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).
1. a herniated disc when other non-surgical treatments have failed. The nucleus pulposus (the jelly-like center of the disc) of the herniated disc bulges out through the annulus (surrounding wall) and presses on the nerve root next to it. 2. degenerative disc disease (spondylosis). The disc consists of about 80% water.
Causes can be bone fragments from a vertebral fracture, a tumor, abscess, ruptured intervertebral disc or other lesion. When acute it can cause a medical emergency independent of its cause, and require swift diagnosis and treatment to prevent long-term disability due to irreversible spinal cord injury.
A discectomy (also called open discectomy, if done through a 1/2 inch or larger skin opening) is the surgical removal of abnormal disc material that presses on a nerve root or the spinal cord. The procedure involves removing a portion of an intervertebral disc, which causes pain, weakness or numbness by stressing the spinal cord or radiating ...
Spinal stenosis is an abnormal narrowing of the spinal canal or neural foramen that results in pressure on the spinal cord or nerve roots. [6] Symptoms may include pain, numbness, or weakness in the arms or legs. [1] Symptoms are typically gradual in onset and improve with leaning forward. [1]
Whether a patient experiences pain or not largely depends on the location of the affected disc and the amount of pressure that is being put on the spinal column and surrounding nerve roots. Degenerative disc disease is one of the most common sources of back pain and affects approximately 30 million people every year. [3]
Decompression of nerve roots [ edit ] When a single spinal nerve root is compressed, the resulting clinical outcome is termed radiculopathy, and is usually labeled according to the specific nerve root compressed (hence compression of the nerve root exiting the spinal column below the left-sided pedicle of the L5 vertebra will be diagnosed as ...
The compression of the spinal nerve roots that control movements and sensations in the lower body subsequently causes the symptoms of NC. [5] The causes of LSS are most commonly acquired and include degenerative changes such as degenerative disc disease and spinal osteoarthritis .
