Purpose: We report the case of a 43-year-old man with metastatic breast carcinoma to the proximal right femur resulting in severe painful pathological fracture. The patient experienced severe pain despite large doses of analgesia, resulting in impaired functionality and quality of life. The patient had significant comorbidities, making him a high surgical risk. Materials and Methods: The patient was treated with cryoablation and osteoplasty, followed by a novel technique consisting of osteoplasty reinforced with bone marrow Kirschner wires (K-wires) which will be described in details in this report. Results: The patient reported significant pain relief after the procedure, and gained right lower extremity functionality, as compared to total immobility before the procedure. Conclusion: Our technique offers an alternative feasible treatment for patients at high surgical risk with pathological fractures in weight-bearing bones, in which osteoplasty alone has a high risk of cement leakage, inadequate fracture reduction, and early refracture. To our knowledge, our technique has not been previously described. © 2012 Springer Science+Business Media, LLC and the Cardiovascular and Interventional Radiological Society of Europe (CIRSE).
