Balloon kyphoplasty has been shown to be safe in treatment of vertebral compression fractures refractory to conservative management. However, few reports have focused on lateral wedging of cemented vertebra after kyphoplasty. A 72-year-old woman with a T12 osteoporotic compression fracture underwent kyphoplasty using polymethylmethacrylate (PMMA) via a bipedicular approach. The patient felt pain free, whereas she did not receive anti-osteoporosis treatment after the surgery. The abnormal spatial distribution of PMMA cement within the T12 vertebral body and cement leakage right lateral to the vertebral body was observed in postoperative radiographs. Twelve months later, lateral wedging of the cemented vertebra was detected in plain radiographs. In the kyphoplasty procedure, symmetric cement filling should be achieved to avoid lateral wedging of the cemented vertebra. Postoperative anti-osteoporotic medication treatment is also very important.
经皮球囊椎体后凸成形术已被证明在治疗保守治疗无效的椎体压缩骨折方面是安全的。然而，很少有报告关注椎体后凸成形术后骨水泥强化椎体的侧方楔形变。一名72岁患有T12骨质疏松性压缩骨折的女性患者通过双侧椎弓根入路使用聚甲基丙烯酸甲酯（PMMA）进行了椎体后凸成形术。患者术后无痛，然而术后未接受抗骨质疏松治疗。术后X线片观察到T12椎体内PMMA骨水泥异常的空间分布以及椎体右侧的骨水泥渗漏。12个月后，在X线平片上检测到骨水泥强化椎体的侧方楔形变。在椎体后凸成形术中，应实现骨水泥的对称填充以避免骨水泥强化椎体的侧方楔形变。术后抗骨质疏松药物治疗也非常重要。
