Morton’s Neuroma occurs when the nerve between the 3rd and 4th metatarsal bones is squeezed. This region is particularly vulnerable to nerve impingement because it is where the lateral and medial plantar nerves join and typically the nerve is slightly thicker at this junction. This condition is similar to Metatarsalgia but includes a lack of sensation and tingling in the toes. This condition can be very painful at times.
Neuromas are defined as benign nerve tumours. Morton’s Neuroma is not a tumour. It is a swelling and thickening of tissue that surrounds the digital nerve. The digital nerve works to receive messages and relay actions to the toes.
What causes Morton's Neuroma?
The exact cause of this condition is not fully understood. It usually affects women over 50 and the condition is aggravated by tight-fitting footwear. Faulty foot mechanics (i.e. over-pronation) may be a contributing factor. The condition seems to occur in response to irritation, pressure or injury to one of the nerves that lead to the toes. The neuroma is part of your body's response to the irritation or injury. Often dropping of the metatarsal bones (as a result of over-pronation) contributes to the problem.
How can we treat this condition?
First of all a change in footwear is required. One must refrain from wearing any tight fitting shoes and wear a soft broad type of shoe with plenty of room in the toe box.
Rest, ice, anti-inflammatory medication can help ease the pain. Cortisone injections may resolve the pain in some people. If the neuroma is small in size a course of 5-6 injections of local anasthesetic around the neuroma can also be helpful.
A Morton's Neuroma operation involves removing the enlarged nerve by a cut made at the top of the foot. The deep transverse metatarsal ligament which causes the constriction above the nerve is released. The thickened nerve is then isolated from the surrounding tissue and cut where the nerve trunk appears normal again.
How orthotics can help
Footlogics Catwalk orthotics reduces symptoms of Morton’s Neuroma that occur while wearing women's fashion shoes. Orthotic insoles lift and support the forefoot to prevent the metatarsals from falling. This support helps prevent squeezing on the nerve, which relieves both tingling and pain arising from Morton’s Neuroma.
Morton’s Neuroma can also take place while wearing ordinary, flat shoes. Footlogics Medical orthotics provide metatarsal support and lifts the bone formation to avoid undue tension and chafing on the metatarsals. The support prevents abrasion and force on surrounding ligaments and nerves. When suffering from Morton’s Neuroma, it is recommended you seek the advice of a podiatrist. In some instances, surgery is required.
