An intravertebral vacuum cleft (IVC) is not an uncommon finding; it is more likely to occur in patients with osteoporotic vertebral compression fractures (OVCF). There are scarce data on the treatment of these patients with percutaneous balloon kyphoplasty (PKP). Between August 2005 and March 2010, 35 single vertebral fracture patients with an IVC sign were treated by PKP. Visual Analogue Score (VAS), Oswestry Disability Index (ODI), Kyphotic Angulation (KA), and Compression Ratio (CR) improved significantly postoperatively (p < 0.05). These values were maintained at the one year follow-up. Balloon kyphoplasty leads less often to leakage (here in only 14.3% of the patients) than vertebroplasty (in 75% according to the literature). On the other hand, balloon kyphoplasty seems to predispose to intradiscal leakage: here in 3 out of 5 cases. This may cause a compression fracture of the adjacent vertebra.
椎体内真空裂隙（IVC）并不少见；它更易发生于骨质疏松性椎体压缩骨折（OVCF）患者。关于经皮球囊后凸成形术（PKP）治疗这类患者的数据较少。2005年8月至2010年3月期间，35例有IVC征象的单节段椎体骨折患者接受了PKP治疗。术后视觉模拟评分（VAS）、Oswestry功能障碍指数（ODI）、后凸角（KA）和压缩率（CR）均显著改善（p<0.05）。这些值在一年随访时得以维持。与椎体成形术相比（根据文献报道为75%），球囊后凸成形术导致渗漏的情况较少（此处仅14.3%的患者出现渗漏）。另一方面，球囊后凸成形术似乎易引发椎间盘内渗漏：此处5例中有3例出现这种情况。这可能导致相邻椎体的压缩骨折。
