Instrumental and clinical diagnosis of interdigital Morton neuroma

Background: Interdigital neuroma is one of the most common diseases in foot surgery. It is a common cause of metatarsalgia leading to debilitating pain. At the same time, the diagnosis of neuroma can be a difficult task for an orthopedic surgeon due to the complex anatomy of the forefoot and a large number of soft-tissue and bone structures. Besides, the existing manual testing methods are not pathognomonic specifically for neuroma. The clinical symptoms and history, as well as a physical exam and instrumental evidence are important in assessing and grading the disease. However, there are no recommendations in the modern Russian literature regarding the need for routine visualization of neuroma. The reproducibility of the study, the absence of ionizing radiation and the possibility of obtaining a second opinion, as well as high sensitivity makes magnetic resonance imaging an important diagnostic tool in the diagnosis of neuroma.
