Fourteen patients with ankylosing spondylitis had an extension osteotomy for severe flexion deformity of the spine. The Smith-Petersen technique was modified by using a compression device which allows a slow, finely controlled closure of the osteotomy, and provides rigid internal fixation. There were no serious neurological complications. All the patients were able to see straight ahead after operation, and all had solid fusion at nine months, having maintained good correction.
14例强直性脊柱炎患者因脊柱严重屈曲畸形接受了伸展截骨术。对Smith-Petersen技术进行了改良，使用了一种加压装置，该装置可实现截骨部位缓慢、精确控制的闭合，并提供坚固的内固定。未出现严重的神经并发症。所有患者术后均能直视前方，9个月时均实现了牢固融合，且维持了良好的矫正效果。
