经皮椎体成形术在创伤性椎体压缩骨折中的应用

Application of percutaneous vertebroplasty in traumatic vertebral compression fractures

目的探讨外伤性椎体压缩骨折经皮椎体成形术（PVP）的技术操作和临床疗效。方法对25例创伤性椎体压缩骨折患者共39个椎体在X线数字减影血管造影（DSA）监视下行PVP。结果 25例手术全部成功,注入Ⅲ型丙烯酸树脂骨水泥2~5 mL,平均3.5 mL,骨水泥渗漏率为17.9%（7/39）,均未发生神经压迫症状,术后3个月随访显示症状完全缓解84%,部分缓解8%,轻微缓解8%。结论采用PVP治疗创伤性椎体压缩骨折疗效显著,操作简便,值得临床推广应用。

Objective To explore technological operation and clinical therapeutic effects of percutaneous vertebroplasty（PVP） in traumatic vertebral compression fractures.Methods PVP was performed under X-ray digital subtraction angiography（DSA） monitoring in 25 patients with traumatic vertebral compression fractures in 39 vertebrae.Results All 25 cases of PVP were successful.Injection volume of acrylic bone cement type Ⅲ was 2-5 mL,an average of 3.5 mL,permeability of bone cement was 17.9%（7/39）,with no symptoms of nerve compression occurred.The follow-up visit revealed that 84% patients had shown complete remission of symptoms three months after operation,with 8% of patients showing partial remission and 8% slight remission.Conclusion In treatment of traumatic vertebral compression fractures,PVP is an notably efficient,easy and convenient operation which worth being recommended.
