文题释义:
经皮球囊扩张椎体后凸成形术(percutaneous kyphoplasty,PKP):是治疗骨质疏松性椎体压缩骨折的一种新方法,即通过经皮穿刺向椎体内放置可膨胀性气囊(IBT),扩张后再注入骨水泥。PKP手术不仅可以迅速缓解患者疼痛症状,而且可以部分恢复被压缩椎体的高度,矫正椎体后凸畸形,增强椎体的强度和硬度,提高术中灌注骨水泥的安全性。
骨质疏松性椎体压缩性骨折:是因椎体骨基质中钙盐沉积量减少,导致骨组织微细结构破坏、强度下降、脆性增加,轻微应力及损伤即可诱发的椎体骨折,是骨质疏松严重的并发症之一。
 
摘要
背景:已有一些研究分析了经皮球囊扩张椎体后凸成形后再骨折的高危因素,但对经皮球囊扩张椎体后凸成形后椎体再骨折的高危风险因素及干预措施尚存有争议。
目的:分析经皮球囊扩张椎体后凸成形后椎体再骨折的风险因素,探讨针对性的风险因素干预在预防经皮球囊扩张椎体后凸成形后再骨折中的应用价值。
方法:纳入骨质疏松性椎体压缩性骨折患者,2009年4月至2011年4月接受经皮球囊扩张椎体后凸成形治疗的60例作为A组,采用Logistic多因素分析经皮球囊扩张椎体后凸成形后再次椎体骨折的高危因素,并针对高危因素制定相应的干预措施;2013年5至2015年5月60例接受经皮球囊扩张椎体后凸成形治疗的患者,作为B组,接受针对性干预处理(对患椎邻近存在椎体真空裂隙征的椎体,予以预防性注入骨水泥;服用抗骨质疏松药物,并进行健康用药指导等),术后随访记录并比较两组椎体再骨折发生率等情况。
结果与结论:①A组术后平均随访18个月,21例再次发生骨折,38例未发生骨折;B组10例患者再次出现椎体骨折,B组2年无事件生存时间显著长于A组(P=0.015);②Logistic多因素模型分析结果显示,术前骨密度T值、抗骨质疏松治疗依从性、糖皮质激素用药史、术中骨水泥渗漏及椎体裂隙征是影响经皮球囊扩张椎体后凸成形后再次骨折的独立因素(P < 0.05);③经ROC分析显示,术前骨密度T值和抗骨质疏松依从性评分预测患者经皮球囊扩张椎体后凸成形后再次骨折的AUC分别为0.772和0.693(β=0.064,0.067,95%CI=0.646-0.898,0.562-0.823,P=0.001,0.014),最佳截断值分别为-3.74和4.53分,敏感度分别为0.795和0.81,特异度分别为0.762和0.59;④结果说明,经皮球囊扩张椎体后凸成形后重视术前骨密度、术后抗骨质疏松治疗依从性、糖皮质激素用药史等高危风险因素警示作用,给予针对性干预有助于降低术后再骨折发生率,改善预后。

Abstract:

BACKGROUND: Risk factors for vertebral re-fracture after percutaneous kyphoplasty (PKP) have been studied, but have not been confirmed, and the treatment measurements remain controversial.

OBJECTIVE: To analyze the risk factors for vertebral re-fracture after PKP and to explore the application value of targeted risk factor intervention in the prevention of re-fracture after PKP.
METHODS: Totally 60 patients with osteoporotic vertebral compression fractures from April 2009 to April 2011 treated with PKP were used as group A. The risk factors for vertebral re-fracture after PKP were evaluated by Logistic multivariate analysis, and the targeted risk factor intervention was designed. Sixty patients with osteoporotic vertebral compression fractures from May 2013 to May 2015 undergoing PKP served as group B, and treated with targeted intervention (injecting bone cement into the nearby vertebrae with intravertebral vacuum cleft; administrating antiosteoporosis drug, and receiving medication guidance). The postoperative incidence of re-fracture was recorded and compared between two groups.
RESULTS AND CONCLUSION: (1) After followed up for 18 months postoperatively, in the group A, there were 21 cases of re-fracture and 38 cases of none-fracture. In the group B, there were 10 patients with re-fracture. The survival time in 2 years without adverse event in the group B was significantly longer than that in the group A (P=0.015). (2) The results of Logistic multivariate model analysis showed that the T score of bone mineral density at baseline, compliance of anti-osteoporosis treatment, history of glucocorticoid, postoperative bone cement leakage and intravertebral vacuum cleft were independent factors for re-fracture after PKP (P < 0.05). (3) The ROC analysis showed that the preoperative T score of bone mineral density and compliance of anti-osteoporosis treatment predicted that the AUC of re-fracture after PKP were 0.772 and 0.693 respectively (β=0.064, 0.067; 95%CI=0.646-0.898, 0.562-0.823; P=0.001, 0.014). The best cut-off values were -3.74 and 4.53 scores respectively, the sensitivities were 0.795 and 0.81, respectively, and the specificities were 0.762 and 0.59 respectively. (4) These results indicate that we should pay more attentions for prediction role of high risk factors (including preoperative bone mineral density, compliance of postoperative anti-osteoporosis treatment, and history of glucocorticoid), and giving targeted interventions will reduce the incidence of postoperative fracture and improve the prognosis.
