摘要
[目的]评价术前Bending位X线片对退变性脊柱侧凸(degenerative scoliosis,DS)术后矫形效果的预测能力,并比较Bending位X线片对预测单纯后路矫形与后路截骨矫形手术效果的差异。[方法]65例接受脊柱矫形手术的DS患者纳入研究,选取每位患者的站立位全脊柱正位X线片、Bending位X线片,术后立位全脊柱正位X线片,分别在以上三种X线片上测量侧凸主弯的Cobb角,分析术前Bending位片Cobb角与术后立位片Cobb角及弯曲柔韧性(BF)与矫形率(CR)的相关性;根据是否行截骨术,将65例患者分为37例单纯后路矫形组与28例伴截骨矫形组,分别分析两组术前Bending位X线片Cobb角与术后立位片Cobb角以及BF与CR相关性。[结果](1)65例患者术前Bending位X线片Cobb角与术后立位X线片Cobb角具有明显相关性(r=0.652,P<0.001),BF与CR具有明显相关性(r=0.451,P<0.001),平均CR为(62.22±14.50)%;(2)37例单纯后路矫形患者术前Bending位片Cobb角与术后立位片Cobb角具有明显相关性(r=0.772,P<0.001),BF与CR具有明显相关性(r=0.729,P<0.001),平均CR为(60.36±14.98)%;28例伴有截骨矫形患者术前Bending位X线片Cobb角与术后立位X线片Cobb角具有相关性(r=0.596,P=0.001),BF与CR相关性差(r=0.237,P=0.225),平均CR为(64.66±13.73)%。[结论]术前Bending位X线片可以预测退变性脊柱侧凸术后矫形效果,其预测单纯后路矫形效果的能力明显优于后路截骨矫形效果的能力。
[Objective] To assess the prediction value of bending X- ray film for the correction of degenerative scoliosis（ DS）. [Methods] Sixty- five DS patients having received posterior surgery in our institution were included. Of all the patients,37 received posterior surgery alone and 28 received posterior osteotomy surgery. For all patients,pre- operative standing X- ray film, bending X- ray films and post- operative standing X- ray film were performed, and Cobb angle was measured. Pearson＇s correlation was used to determine the relationship between pre- operative bending Cobb angle and post-operative standing Cobb angle. Correlation between bending flexibility（ BF） with correction rate（ CR） was also evaluated. Prediction values of the X- ray film for the two groups were comparatively studied. [Results] For all 65 subjects,pre-operative bending Cobb angle was correlated with post- operative Cobb angle（ r = 0. 652,P〈0. 001） and BF was correlated with CR（ r = 0. 451,P〈0. 001）. For patients received posterior surgery alone,there was a significant correlation of pre- operative bending Cobb angle with post- operative Cobb angle（ r = 0. 772,P〈0. 001）,and there was also a correlation of BF with CR（ r = 0. 729,P〈0. 001）. For patients received posterior osteotomy surgery,there was a correlation of pre- operative bending Cobb angle with post- operative Cobb angle（ r = 0. 596,P = 0. 001）,while there was no significant correlation of BF with CR（ r = 0. 237,P = 0. 225）. [Conclusion] Pre- operative bending X- ray film can predict the outcome of correction of DS,and its prediction power is superior in patients receiving posterior surgery alone than those receiving posterior osteotomy surgery.
