Rotator Cuff Tears: Partially Torn Rotator Cuff

Print PDF Version - Partially Torn Rotator Cuff


This condition is caused when the rotator cuff tendons rub the underside of the acromion bone. Chronic rubbing can lead to a weakening and even tearing of the rotator cuff. Symptoms include pain, weakness and loss of motion.

Rotator Cuff Pain

The underside of the acromion bone rubs the rotator cuff tendons causing pain and weakness. More space will be created for the rotator cuff by removing part of the acromion.


Small incisions (portals) are made around the joint. The scope and surgical instruments will go into these incisions.


The scope is inserted into the back of the shoulder joint. Saline solution flows through a tube (cannula) and into the bursa sac to expand the joint and to improve visualization. The image is sent to a video monitor where the surgeon can see inside the joint.

Bursa Sac Bone Spur Removal

A specialized surgical instrument is used to remove the inflamed and irritated bursa sac. A surgical shaver or burr is then used to remove bone from the underside of the acromion. More space is created for the rotator cuff tendons.

Shaving Frayed Rotator Cuff Edges

If less than 50% of the rotator cuff tendon is torn, The shaver is used to remove the frayed edges of the rotator cuff. If more than 50% is torn, a repair is usually performed.

End of Procedure

After more space has been created for the rotator cuff and the frayed edges have been trimmed, the procedure is completed.
