经皮球囊扩张椎体后凸成形术治疗骨质疏松性椎体压缩骨折的临床疗效分析

目的 探讨经皮球囊扩张椎体后凸成形术（PKP）治疗老年骨质疏松性椎体压缩骨折的临床疗效。方法 回顾性分析2014年1月~2015年1月经PKP治疗骨质疏松性椎体压缩骨折患者100名，男性74例，女性26例，患者年龄62~86岁，平均年龄73.5岁。病程1~15天，骨折椎体范围为T₇~L₄，其中单椎体76例，双椎体24例。记录患者术前与术后VAS、JOA评分、Cobb角变化情况，评价临床疗效。结果 术后随访时间6~12个月，平均8个月，患者VAS、JOA评分、及Cobb角术前分别为8.25±1.85、12.35±6.05、25.30°±5.60°，术后12h分别为1.25±0.45、23.20±2.20、12.20°±2.56°，术后所有患者胸腰背部疼痛均明显缓解或消失，所有患者均未发现椎间隙骨水泥渗漏或椎管内骨水泥渗漏情况。结论 PKP可显著缓解腰背疼痛，减少腰背后凸畸形，增强椎体稳定性，是治疗老年骨质疏松性椎体压缩骨折的有效方法。

Clinical Effect of Percutaneous Kyphoplasty in Treatment of Osteoporotic Vertebral Body Compression Fractures

Objective To evaluate the clinical efficacy of percutaneous kyphoplasty(PKP) in surgical treatment of osteoporosis thoracolumbar vertebral compression fracture in elderly.Methods Retrospective analysis from January 2014 to January 2015 was performed. 100 cases(74males and 26 females;62-86 years of age,mean 73.5 years)of osteoporosis vertebral compression fracture were treated with PKP. Lesion involved in compressed vertebral located in the T7-L4 segment duration from one day to fifteen days. Treatment effects were assessed with Japanese Orthopedics Association (JOA) Score, Cobb angle and visual analogue score(VAS).Results The follow-up was 6-12 months (mean 8 months). After 12 hours of operation, improvements were observed in VAS[(8.25±1.85) points vs (1.25±0.45) points],JOA[(12.35±6.05) points vs (23.20±2.20) points], and Cobb angle[(25.30±5.60)° vs (12.20±2.56)°]. Thoracic back pain significantly alleviated or disappeared. All patients were not found in intervertebral spinal bone cement leakage or leakage into the spinal canal.Conclusion PKP is an effective method for treatment of osteoporotic vertebral compression fracture in the elderly, for it can reduce back kyphosis, increase vertebral stability and relieve thoracic back pain.
