Pulmonary function study in Adolescent Idiopathic Scoliosis before and after surgical correction

Abstract

From July 2018 to August 2021, 20 patients with adolescent idiopathic scoliosis requiring surgical correction were admitted in AL KARAMA teaching Hospital. They were 18 female and 2 male with age range from 13-20 years (15.1 years mean). The curve magnitude by Cobb’s method ranged from 45-80 degrees (57 degree of mean). The vital capacity ranged from 1.1-3.5ml (2.33 ml of mean) and the height ranged from 138-158cm (148.9cm of mean). They had all undergo surgical correction, postoperatively the curve was corrected from mean of 57 degree to mean to mean of 28 degree (22-40 range), the vital capacity improved to mean of 2.89 ml, and 3.05 ml three months postoperatively and one year postoperatively respectively. The height was corrected to mean of 152.3 cm postoperatively. All these changes in the above mentioned parameters were significant, the P value < 0.05. Despite the variation in reports about the fate of pulmonary function test (PFT) after surgical correction, our humble study is in the favour of improvement not only in PFT, but also the height.
