[Percutaneous vertebroplasty in symptomatic osteoporotic vertebral compression fractures: review of 50 patients].

PURPOSE
Evaluation of percutaneous vertebroplasty (PVP) in symptomatic osteoporotic vertebral compression fractures after failure of conservative management.


MATERIALS AND METHODS
Retrospective study of cases performed between 2002 and 2005 in a single institution. Outcome was measured using Huskisson's visual analogue scale.


RESULTS
A total of 77 vertebrae in 50 patients were treated. Mean follow-up was 12.9 months (1-36 months). Significant symptomatic improvement (p<0.001) was noted with pre PVP pain score of 7.4 (+/-0.99), 24 hour and 1 month post PVP score of 2.31 (+/-2.65), 6 month post PVP score of 2.4 (+/-2.7) and 18 month post PVP score of 2.91 (+/-2.91). Seven patients presented with a new symptomatic vertebral compression fracture, with 5 cases adjacent to the treated level.


CONCLUSION
Percutaneous vertebroplasty is reliable and effective in the treatment of symptomatic osteoporotic vertebral compression fractures.
