Complete tear of supraspinatus

complete tear of supraspinatus

The partial tear of the supraspinatus tendon is responsible for painful arc syndrome rather than a complete tear

Painful arc syndrome also known as impingement syndrome,is a clinical syndrome in which there is pain in the shoulder and upper arm during the mid range (between 60-120 degree) of shoulder abduction.this arises because of the repetitive rubbing of the supraspinatus tendon under the coracoacromial arch.

Cause include
-Minor tears of the supraspinatus tendon

-Chronic supraspinatus tendinitis

-calcification of supraspinatus tendon

-fracture of the greater tuberosity

-subacromial bursitis.
