Objective To investigate the treatment of Mason type-Ⅲ radial head fracture with open reduction and internal fixation. Methods Open reduction and internal fixation were performed to put the radial head in the appropriate location, and then fix the radial head to the ulna temporary with kirschner wire to keep humeroradial contact and the length of radius. The bone defects were treated with a tricortical iliac-crest bone grafts and small type-T plate fixation. Results After 2 to 4 years follow-up, the motion function of elbow joint were excellent and good in six of all seven patients. One patient developed nonunion due to avascular reason. Conclusions This procedure provide an alternative treatment for Mason type-Ⅲ radial head fracture. It can decrease the rate of resection of radial head and prostheses replacement.
