Abstract: It is very difficult to fix the comminuted radial head fracture of Mason type Ⅲ. Surgical methods include radial head resection, screw and plate fixation, and artificial radial head replacement. However, the surgical methods are controversial. In this article, a case of reconstruction of the radial head and obtaining a good function of the elbow joint with the self-made bone harvester was reported. This paper introduces the method of reconstructing the radial head with selfmade bone remover, and provides new ideas for the treatment of unstable comminuted radial small head fracture in the future.

Key words: radial head fracture, self-invented bone extractor, reconstruction, ilium
