An isolated posterior dislocation of the radial head is a rare injury. We present a case report on an 11-year-old boy with a traumatic posterior radial head dislocation without fracture or bending of the ulna. The diagnosis can be difficult and should be supported with good radiographic images, since clinically the injury can be missed or misdiagnosed.
