What is a bursa?

Bursae are small fluid-filled sacs that reduce friction around joints. When inflamed, they can cause pain and reduced movement, most commonly in the shoulder or hip.

Preparation

• Bring prior relevant imaging if done elsewhere.
• Inform us if you take blood thinners; some need stopping 5–7 days before.
• Arrange someone to drive you home.

Risks

This is a safe and commonly performed procedure. Temporary flushing or rash may occur. Steroids may raise blood sugar levels in diabetics. Rare risks include infection (<0.1%) and bleeding, especially in patients on blood thinners.

Procedure

The procedure takes about 15 minutes and is usually performed under ultrasound guidance. A fine needle is placed into the bursa and a mixture of local anaesthetic and steroid is injected. The anaesthetic wears off after a few hours, while steroid effects may take up to 2 weeks.

Aftercare

Mild soreness is common. Do not drive for the rest of the day. Rest the area for 48 hours, then gradually return to normal activities.

Effectiveness

The injection aims to reduce inflammation and pain. Relief duration varies and cannot be predicted.
