특발성 척추측만증 환자의 방사선학적 지표와 폐기능, 흡기 능력의 관계

Abstract

[PURPOSE] The purpose of this study was to investigate the relationship between radiological indices, pulmonary function, and inspiratory capacity in patients with idiopathic scoliosis after taking into account their age, height, weight, muscle mass, and BMI. [METHODS] We enrolled a total of 31 female patients with mild to moderate, right-sided idiopathic scoliosis. We took standardized standing anteroposterior and lateral radiographs using full spine radiography. The following radiological indices were measured: the thoracic Cobb's angle, the level of shoulder asymmetry, the pelvic tilt, the thoracic kyphotic angle, and the number of vertebra. Pulmonary function was measured as the maximum inspiration volume, and our measures of inspiratory capacity were inspiratory pressure and inspiratory velocity. Pearson's and partial correlation analyses were used to analyze data. [RESULTS] We found that pulmonary function was not significantly correlated with age, height, weight, muscle mass, or BMI in patients with mild to moderate idiopathic scoliosis or with a thoracic Cobb’s angle of less than 40°. But we found that inspiratory capacity was significantly correlated with these factors save for height (p<.05). After adjusting for these factors, we found that radiological indices were not significantly correlated with either pulmonary function or inspiratory capacity in these patients. [CONCLUSIONS] After adjusting for factors associated with inspiratory capacity, we found that radiological indices in patients with mild to moderate idiopathic scoliosis were not associated with respiratory parameters such as pulmonary function and inspiratory capacity. Therefore, our data suggest giving a consultation of a possible impairment in pulmonary-related function to such patients on the basis of radiological findings such as the Cobb’s angle may be ungrounded and should be refrained.
