What is edema in the subacromial subdeltoid bursa?

Subacromial-subdeltoid bursitis

The subacromial-subdeltoid (SASD) bursa is a synovial fluid-lined space that lies between the acromion and the deltoid muscle. It protects the tendons of the supraspinatus, infraspinatus, and teres minor muscles as they pass beneath the acromion.

Subacromial-subdeltoid bursitis is a common condition that causes shoulder pain and stiffness. It often occurs after overuse of the shoulder, such as from throwing or weight lifting. It can also be caused by trauma, such as a fall.

Symptoms of subacromial-subdeltoid bursitis include:

- Shoulder pain

- Pain that worsens with overhead activities

- Swelling in the front of the shoulder

- Tenderness to the touch

- Stiffness in the shoulder

- Crepitus (a grinding sensation) when the shoulder is moved

Treatment for subacromial-subdeltoid bursitis typically involves rest, ice, and anti-inflammatory medications. In some cases, physical therapy may be helpful. If symptoms do not improve, corticosteroid injections may be recommended. In rare cases, surgery may be necessary.
