We wanted to investigate the leading cause of failed vertebroplasty or kyphoplasty.
Twelve patients (10 females and 2 males) who underwent revision surgery after vertebroplasty or kyphoplasty were included. In 4 cases, vertebroplasty was done for two or more levels. Six cases with kyphoplasty were included. Through the retrospective review of the radiographic studies and medical record, we analyzed the etiology of the revision surgery.
Uncontrolled back pain was the main clinical presentation. In 4 cases, neurological symptoms were noted, including one case with conus medullaris syndrome. The average time to the revision surgery after vertebroplasty or kyphoplasty was 15 months. Infection (4 cases) and progressive kyphosis with collapse (8 cases) were the causes for the revision. A solid pattern of inserted bone cement and bone resorption around the cement were noted in the all cases with progressive collapse and kyphosis.
Infection, misdiagnosis and progressive kyphosis were causes of the revision surgery after vertebroplasty and kyphoplasty. A solid pattern of accumulation of bone cement and peri-cement bone resorption might be related with the progressive collapse.
我们想要调查导致经皮椎体成形术或后凸成形术失败的主要原因。
纳入了 12 名（10 名女性和 2 名男性）接受经皮椎体成形术或后凸成形术翻修手术的患者。在 4 例病例中，进行了两个或更多节段的椎体成形术。纳入了 6 例后凸成形术病例。通过对影像学研究和病历的回顾性分析，我们分析了翻修手术的病因。
无法控制的背痛是主要的临床表现。在 4 例病例中，出现了神经症状，包括 1 例圆锥综合征。经皮椎体成形术或后凸成形术后翻修手术的平均时间为 15 个月。感染（4 例）和进行性后凸伴塌陷（8 例）是翻修的原因。在所有进行性塌陷和后凸的病例中，均可见插入骨水泥的实性模式和骨水泥周围的骨吸收。
感染、误诊和进行性后凸是经皮椎体成形术和后凸成形术后翻修手术的原因。骨水泥的积累和骨水泥周围骨吸收的实性模式可能与进行性塌陷有关。
