Diabetic foot ulcer is a breakdown of the skin and sometimes deeper tissues of the foot that leads to sore formation. It is thought to occur due to abnormal pressure or mechanical stress chronically applied to the foot, usually with concomitant predisposing conditions such as peripheral sensory neuropathy, peripheral motor neuropathy, autonomic neuropathy or peripheral arterial disease.

There is always a noticeable difference in the compound muscle action potential's dispersion, and conduction block is commonly experienced. [ 26 ] An MRI can show proximal nerve or root enlargement and gadolinium enhancement, which indicate active inflammation as well as demyelination in the brachial plexus [ 27 ] or cauda equina .
Peripheral neuropathy may be classified according to the number and distribution of nerves affected (mononeuropathy, mononeuritis multiplex, or polyneuropathy), the type of nerve fiber predominantly affected (motor, sensory, autonomic), or the process affecting the nerves; e.g., inflammation (), compression (compression neuropathy), chemotherapy (chemotherapy-induced peripheral neuropathy).
Radiculopathy (from Latin radix 'root'; from Ancient Greek πάθος (pathos) 'suffering'), also commonly referred to as pinched nerve, refers to a set of conditions in which one or more nerves are affected and do not work properly (a neuropathy). Radiculopathy can result in pain (radicular pain), weakness, altered sensation (paresthesia) or ...
Diabetic foot conditions can be acute or chronic complications of diabetes. [1] Presence of several characteristic diabetic foot pathologies such as infection, diabetic foot ulcer and neuropathic osteoarthropathy is called diabetic foot syndrome. The resulting bone deformity is known as Charcot foot.
Diabetic neuropathy can affect any peripheral nerves including sensory neurons, motor neurons, and the autonomic nervous system. Therefore, diabetic neuropathy has the potential to affect essentially any organ system and can cause a range of symptoms. There are several distinct syndromes based on the organ systems affected.

Neuropathic arthropathy (also known as Charcot neuroarthropathy or diabetic arthropathy) refers to a progressive fragmentation of bones and joints in the presence of neuropathy. [1] It can occur in any joint where denervation is present, although it most frequently presents in the foot and ankle. [2]
Neuropathy can lead to a loss of sensation for diabetics in their feet, therefore when there is any trauma/injury or foot ulcer present in these patients it can take awhile for patients to notice; this can lead to an infection developing and worsening while the patient is unaware due to the loss of sensation and lack of pain.
