ObjectiveTo study the effect on pain of per-cutaneous cementoplasty for painful extraspinal bone metastasis.Method43 patients with extraspinal bone metastasis were included between April 2006 and October 2014 in this retrospective monocenter study. The primary endpoint was pain level measured on a 0–10 numeric rating scale at week 1 after cementoplasty as compared with pre-cementoplasty. Secondary endpoints were long-term pain level and impact on quality of life and disability.ResultsMean pain score was 4.2 (SD ±3.6) before cementoplasty and 1.09 (SD ±2.4) at week 1 (p = 0.005) (n = 31 patients). At 22 months after cementoplasty, quality of life and disability improved (according to the patient global assessment) for 47.6% and 52.2% of patients (n = 21patients). We did not find a predictor of good response. Cement leakage was the most common adverse event.ConclusionPercutaneous cementoplasty of extraspinal bone metastasis is a rapidly efficient treatment with few adverse events. Its efficacy persists over time, with a benefit for disability and quality of life. Although this technique is only palliative, it should be considered in this situation.
