Percutaneous vertebroplasty is an effective tool for the relief of pain caused by osteoporotic spine fractures. Our purpose is to evaluate this technique and its effectiveness in restoring the height of such fractures.
Forty osteoporotic vertebral body fractures in 30 consecutive patients (24 female, six males; mean age, 70 years) were analyzed retrospectively, before and after percutaneous vertebroplasty, for changes in vertebral body height, kyphosis angle, and wedge angle. The ages of the fractures range from 1 to 5 months.
Percutaneous vertebroplasty improved the pretreatment height of compression fractures in these patients by a mean of 47.6% (P < .001), with only 15% showing no improvement. These figures compare favorably with published results for kyphoplasty (47% mean improvement in height in 70% of fractures; no improvement in 30% of fractures). In addition, we achieved a mean improvement in kyphosis angle of 6 degrees and an improvement in the wedge angle of 3.5 degrees (as compared with published results for kyphoplasty of 7.4 and 4.3 degrees , respectively; P < .001).
Percutaneous vertebroplasty should be viewed not only as a pain-relieving procedure, but also an effective method for improving vertebral body height, kyphosis angle, and wedge angle.
经皮椎体成形术是缓解骨质疏松性脊柱骨折所致疼痛的有效手段。我们的目的是评估该技术及其在恢复此类骨折椎体高度方面的有效性。
回顾性分析30例连续患者（24例女性，6例男性；平均年龄70岁）的40例骨质疏松性椎体骨折，观察经皮椎体成形术前、后椎体高度、后凸角和楔形变角的变化。骨折时间为1至5个月。
经皮椎体成形术使这些患者压缩骨折的术前椎体高度平均提高了47.6%（P <.001），仅有15%无改善。这些数据优于已发表的椎体后凸成形术结果（70%的骨折椎体高度平均改善47%；30%的骨折无改善）。此外，我们使后凸角平均改善了6度，楔形变角改善了3.5度（与已发表的椎体后凸成形术结果分别为7.4度和4.3度相比；P <.001）。
经皮椎体成形术不仅应被视为一种缓解疼痛的方法，而且是改善椎体高度、后凸角和楔形变角的有效方法。
