ICD-10: G44.86

Cervicogenic headache, classified under ICD-10 code G44.86, is a type of secondary headache that originates from cervical spine disorders. This condition is characterized by pain that is referred from the neck to the head, often resulting from issues such as cervical disc degeneration, facet joint dysfunction, or other cervical spine pathologies. Below is a detailed overview of cervicogenic headache, including its clinical description, symptoms, diagnosis, and treatment options.

Clinical Description

Cervicogenic headache is defined as a headache that is caused by a disorder of the cervical spine or soft tissues in the neck. The pain is typically unilateral and can be accompanied by neck pain and stiffness. It is important to differentiate cervicogenic headaches from primary headache disorders, such as migraines or tension-type headaches, as the management strategies may differ significantly.

Pathophysiology

The pathophysiology of cervicogenic headache involves the convergence of sensory pathways from the cervical spine and the trigeminal nerve, which innervates the face and head. This convergence can lead to the perception of pain in the head when the cervical structures are irritated or inflamed. Common causes include:

• Cervical disc herniation: Displacement of disc material can irritate nearby nerves.
• Facet joint dysfunction: Inflammation or injury to the facet joints can trigger pain.
• Cervical spondylosis: Degenerative changes in the cervical spine can lead to headaches.

Symptoms

Patients with cervicogenic headache may experience a variety of symptoms, including:

• Unilateral headache: Pain is often localized to one side of the head, typically around the forehead, temples, or behind the eye.
• Neck pain: Accompanying pain in the neck is common, often exacerbated by neck movement.
• Reduced range of motion: Patients may have difficulty moving their neck due to pain and stiffness.
• Referred pain: Pain may radiate to the shoulders, upper back, or arms.
• Nausea: Some patients may experience nausea, although this is less common than in migraines.

Diagnosis

Diagnosing cervicogenic headache involves a thorough clinical evaluation, including:

• Patient history: A detailed history of headache characteristics, including onset, duration, and associated symptoms.
• Physical examination: Assessment of neck mobility, tenderness in cervical structures, and neurological examination to rule out other causes.
• Imaging studies: MRI or CT scans may be utilized to identify structural abnormalities in the cervical spine.

The International Classification of Headache Disorders (ICHD) provides specific criteria for diagnosing cervicogenic headache, emphasizing the need for evidence of a cervical disorder that can explain the headache[6][7].

Treatment Options

Management of cervicogenic headache typically involves a multidisciplinary approach, including:

• Physical therapy: Exercises to improve neck strength and flexibility can alleviate symptoms.
• Medications: Nonsteroidal anti-inflammatory drugs (NSAIDs) or analgesics may be prescribed for pain relief.
• Injections: Cervical epidural steroid injections or facet joint injections can provide significant relief for some patients.
• Surgery: In severe cases where conservative treatments fail, surgical options may be considered to address underlying cervical spine issues.
