The following pages will deal with compression neuropathies (carpal tunnel syndrome, ulnar neuropathy etc.), injury to peripheral nerves & the brachial plexus, nerve tumours, facial palsy and nerve related pain
This site will also inform patients about the care they receive and prepare them accordingly in order to maximize their results [however, be aware that the conditions shown here as examples may or may not precisely resemble yours].
Peripheral nerves are anatomical structures that relay information and commands from the target organs to the central nervous system and vice versa. In this manner, the skeletal muscles contract and relax upon volitional command from the central nervous system, relayed through the peripheral nerves; the sensation of the surface of the skin is relayed to the brain for recognition and reaction through the peripheral nerves. The third, no less important function is the regulation of vegetative mechanisms, such as constriction and relaxation of blood vessels, sweating patterns, growth, cell migration.
Consequently, malfunction of a peripheral nerve may cause loss or alteration of sensation of an area of skin, paralyses and wasting of muscles, and pain. The extent of resulting symptoms depends on the level and severity of injury.
Nerve lesions can be generally subdivided into the following categories:
(1) Spontaneous focal neuropathy
- compression of a single nerves (pinched nerve)
- as part of a systemic disease, e.g., polyneuropathy, diabetes, mycobacterial infection etc.
(2) Nerve injury
- open injury – as in gunshot wounds, stab injuries, iatrogenic injury.
- closed- as in stretch and/or torsion injury of the brachial plexus and other nerves.
(3) Facial palsy
- acquired, viz., post traumatic, iatrogenic
- congenital, such as Möbius syndrome
(3) Tumors, benign or malignant
- of single nerves (e.g., schwannoma, MPNST)
- as part of a systemic disease (e.g., neurofibromatosis)
- as part of a regional disease (e.g., schwannomatosis)
(4) Nerve pain
