Rotator Cuff Signs: Empty Can Test

The supraspinatus is the most commonly injured rotator cuff  muscle.  It originates from the shoulder blade passes laterally beneath acromion and attaches onto the humerus.supraspinatus-lateral1supraspinatus

The supraspinatus  stabilizes the shoulder joint and allows one to raise their arm in a plane similar to a jumping jack.

The empty can test assesses the supraspinatus for instability and the presence of tears.  The test is conducted as follows:

The patient raises his arm to 90 degrees and angles the arm forward 30 degrees at the shoulder joint.  The shoulder is then internally rotated as if pouring a can on the floor.  Resistance is applied looking for weakness or pain. The test is positive if there is significant pain or weakness or resistance.

Rotator cuff tears which do not response to physical therapy can be treated with expanded stem cells.  At Regenexx patients use their own stem cells to repair damaged tendons, ligaments, bones and cartilage.

1 inch supraspinatus rotator cuff tear

The rotator cuff is compromised for four principle muscles:  the supraspinatous, teres minor, subscapularis and infraspinatus.  A rotator cuff tear  is usually the result of a sudden powerful raising of the arm against resistance.  Common examples include heavy weightlifting or falling on an outstretched arm.  Acute tears are associated with severe pain often shooting down the arm, limited range of motion and point tenderness at the site injury.

The supraspinatus originates from the scapula (shoulder blade)  and attaches via a  tendon to the humerus.  It functions to stabilize the shoulder joint and enables one to raise their arm in the plane similar to a jumping jack.

Supraspinatus rotator cuff tears are often treated with surgery where the tendon is reinforced and stapled onto the humerus.  The surgery requires rotator cuff rehabilitation which can be painful and extensive. 

Stem cell therapy is now an alternative therapy for partial tears of the rotator cuff.  At Regenexx patients are able to use their own stem cells to repair partial tears in tendons and ligamentsRegenexx is a simple needle-in, needle-out procedure which enables patients to forgo surgery and the extensive rehabilitative process typically associated with rotator cuff surgery.

Please see images below where a patient used their own stem cells to repair a partial supraspinatus tear.
