Percutaneous cementoplasty of lytic metastasis in left acetabulum.

Minimally invasive procedures such as percutaneous cementoplasty can provide immediate pain relief and can restore mechanical stability for patients with bone metastases who are not candidates for surgery or who show resistance to radiotherapy or analgesic treatment. Here, we examine a case of percutaneous cementoplasty to treat a lytic lesion of the acetabulum from breast cancer. Good filling was observed, and no complications occurred. A research assistant recorded the patient's scores on the Karnofsky Performance Scale, Townsend Functional Assessment Scale, and Brief Pain Inventory before surgery and at days 1, 2, and 4 and weeks 1, 2, and 4 post-procedure. Improvement in pain and walking ability was demonstrated within the first 48 hours of treatment, and that improvement remained constant throughout follow-up. These findings echo the literature, in that percutaneous cementoplasty provides immediate and long-term pain relief with few complications. We recommend that percutaneous cementoplasty be used as an additional tool for palliative treatment of patients with bone metastases.
