Cervical open door laminoplasty is widely used in multilevel decompression, which is a motion-sparing decompression treatment option for multilevel cervical myelopathy. Implant distance migration in cervical laminoplasty has not been reported. A 61-year-old woman underwent cervical laminoplasty, three months postoperatively, she experienced left shoulder pain and left upper limb pain, and underwent cervical magnetic resonance imaging, which showed no abnormalities. She gradually developed dizziness, headache, unstable walking, incomplete urinary incontinence, and fluctuating neck lumps. The X-ray showed that the screws of the C7 lateral mass had disappeared and migrated to the sacral canal. The patient underwent cerebrospinal leakage repair and removal of the screws in the spinal canal. Displacement of fixators implanted into the spinal canal after cervical laminoplasty is a rare complication that can cause permanent neurological injury.
颈椎开门椎管成形术广泛应用于多节段减压，是多节段颈椎病的一种保留运动功能的减压治疗选择。颈椎板成形术中的植入物距离迁移尚未有报道。一位 61 岁女性行颈椎板成形术，术后 3 个月，她出现左肩部疼痛和左上肢疼痛，并接受颈椎磁共振成像检查，未见异常。她逐渐出现头晕、头痛、行走不稳、不完全性尿失禁和颈部肿块波动。X 线片显示 C7 侧块的螺钉已经消失并迁移到骶管。患者接受了脑脊液漏修复和椎管内螺钉取出术。颈椎板成形术后固定器植入椎管内移位是一种罕见的并发症，可导致永久性神经损伤。
