Causes of Shoulder Impingement
Since the space through which the rotator cuff tendons need to pass is already narrow, any further narrowing due to inflammation or irritation can cause impingement syndrome.

 

Symptoms of Shoulder Impingement
Symptoms of shoulder impingement include:
- decreased movement
- pain at night
- weakness
- popping or grinding in the shoulder
 

Diagnosis of Shoulder Impingement
A thorough physical examination and history is important to diagnose shoulder impingement. X-rays can help detect issues in the bone and an MRI is needed at times to analyze soft tissue in the shoulder.

 

Treatment for Shoulder Impingement
Non-surgical Treatment

A cortisone injection can be helpful to diminish some inflammation. If there is uncertainty about whether or not the cause is impingement versus a rotator cuff tear, a MRI will often confirm the diagnosis. If impingement fails to respond to conservative care, it can be treated with arthroscopic debridement of the impinged tissue to create more space for the rotator cuff.
