驼背二种截骨术远期效果对比

Comparison of Long term Operative Results of Kyphosis of Ankylosing Spondylitis Managed by Two Osteotomy Methods

作者对６３２例强直性脊柱炎并驼背畸形施行二种脊柱截骨矫治术，对其中１３５例病人进行了６～１０年观察，结果表明：７１例椎弓椎体联合截骨效果较好，驼背复发平均３．２°。而６４例椎板截骨效果略差，驼背平均复发１３．５°。经统计学处理，两者对比有显著的统计学意义（ｐ＜０．０１）。作者认为病变未完全静止，截骨术式的选择，术中身体重心前移未彻底纠正，以及外固定时间过短等是影响远期效果的因素。

Two different osteotomy methods were used for the operative correction of kyphosis of ankylosing spondylitis.Of 632 cases operated on,135 were followed up from 6 to 10 years.excellent results were achieved in 71 patients who had been operated on by transpedicular vertebral body osteotomy. The mean relapse was 3.2°(Cobb′s angle),while the results of the 64 patients who had been operated by translaminal osteotomy with mean relapse being 13 5°.These two results were statisticaly significant(P<0 01).The incomplete silence of the pathological process,selection of the osteotomy methods,insuffecient correction of anterior displacement of the body gravity center and time insufficency of postoperative external immobilization were factors involving the long term results.
