Abstract：
OBJECTIVE: We aimed to preliminarily explore the efficacy and safety of unilateral biportal endoscopy (UBE) for the treatment of epidural cement leaks. We report a patient who underwent epidural cement leakage removal and achieved endoscopic spinal decompression.
METHODS: A 67-year-old female patient underwent biportal endoscopic paraspinal decompression following percutaneous vertebroplasty for an osteoporotic fracture that resulted in neurologic impairment due to epidural cement leakage. A transforaminal biportal endoscopic surgery was performed to remove the leaked cement, and the left L1 and bilateral L2 nerves were decompressed.
RESULTS: The patient\'s postoperative clinical course was uneventful.
CONCLUSIONS: A paraspinal approach that avoids a posterior approach reduces the need to remove stabilizing facet bone, is truly minimally invasive and does not involve an instrumented fusion, maybe a helpful addition in the minimally invasive spine surgeon\'s armamentarium.

摘要：
目的：我们旨在初步探讨单侧双入口内镜（UBE）治疗硬膜外骨水泥渗漏的有效性和安全性。我们报告了一名接受硬膜外水泥渗漏清除并实现内窥镜脊柱减压的患者。
方法：一名67岁的女性患者在经皮椎体成形术治疗骨质疏松性骨折后接受了双门静脉内镜下椎旁减压术，导致由于硬膜外骨水泥渗漏引起的神经功能缺损。进行了经椎间孔双门内窥镜手术，以去除泄漏的水泥，左L1和双侧L2神经减压。
结果：患者的术后临床过程顺利。
结论：避免后路的椎旁入路减少了移除稳定小关节骨的需要，是真正的微创，不涉及仪器融合，在微创脊柱外科医生的医疗设备中可能是一个有用的补充。
