The two kinds of surgery for Morton's neuroma involve cutting ligaments that hold some of the bones in the affected toes or removing the neuroma itself, according to Mayo Clinic. Since the neuroma contains nerve cells, there is a risk of permanent numbness in the space between the toes.
Orthopaedic surgeons consider surgery the treatment of last resort for Morton's neuroma, states the National Health Service. Surgery is undertaken if no other treatment works. Morton's neuroma surgery is usually performed under local anesthesia and is an outpatient procedure. After the area is numbed, the surgeon makes an incision on the top or bottom of the foot.
Many surgeons prefer to operate on the top of the foot, as operating from the bottom may necessitate the use of crutches, explains Dr. Kirk A. Koepsel for PodiatryNetwork.com. The bottom of the foot also takes longer to heal.
Patients need to wear special footwear for about a month after surgery to allow the surgical wound to heal properly, notes the National Health Service. Most people who have the surgery are free of the symptoms of Morton's neuroma. Besides permanent numbness, other surgery complications include thickening skin on the bottom of the affected foot and infection.
