Abstract:
STUDY DESIGN: Retrospective study OBJECTIVES: To evaluate the results of a serial pulmonary function test in severe scoliosis that required an anterior release and posterior fusion SUMMARY OF LITERACTURE REVIEW: There are a few reports on the pulmonary function after an anterior release and posterior fusion in severe scoliosis. MATERIALS AND METHODS: Twenty two cases of severe scoliosis requiring an anterior release and posterior fusion were followed up more than 2 years. The patients were divided into two groups (group 1: 10 cases of open thoracotomy and posterior fusion, group 2: 12 cases of thoracoscopic release and posterior fusion). The forced vital capacity (FVC), forced expiratory volume 1 (FEV1), total lung capacity (TLC), the predicted FVC, predicted FEV1 and predicted TLC in the preoperative, 3 month, 6 month, 1 year, 2 year postoperative period in the two groups were compared. Statistical analysis was performed using a paired T-test. RESULTS: The average preoperative FVC in groups 1 and 2 were checked as 2.20 L and 2.30 L, respectively. The postoperative 3 month FVC were checked as 1.60 L and 1.81 L, respectively, which were the lowest levels throughout the serial follow-up. The postoperative 6 month FVC were 1.70 L and 2.15 L, respectively. The postoperative 2 year FVC were 2.17 L and 2.18 L, respectively, which were 98.6% and 94.8% of the preoperative FVC. The average preoperative FEV1 of group 1 was 1.95 L. The post-operative 3 month FEV1 were at the lowest level and the postoperative 2 year FEV1 was 1.80 L (92.3% of preoperative value). The average preoperative FEV1 of group 2 was 2.05 L. The postoperative 6 month FEV1 was 1.90 L (92.7% of preoperative value). The TLC of group 2 showed a faster recovery than that of group 1. The predicted FVC, FEV1 and TLC of both groups at 2 years after surgery were 2 ~4% lower than the baseline. The recovery pattern in group 1 was steady for 2 years. The postoperative 6-month value was similar to the postoperative 2-year value in group 2. CONCLUSIONS: In severe scoliosis with a decreased pulmonary function, those undergoing thoracoscopic anterior release had a faster pulmonary function recovery than those undergoing an open thoracotomy.
