Correlations of Adolescent Idiopathic Scoliosis and Pectus Excavatum

STUDY DESIGN:Radiologic study of scoliosis in pectus excavatum patients. OBJECTIVES:To determine the relation between pectus excavatum deformity and adolescent idiopathic scoliosis (AIS). SUMMARY OF BACKGROUND DATA:AIS may be related to other whole body deformities, but few reports have addressed the relation between chest deformity and scoliosis. METHODS:A total of 248 patients with a diagnosis of pectus excavatum were enrolled in this study. All study patients underwent whole spine anteroposterior radiographs and chest computed tomography. Severity and type of scoliosis and chest deformity were measured using radiographs, and relations between pectus deformity and AIS were analyzed. RESULTS:Overall, 56 of the 248 study patients had scoliosis (Cobb angle >10 degrees)—a prevalence of 22.58%. The incidence of scoliosis was significantly higher in female patients (38.46%) (P=0.002), and Lenke type 1 predominated in pectus patients (48.2%, P
