摘要
目的:探讨后路截骨矫形固定融合术治疗强直性脊柱炎(ankylosingspondylitis,AS)假关节并后凸畸形的可行性。方法:30例AS患者,年龄29￣55岁,平均41.7岁,行后路张开式楔形截骨矫正后凸畸形及内固定,平均随访4.7年(2.2￣9.1年),根据影像学资料、临床结果与并发症情况评估治疗效果。结果:3例术前有神经压迫症状患者术后均得到改善。脊柱后凸Cobb角从平均45.5°(37°￣68°)矫正到7.5°(0°￣4°),平均矫正38°。随访时假关节处均已融合,矫正无明显丢失,亦无严重并发症发生。结论:后路张开式楔形截骨矫形内固定融合是治疗AS并假关节和脊柱后凸畸形的有效方法,不需施行前路骨融合手术即可达到假关节处的骨融合。
Objective：To assess the effectiveness of posterior correction and fixation fusion for pseudoarthrosis with kyphosis in patients with ankylosing spondylitis（AS）. Method：Thirty consecutive patients with AS（mean age 41.7 years,range 29-55 years old） underwent posterior correction and fixation without anterior fusion to treat pseudoarthmsis with kyphosis. Mean follow-up was 4.7 years （range 2.2-9.1 years）. Radiographic and clinical results and complications were kyphosis was substantially corrected from 45.5° （37°-68°） to 7.5°0°-14°） ,with a mean correction of 38°.All patients had no evidence of nonunion on X-ray at the level of the pseudoarthrosis at final follow-up.None had a notable loss of correction.No major complication occurred.Three patients with neurologic deficits had postoperative improvement.Conclusion：Posterior correction and fixation is effective for managing pseudoarthrosis with kyphosis in AS,anterior fusion procedure is not necessary.
