Abstract

PURPOSE:

The aim of this study was to compare the effectiveness of percutaneous vertebroplasty and kyphoplasty to treat pain from non-neoplastic vertebral fractures and improve functional outcomes.

MATERIALS AND METHODS:

We compared 30 patients treated by vertebroplasty for non-neoplastic vertebral fractures with 30 patients treated by kyphoplasty for the same condition. Pain was measured with a visual analogue scale (VAS) and functional outcome with the Oswestry disability index (ODI). Baseline data were compared with measurements on the day after the procedure (for pain alone) and at 1 month, 6 months, and 1 year.

RESULTS:

The VAS pain score was reduced by 4-5 points on the day after either type of treatment, a statistically significant improvement. The global ODI was significantly improved (by 13-18 points) at 1 month after either procedure. These improvements persisted at 6 months and 1 year. No significant differences in functional outcome were observed between the techniques.

CONCLUSION:

Vertebroplasty and kyphoplasty obtain similar improvements in pain and functional outcomes in these patients. The choice of technique must therefore depend on other factors. An initial improvement with either technique is a good predictor of long-term improvement.
