Evaluation of safety and effectiveness of radiofrequency-targeted vertebral, augmentation (RF-TVA) in comparison to balloon kyphoplasty (BK) for the treatment of, acute painful vertebral compression fractures (VCF) on the basis of matched pairs.

METHODS:

A total of 192 patients (116 females; 51 – 90 y) with VCF (n=303) at one to three, levels were treated with RF-TVA or BK. Functionality (ODI), pain (VAS), vertebral, height (anterior, middle) and kyphotic angle were evaluated over a two year period, (postoperatively, 3-4 d, 3, 6, 12 and 24 mo). Additionally, operating time and, occurrence of cement leakage were recorded.

RESULTS:

Pain and functionality were significantly improved after both treatments. In both groups, there was an increase in vertebral height and a decrease in kyphotic angle, which, remained relatively consistent during 24 months. The incidence of cement leakage was, 9.4% (n=9) in the RF-TVA group and 24.0% (n=25) in the BK group. The mean, operating time with radiofrequency kyphoplasty was 25.9±9.9 minutes and with balloon, kyphoplasty 48.0±18.4 minutes.

CONCLUSION:

RF-TVA is a safe and effective procedure for the treatment of vertebral compression, fractures when compared to BK. Improvement in pain and functional scores following, RF-TVA are durable through 24 months post-procedure and remained better than, those following BK at long term follow up. Operating time for RF-TVA is shorter and the, risk of cement leakage is lower. Both procedures provided similar results in vertebral, height restoration and reduction in kyphotic angle.
