title: Femoral nerve compression after migration of bone cement to the groin after hip arthroplasty.
abstract: 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.
