Abstract：Objective To investigate the clinical effect of percutaneous kyphoplasty (PKP) in treatment of osteoporotic vertebral fractures and collapse with intravertebral vacuum sign. Methods A retrospective study was conducted on the clinical and radiological data of 31 patients with osteoporotic vertebral fractures and collapse with intravertebral vacuum sign treated by PKP from June 2009 to June 2011. Vertebrae body variation, visual analog scale(VAS) and Oswestry disability index (ODI) before operation, during follow-up at postoperative one week and at postoperative 3-6 months were used as outcome measurements. Results All the patients went through operations successfully and presented significant mitigation of low back pain in 24 hours after operation. The vertebrae body height at postoperative one week [(17.2±4.2) mm] and at postoperative 3-6 months [(16.8±5.1) mm] were statistically different from that before operation [(11.4±1.7) mm,P＜0.01], while there was no statistical difference between the two follow-ups (P＞0.05). VAS and ODI at postoperative one week [(2.8±1.7) points and (31.6±8.4) points] were statistically different from those before operation [(8.6±1.3) points and (78.3±8.5) points, P＜0.01]. VAS and ODI at postoperative 3-6 months[(2.3±0.8) points and (23.7±2.3) points] presented statistical differences from those before operation (P＜0.01), but no statistical differences from those at postoperative one week (P＞0.05). Conclusion PKP obtains satisfactory clinical outcomes, for it relieves low back pain and restores vertebral body height.
