CASE: We report a novel case of the successful repair of a pathological fracture of a 14-year-old boy's proximal femur using open reduction and internal fixation with an adult 3.5-mm proximal humerus locking plate. CONCLUSION: Successful repair of a pediatric pathologic femur fracture due to an aneurysmal bone cyst may be achieved using an adult proximal humerus locking plate in select patients.
