BACKGROUND Kümmell's disease is a special type of osteoporotic vertebral fracture that causes chronic low back pain and deformity, which seriously affects the living quality of patients. PVP is commonly used to treat osteoporotic vertebral fractures and can quickly relieve low back pain. So, the objective of this study was to analyze the clinical efficacy and experience of bipedicular percutaneous vertebroplasty combined with postural reduction for the treatment of Kümmell's disease. METHODS A retrospective analysis of patients with Kümmell's disease who underwent bipedicular percutaneous vertebroplasty was conducted from February 2016 to May 2018. Operative time, VAS, bone cement injection volume, cement leakage rate, compression improvement of vertebral front edge and vertebral center, and correction degree of kyphosis were collected and analyzed meticulously. RESULTS The operative time was 45.33 ± 7.64 min. The volume of bone cement injected was 5.38 ± 1.33 ml. The compression improvement of vertebral front edge was 7.31 ± 1.21%. The compression improvement of vertebral center was 10.34 ± 1.15% and the correction degree of kyphosis was - 2.73 ± 0.31゜. Bone cement leakage occurred in 6 of 39 patients (15.38%), but no clinical symptoms were observed. The VAS scores were significantly lower at 1 day after the surgery, 6 months and at the last follow-up than before the surgery (P = 0.000, respectively). The VAS score was lower at the last follow-up than at 1 day after the surgery (P = 0.001). CONCLUSION Bipedicular percutaneous vertebroplasty combined with postural reduction could achieve satisfactory analgesic effect in the treatment of Kümmell's disease, and restore the height of the vertebral body and improve kyphosis to some extent.

双蒂经皮椎体成形术联合体位复位治疗库梅尔病的临床疗效和经验。

背景技术库梅尔氏病是一种特殊类型的骨质疏松性椎体骨折，会引起慢性下腰痛和畸形，严重影响患者的生活质量。PVP通常用于治疗骨质疏松性椎体骨折，可以快速缓解腰痛。因此，本研究的目的是分析双蒂经皮椎体成形术联合体位复位治疗库梅尔氏病的临床疗效和经验。方法回顾性分析2016年2月至2018年5月接受双蒂经皮椎体成形术治疗的Kümmell病患者的临床资料。收集并仔细分析驼背的矫正度。结果手术时间为45.33±7.64min。注入的骨水泥的体积为5.38±1.33ml。椎骨前缘的压缩改善为7.31±1.21％。椎体中心的压缩改善为10.34±1.15％，驼背矫正度为-2.73±0.31゜。39例患者中有6例发生骨水泥渗漏（15.38％），但未观察到临床症状。术后1天，6个月和最后一次随访时，VAS评分显着低于手术前（分别为P = 0.000）。在最后一次随访中，VAS评分低于手术后1天（P = 0.001）。
