Peripheral neuropathies
Canal syndromes
Root canal syndromes: definition Nerve compression syndromes, called “ductal syndromes” (entrapment neuropathy in the English) are defined as the clinical translation of a conflict between a peripheral nerve trunk and a particular anatomical region of
Tarsal tunnel syndrome
Pathophysiology. Tarsal tunnel syndrome is a tunnel syndrome characterized by compression of the posterior tibial nerve and/or its distal terminal branches by the internal annular ligament. The posterior tibial nerve gives, in the retro-malleolar region,
Ulnar canal syndrome at the elbow
Anatomical reminder 1- Radial nerve 2- vessels 3-Median nerve 4- Brachialis muscle 5- Humerus 6-Ulnar nerve 7- Olecranon The ulnar nerve travels in the epitrochleo-olecranon groove on the inner side of the elbow. It relates
Carpal tunnel syndrome MEDECIN
Anatomical reminder Carpal tunnel syndrome is linked to compression of the median nerve in the wrist. The carpal tunnel is a narrow tunnel formed posteriorly by the carpal bones and anteriorly by the anterior annular
Cervico-thoracic outlet syndrome
Anatomical reminder Cervico-thoracic parade syndrome corresponds to the compression of the brachial plexus (all of the upper limb nerves), the subclavian artery and/or the subclavian vein in the passage formed by the inter-scalènic parade and
Cicatricial neuropathy
A new concept: Cicatricial neuropathy. The most misunderstood and yet the most frequent of the neuropathies responsible for neuropathic pain. Indeed, a recent study carried out by a Parisian pain center finds an incidence between
Pudendal nerve neuralgia MEDECIN ABONNE
Pathophysiology of neuralgia of the pudendal nerve Classic pudendal nerve neuralgia is a tunnel syndrome (like carpal tunnel syndrome). There are two areas of possible conflict in the pelvic area: at the level of the
Peripheral neuropathies MEDECIN ABONNE
Definition. The peripheral nervous system is composed of: – Spinal nerve roots, – the posterior spinal ganglia, – the peripheral nerves up to their terminal ramifications, – the autonomic nervous system, – the cranial nerves
Peripheral nerves
Nerves are formed by the axons of nerve cells (the axon is an extension of the nerve cell). These axons are or are not surrounded by myelin sheath from other cells: Schawnn cells. Anatomy: A
