椎体后凸成形术与保守治疗骨质疏松性脊柱骨折的对比研究

目的通过临床对比研究分析椎体后凸成形术治疗骨质疏松性脊柱骨折的临床疗效。方法 2006年3月-2007年8月,收治60例骨质疏松性脊柱骨折患者。其中40例选择椎体后凸成形术治疗(试验组),20例选择保守治疗(对照组)。试验组:男6例,女34例;年龄56～78岁,平均68.7岁。病程10～18个月,平均12个月。骨折涉及73个椎体。对照组:男5例,女15例;年龄57～80岁,平均70.1岁。病程9～16个月,平均13个月。骨折涉及41个椎体。两组患者性别、年龄、病程、疼痛视觉模拟评分(VAS)、欧洲脊柱骨质疏松症研究(EVOS)问卷评分,以及伤椎前中柱椎体高度、后凸Cobb角比较,差异均无统计学意义(P>0.05),具有可比性。结果试验组患者术后切口均Ⅰ期愈合,无骨水泥渗漏。两组患者均获随访,随访时间36～38个月。试验组治疗后1～3 d及12、36个月VAS评分、EVOS评分、伤椎前中柱椎体高度及后凸Cobb角均较术前明显改善(P<0.05);对照组治疗后以上指标与术前比较无改善(P>0.05)。治疗后12、36个月,试验组以上指标均优于对照组(P<0.05)。治疗后36个月,对照组患者新发脊柱骨折发生率高于试验组(χ2=16.347,P=0.015)。结论椎体后凸成形术治疗骨质疏松性脊柱骨折后,疼痛症状可明显缓解,活动功能恢复,且新发脊柱骨折发生率较保守治疗低。

COMPARISON OF EFFECTIVENESS BETWEEN KYPHOPLASTY AND CONSERVATIVE TREATMENT IN TREATING OSTEOPOROTIC VERTEBRAL FRACTURES

Objective To investigate the effectiveness of kyphoplasty in treating osteoporotic vertebral fracture according to comparative study.Methods Between March 2006 and August 2007,60 patients with osteoporotic vertebral fractures were treated.Kyphoplasty was performed in 40 patients(test group) and conservative treatment was performed in 20 patients as control(control group).In test group,there were 6 males and 34 females with an average age of 68.7 years(range,56-78 years).The disease duration was 10-18 months...
