What is it?

Small joint injections are used to treat arthritis-related pain in joints such as the thumb, fingers, and toes by reducing inflammation.

Preparation

• Bring prior relevant CT or MRI scans if done elsewhere.
• Inform us if you take blood thinners; some must be stopped 5–7 days before.
• Arrange someone to drive you home.

Risks

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

Procedure

The procedure takes approximately 15 minutes and is usually performed under ultrasound guidance. Local anaesthetic is used before a fine needle is placed into the joint and steroid with anaesthetic is injected. Steroid effects may take up to 2 weeks.

Aftercare

Mild soreness is common. Temporary pain relief may occur from the anaesthetic. Do not drive for the rest of the day. Rest for 48 hours, then gradually return to normal activity.

Effectiveness

The injection reduces inflammation and pain. Duration of relief varies between individuals. Repeat injections may occasionally be required at least one month apart.
