Objective:Recently, the definition of occult osteoporotic vertebral fracture has been established, and its clinical significance has come to our interest. We report the effect of early percutaneous vertebroplasty in occult osteoporotic vertebral fracture.
Methods:From January 2006 to January 2008, we performed percutaneous vertebroplasty for 50 levels in 47 patients. 21 levels (21 patients) of them were classified into occult osteoporotic vertebral fracture group, 29 levels (26 patients) were categorized into control group (not occult osteoporotic vertebral fracture) by the Pham T..s criteria. We obtained VAS score and measured the compression ratio at first hospital day and 1 day, 1 month, 3 months after procedure.
Results:There are noticeable improvements in VAS score. The mean VAS score at admission was 6.44 in occult group and 6.15 in control group, which changed 2.23 in occult group and 2.68 in control group after procedure. The compression rate was 1.008, 1.018, 1.016 in occult group and 0.862, 0.891, 0.881 in control group at admission and 1 month, 3 months after procedure. The conservative effect for vertebral height was higher than control group (p=0.011).
Conclusions:Percutaneous vertebroplasty in occult osteoporotic compression fracture provided significant pain relief and conservative effect for vertebral height. It is probable that it can lower the rate of secondary adjacent vertebral compression fracture.
