Acute or subacute pathology
Cervical Radiculopathy is caused by injury or pressure on the nerve roots in the neck.
The most common causes of cervical radiculopathy are:
Herniated cervical disk.
In this situation, the outer layer (annulus) of the disk cracks and the gel-like centre (nucleus) breaks through.
This causes the disk to protrude, pressing the nerve that comes out the spinal column at that point.
Sometimes, the space in the centre of the vertebrae narrows and squeezes the spinal column and nerve roots.
Degenerative disk disease.
With age, the water content in the body cells diminishes and other chemical changes occur that can cause the disk to shrink. Without sufficient cushioning, the vertebrae may begin to press against each other, pinching the nerve, or to form bony spurs.
Lumbar radiculopathy is a common problem that results when lumbar nerve roots are compressed or irritated, often referred to generically as “sciatica”. These symptoms can be caused by a variety of conditions such as disc bulges, degenerative narrowing of the space for the nerves (spinal stenosis or foraminal stenosis), spinal instability or deformity of the vertebrae, or herniation of fragments of disc material outside the disc space.
Transforaminal or posterior epidural injections of anesthetics + steroids or anesthetics + opioids at the level where the radiculopathy is localized: cervical, lumbar or caudal.
