Correlation of preoperative deformity magnitude and pulmonary function tests in adolescent idiopathic scoliosis

STUDY DESIGN: Clinical study correlating preoperative pulmonary function tests (PFTs) to radiographic measures of thoracic deformity severity in adolescent idiopathic scoliosis (AIS) patients. OBJECTIVE: To determine (1) the incidence of clinically relevant (<65% predicted value) pulmonary impairment in AIS patients; (2) if patients with more severe deformity have greater impairment of PFTs than those with lesser deformity; (3) the effect, if any, of juvenile onset deformity (onset65%. Patients with MT curves>70 degrees , and especially >80 degrees ; proximal thoracic (PT) curves which were >30 degrees or structural; or T5-T12 kyphosis<10 degrees had significantly (PKeywords : Adolescent,Child,Female,Forced Expiratory Volume,Humans,Incidence,Lung,Male,methods,Morbidity,pathology,Patients,physiopathology,Preoperative Period,Regression Analysis,Respiratory Function Tests,Rotation,Scoliosis,Spinal Fusion,surgery,Texas,Thoracic Vertebrae,Treatment Outcome,Vital Capacity,Young Adult,, Preoperative,Deformity,Magnitude, small fibre neuropathy uk
