摘　　要：目的评价强直性脊柱炎(AS)后凸畸形术前截骨角度预测方法的可行性。方法 2012-04-2013-12,依据选择标准对10例AS后凸畸形患者,术前采用脊柱股骨角预测方法进行术前截骨角度设计与预测。术前、术后2周及随访时摄脊柱全长正侧位X线片和大体像,测量全脊柱后凸角(GK)、胸腰椎交界角(TLJ)、腰椎前凸角(LL)、矢状面偏移(SVA)、骨盆入射角(PI)、骶骨倾斜角(SS)、骨盆倾斜角(PT)指标,VAS、ODI评分评估患者功能改善情况。结果 GK、TLJ、LL、SVA、SS、PT、VAS、ODI术后2周和末次随访时较术前明显改善,差异有统计学意义(P<0.05)。PI术前、术后、末次随访时差异无统计学意义(P>0.05);各指标术后2周和末次随访时比较差异均无统计学意义(P>0.05)。Objective To assess the effect of a new method for calculating the exact angle re- quired for spinal osteotomy for correction of kyphosis caused by ankylosing spondylitis. Methods From April 2012 to December 2013,orthopedic patients with kyphosis caused by ankylosing spondylitis were selected based on the selection criterion in Fuyang People＇s Hospital,10 consecutive patients underwent pedieal subtraction osteotomy according to a new method for calculating the exact angle required for spinal osteotomy. The GK,TLJ,LL, SVA,PI,SS,PT,VAS, ODI were measured to evaluate the improvement at preoperation,2 weeks after operation and last follow-up. Restilts At postoperative 2 weeks and last follow-up,the GK,TLJ,LL,SVA,SS,PT,VAS,ODI were improved significantly compared with those at preoperation （P〈0.05）. But PI had no significant difference between preoperation and postoperation（P〉0.05）. Those indicators had no significant differences between .postoperative 2 weeks and last follow-up （P〉0.05）. Conclusion A new method for calculating the exact angle required for spinal osteotomy （spinofemoral angle） has satisfactory effect for the correction of kyphosis caused by ankylosing spondylitis.
