OBJECTIVE: To evaluate the effectiveness of percutaneous vertebroplasty for metastatic tumor of thoracic lumbar vertebrae by bone cement perfusion at different times and temperature gradient. METHODS: A total of 24 cases (38 vertebrae) of metastatic tumor receiving percutaneous vertebroplasty and bone cement perfusion at different times and temperature gradient were reviewed retrospectively. All patients were classified into group A (11 vertebrae in 9 cases) featured with apparent vertebral compression (? 1/4) and group B (27 vertebrae in 15 cases) of no obvious compression (< 1/4). The percutaneous vertebroplasty was conducted with C-arm fluoroscopy positioning. Bone cement was injected by perfusion at different times and temperature gradient method. Visual Analogue Scales and Owestry Disability Index were recorded to assess pain alleviation and functional restoration before and after bone cement injection at different times and temperature gradient. The height of treated vertebrae was also analyzed. Follow-up was performed for 12 to 56 months. RESULTS AND CONCLUSION: All 24 patients successfully underwent percutaneous vertebroplasty and bone cement perfusion at different times and temperature gradient. Bone cement (4?1) mL was averagely injected into each thoracic vertebra. Bone cement (5?1) mL was injected into each lumbar vertebra. Postoperative recheck radiographs revealed good bone cement distribution, no nerve root injury or spinal compression occurred. Vertebral height was significantly higher posttreatment compared with pretreatment in both groups (P < 0.05). Visual Analogue Scales and Owestry Disability Index scores were significantly lower at 1 day, 1 month after treatment and during final follow-up compared with preoperation in all patients (P < 0.05). No significant difference in Visual Analogue Scales and Owestry Disability Index scores was detected between two groups at the same time point. Results suggested that percutaneous vertebroplasty and bone cement perfusion at different times and temperature gradient for metastatic tumor of thoracic lumbar vertebrae could reduce the occurrence of bone cement leakage, and could ease the pain quickly for apparent and non-apparent compressed tumor metastatic vertebrae. It is an effective method to treat metastatic tumor of vertebrae. 中国组织工程研究杂志出版内容重点:人工关节;骨植入物;脊柱;骨折;内固定;数字化骨 科;组织工程 全文链接: Key words: spine; bone neoplasms; vertebroplasty; 中图分类号: R318 通讯作者: 杨惠林，主任医师，教授，博士生导师，苏州大学附属第一医院骨科，江苏省苏州 市 215006 作者简介: 张凡，男，1989年生，江苏省兴华市人，汉族，苏州大学在读硕士，主要从事脊 柱、关节疾病的基础与临床研究。 引用本文: 张 凡,杨惠林,管华清. 经皮椎体后凸成形分次和温度梯度灌注骨水泥治疗胸腰椎转移性肿瘤[J]. 中国 组织工程研究, 2014, 18(26): 4206-4211.
