Overview
Morton's neuroma is a benign neuroma of the interdigital plantar nerve. It is characterised by numbness and pain, relieved by removing footwear. Although it is labeled a "neuroma", many sources do not consider it a true tumor, but rather a thickening of existing tissue.
Historical Perspective
The condition was first correctly described by a chiropodist named Durlacher.
Pathophysiology
Causes
The exact cause is unknown.
Differentiating Morton's Neuroma from other diseases
Morton's neuroma must be differentiated from other causes of pain in the forefoot.
Epidemiology and Demographics
Morton neuroma is more common in women than in men.
Risk Factors
Risk factors for Morton's neuroma include abnormal positioning of toes, flat feet, forefoot problems, high foot arches, tight shoes and high heels.
Natural History, Complications and Prognosis
Morton's neuroma can make walking difficult. Nonsurgical treatment does not always improve symptoms.
History and Symptoms
Symptoms include: pain on weight bearing, frequently after only a short time; the pain is felt as a shooting pain affecting the contiguous halves of two toes. Burning, numbness and parasthesia may also be experienced.
