Abstract

Objective:To assess the effects of percutaneous vertebroplasty(PVP) for relieving back pain in patients with vertebral metastases.Methods:From January 2005 to April 2009,51 patients underwent PVP on 101 vertebrae.Pain was evaluated with the pain intensity numeric rating scale(PI-NRS)(0 = no pain;10 = the worst pain) before the procedure and at the end of follow-up.Analgesic drugs were recorded meanwhile.A reduction of at least two points of the PI-NRS score was considered clinically significant. Results:No severe complications were observed after operations.During follow-up for 1-9 months(mean 3.6 months),a clinically significant pain reduction was observed in 48 of 51 patients (94%),and 38 of 51 patients(75%) did not need analgesic drugs.Conclusion:Vertebral metastases-induced back pain can be safely and effectively controlled by PVP.
