Abstract:
A fracture of the shaft of the humerus in young adults is known to occur as a result of high energy injuries such as traffic accidents and falls from a height. In baseball, which is one of the popular sports in the world, the incidence of a fracture of the shaft of the humerus during pitch motion is increasing even in non-professional players. Over the course of a year, we analyzed four cases of humeral shaft fractures that occurred during pitch motion through the pitch count, type of pitch, duration of playing, and prodromal pain. It was found that these fractures can easily occur through the torsion developed by the uncoordinated contraction of the muscle. The mechanism of the fracture should be recognized in order to prevent this type of fracture while playing baseball.
