Nerve compression syndrome, or compression neuropathy, or nerve entrapment syndrome, is a medical condition caused by chronic, direct pressure on a peripheral nerve. [1] It is known colloquially as a trapped nerve, though this may also refer to nerve root compression (by a herniated disc, for example).
The brachial plexus innervates the upper extremity as well as some muscles in the neck and shoulder. [4] Damage to the brachial plexus can occur when the nerves are stretched too far from the head and neck; specifically the upper trunk of the plexus – nerve roots at the 5th and 6th cervical level – are primarily affected.
For this reason, a nerve resection may be considered after a failed decompression. Examples of nerves that may be good candidates for resection are lateral femoral cutaneous nerve, [42] zygomaticotemporal branch of the trigeminal nerve, [43] the posterior femoral cutaneous nerve, [44] [45] and the middle/superior cluneal nerves. [46]
Pinched nerves arise when surrounding bone or tissue, such as cartilage, muscles or tendons, put pressure on the nerve and disrupt its function. [ 2 ] In a radiculopathy, the problem occurs at or near the root of the nerve, shortly after its exit from the spinal cord .
Nerve injury is an injury to a nerve.There is no single classification system that can describe all the many variations of nerve injuries. In 1941, Herbert Seddon introduced a classification of nerve injuries based on three main types of nerve fiber injury and whether there is continuity of the nerve. [1]
Sitting in a good posture with a good ergonomic chair will help keep your neck in a good posture when adjusted appropriately. If you are sitting or standing in a poor posture overtime it can lead ...
The sciatic nerve forms the roots of L4-S3 segments of the lumbosacral plexus. The nerve will pass inferiorly to the piriformis muscle, in the direction of the lower limb where it divides into common tibial and fibular nerves. [7] Symptoms may include pain and numbness in the buttocks and down the leg.
It is also known as brachial plexitis, and results in brachial plexus inflammation without any apparent shoulder injury. PTS can manifest with severe pain in the shoulder or arm, followed by numbness and weakness. [5] Parsonage–Turner syndrome occurs in about 1.6 out of 100,000 people every year. [6]
