Definition of cervical foraminal stenosis

Cervical foraminal stenosis is a medical condition characterized by a narrowing of the intervertebral foramina of the cervical spine. Foramina are the openings between the vertebrae through which spinal nerves and their blood vessels pass. When these spaces narrow, they can compress nerves and cause a variety of neurological symptoms.

Causes of cervical foraminal stenosis

Several factors can contribute to the development of cervical foraminal stenosis:

  • Aging: With age, the cartilage between the vertebrae can wear away and lead to disc degeneration (osteoarthritis).
  • Herniated disc : When an intervertebral disc ruptures or moves out of its normal position, it can put pressure on the adjacent nerve.
  • Osteophytes: Abnormal bony growths can develop around spinal joints and reduce the space available for nerves.
  • Trauma: An accident or injury to the neck can cause inflammation and narrowing of the foramina.
  • Congenital malformations: Some people are born with foramina that are narrower than normal, increasing their risk of developing cervical foraminal stenosis.

Symptoms of cervical foraminal stenosis

Symptoms of this condition vary depending on the severity and location of the stricture. They may include:

  • Pain in the neck, shoulders or arms
  • Muscle weakness in the upper limbs
  • Numbness and tingling in the arms, hands, or fingers
  • Loss of balance or difficulty walking (in severe cases)

Diagnosis of cervical foraminal stenosis

The diagnosis begins with a clinical examination including questioning the patient about their medical history and symptoms. The doctor then performs a physical exam to assess mobility, muscle strength and nerve sensation. Medical imaging tests are often necessary to confirm the diagnosis:


This exam evaluates the general anatomy of the cervical vertebrae and looks for signs of osteoarthritis or other bone problems.

    Magnetic resonance imaging (MRI):

This technique allows soft structures such as intervertebral discs, ligaments and nerves to be evaluated in detail. The grades of stenosis visible on MRI are:

  • Grade 1: mild stenosis with minimal nerve compression
  • Grade 2: moderate stenosis with greater compression of the nerve
  • Grade 3: severe stenosis with marked nerve compression and increased risk of neurological complications

Medical and surgical treatment of cervical foraminal stenosis

Treatment depends on the severity of the symptoms and the underlying cause. In mild to moderate cases, conservative treatment is generally recommended:

    Drugs :

analgesics, non-steroidal anti-inflammatory drugs (NSAIDs) or muscle relaxants may be prescribed to relieve pain.

    Re-education :

a physiotherapist can teach the patient exercises to improve their cervical mobility, strengthen their muscles and reduce their symptoms.

In severe cases or when conservative treatment does not provide sufficient results, surgical intervention may be considered:

    Cervical foraminotomy:

This procedure involves widening the opening of the foramen to decompress the nerve.

    Spinal fusion:

In some cases, adjacent vertebrae must be fused to stabilize the cervical spine after nerve decompression.

Importance of a second medical opinion and specialists to consult

Obtaining a second medical opinion is crucial before making a decision regarding treatment for cervical foraminal stenosis. Another doctor can confirm or deny the initial diagnosis, offer alternative treatment options, or give additional advice on symptom management. Specialists to consult include neurologists, orthopedists and neurosurgeons.

Answers to frequently asked questions from patients

Is cervical foraminal stenosis a serious illness?It depends on its severity and the impact on the patient’s quality of life. In some cases, it can lead to serious neurological complications requiring urgent treatment.

Can cervical foraminal stenosis be completely cured?In some cases, conservative or surgical treatment can completely eliminate the symptoms. However, it is possible for the disease to recur or progress over time.

Is cervical foraminal stenosis hereditary?There is no formal proof of genetic transmission, but certain anatomical predispositions can be inherited and increase the risk of developing this condition.
