In the images on the left you can see examples of rotator cuff tears. In the image on the right, the red arrow is pointing to the tear in this MRI image. The white area is the actuall tear in the tendon.
Rotator cuff tears in volve one or more of the four tendons of the rotator cuff muscles. The tear will likely occur at the point of attachment to the tubercle of the humerus bone.
Rotator cuff tears are the most common of shoulder injuries, the supraspinatus muscle being the on the giving the most trouble.
Often rotator cuff tears will present with little or no pain, and have no symtoms at all. The most obvious cause of these tears are aging and degeneration related to age.
Diagnosing may be difficult as symtoms may be intermittent or only present when active. Pain may be mild to severe with some possible weakness. An MRI would be the modality of choice to prove the rotator cuff tear, with surgical resection to follow.
