Abstract

To evaluate pulmonary function changes in patients with severe scoliosis undergoing anterior release, posterior segmental fixation and fusion, and convex thoracoplasty by resecting a short length of rib. From January 2006 to July 2007, 16 patients with severe scoliosis were treated with anterior release, posterior segmental fixation and fusion, and convex thoracoplasty by resecting a short length of rib. There were 6 males and 10 females with an average age of 16.9 years (range, 10-24 years). There were 1 case of Lenke 1 curve, 9 cases of Lenke 2 curve, and 6 cases of Lenke 4 curve. The preoperative Cobb angle was (104.8 +/- 10.9) degrees and the preoperative thoracic kyphotic angle was (30.0 +/- 4.2) degrees. The preoperative height of "razor back" deformity was (5.9 +/- 1.2) cm. Before operation, the actual value of forced vital capacity (FVC) was (2.04 +/- 0.63) L and that of forced expiratory volume in 1 second (FEV1.0) was (1.72 +/- 0.62) L. The percentage of actual values to expected ones in FVC was 70% +/- 16%, and that in FEV1.0 was 67% +/- 15%. All patients had pulmonary function tests before operation and 3, 6, 12, 24 months after operation. All wounds healed by first intention. The Cobb angle at 24-month follow-up wa...Continue Reading
