Short term effects of scoliosis surgery on lung function
Wilcoxon signed rank test was used to compare LFT results prior to and after surgery in 43 patients. No significant change was observed of absolute values of (F)VC, FEV1/FVC and PEF prior to surgery compared to 3-4 months after surgery (table 2). Standardized values of (F)VC and PEF were significantly lower 3-4 months after surgery compared to results before surgery. Subgroup analysis in patients with NMDs showed similar results.
