| Objective To investigate the characteristics and associated riskfactors of refracture after percutaneous kyphoplasty.Methods We retrospectively reviewd patients with osteoporoticcompression fractures from May2011to December2012.There were106patients,including21males and85females.The age ranged from52yearsto90years,with an average of71.3years.The patients receivedpercutaneous kyphoplasty with bone cement augmentation.Theradiographical follow-up identified the occurrence of vertebral fractureafter the initial vertebral fracture.Results In106patients,65%of new compression fractures afterpercutaneous kyphoplasty were adjacent vertebral compression fractures.Inpatients who experienssion vertebral compression fractures2times,lowerbaseline bone miner density were demonstrated in this study.The genderand T2value of discs were not statistically different between Group A(1vertebral compression fracture) and B(vertebral compression fracture2times). Conclusion New compression fractures after percutaneouskyphoplasty occur repeatedly within a few years.New-onset adjacent-levelfractures are more predominate than nonadjacent level fractures. Lowerbaseline bone miner and postkyphoplasty disc space bone cement leakageare factors for multiple vertebral compression fractures. |
