| ObjectiveTo observe the clinical efficacy of the treatment of ostcoporotic vertebral compression fractures (OVCF) with the method of percutaneous kyphoplasty (PKP) with balloon system.Methods24vertebral bodies in21patients with ostcoporotic vertebral compression fractures were treated by PKP with balloon system during Octouber2010to February2012in the second affiliated hospital of Zhengzhou University. In these cases there were6male patients and15female patients with the mean age was74.3years. The vertebral bodies contained2T8,2T11,6T12,10L1,3L2and1L3.The anterior vertebral height and Cobb angle was measured in each vertebral body before and after PKP to evaluate the efficacy of PKP in spinal alignment.The visual analogue scores(VAS) and the Oswestry disability index (ODI) of every patient was observed before PKP,24hours after PKP and a week after PKP to evaluate the efficacy of PKP in pain relief and promoting the quality of life. ResultsAll the operations were successfully on the21cases with no symptomatic complications. The mean anterior vertebral height and Cobb angle was13.43±2.53mm and (21.24±3.58)°before PKP,22.34±1.92mm and (12.12±2.68)°after PKP, the differences between postoperation and preoperation were statistically significant(P<0.05). The VAS and ODI was mean7.32±1.73point and90.26±1.32before operation,2.83±1.32point and34.27±2.5324hours after operation and2.71±1.53point and31.13±1.68a week after PKP. The ODI and VAS between preoperation and one day or one week after operation had statistically significant differences (P<0.05).But there was no difference between one day and one week after PKP.ConclusionPercutaneous kyphoplasty with balloon system can recover the height and correct the kyphosis of the vertebral body with OVCF effectively and promote the quality of life, is a safe and effective treatment method for vertebral compression fractures. |
