Abstract

Abdominal oblique muscle injuries are relatively common in professional baseball players and can result in substantial loss of playing time. It is usually caused by a sudden movement of the torso in sports involving repetitive activity requiring trunk rotation and it tend to occur on the contralateral side of the dominant arm. We report a unique case of sequentially occurred bilateral abdominal internal oblique muscle rupture in a right-handed professional baseball batter over two seasons. Each internal oblique rupture had a different mechanism of the injury, the non-dominant side occurred during bat swing and the dominant side during bent leg sliding. After rest and rehabilitation, each injury was recovered to play in about 1 month.
