摘要
背景:近年来仅报道椎体成形对轻中度椎体压缩性骨折治疗,但很少报道椎体成形治疗严重椎体压缩性骨折类型如椎体塌陷研究。目的:评估经皮椎体成形治疗椎体严重压缩性骨折的有效性和影像学特点。方法:25例患者经历单个水平椎体压缩性骨折经皮椎体成形治疗。分析压缩椎体位置、压缩形式、塌陷程度、椎体成形前后脊椎后凸角和邻近椎间盘高度。结果与结论:60%(16/25)的患者累及胸腰段。塌陷椎体高度为原椎体高度的14%-30%,平均塌陷高度为5.17 mm或原椎体的22%。椎体成形前病灶驼背角度为0-33°(平均16°),治疗后为12°。椎体成形前受累水平上邻近椎间盘高度为7.3 mm,邻近下一椎间盘高度为7.7 mm。椎体成形前目测类比评分显著高于椎体成形后,表明改善疼痛方面差异有显著性意义(P<0.015)。结果提示经皮椎体成形是治疗单个严重椎体压缩性骨折较为安全、有效的方法。
BACKGROUND：Recent reports only concern vertebroplasty for mild to moderate vertebral compression fractures, but seldom address vertebroplasty for severe vertebral compression fractures such as vertebral colapse. OBJECTIVE：To evaluate the efficacy and imaging features of percutaneous vertebroplasty for severe vertebral compression fractures. METHODS：A total of 25 patients underwent single-level vertebroplasty for vertebral compression fractures. Imaging features were then analyzed including location, pattern of compression, extent of colapse, pre- and post kyphotic angle and adjacent disc height before and after vertebroplasty. RESULTS AND CONCLUSION：60% （16/25） patients involved the thoracolumbar junction. The height of colapsed vertebral body was 14%-30% of original vertebral body. The average height of colapse was 5.17 mm or 22% of original vertebral body. Kyphotic angle before vertebroplasty ranged from 0-33° （averagely 16°） with an average correction of 12° after vertebroplasty. Average disc height before vertebroplasty was 7.3 mm above and 7.7 mm below. Visual analogue scale score was significantly higher preoperatively than that postoperatively, showing significant difference in pain improvement （P〈 0.015）. These data suggest that percutaneous vertebroplasty is safe and effective in the treatment of single level severe vertebral compression fractures.
