ABSTRACT
Objective To retrospectively analyze pulmonary function changes after growing rod surgery for progressive early-onset scoliosis.Methods Ten cases of progressive early-onset scoliosis treated with growing rod technique from September 2002 to July 2011 were enrolled in the study.There were 3males and 7 females,aged from 6 to 9 years (average,7.0±1.1 years).Four patients had finished the final fusion surgery (Group fusion),and 6 patients (Group non-fusion) were in the process of periodic lengthening.Forced vital capacity (FVC),FVC/predicted FVC ratio,forced expiratory volume in one second (FEV1),FEV1/predicted FEV1 ratio,Cobb’s angle,and C7-S1 distance before each surgery were recorded.Lung function changes and correlations between lung function changes and radiographic changes (Cobb’s angle and C7-S1 distance) were analyzed.Results In Group fusion,both FVC and FEV1 increased,and FVC showed a significant difference.In Group non-fusion,FVC and FEV1 also increased and both showed a significant difference.FVC/predicted FVC ratio and FEV1/predicted FEV1 ratio both changed similarly and did not show statistical differences in the two groups.There were no significant correlations between lung function changes and radiographic changes (Cobb’s angle and C7-S1 distance).Conclusion Pulmonary function improves after growing rod surgery for progressive early-onset scoliosis.The pulmonary function changes do not correlate with changes of Cobb’s angle and C7-S1 distance.
