BACKGROUND Bone cement dislodgement (BCD) is a recognized complication of percutaneous vertebroplasty (PVP) that may be more common after percutaneous kyphoplasty (PKP). This report describes a 71-year-old woman with cement dislodgement following PKP of an osteoporotic T12 vertebral fracture successfully treated with repeat vertebroplasty(VP) through the right pedicle. CASE REPORT A 71-year-old woman underwent PKP surgery for T12 vertebral fracture caused by a fall. The pain disappeared after surgery, but 2 weeks later, she felt obvious pain again without any cause. Computed tomography (CT) showed BCD in T12 vertebra. Repeat PVP surgery was performed through the right pedicle, then the pain disappeared again. Six months later, the VAS score was 1 and the ODI score was 6.4%. CONCLUSIONS BCD is a complication of PKP that can occur without trauma. CT can definitively establish the diagnosis. Repeat VP is an effective treatment option for managing this condition, even when only the unilateral pedicle is accessible.
骨水泥移位（BCD）是经皮椎体成形术（PVP）公认的一种并发症，在经皮椎体后凸成形术（PKP）后可能更为常见。本报告描述了一名71岁女性，在经皮穿刺对骨质疏松性T12椎体骨折行PKP术后出现骨水泥移位，通过右侧椎弓根再次行椎体成形术（VP）成功治疗。病例报告：一名71岁女性因跌倒导致T12椎体骨折接受PKP手术。术后疼痛消失，但2周后，她无明显诱因再次感到明显疼痛。计算机断层扫描（CT）显示T12椎体存在骨水泥移位。通过右侧椎弓根再次进行PVP手术，之后疼痛再次消失。6个月后，视觉模拟评分（VAS）为1分，Oswestry功能障碍指数（ODI）为6.4%。结论：骨水泥移位是PKP的一种并发症，可在无创伤情况下发生。CT能够明确诊断。即使仅可通过单侧椎弓根进行操作，再次行VP也是治疗这种情况的有效选择。
