Why use ultrasound guidance for a Morton’s neuroma injection?
Short answer: Ultrasound guidance allows the needle and medication to be positioned around the intended nerve while avoiding adjacent joints, vessels and soft tissues as far as practicable.
The intermetatarsal space is small and individual anatomy varies. Real-time imaging confirms the target, shows medication spread and reduces reliance on surface landmarks alone.
A 2024 Cochrane review found ultrasound-guided corticosteroid plus local anaesthetic probably reduced pain more than non-guided injection at six months. Guidance improves precision; it does not guarantee response.
