Objective To analyze clinical effect by bilateral percutaneous puncture kyphoplasty in the treatment of Kummell's disease. Methods A total of 36 patients with Kummell’s disease received bilateral percutaneous puncture kyphoplasty for treatment. Evaluation of their curative effects was made through comparing anterior vertebral edge height, local sagittal Cobb angle and visual analogue scale (VAS) score before and after operation. Results There were no adverse reactions of bone cement, cardiovascular and cerebrovascular accidents, spinal injury and nerve injury in all 36 patients during operation. VAS scores in follow-up after 24 h, 3 months of operation and final follow-up were respectively (1.59±0.80), (1.35±0.61) and (1.24±0.66) points, which were all lower than (5.59±0.80) points before operation, and their difference had statistical significance (P<0.05). Anterior vertebral edge height ratio were respectively (88.1±7.3), (87.8±6.8) and (86.8±6.5)%, which were all higher than (29.1±6.7)% before operation, and the difference had statistical significance (P<0.05). Sagittal Cobb angle after operation was smaller than before operation. Conclusion Bilateral percutaneous puncture kyphoplasty shows small trauma and few complications. As an excellent surgical way in treating Kummell’s disease, it can eliminate micro fracture shift, provide sufficient biomechanical support, and resume stability of spine.%目的：分析双侧经皮穿刺椎体后凸成形术治疗 Kummell 病的临床疗效。方法36例Kummell 病患者，采用双侧经皮穿刺椎体后凸成形术治疗，通过比较手术前后椎体前缘的高度比、局部矢状位 Cobb 角及疼痛视觉模拟评分法(VAS)进行疗效评定。结果36例患者术中无骨水泥不良反应及心、脑血管意外发生，无脊髓、神经损伤。术后24 h、术后3个月及末次随访时， VAS 评分分别为(1.59±0.80)、(1.35±0.61)、(1.24±0.66)分，均小于术前的(5.59±0.80)分，差异具有统计学意义(P<0.05)；伤椎前缘高度比分别为(88.1±7.3)、(87.8±6.8)、(86.8±6.5)%，均高于术前的(29.1±6.7)%，差异具有统计学意义(P<0.05)。术后患者的伤椎矢状位 Cobb 角均小于术前，差异具有统计学意义(P<0.05)。结论经皮穿刺椎体后凸成形术创伤小、并发症少，能够消除椎体骨折处的微动，提供足够的生物力学支撑，恢复脊柱的稳定性，是治疗 Kummell 病较好的手术方式。
