A new injury patt of comminuted fractures of ipsilateral radial head and distal radius of forearm in an adult was described.To the best of our knowledge, this wpe of injury patt had not been previously reported in the English literature.The possible mechanisms of injury were that the rebound forces were volar to the distal radius as the fracture was dorsally angulated, with a continuation of the radial head fracture due to the longitudinal impaction of the radius against the capitellum.Open reduction and intal fixation can obtain excellent results within 7-12 days after injury.We hope that our experience will increase the awareness of the occurrence of a double injury of the forearm.
