Maximal Voluntary Ventilation (MVV) Testing in Orthopaedic Clinic Demonstrates Pulmonary Improvement Following PSF for AIS

Background: In patients with severe adolescent idiopathic scoliosis (AIS), maximal voluntary ventilation (MVV) has been shown to be more strongly correlated with Cobb angle than forced vital capacity (FVC) in an orthopaedic office setting. We sought to evaluate pulmonary function of AIS patients with changes in Cobb angle over time. Methods: 49 AIS patients with …
