Unusual presentation of a profunda femoris pseudoaneurysm following osteosynthesis of proximal femur fracture

Profunda femoris artery injury following osteosynthesis of the proximal femur fracture is a rare complication and is usually caused by iatrogenic trauma or rarely due to bony spikes. Presentation can be delayed because of nonspecific features such as pain, swelling, anemia, fever, and hematoma. We report a case of posttraumatic profunda femoris aneurysm which presented more than a year after surgery with near-complete resorption of proximal femur and failure of implant requiring evacuation of huge layered thrombus, ligation of profunda femoris, and reconstruction of proximal femur with tumor megaprosthesis. Literature has not described a similar case.
