Treatment of Metastatic Carcinoma to the Hip with CT-guided Percutaneous Acetabuloplasty: Report of Four Cases

Percutaneous acetabuloplasty (PA) is a promising treatment for painful metastatic lesions of the acetabulum. Four patients were treated with injection of the bone cement polymethylmethacrylate directly into the lesion. After the procedure, all four patients had improvement or relief of their pain and were able to resume weight-bearing activities. The procedure was well tolerated by each patient without morbidity. PA appears to be a reasonable palliative procedure for painful and fragile hips associated with metastatic bone disease.
