经皮椎体后凸成形治疗骨质疏松性椎体压缩骨折后脊柱-骨盆矢状位平衡变化及其与生存质量的相关性

摘要

目的 探讨骨质疏松性椎体压缩骨折患者经皮椎体后凸成形术后脊柱-骨盆矢状位平衡变化及其与生存质量的相关性.方法 回顾纳入并筛选2012年1月至2016年12月于同济大学附属东方医院脊柱外科因骨质疏松性椎体压缩骨折(OVCF)接受经皮椎体后凸成形(PKP)手术治疗的腰椎单椎体压缩骨折资料完整的85例患者.术前、出院前及随访时行脊柱全长正侧位X片检查.全长侧位片上测得脊柱-骨盆参数有:矢状位平衡(C7SVA),胸椎后凸角(TK),腰椎前凸角(LL),骨盆入射角(PI),骨盆倾斜角(PT),骶骨倾斜角(SS),并问卷健康调查简表(SF-36)评分.结果 PKP术后末次随访时C7SVA由(35.9 ± 17.1)mm降至(30.8 ± 12.8)mm(P=0.002).SF-36各个角色评分均发生显著变化(P<0.01).PKP术前、术后3 d、6个月及12个月随访时,C7SVA与SF-36中总体健康呈显著负相关(r=-0.343,-0.264,-0.272,-0.258;P=0.001,0.015,0.012,0.017).结论 PKP手术能有效治疗OVCF,并能改变OVCF患者脊柱-骨盆矢状位平衡;且该类患者脊柱-骨盆矢状位平衡与生存质量密切相关.%Objective To explore the correlation between spinal sagittal balance and quality of life after the treatment of percutaneous kyphoplasty in osteoporotic vertebral compressive fractures. Methods We retrospec-tively enrolled and screened 85 patients with osteoporotic vertebral compression fractures(OVCF),treated by per-cutaneous kyphoplasty(PKP)in spinal surgery department of Shanghai East Hospital from January 2012 to Decem-ber 2016. The full length of the spine X-ray examinations had been taken preoperatively,pre-discharge and during the follow-up and spine-pelvis sagittal parameters included C7 sagittal vertical axis(C7SVA),thoracic kyphosis (TK),lumber lordosis(LL),pelvic incidence(PT)and sacral slope(SS). Shot Form 36 Health Survey Question-naire(SF-36)was used for the scoring. Results In the last follow-up,C7SVA decreased from(35.9 ± 17.1)mm to(30.8 ± 12.8)mm(P=0.002)and SF-36 scores varied significantly(P<0.01). Before the surgery,follow-up 3 days,6 months and 12 months after the surgery,C7SVA was negatively correlated with the general health status in each period of SF-36(r=-0.343,-0.264,-0.272,-0.258;P=0.001,0.015,0.012,0.017). Conclusions PKP has a significant effect on OVCFs and changes the spine-pelvic sagittal balance in patients with OVCF. Spinal-pel-vic sagittal balance is closely related to the quality of life of these patients.
