Subacromial bursitis is a condition characterized by inflammation of the subacromial bursa, a small fluid-filled sac located between the rotator cuff tendons and the acromion bone of the shoulder blade. This condition is common in people who engage in activities that involve repetitive overhead movements, such as throwing a ball, swimming, or painting.
Symptoms
- Pain in the front, side or top of the shoulder that worsens with movement
- Swelling or tenderness in the affected area
- Limited range of motion in the shoulder
- Weakness in the shoulder
Causes
- Repetitive overhead movements
- Trauma or injury to the shoulder
- Arthritis or degenerative changes in the shoulder joint
- Infection
Risk factors
- Age (more common in people over 40 years old)
- Participation in sports or activities that involve repetitive overhead movements
- Poor posture or biomechanics
- Bone spurs or other structural abnormalities in the shoulder
Associated conditions
- Rotator cuff tears
- Shoulder impingement syndrome
- Frozen shoulder
Diagnosis
- Physical examination, including range of motion and strength testing
- Imaging tests, such as X-rays or MRI, to evaluate the extent of inflammation or damage in the shoulder joint
Differential diagnosis
- Rotator cuff tears
- Shoulder impingement syndrome
- Frozen shoulder
- AC joint injuries
Treatment options
- Rest and avoiding activities that aggravate the condition
- Ice therapy to reduce inflammation and pain
- Nonsteroidal anti-inflammatory drugs (NSAIDs) to relieve pain and inflammation
- Physical therapy to improve range of motion and strengthen the shoulder muscles
- Corticosteroid injections to reduce inflammation and pain
- Surgery in severe cases
Typical recovery timeframes
- Recovery timeframes vary depending on the severity of the condition and the individual’s response to treatment.
- With appropriate treatment, most people with subacromial bursitis can expect to see improvement within a few weeks to a few months.
Prognosis
- With prompt and appropriate treatment, most people with subacromial bursitis can expect to fully recover and return to their normal activities.
- In some cases, chronic bursitis can lead to long-term pain and limited range of motion in the shoulder.
