Shoulder surgery is typically recommended when shoulder bursitis is chronic and related shoulder impingement. The type of surgery performed will depend on the patient’s symptoms and the underlying cause of the shoulder pain.
The 3 surgical procedures typically recommended include:
The inflamed bursa is removed in a procedure called a bursectomy. This may be done with a single open incision or arthroscopically (which requires 2 or 3 small incisions).
After a bursa is removed, a new bursa may form in its place. The hope is that the newly formed bursa is less prone to irritation and causing painful symptoms.
2. Subacromial Decompression (Acromioplasty)
During subacromial decompression the surgeon removes or shaves down part the shoulder blade’s acromion. By removing bone tissue, the surgeon creates more space for the shoulder’s soft tissues, including the rotator cuff, tendons, and the subacromial bursa.
The hope is that by giving these soft tissues more space they will be less likely to become irritated and inflamed and create painful symptoms. Removing bone does not typically affect the shoulder joint’s long-term function.
This surgery is most likely to be recommended if the acromion is curved or hook-shaped (as opposed to flat), as experts believe these shapes increase the likelihood for impingement.
3. Tendon and Muscle Repair
When shoulder bursitis or impingement is caused by damage to a rotator cuff muscle or tendon, a doctor may recommend surgery to correct the damage. For example, a torn tendon may be repaired and reattached to the humeral head.
Some experts believe the majority shoulder bursitis cases originate from tears in the rotator cuff muscles.1
Deciding if Surgery Is Necessary
Moreover, some experts suggest that nonsurgical treatments are appropriate in most cases. More research is needed in this area. The exception is when bursitis and shoulder impingement are caused by rotator cuff tears; in these cases, experts seem to agree that surgery to repair the rotator cuff is appropriate.4
After surgery, the patient may be asked to wear a sling for a set period of time and participate in physical therapy.
