Radial head dislocation with ipsilateral radial shaft fracture is one of the reportable trauma case with very low incidence. Only 4 cases of this type injury have been reported worldwide. In 3 cases of them, good results were achieved after early closed reduction of the radial head, followed by internal fixation of the radial shaft. In the a u t h o r s'case, the patient received the same method of treatment mentioned at the previous successful 3 cases. But after that, he suffered from repeated dislocations and finally nonunion of the fracture. At last, the authors could obtain bony union and stable elbow joint after radial head resection and osteosynthesis using autologous cancellous bone graft, but resulted in limitation of motion. We report the case and the experience of treatment.
