The rotator cuff is compromised for four principal muscles which stabilize the shoulder.

Pain in the shoulder joint can arise for many sources which include, muscle inhibition, muscle tear, shoulder impingement, inflammation of the bursa and tears or degeneration in the labrum.

Rotator cuff tear sugery is a common technique which is used.  It has risks including but not limited to the risk of anesthesia, nerve damage and extensive rehabitilation.  Have you ever seen someone at the store with their arm in a restrictive brace?  They have probably had arthoscopic shoulder surgery or rotator cuff tear surgery.  Please view the procedure.


Alternatively one can now use their own stem cells to regenerate a torn muscle or ligament in the shoulder area.  AtRegenexx we have successfully healed a torn supraspinatous with a patient’s own stem cells who  had failed rotator cuff tear surgery.

In contrast to surgery, this is a needle in, needle out procedure with minimal down time and no need for restrictive braces. In addition at the Centeno-Schultz Cinic we focus on the biomechanics of the shoulder to ensure maximal outcome.  This may include myofascial deactivation of one of the four muscles listed above or prolotherapy to tighten lax ligaments.

The supraspinatous abducts the arm.

The infraspinatous laterally rotates the arm.

The teres minor laterally rotates the arm,

The subscapularis medially rotates the humerus
