Compression neuropathy is the a group of peripheral nerve disorder due to be under pressure. It is charecterized by pain in the nerve distribution , paresthesia or loss of fuction.
Most often , the nerve exposed to pressure in the fibroosseous ( carpal or tarsal tunnel ) and origin of some muscle ( cubital tunnel ).
Nearly all of the compression neuropathies close to the extemity articulations.
COMPRESSION NEUROPATHIES OF THE UPPER EXTREMITY
- Thoracic Outlet syndrome
- Axillary nerve
- Suprascapular nerve
- Spinal accessory nerve
- Median nerve
- Pronator nerve
- Carpal tunnel syndrome
- Ulnar nerve
- Cubital tunnel syndrome
- Radial nerve
THORACIC OUTLET SYNDROME
Thoracic outlet syndrome consists of a series of symptoms that affect the shoulder , arm or hand due to pressure over the nerves and blood vessels at the upper chest.
“ Thoracic outlet “ is the name of the space between clavicle and the first rib. It can be become narrow or get damage because of the accident , pregnancy and congenital development differences. It causes pain and numbnes on the related arm because of the compression on the nerves and blood vessels which pass through this region.
Thoracic outlet syndrome can accur at any age . Especially , it is more common in athletes with playing tennis and volleyball in comparison with society.
CARPAL TUNNEL SYNDROME
Carpal tunnel sydnrome is a disease caused by the compression of the median nerve in the canal in the wrist.
“ Carpal canal “ is in the wrist level and covered by a thick band at the top.
The tendons and median nerve that provide finger movements are located in this channel.The median nerve provides sensation of the 4 fingers ( thumb,index,middle finger and ring finger ) . Also , it allows to do some finger movements. The reasons of the narrowing channel may be cause hand-wrist diseases .
CUBITAL TUNNEL SYDROME
The cubital tunnel syndrome is adisease that caused by compression or being exposed to pressure of the ulnar nerve and charecterized by pain , swelling , numbness and loss of strength.
Ulnar nerve passes through between 2 bony prominences and the 2 origins of the flexor carpi ulnaris. The nerve quite prone to trauma and compression because it is superficial at this region.
