Multifocal motor neuropathy
Multifocal motor neuropathy (MMN), also known as multifocal motor neuropathy with conduction block, is a rare autoimmune peripheral neuropathy, which primarily affects the upper limbs, with insidious deterioration over decades.
Epidemiology
Multifocal motor neuropathy typically affects young ...
Article
Sciatic neuropathy
Sciatic neuropathy can be the result of nerve compression or traction injury of the sciatic nerve which might occur at several levels along its course. The peroneal division of the nerve is more commonly affected than the tibial division due to the more superficial location and two different fix...
Article
Riche-Cannieu anastomosis
Riche-Cannieu anastomosis describes a common interneural communication between the median nerve and the ulnar nerve in the hand.
Gross anatomy
Generally, this anastomosis is specifically between the deep palmar branch of the ulnar nerve and the recurrent branch of the median nerve, although ma...
Article
Superficial peroneal nerve entrapment
Superficial peroneal nerve entrapment or compression syndrome is a nerve compression syndrome of the superficial peroneal nerve a mixed motor and sensory nerve providing the motor innervation of the peroneus longus and peroneus brevis muscles and sensory innervation of the dorsum of the foot and...
Article
Medial plantar nerve entrapment
Medial plantar nerve entrapment or compression syndrome, also known as jogger’s foot is a nerve compression syndrome of the medial plantar nerve either in the distal tarsal tunnel or beneath the plantar arch at the knot of Henry.
Epidemiology
Medial plantar nerve entrapment is a rather rare ty...
Article
Tarsal tunnel syndrome
Tarsal tunnel syndrome refers to an entrapment neuropathy (tunnel syndrome) of the (posterior) tibial nerve or of its branches within the tarsal tunnel. This condition is analogous to carpal tunnel syndrome.
Clinical presentation
The most common symptoms are pain and paresthesia in the toes, s...
Article
Tunnel syndrome
A tunnel syndrome refers to pain, paresthesia and weakness due to neurovascular compression, friction or traction within a confined anatomical passageway. The tunnel may be bordered by bone, muscle or tendoligamentous structures or a combination of these.
Various specific syndromes exist and ar...
Article
Martin-Gruber anastomosis
Martin-Gruber anastomosis is a common type of, and is the most clinically relevant, interneural communication between the median nerve and ulnar nerve in the forearm.
Gross anatomy
Most commonly, motor fibers from the median nerve cross to join the ulnar nerve, although at least four patterns ...
Article
Marinacci anastomosis
Marinacci anastomosis, also known as reverse Martin-Gruber anastomosis, describes a rare interneural communication between the ulnar nerve and the median nerve in the distal forearm.
Gross anatomy
Most commonly, motor fibers from the ulnar nerve cross to join the median nerve in the distal for...
Article
Deep peroneal nerve entrapment
Deep peroneal nerve entrapment or compression syndrome anterior is a nerve compression syndrome of the deep peroneal nerve and might occur within the anterior tarsal tunnel beneath the inferior extensor retinaculum as anterior tarsal tunnel syndrome.
Epidemiology
Deep peroneal nerve entrapment...
Article
Sural neuropathy
Sural neuropathy, also known as sural nerve entrapment, can be the result of nerve compression or traction injury of the sural nerve. This nerve is a purely sensory branch, usually formed by a confluence of branches from the tibial nerve and common peroneal nerve that supplies the lateral aspect...
Article
Transthyretin amyloidosis
Transthyretin (ATTR) amyloidosis is a form of systemic amyloidosis characterized by the misfolding, aggregation and deposition of transthyretin-related (TTR) protein in various organs 1-6. This can occur in the following two forms namely in the setting of a genetically normal transthyretin-relat...
Article
Berrettini anastomosis
Berrettini anastomosis is a common sensory interneural communication between the ulnar nerve and the median nerve in the palmar surface of the hand.
Gross anatomy
The Berrettini anastomosis is a purely sensory anastomosis between the common palmar digital nerves that arise from the median and ...
Article
Phrenic nerve palsy
Phrenic nerve palsy (also known as phrenic nerve paresis or paralysis) has many causes and can be caused by lesions anywhere along the course of the phrenic nerve, as it travels from the neck, to pierce the diaphragm adjacent to the pericardium.
Epidemiology
No single demographic is affected, ...
Article
Saphenous neuropathy
Saphenous neuropathy or saphenous nerve entrapment can be the result of nerve compression or traction injury of the saphenous nerve a pure sensory nerve terminal branch and the longest cutaneous branch from the femoral nerve that supplies the medial thigh, lower leg and foot 1-3.
Epidemiology
...
Article
Guillain-Barré syndrome
Guillain-Barré syndrome (GBS) is a heterogeneous group of autoimmune polyradiculopathies, involving sensory, motor, and autonomic nerves. It is the most common cause of rapidly progressive flaccid paralysis. It is believed to be one of a number of related conditions, sharing a similar underlying...
Article
Nerve compression syndrome
Nerve compression syndromes or nerve entrapment neuropathies are a group of several nerve disorders associated with sensory and/or motor loss resulting from nerve compression.
Epidemiology
Nerve compression syndromes are common 1-5 and can account for 10-20% of cases in specialist clinics of n...
Article
Ulnar nerve
The ulnar nerve is one of the terminal branches of the brachial plexus and has a motor and sensory supply to the forearm and hand.
Summary
origin: medial cord from roots C8-T1
course: medial to the axillary artery to descend downwards and pass posterior to the medial epicondyle of the humerus...
Article
Hypomyelinating disorders
Hypomyelinating disorders are a heterogeneous subset of white matter disorders characterized by abnormally low amounts of myelination.
In distinction to other myelin disorders, hypomyelination is a permanent deficiency in myelin deposition rather than myelin destruction (i.e. demyelination) or ...
Article
Mononeuritis multiplex
Mononeuritis multiplex, also known as mononeuropathy multiplex, is a disorder involving two or more asymmetric peripheral nerves and is usually seen as a complication of an underlying condition 1-7. It has an acute or subacute onset and can progress to involve more nerves and develop into a poly...
