title: Computed tomography-guided coblation and cementoplasty of a painful acetabular metastasis: an effective palliative treatment.
abstract: Percutaneous cementoplasty is an effective palliative treatment for acetabular metastases. Potential problems with this technique include inadequate filling and intra-articular cement leakage, leading to increased hip pain. We present a case of metastatic non-small cell lung cancer in which we illustrate how using radiofrequency coblation prior to cement injection creates a well-defined cavity allowing controlled cement injection limiting cement extrusion. To the best of our knowledge this is the first report in which coblation of an acetabular metastasis prior to cement filling has been performed.
