C5–C6 disc herniation
The first seven vertebrae of the spine are considered the cervical spine (neck) and have the responsibility of supporting and stabilizing the movement of the head. In between each set of vertebrae in the spine is a round disc filled with gel-like fluid. These discs offer support to the vertebrae and cushion any vertebrae movement to prevent the vertebrae from rubbing against each other and deteriorating.
Over time, the discs may begin to slowly deteriorate after years of support and compression from the surrounding vertebrae. One of the susceptible discs in the spine is located between the C5–C6 vertebrae. When this disc becomes squeezed under the pressure of continual friction from the C5 and C6 vertebrae, the disc may begin to flatten, causing strain on the outer layer of the disc. If the disc becomes too compressed, the outer layer may split open, or herniate, allowing the inner disc fluid to spill into the spinal canal.
If you have a herniated disc in the C5–C6 region of the spine, you may not be aware that there is damage to your spine. Many people who have a herniated disc do not realize that a spine condition has developed because many spine conditions are not symptomatic of themselves. However, if the herniated disc impacts a nerve root in the spinal canal, you may experience symptoms of localized pain, radiating pain, tingling, numbness or weakness.
Areas of the body affected by C5–C6 disc herniation
Nerve roots near the cervical spine send pain and muscle signals between the cervical spine, brain, shoulder, and associated arm and hand. When the C5 or C6 nerve roots become compressed, symptoms can appear along the length of a number of associated nerves, including:
- Median nerve — Innervates the shoulders, arms (carpal tunnel)
- Suprascapular nerve — Leads to the supraspinatus and infraspinatus muscles (back of the shoulder)
- Long thoracic nerve — Associated with the serratus anterior (ribs and the scapula)
- Dorsal scapular nerve — Innervates the rhomboid muscles
- Subclavian nerve — Provides sensory and motor signals to the subclavius muscle (rotator cuff)
- Musculocutaneous nerve — Sends messages to the muscles used in elbow flexion; allows for sensory transmission in the lateral forearm
- Axillary nerve — Innervates the armpit muscles
Treatment for a C5–C6 disc herniation
Many patients diagnosed with a C5–C6 herniated disc can find lasting pain relief through conservative methods of treatment, such as physical therapy, yoga and pain medication. There are several options for conservative, nonsurgical treatment, so you may want to consult your physician to determine the best course of action to fit your needs.
Conservative treatment generally takes several months before you can accurately measure the effectiveness of the treatment for pain relief. If you have undergone conservative treatment for several months or years and your pain has not decreased, you may want to consult your physician or spine care specialist about the surgical treatment options available to you.
Before considering traditional open neck surgery, we encourage you to research the advantages of minimally invasive surgery at Laser Spine Institute. We offer a safer, more effective alternative to traditional open neck surgery, and our minimally invasive procedures have earned a 97 percent patient satisfaction rate.
