ABSTRACT

Sciatic neuropathy after total hip arthroplasty can result from several causes. We present a case in which a large cystic mass developed around a failed total hip arthroplasty. The lesion extended through the greater sciatic notch and into the pelvis producing sciatic nerve compression. The diagnosis was delayed, and the patient underwent a laminectomy without relief of symptoms before an abdominopelvic computed tomography (CT) scan revealed the mass. After revision of the components and excision of the accessible portion of the lesion, the symptoms improved. Resolution of the intrapelvic portion of the mass was demonstrated on follow-up CT scan, suggesting that retroperitoneal resection of this type of lesion may not be required at the time of revision of the components.
