We reported an extremely rare case of Monteggia's fracture with fracture of the medial epicondylar apophysis. A five-year-old girl was admitted after a fall. Plain radiographs of the elbow and forearm revealed acute plastic bowing of the ulna, anterior dislocation of the radial head, and fracture of the medial epicondylar apophysis. Six days after injury, closed reduction and osteosynthesis were performed. During the follow-up at eight months, the patient achieved bony union and well range of motion of the elbow and forearm.
