The aim of this study is to assess the interest of cementoplasty in the management of bone metastases, based on a retrospective study involving 42 cementoplasty procedures. The median age of the patients is 59 years, with 24 women (57%) and 18 men, all of them presenting with an advanced disease. The cementoplasty was situated in long bones (ten patients), dorsal or lumbar vertebrae (13) and flat bones (20). The principal indication was pain, sometimes with consolidation. The intensity of pain decreases between the day before and the month following the treatment (P = 0.04) among the 25 patients who had pain assessment before and after the procedure. We note 57% good results (24 patients), 9.5% failures (4 patients), and 31% with partial results (13 patients), that is, a total of 88% with "partial or full" alleviation. 16 patients out of 22 (73%) who were no longer able to walk (because of the pain or risk of fracture) were able to resume walking. We observed in this series 40.5% of complications, all of them benign. Cementoplasty improves the quality of life of patients with bone metastases, by decreasing the pain in 88% of cases and allowing the resumption of walking in almost three-quarters of the patients who had lost the ability to walk.
