Why do pitchers get rotator cuff injuries?
Pitchers frequently sustain partial rotator cuff tears; this may be due to the repetitive overhead throwing, which overloads the shoulders causing internal impingement7 and damage to the superoposterior labrum. In turn, this can lead to pseudo-instability and limitation in the range of motion.
Which muscle is considered a rotator cuff muscle?
