ABSTRACT
Percutaneous acetabular osteoplasty is a radiological interventional procedure consisting
of the injection of methylmethacrylate into osteolytic metastases and myeloma of the
acetabular roof. This injection allows rapid pain relief and walking improvement in
most cases. However, this is a palliative procedure and only to patients who cannot
undergo surgery, and must be offered in association with radiotherapy. Associated
osteolysis of the acetabular fossa, favoring the risk of acetabular protrusion, may
limit the benefits of the technique. Ethanol injection may represent an alternative
treatment in cases of extensive bone destruction or of osteolysis not located in the
weight-bearing part of the acetabulum.
