Abstract:
Objective:To evaluate the clinical efficacy of SKy bone expander system in percutaneous kyphoplasty for treat- ment of osteoporotie verterbral compression fracture.Methods:Twenty-two patients(aged 62-90 years,32 vertebrae)under- went percutaneous kyphoplasty using SKy bone expander system.The bone cement was injected into the collapsed vertebrae. The vasual analogue scale(VAS)and complications were recorded during follow up.Results:The operations were successful in all patients via unilateral or bilateral approach.The operation time ranged from 30 to 120 min.The mean volume of cement in- jected into each vertebra body was(4.8?1.1)ml,ranged from 3.1 to 6.8 ml.Extravertebral leakage of bone cement was ob- served in two vertebrae with no symptoms.All patients had their pain relieved;the VAS was 7.6?0.8 before operation,3.5?0.5 one day after operation,2.8?0.6 one week after operation,and 2.4?0.6 one month after operation,with significant difference found between preoperation and postoperation(P
