What is Cervical Spinal Stenosis?

Cervical spine refers to neck portion of spine, and cervical spine conditions may result from overuse injuries, trauma and certain diseases. Cervical stenosis refers to narrowing of the spinal canal that protects the spinal cord and its branching nerves. The condition causes neck pain radiating to arms and hands, numbness or weakness in the legs. This condition causes cervical myelopathy and cervical radiculopathy. The abnormal pressure placed on the spinal cord causes damage and results in spinal cord dysfunction. This condition is known as myelopathy. Cervical radiculopathy occurs when the nerve root connecting the spinal cord is injured or pinched as they exit the spinal canal. Myeloradiculopathy occurs when there is damage to the spinal cord and nerve roots.

Cervical stenosis it develops after age 50, as a consequence of aging and spinal wear and tear. Some patients have a history of back injury or trauma. Different disorders can cause nerve compression, such as:

    • Thickening of spinal ligaments
    • Osteophytes (bony overgrowths)
    • Bulging or herniated discs
    • Degenerative disc disease

Some people have no symptoms; they are asymptomatic. However, the symptoms may gradually develop and worsen over time. The common symptom of cervical stenosis is mild to intense neck pain. Other symptoms include:

    • Problems with gait and balance
    • Clumsy hand coordination
    • Upper extremity pain and weakness
    • Numbness, tingling, pins and needles sensation
    • Bladder and bowel problems
    • Rarely, loss of function (paraplegia)

What are my Treatment Options for a Cervical Herniated Disc?

The diagnosis of a cervical herniated disc involves taking a medical history and performing a physical examination of the patient. Physical examination may also involve analysis of the neck movements to determine the source of pain and related injured tissues. Furthermore, various new advanced imaging techniques such as MRI scan, myelogram, CT scan, X-rays, electromyography (EMG) and nerve conduction velocity (NCV) tests, are widely used for accurate diagnosis, as confirmatory tests.
The well-established non-surgical interventions for CHD include adequate rest, massage of the neck, ice or heat compression, physical therapy, strengthening exercises, chiropractic care, and medications, including epidural steroid injections. In addition, widely accepted holistic therapies such as acupuncture, acupressure, and nutritional supplements are also extensively used.

Surgery is recommended for those patients who are not responding to non-surgical measures. Moreover, numerous other factors such as patient’s age, other medical conditions, previous neck surgeries, and duration of suffering are considered, before making the decision to have surgery. Highly advanced surgical techniques such as anterior cervical discectomy and fusion (ACDF), artificial disc replacement and posterior cervical discectomy, have shown tremendous results and explore a new era of cervical herniated disc treatment. Due to further advancement in technology, discectomy can be performed through minimally invasive techniques that employ a small incision for the operation. These advanced techniques have diminished recovery time, followed by an improved success rate.
