Subacromial Bursa Injection (Shoulder)

A subacromial bursa injection is a minimally invasive procedure used to relieve shoulder pain and inflammation caused by bursitis or rotator cuff irritation. The subacromial bursa is a small, fluid-filled sac located under the acromion (top part of the shoulder blade) that helps cushion and reduce friction between tendons and bones in the shoulder.

When the bursa becomes inflamed (a condition called subacromial bursitis), it can cause significant pain, swelling, and limited shoulder movement. An injection of corticosteroid medication and local anesthetic into the bursa helps reduce inflammation and relieve symptoms.

Your provider may recommend this injection if you have:

• Subacromial bursitis
• Rotator cuff tendinitis or impingement syndrome
• Shoulder pain that worsens with lifting or overhead activities
• Persistent shoulder pain not responding to physical therapy, rest, or oral medications

The goal of the injection is to decrease inflammation, relieve pain, and improve shoulder function.

The procedure is typically performed in an outpatient setting.

• You will sit or lie comfortably with the shoulder exposed.
• The skin over the shoulder is cleaned and sterilized.
• A local anesthetic is used to numb the skin.
• Using ultrasound guidance (or anatomical landmarks), a small needle is inserted into the subacromial space.
• A combination of local anesthetic and corticosteroid medication is injected into the bursa.
• The entire procedure usually takes about 15–20 minutes, and you can typically return home shortly after.

• You may feel immediate pain relief from the local anesthetic, although this effect may wear off within a few hours.
• Steroid medication typically begins to reduce inflammation within 2–5 days.
• Mild soreness at the injection site is normal and usually resolves within 24–48 hours.
• Apply ice packs and limit strenuous activity involving the shoulder for 24–48 hours as advised.
• Most patients experience improved shoulder mobility and reduced pain for weeks to months after the injection.

Subacromial bursa injections are considered safe, but potential risks include:

• Temporary increase in pain after the injection
• Bruising or mild swelling at the injection site
• Infection (very rare)
• Allergic reaction to medications (extremely rare)
