- W2386718163 abstract "Objective To investigate the optimal operation time of percutaneous kyphoplasty( PKP) for osteoporotic vertebral compression fractures( OVCFs) and the prevention of its complications. Methods From Jan.2010 to May 2012,PKP operation was performed for 73 OVCFs patients. Twenty-eight cases( 32 vertebral bodies)who took surgical treatment at 1 week after injury were regarded as the early operation group( group A),and forty-five cases( 57 vertebral bodies) who took operation more than 4 weeks after injury were taken as the delayed operation group( group B). The Cobb angle and anterior vertebral height of all patients preoperatively,postoperatively and at 12months after follow-up were compared between the two groups. The visual analogue scale( VAS) was used for the pain assessment. Results Group A: the average amount of bone cement injected into each vertebral body was( 5. 2 ±1. 3) ml,the improvement rate of VAS score was( 78. 5 ± 12. 1) %,the improvement rate of Cobb Angle was( 51. 1 ±9. 2) %,the improvement rate of anterior height of the injured vertebra was( 72. 6 ± 6. 4) %. Group B: the average amount of bone cement injected into each vertebral body was( 3. 6 ± 0. 9) ml,the improvement rate of VAS score was(54. 5 ±10. 6) %,the improvement rate of Cobb was(46. 1 ±9. 2) %; the improvement rate of anterior height of the injured vertebral body was( 49. 5 ± 5. 1) %. The VAS scores at 12 months after operation in the two groups were( 1. 4 ±0. 5) and(1. 6 ±0. 4),respectively,without significant differences between the two groups. In group A,vertebral refracture occurred in 2 cases. The improvements of VAS score,Cobb Angle and anterior height of the injured vertebral body were better than those in group B( P 0. 05),while the bone cement leakage rate was lower than that in group B. Conclusion PKP is an effective method for OVCFs. Early surgical treatment can reduce patients' pain rapidly and significantly,and it can better restore the vertebral shape than delayed surgical treatment. Controlling the viscosity of bone cement and taking fluoroscopic images while injecting can reduce leakage of bone cement." @default.
