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.
SurgeryA 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 helpFootlogics 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.
