Multicenter Study
Is There Additional Value to Flexion-Extension Radiographs for Degenerative Spondylolisthesis?
Multicenter retrospective study. ⋯ Flexion-extension radiographs may play a limited role in management of degenerative spondylolisthesis. The subset of patients for which flexion-extension views were most likely to provide value were patients with smaller slips (<7 mm) with no evidence of motion on standing radiographs versus MRI. In 90% of spondylolisthesis cases, information used for surgical planning may be ascertained by comparing motion between supine MRI and upright lateral radiographs.Level of Evidence: 3.

Multicenter Study Observational Study
Impact of New Motor Deficit on HRQOL after Adult Spinal Deformity Surgery: Subanalysis from Scoli Risk 1 Prospective Study.
International, multicenter, prospective, longitudinal observational cohort. ⋯ In the subgroup of deformity patients who developed a new motor deficit, total HRQOLs and HRQOL changes were negatively impacted. Patients with more than 2 points of LEMS worsening had the worst changes, but still showed overall HRQOL improvement at 6 months and 2 years compared with pre-op baseline.Level of Evidence: 3.
