经皮椎体后凸成形术治疗老年骨质疏松胸腰椎压缩性骨折的临床观察

目的观察经皮椎体后凸成形术(percutaneous kyphoplasty,PKP)治疗骨质疏松性脊柱压缩性骨折的临床疗效。方法 13例22椎老年骨质疏松性脊柱骨折患者采用PKP治疗,统计手术前后椎体前缘、中部高度丢失率,后凸畸形Cobb角,疼痛视觉模拟评分(VAS)、日常生活活动能力评分(Barthel指数)等指标,评价治疗效果。结果所有患者术后腰部疼痛完全或明显缓解,均恢复伤前生活方式;术后椎体高度较术前明显恢复;后凸畸形Cobb角较术前改善明显。均无并发症发生。结论 PKP是治疗老年骨质疏松脊柱压缩骨折安全有效的方法。

Clinical efficacy of percutaneous kyphoplasty for treatment of vertebral compression fractures in senile osteoporosis

Objective To study the clinical efficacy of percutaneous kyphoplasty （PKP） for treatment of osteoporotic vertebral compression fractures. Methods Thirteen senile patients （22 vertebrae） with osteoporotic vertebral compression fractures underwent percutaneous kyphoplasty. Parameters including percentage height loss at the anterior and middle parts of vertebral body, Cobb angle of deformed kyphosis, visual analogue scale （VAS）, and performance in daily activities （Barthel Scale） were measured to evaluate the efficacy of PKP. Results All patients experienced complete or significant relief of back pain and resumed their pre-injury life. The height of vertebral body was restored; and Cobb angle of kyphosis improved significantly. There were no complications noted. Conclusion Percutaneous PKP can be a safe and effective treatment for vertebral compression fractures in senile osteoporosis.
