Study Design: Imaging supine sagittal alignment study.
Objective: Our goal was to determine differences between plain radiographs and computed tomography (CT) scans in supine sagittal alignment and to establish supine reference Cobb angles for both.
Summary Of Background Data: Few studies have compared plain radiographs versus CT scans with regard to sagittal spine alignment.
Study Design: This study was based on a post hoc analysis of data collected from a prospective FDA-regulated trial comparing total disc replacement to fusion surgery.
Objective: he purpose of this study was to determine if the occurrence of adverse events (AEs) had an impact on outcomes of low back surgery.
Summary Of Background Data: AEs are rigorously recorded during clinical trials primarily to evaluate the safety of the investigational device.
