature pertaining to the normal and pathological lumbar disc and the compilation of a standardized nomenclature. ⋯ We have revised and updated a document that, since 2001, has provided a widely accepted nomenclature that helps maintain consistency and accuracy in the description of the properties of the normal and abnormal lumbar discs and that serves as a system for classification and reporting built upon that nomenclature.
