经皮椎体后凸成形术治疗Kummell病的疗效

Efficacy of percutaneous kyphoplasty for Kummell disease

目的观察经皮椎体后凸成形术(PKP)治疗创伤后迟发性椎体骨坏死(Kummell病)的临床疗效。方法确诊Kummell病患者16例,行PKP治疗,比较手术前后椎体前缘高度、Cobb角及VAS评分。结果 16例患者获得随访(19.7±6.3)个月。术后病椎前后缘高度比值较术前增加[(90.3±1.4)%vs.(70.2±1.5)%](P<0.01),Cobb角较术前降低[(1.82±0.65)度vs.(6.72±2.05)度](P<0.01),VAS评分较术前减少[(2.5±1.9)分vs.(8.8±2.1)分](P<0.01)。术中1例发生骨水泥渗漏,但未出现神经症状。结论 PKP治疗Kummell病临床疗效满意。

Objective To observe the clinical efficacy of percutaneous kyphoplasty（PKP） for Kummell disease. Methods Sixteen patients with confirmed Kummell disease underwent PKP. The ratio of anterior to posterior height of vertebral body on X-ray,Cobb＇ s angle and VAS pain score were compared before and after surgery. Results The patients were followed up for （19.7±6. 3） months. The ratio of anterior to posterior height of vertebral body was higher after operation than that before [（90. 3± 1.4） % vs. （70. 2 ± 1.5） %] （P〈0. 01）. Cobb＇ s angle was less after operation than that beforeF（1.82±0. 65） degrees vs. （6.72 ± 2. 05） degrees] （P〈0. 01）. VAS pain score was less after operation than that before [（2. 5 ± 1.9） points vs. （8. 8 ± 2.1） points] （P〈0. 01）. Bone cement leakage during operation happened in one case, which did not produce any symptom of acute spinal cord compression. Conclusion The clinical efficacy of PKP for Kummell disease is satisfactory.
