Progressive kyphosis after vertebroplasty in osteoporotic vertebral compression fracture.

摘要: Study design A single-center retrospective study. Objective To identify the relevant incidence and risk factors of delayed vertebral collapse progressive kyphosis with spinal canal encroachment after percutaneous vertebroplasty (PVP) for compression fracture (VCF). Summary background data Delayed are complications PVP VCF. Methods Between December 2002 February 2011, 843 patients underwent VCFs at least 2 years minimum follow-up term in a tertiary referral center. All imaging measurements were obtained digitally, comparisons Cobb angle stenosis on fractured level 3 different time points pre- postvertebroplasty, before revision surgery. Results Thirteen (14 fractures) who had vertebra, male 10 female, median age 75 (range, 66-89 yr). One 2-level VCFs. treated surgery decompressive laminectomy neurological complications. Twelve additional instrument fixation. The involved vertebras concentrated thoracolumbar junction region (T11-L2). mean angles measured 23.67° PVP, 15.90° 30.92° ratio was 35.45% 49.48% surgery, respectively. occurrence rate about 1.5% (13/843). Conclusion Conservative treatment minimal invasive augmentation can be selected from stable Close is warrant to monitor late Level evidence N/A.
