A neuroma is a thickening of nerve tissue that may develop in various parts of the body. The most common neuroma in the foot is a Morton’s neuroma, which occurs between the third and fourth toes. Neuromas may also occur in other locations on the foot. The incidence of Morton's neuroma is 8 to 10 times greater in women than in men.
The thickening, or enlargement, of the nerve that defines a neuroma is the result of compression and irritation of the nerve. This compression creates enlargement of the nerve and could eventually lead to permanent nerve damage.
If you have a Morton’s neuroma, you may have one or more of these symptoms where the nerve damage is occurring:
The progression of a Morton’s neuroma often follows a typical pattern:
Anything causing compression or irritation of the nerve can lead to the development of a neuroma. One of the more common offenders is wearing shoes that have a tapered toe box or high-heeled shoes that cause the toes to be forced into the toe box.
People with certain foot deformities, such as bunions, hammertoes, flatfeet, or more flexible feet, are at a higher risk for developing a neuroma. Other potential causes include activities that involve repetitive irritation to the ball of the foot, such as running or court sports. An injury or other type of trauma to the area may also lead to a neuroma.
The best time to see your Celebration Orthopaedics foot and ankle surgeon is early in the development of symptoms. Early diagnosis of a Morton’s neuroma greatly lessens the need for more invasive treatments and may help you avoid surgery.
In developing a treatment plan, your doctor will first determine how long you’ve had the neuroma and evaluate its stage of development. Treatment approaches vary according to the severity of the problem.
For mild to moderate neuromas, treatment options may include:
Surgery may be considered in patients who have not responded adequately to non-surgical treatments. Your foot and ankle surgeon will determine the approach that is best for your condition.
Regardless of whether you’ve undergone surgical or nonsurgical treatment, your Celebration Orthopaedics surgeon will recommend long-term measures to help keep your symptoms from returning. These include appropriate footwear and modification of activities to reduce the repetitive pressure on the foot. The length of the recovery period will vary, depending on the procedure performed.
