Also known as Morton’s Interdigital Neuroma, Morton’s Metatarsalgia, Morton’s Neuralgia, Plantar Neuroma, Intermetatarsal Neuroma) What is a Morton’s neuroma? Morton’s neuroma is a condition characterized by localized swelling of the nerve and soft tissue located between two of the long bones of the foot (metatarsals – figure 1), which can result in pain, pins and needles, or numbness in the forefoot or toes.
Inappropriate footwear is one of the principle causes of Morton?s neuroma. Toe spring and tapering toe boxes are the most problematic shoe design features that contribute to this health problem. Morton?s neuroma occurs when one of your nerves is stretched and pinched, which happens with great frequency in people who wear shoes incorporating these design features. A professional shoe fitting should always be sought if you are struggling with neuroma-related symptoms.
Symptoms of interdigital neuroma typically manifest as a sharp, burning or tingling sensation in the forefoot. The pain radiates toward the lesser toes and is aggravated by shoe wear. The pain is relieved when the shoe is removed and the forefoot is massaged. Sometimes the symptoms involve specific toes.
If you suspect Morton?s Neuroma, it is essential that you confirm your suspicions by consulting with a podiatric physician. Don?t wait for the symptoms to go away for good (even if they tend to come and go). Also, remember that many conditions have similar symptoms, and only a professional can tell the difference.
Non Surgical Treatment
Wearing shoes that provide enough room in the toe box is also the first step in treating Morton?s neuroma. For instant relief when pain flares up, try taking your shoes off and rubbing the area. The nerve can get trapped below the ligament, and rubbing can move it back to its natural position. Your doctor or a foot-care specialist may recommend lower heels and metatarsal pads. These pads provide cushioning under your neuroma and better arch support to redistribute your weight. If you keep pressure off the toes and wear wide enough shoes, the problem may gradually disappear.
Surgery to excise the neuroma is usually performed under general anaesthetic in a day surgery facility. After surgery you will have to keep your foot dry for two weeks. Generally neuroma surgery allows for early weight bearing and protection in some type of post op shoe gear. Some neuromas may reoccur, but this is rare. Most studies on patient satisfaction after neuroma surgery show approximately 90% reduction of pain and about 85% of all patients rated the overall satisfaction with the results as excellent or good.
