This study compares outcomes of vertebroplasty(VP) and kyphoplasty(KP) in 125 consecutive female Asian patients above 65 years with L1 osteoporotic vertebral compression fractures 57 and 68 patients underwent VP and KP respectively from 2004 to 2008. Outcomes were measured prospectively at pre-operation, 1 month, 6 months and 2 years post-operation by blinded assessors. Radiographic outcome: Anterior, middle and posterior vertebral heights of the L1 vertebral body Functional outcome: Short-Form 36(SF-36) score, Visual Analogue Scale(VAS) score for back painIntroduction
Methods
The risk factors for new adjacent vertebral compression fracture (NAVCF) after Vertebroplasty (VP) or Kyphoplasty (KP) for osteoporotic vertebral compression fractures (VCFs) were investigated. The authors retrospectively analyzed the incidence of NAVCFs in 135 patients treated with VP or KP for osteoporotic VCFs. Study period was from 2004 to 2008 with minimum follow-up of 2 years. Possible risk factors were documented: age, gender, body mass index, bone mineral density (BMD), co-morbidities, location of treated vertebra, treatment modality and amount of bone cement injected. Anterior-posterior vertebral body height ratio, intra-discal cement leakage into the disc space and pattern of cement distribution of the initial VCF and adjacent vertebral bodies were assessed on lateral thoracolumbar radiographs by 2 independent assessors.Introduction
