Although often a benign complication of total hip arthroplasty, cement extrusion can cause nerve, vessel, and organ compression. We report the case of a 70-year-old male patient in whom an extruded cement mass migrated anteriorly and compressed the femoral nerve and impinged on the femoral artery producing acute, severe groin pain with neuralgia 9 years postoperatively. Paresthesia of the anterior and medial thigh was found on examination. Radiographic, ultrasound, and computed tomographic studies confirmed a 6 × 1.5-cm mass of bone cement in the right groin compressing the femoral nerve that was removed successfully at surgery. Six months postoperatively, the patient's pain had resolved, but hyperesthesia of the medial thigh remained.
虽然骨水泥挤出通常是全髋关节置换术的良性并发症，但它可导致神经、血管和器官受压。我们报告了 1 例 70 岁男性患者，其挤出的骨水泥块向前迁移，压迫股神经并撞击股动脉，导致术后 9 年出现急性剧烈腹股沟疼痛伴神经痛。检查发现大腿前内侧感觉异常。影像学、超声和 CT 研究证实右侧腹股沟有 6×1.5cm 的骨水泥肿块压迫股神经，手术成功切除。术后 6 个月，患者疼痛缓解，但大腿内侧仍感觉过敏。
