Abstract:

BACKGROUND: Percutaneous kyphoplasty with polymethylmethacrylate bone cement in the treatment of osteoporotic vertebra compression fractures is effective and rapid in pain relief.
OBJECTIVE: To evaluate the effectiveness of unipedicular percutaneous kyphoplasty with polymethylmethacrylate bone cement in the treatment of OVCFs.
METHODS: Twenty-two cases of fresh osteoporotic vertebra compression fractures were performed unipedicular percutaneous kyphoplasty with polymethylmethacrylate bone cement. Their clinical data were analyzed retrospectively.
RESULTS AND CONCLUSION: The mean follow-up time for the 22 cases was 2.5 years. Of all the cases, the leakage percentage was 4.5% and new vertebra fractures incidence was 9.1%. At 2 years postoperatively, Visual Analogue Scale scores were significantly improved than those preoperatively (P < 0.001); in terms of the location of bone cement, five cases were on the left side, and nine cases were in the middle as well as eight cases were on the right side. There was no correlation between pain relief and the location of bone cement (P=0.192). The anterior vertebral and middle margin height was significantly recovered postoperatively (P < 0.05). The amount of bone cement was 1-5 mL. There was no correlation between the insertion amount of bone cement and Visual Analogue Scale scores during the 2-year follow-up. These findings suggest that unipedicular percutaneous kyphoplasty is safe and effective in pain relief, however, the insertion site and the amount of bone cement has no influence on pain relief.
