Shoulder diagramSubacromial decompression is a relatively non-invasive arthroscopic procedure to treat subacromial impingement syndrome. Subacrominal impingement is a condition where the rotator cuff tendon is pinched between the humeral head and the under surface of the acromion. Your physician may recommend arthroscopic subacromial decompression if conservative treatments, such as medications and physical therapy, fail to resolve your symptoms.


  • Pain in the top and outer side of your shoulder

  • Pain that worsens when you lift your arm up

  • Aching or pain at night

  • Weakness in your arm

You can watch the video below for a general demonstration of a subacromial decompression procedure.  However, actual decompression surgiers may vary according to an individual patient’s unique condition.
