Tumoral Dissemination Along the Screw Trajectory in Percutaneous Osteosynthesis and Cementoplasty: A Non-described Complication.

Percutaneous osteosynthesis and cementoplasty (POC), a minimally invasive technique, is used for pain palliation and prevention of pathological fractures in cancer patients that are noncandidates for surgical stabilization. POC is a relatively new technique, and very few complications have been described thus far. In this case study, we report on a tumorous dissemination along the screw trajectory after POC was used for the prevention of an impending pathological fracture on a trochanteric metastasis.
