Objective: To determine the incidence of additional vertebral compression fractures (VCF) and the degree of pain reduction after percutaneous vertebroplasty (PV) over 1year follow up. Method: This retrospective study compared patients treated by PV and conservative treatments for VCF (VP group) with patients treated by conservative treatments only for the same condition (Non-VP group). Conservative treatments included medication (oral bisphosphonate and calcium citrate) and teaching exercise program. All patients were followed up at least 1 year later from initial treatment. Pain reduction was measured using visual analogue scale (VAS). Additional VCF was evaluated by follow up radiograph. Results: 44 patients (71±9 years) were in VP group and 60 patients (71.5±6.9 years) were in Non-VP group. The mean duration after VCF was 31.4± 12.5 months in VP group and 27.4±15.6 months in Non-VP group. There was no significant difference in the sex, age and the duration after treatment between two groups. VP group, 15 (34.1%) patients suffered newly developed VCF. In Non-VP group, 20 (33.3%) patients suffered newly developed VCF. There was no significant difference in the incidence of newly developed VCF between the two groups. Levels of new fractures between two groups did not show significant difference. VAS reduction was more prominent within 1 week after PV (p＜0.05). Conclusion: Compared with Non-VP group, PV provided immediate pain reduction and did not increase the incidence of additional VCF.
