椎弓根外穿刺行单侧PVP或PKP术治疗上中位胸椎椎体骨折

目的:探讨椎弓根外穿刺行单侧PVP或PKP术治疗上中位胸椎骨质疏松性压缩骨折(OVCFs)的特点与疗效。方法:回顾性分析2004年11月～2010年3月我院收治的上、中胸椎OVCFs患者26例39个椎体,均采用椎弓根外穿刺行单侧PVP或PKP术,其中男8例,女18例;平均年龄71.3±1.3岁;原发性OVCFs 19例,继发OVCFs 7例。骨折时间平均3.5周,骨折椎体分布:T3 1个、T4 3个,T5 4个,T6 4个,T7 6个、T8 10个、T9 6个、T10 5个。1个节段17例,2个节段5例,3个节段4例。PVP 15例27个节段,PKP 11例12个节段。术中观察穿刺针针尖达到椎体中线的比率,术后1d及末次随访时测量骨折椎体前缘和椎体中间高度的恢复值、VAS评分的改善率、骨水泥向椎体外渗漏率以及患者的满意度。结果:39个椎体均经单侧胸椎椎弓根外途径穿刺完成PVP和PKP操作。均穿刺成功、骨水泥在椎体内左右对称分布。手术时间为25～35min/椎,无穿刺并发症。骨水泥平均注射量3.5ml/椎。骨水泥渗漏4例,渗漏率10.25%。平均随访时间14个月。VAS评分术前平均为9.8±0.3分,术后1d平均为5.7±0.4分,末次随访时为3.3±0.4分,术前与术后1d及末次随访时的VAS评分比较,疼痛均得到了明显改善(P<0.05);椎体前缘高度恢复值和椎体中间高度恢复值分别为为63.1±18.6%和68.5±25.3%,均较术前明显恢复(P<0.05)。患者对治疗的满意率达100%。结论:治疗上、中位胸椎骨质疏松性压缩性骨折,椎弓根外穿刺行单侧PVP和PKP术是一种安全、可行和有效的治疗方法。

Unilateral extrapedicular vertebroplasty and kyphoplasty in the treatment of upper and mid-thoracic vertebral compression fracture

Objective:To evaluate the characteristics and effects of unilateral extrapedicular vertebroplasty and kyphoplasty in the treatment of upper and mid-thoracic vertebral fractures.Methods:Retrospective analysis of 39 vertebrae in 26 patients(M:F=8:18)who underwent unilateral extrapedicular vertebroplasty and kyphoplasty for osteoporotic vertebral compression fractures at upper and mid-thoracic vertebra between November 2004 and March 2010 in our hospital.The fracture vertebras is T3 1,T4 3,T5 4,T6 4,T7 6,T8 10...
