Morton's Neuroma Excision
Removing Morton's neuroma is a surgery commonly used when conservative treatment has failed. This page will explain how why it is performed, and outline the common risks.
Why have the surgery?
Certain nerves travel down the foot and end up in the toes, where they provide a sensory function. These nerves are subject to being squeezed on and this can lead to a compensatory fibrosis or scarring which forms in to a lump. This lump is known as a Morton's neuroma and surgery to take it out is needed if pain does not get better with physiotherapy, insoles or injections.
How is surgery performed?
The operation is typically performed under a general anaesthetic. An incision is made close to the affected webspace and the nerve is cut and removed. It is not possible to remove just the fibrous tissue unfortunately.
What are the benefits?
The operation carries a high chance or relieving the nerve pain, which in turn should help standing, walking and wearing closed shoes.
What are the risks?
All operations have risks, but the commonest and most concerning for this surgery are: - Stump neuroma, meaning that the end of the cut nerve forms into a swelling and creates recurrent pain. - Painful scarring. - Numbness in the toes, which occurs due to the removal of the nerve. This list is not exhaustive and Mr Patel can talk you through them all in more detail during a consultation.
What recovery is involved?
The foot will dressed in a bulky dressing for two weeks, during which time the foot must be kept dry and elevated. These dressings are removed after two weeks, which allows wide-fitting shoes to be worn, the scar to be massaged and the toes to be stretched, which all helps reduce swelling.
Any other considerations?
The majority of patients presenting with a Morton's neuroma will have developed the condition due to tight calves and forefoot overload. Surgery should only be considered if these have explored and addressed.
