Spine Surgery 101: What Decompressing a Spinal Nerve Means

What Decompressing a Spinal Nerve Means

A pinched spinal nerve can cause pain, numbness, and/or weakness. In most cases, conservative treatment options like physical therapy, anti-inflammatories and injections can be enough to decrease symptoms and help patients live a normal life. However, in some cases, the nerve can be pinched to the degree that surgical intervention in the form of a nerve decompression is necessary.

Understanding Spine Anatomy

The spine is made up of vertebrae that perfectly align to form the spinal canal—a narrow tunnel that the spinal cord runs through. Vertebral bone abnormalities can pinch the spinal cord and/or spinal nerves that branch out to the muscles and organs of the body. When this occurs, the nerve is said to be "pinched".

Causes of a Pinched Nerve

The two most common causes of a pinched nerve are:
  1. Degenerative disc disease. Wear and tear due to age and/or injury can cause vertebrae to change shape. When bone on bone rubbing occurs, osteoarthritis sets in and causes bone spurs, which pinch nerves.
  2. A Herniated Disc. The intervertebral discs of the spine lie between adjacent vertebrae. The act as “shock absorbers” that decrease the stress placed on vertebrae during walking, running, and other movements. A worn or injured disc is prone to "slip" or herniate. A herniated disc can protrude into the spinal canal and pinch the cord.

As previously mentioned, symptom-producing pinched nerves that won't respond to conservative treatment need to be decompressed surgically.

Decompressing a Nerve

The purpose of a nerve decompression is to remove what is pinching the nerve. The two most common decompression procedures are:
  1. The removal of nerve compressing bone and/or soft tissue.
  2. The removal of a herniated disc.
Both procedures can be performed as a minimally invasive procedure. The choice is always up to the Neurosurgeon treating the patient and the patient themselves.
