Sacral fractures are rare but severe injuries. They are often associated with neurological impairment and pelvic instability. We present a case of a 28-year-old woman who sustained an H-type fracture of the sacrum with complete cauda equina syndrome treated with cauda equina decompression and pelvic percutaneous stabilization with an iliosacral screw. Two years after she underwent screw removal, but complained of back and nape pain after the operation. A lumbosacral MRI showed the presence of a lytic lesion involving the S1 and S2 bodies that was judged to be a pseudomeningocele leaning against the sacral screw hole and cerebrospinal fluid fistulas through this. To our knowledge, this is the first case of such a complication after sacral screw removal to be reported.
骶骨骨折较为罕见，但较为严重。常伴有神经功能障碍和骨盆不稳定。我们报告了一例 28 岁女性患者，她发生 H 型骶骨骨折，伴有完全马尾综合征，接受马尾神经减压和骨盆经皮固定术（髂骨骶骨螺钉）治疗。在螺钉取出两年后，她主诉术后出现腰背和颈项疼痛。腰骶部 MRI 显示 S1 和 S2 体存在溶骨性病变，判断为假性脑脊膜膨出，靠在骶骨螺钉孔上，并通过该孔出现脑脊液漏。据我们所知，这是首例此类并发症的病例报告。
