Abstract
This report presents the long-term effect of plate osteosynthesis to repair a right forearm fracture in an 11-year old patient, who 6 years later requested removal of her plates because of the pain she was experiencing in the area. The 17 year-old female had developed simple bone cysts around the implanted plates for her radius and ulnar fracture. Circulatory disturbances might have a role in the development of the simple bone cysts in this case.
