As one of the restrictive lung diseases, scoliosis can be treated by surgical intervention to enhance the pulmonary function of that group of patients. The purpose of the study was to determine the effects of scoliosis correction on pulmonary function after a 6-month duration. Around 30 patients with scoliosis were aged between 10 and 40 years old subjecting to posterior spinal fusion surgery who had been enrolled in the study; all of them were subjected to Cobb’s angle measuring and pulmonary function test before and 6 months after the operation. Cobb’s angle before the operation was 57.3 ± 13.6°, which significantly corrected and reached up to 21.2 ± 7.2° postoperatively with a mean difference of about 36.13°, P < 0.001. The correlation of Cobb’s angle, forced vital capacity (FVC%), and vital capacity (VC%) was significantly negative. Pulmonary function showed restrictive pattern; forced vital capacity “FVC”, forced expiratory volume 1 “FEV1”, vital capacity “VC”, and forced expiratory flow “FEF 25–75%” were 62.4± 18.06, 65.6±20, 60.7±17.8, and 79.6±28.5, respectively; after 6 months, the reading changed to 60.9± 17.9, 64.04±19.3, 59.16±17.5, and 80.26±28.02 respectively with an insignificant difference, P>0.05. The pulmonary function showed insignificant changes after 6 months of operation, despite significant changes in Cobb’s angle while the preoperative FVC and VC were inversely correlated with it.

脊柱侧弯手术矫正前后的肺功能

作为限制性肺疾病之一，脊柱侧弯可以通过手术干预来治疗，以增强该组患者的肺功能。该研究的目的是确定6个月的持续时间后，脊柱侧弯矫正对肺功能的影响。参加这项研究的大约30名脊柱侧弯患者年龄在10至40岁之间，接受脊柱后路融合手术。所有患者均在手术前和术后6个月接受了Cobb角测量和肺功能测试。手术前的科布角为57.3±13.6°，经矫正后达到21.2±7.2°，平均差约为36.13°，P <0.001。柯布角，强迫肺活量（FVC％）和肺活量（VC％）的相关性显着为负。肺功能呈限制性模式。强制肺活量“ FVC”，强制呼气量1“ FEV1”，肺活量“ VC”和强制呼气流量“ FEF 25–75％”分别为62.4±18.06、65.6±20、60.7±17.8和79.6±28.5，分别; 6个月后，读数分别变为60.9±17.9、64.04±19.3、59.16±17.5和80.26±28.02，差异无统计学意义，P> 0.05。尽管Cobb角发生了显着变化，但术后6个月肺功能仍无明显变化，而术前FVC和VC与之呈负相关。分别为9±17.9、64.04±19.3、59.16±17.5和80.26±28.02，差异无统计学意义，P> 0.05。尽管Cobb角发生了显着变化，但术后6个月肺功能仍无明显变化，而术前FVC和VC与之呈负相关。分别为9±17.9、64.04±19.3、59.16±17.5和80.26±28.02，差异无统计学意义，P> 0.05。尽管Cobb角发生了显着变化，但术后6个月肺功能仍无明显变化，而术前FVC和VC与之呈负相关。
