目的：比较评估改良单侧经皮椎体成形术治疗椎体压缩性骨折的临床结局方法：回顾性分析了2005年12月至2008年12月在我院连续治疗的70例患者的临床结局和骨水泥挤出的发生率。35例患者随机分为改良经皮椎体成形术组（A组）和传统经皮椎体成形术组（B组）。在术后第一天和1年后使用视觉模拟量表（VAS）评估椎体成形术前后疼痛的严重程度。结果：70例患者均获得成功。骨水泥挤出发生率A组为14.29%（5/35例），B组为37.12%（13/35例），差异有统计学意义（P < 0.05）。无严重并发症。50例患者疼痛完全缓解，另外20例（20/70例患者）疼痛明显缓解。A组和B组之间无统计学显著差异。结论：改良经皮椎体成形术提高了骨水泥注入椎体中心的准确性，增加了手术的安全性，而不增加成本。与传统的经皮椎体成形术相比，它是治疗椎体压缩性骨折患者的一种更安全、更容易实施的技术。
OBJECTIVE: To comparatively assess the clinical outcome of modified unilateral percutaneous vertebroplasty for the treatment of osteoporotic vertebral compression fractures.METHODS: The clinical outcome and incidence of cement extrusion in a consecutive group of 70 patients at our institution between December 2005 and December 2008 was retrospectively reviewed. Thirty-five patients were randomly distributed to modified percutaneous vertebroplasty (Group A) and 35 to traditional percutaneous vertebroplasty (Group B). A visual analog scale (VAS) was used on the first post-operative day and 1 year later to assess the severity of pain before and after vertebroplasty. The incidence of cement extrusion on CT scan was also compared between the two groups.RESULTS: The treatment was successful in all seventy patients. The incidence of cement extrusion was 14.29% (5/35 patients) in group A, and 37.12% (13/35 patients) in group B, this difference being statistically significant (P < 0.05). No patients had serious complications. Complete pain relief was achieved in 50 patients, and significant relief in the other 20 (20/70 patients). There was no statistically significant difference between Groups A and B.CONCLUSION: Modified percutaneous vertebroplasty enhances the accuracy of cement injection into the center of the vertebral body, increasing the safety of the procedure with no increase in cost. It is a safer and more easily performed technique for treating patients with osteoporotic vertebral compression fractures than traditional percutaneous vertebroplasty.
