More Information about the Infraspinatus Muscle
Infraspinatus is derived from the Latin words 'infra' meaning beneath and 'spina'
meaning spine. The infraspinatus
muscle which is assisted by the teres minor is the second most commonly
injured rotator cuff muscle. behind the supraspinatus.
The infraspinatus works along with the other rotator cuff muscles to produce
dynamic caudal glide in the glenoid fossa which helps prevent impingement.
