Bone filling mesh container for osteoporotic vertebral fractures with posterior vertebral wall breakage：it is effective for prevention of bone cement leakage / 中国组织工程研究

ABSTRACT

BACKGROUND:Percutaneous kyphoplasty for osteoporotic vertebral fractures with posterior vertebral wal breakage can relieve pain rapidly, but there is a risk of leakage of bone cement. OBJECTIVE: To observe the effect of bone filing mesh container in percutaneous kyphoplasty for osteoporotic vertebral fractures with posterior vertebral wal breakage. METHODS: Forty senile patients with osteoporotic vertebral compression fractures were enroled, whose CT and MRI showed different degrees of posterior vertebral wal breakage, including 19 males (21 vertebral bodies) and 21 females (28 vertebral bodies), aged 50-87 years. These 40 patients were subjected to percutaneous kyphoplasty, and bone filing mesh container was used to deliver bone cement. Then, changes in visual analogue scale score, vertebral height and leakage of bone cement were observed in patients before and after treatment. RESULTS AND CONCLUSION:The surgery was successful in al the 40 patients, and no pulmonary embolism, cement leakage, and spinal cord and nerve root injuries appeared. Al the patients were folowed for 10-12 months. The visual analogue scale scores and vertebral height were improved significantly at both 1 week and 3 months after treatment compared with those before treatment, but there was no difference in the visual analogue scale scores and vertebral height at 1 week and 3 months after treatment. These findings indicate that percutaneous kyphoplasty with bone filing mesh container is effective to prevent bone cement leakage.
