Cause of Pain

• As the calcium deposits increase, the space decreases between the rotator cuff and acromion, which is the bony portion located at the top of the shoulder blade. This decreased space adversely affects normal function, leading to impingement, where the acromion and rotator cuff rub together when the arm is lifted.
  
  

Causes

• Although there are differing opinions between doctors and scientists as to why this condition develops, some doctors believe it may be caused by lack of blood flow to the tendon. Age is also a factor, as it usually does not occur until after the age of 30.
  
  

Diagnosis

• Your doctor will perform an X-ray or ultrasound to see if there are any calcium deposits.
  
  

Pain Management

• Anti-inflammatory medications may be prescribed if the condition does not resolve itself. A cortisone injection will relieve inflammation; however, some doctors will avoid this treatment since the tissue can weaken from overuse of cortisone.
  
  

Surgery

• When the calcium deposit has become very large, surgery may be considered. Surgery is used as a last resort when other treatment plans fail. It may be done arthrosopically or by open surgery.
  
  

Other Treatment

• Extracorporeal shock wave lithotripsy is a non-invasive treatment that uses shock waves to break the calcium deposits.
