We assessed radiographic and functional outcome in 13 patients with a minimum of 5 years follow-up from a prospectively monitored series of 17 patients who underwent percutaneous vertebroplasty (PPV). A visual analogue scale (VAS) and the short McGill questionnaire (MPQ) were used to assess average symptoms. The VAS showed significant improvement after treatment: the initial score was 9.07+/-0.6 (mean+/-SD), falling to 2.07 (1.14) on the third day, 1.07 (1.07) by the third month and 2.15 (2.6) at 5 years. Pain reduction was statistically significant ( P<0.001). The MPQ showed a significant improvement after treatment ( P<0.001), but had worsened by the last follow-up. All patients were "very" or "somewhat satisfied" with the procedure. We saw no further collapse of the vertebrae injected or migration or changes in the shape of the cement. A new fracture was seen in three patients, affecting four vertebrae, only two of which were adjacent to the treated level. On CT following the procedure, there was cement in the epidural veins adjacent to the vertebra in 48% of cases, but only patient developed a transitory neuritis.
我们对13例患者进行了影像学和功能评估，这些患者来自一个前瞻性监测的17例接受经皮椎体成形术（PPV）患者系列，随访时间至少5年。采用视觉模拟量表（VAS）和简短麦吉尔问卷（MPQ）评估平均症状。治疗后VAS显示出显著改善：初始评分为9.07±0.6（均值±标准差），第三天降至2.07（1.14），第三个月为1.07（1.07），5年时为2.15（2.6）。疼痛减轻具有统计学意义（P<0.001）。MPQ治疗后显示出显著改善（P<0.001），但在最后一次随访时有所恶化。所有患者对该手术“非常”或“有些”满意。我们未观察到注入椎体的进一步塌陷、骨水泥移位或骨水泥形状改变。3例患者出现新骨折，累及4个椎体，其中只有2个与治疗节段相邻。术后CT检查发现，48%的病例中椎体旁硬膜外静脉有骨水泥，但只有1例患者发生短暂性神经炎。
