is there a relationship between major thoracic curve correction and pulmonary function test improvement?
STUDY DESIGN: Prospective clinical study. OBJECTIVE: To investigate if a correlation exists between various parameters including major thoracic curve correction and postoperative pulmonary function test (PFT) improvement at 2 years postoperative following posterior segmental spinal fusion (PSSF) and instrumentation with iliac crest bone graft (ICBG). SUMMARY OF BACKGROUND DATA: There are no studies available on the correlation between major thoracic curve correction and postoperative PFT improvement following PSSF and instrumentation with ICBG with a homogenous diagnosis, similar operation method, and similar age population. METHODS: One hundred thirty-nine patients with adolescent idiopathic scoliosis (Lenke type 1-4), undergoing PSSF and instrumentation with ICBG at a single institution, were before surgery and 2 years after surgery prospectively evaluated in regard to PFTs, assessing forced vital capacity, and forced expiratory volume in 1 second. PFTs change at 2 years postoperativ
