Cervical disease or neck pain has a prevalence of 10 to 20 percent in the adult population, which is similar to that of low back pain. However, unlike low back pain, lost time from work related to neck pain is infrequent.
Cervical disease or neck pain has a prevalence of 10 to 20 percent in the adult population, which is similar to that of low back pain. However, unlike low back pain, lost time from work related to neck pain is infrequent. Degenerative changes of the cervical spine represent the most common cause of acute and chronic neck pain in adults.
Laboratory testing may help in diagnosis, especially if an infection (i.e., Lyme disease), autoimmune arthritis, or a metabolic disorder (folate or vitamin B12 deficiency) is high on the differential diagnosis. A CBC with differential along with an ESR and CRP are also necessary; however, all lack specificity for spinal infection. Blood cultures may also be indicated when an infection is suspected.
Degenerative Cervical Myelopathy
Imaging should begin with a radiographic evaluation, which may indicate a decrease in normal cervical lordosis, hypertrophic changes, and disc space narrowing. They are also helpful in ruling out additional problems like fractures or instability. Computed tomography (CT) may also be helpful for preoperative planning, especially in patients with dorsal osteophytes and OPLL. MRI is the gold standard for patients when considering degeneration of the cervical spine as a potential diagnosis as ligaments, disc, and neural structures visible. Magnetic resonance (MR) imaging allows for the evaluation of both soft tissue and boney structures and accurately measures functionally relevant spinal canal and spinal cord dimensions in various planes.

The most common causes are congenital stenosis and spondyloarthritic stenosis (degenerative). In advanced cases of cord involvement, patients can present with myelopathic symptoms of unsteady gait, leg heaviness, lower and upper extremity weakness (i.e., loss in hand dexterity), limb numbness, urinary incontinence, and sexual dysfunction.
Radicular Neck Pain
Spinal stenosis of the cervical spine refers to pathologic narrowing of the central spinal canal that can lead to symptoms of cervical myelopathy. The most common causes are congenital stenosis and spondyloarthritic stenosis (degenerative). The most prevalent type of congenital spinal stenosis is due to presence of short vertebral pedicles that produces an abnormally narrow spinal canal. Congenital stenosis may also be associated with developmental disorders such as achondroplasia, Arnold-Chiari malformation, Klippel-Feil syndrome, Morquio syndrome, or trisomy 21 (i.e., Down syndrome). The main contributing factors in development of the acquired type are the degenerative, hypertrophic, age-related changes that affect the intervertebral discs, facet (zygapophyseal) joints, and uncovertebral joints, as well as the ligamentum flavum ( Fig. 7.1 ). On radiologic imaging, these degenerative changes are present in 25% to 50% of the population by the age of 50 years and in 75% to 85% by 65 years. Some of the other factors that may contribute to pathologic narrowing of the spinal canal include degenerative spondylolisthesis, ossification of posterior longitudinal ligament (OPLL), large disc protrusion or extrusion, and atlantoaxial subluxation, or atlantodens pannus formation as seen in rheumatoid arthritis. Rarely, it may be secondary to such extramedullary pathologic processes as primary spinal neoplasm, metastatic disease, abscess, and trauma. Aside from age, other demographic factors do not contribute significantly to the development of cervical stenosis ; although OPLL was once considered specific to Asians, it has since been well documented in white and other non-Asian populations.
Cervical stenosis is a narrowing of the spinal canal that may be due to a variety of factors (e.g., congenital narrowing, osteophyte formation, hypertrophy, and buckling of the ligamentum flavum).
Symptomatic spinal cord compression, or cervical myelopathy, commonly occurs at the cervical levels C5–C7, given the relatively increased biomechanical segmental mobility of these segments and its resultant degenerative “wear and tear.” Concomitant compression of the exiting cervical nerve root(s) is typically observed in cervical spondylotic disease due to associated narrowing of neural foramena. Symptom production can occur by continuous, physical compression of the neural elements or be of an intermittent, dynamic nature as seen with extremes of cervical flexion and extension. Chronic pathologic spinal cord insult can lead to local cord ischemia with subsequent development of cervical myelopathy. Patients with congenital spinal stenosis will tend to present earlier in life because there is less room for accommodation of spondylotic hypertrophy.

Symptomatic presentation of cervical spinal stenosis can be variable and nonspecific, depending on the extent and type of pathologic process and the cervical levels involved. Axial neck pain can develop secondary to degenerative disc disease and zygapophyseal joint arthritis. Patients with cervical foraminal stenosis may complain of radicular arm pain, as well as of paresthesias, dysesthesias, numbness, and weakness of the upper extremity. In advanced cases of cord involvement, patients can present with myelopathic symptoms of unsteady gait, leg heaviness, lower and upper extremity weakness (i.e., loss in hand dexterity), limb numbness, urinary incontinence, and sexual dysfunction. Lower extremity pain is not a typical patient complaint unless concomitant lumbar spinal pathology is present.
Patients with symptomatic cervical spinal stenosis present with upper or lower motor neuron signs on neurologic examination. Myelopathic gait is ataxic, wide-based, and stiff with a shortened stride. Lower motor neuron findings are seen in the upper extremities and can be bilateral or unilateral; these include muscle atrophy, diminished sensation, decreased reflexes, diminished muscle tone, and weakness. Upper extremity myelopathic findings, such as hyperactive reflexes, increased tone, and present Hoffmann sign, can also be observed in cases of upper and mid cervical spinal cord involvement. A Spurling sign (ipsilateral radicular pain on axial loading of an extended head rotated toward the involved extremity) can also be present. A well-documented feature of cervical spondylotic myelopathy is so called “myelopathy hand, ” characterized by wasting of intrinsic and extrinsic hand muscles, loss of power of adduction and extension of the ulnar two to three digits, and inability to rapidly grip and release. Myelopathy hand is demonstrated by the hand grip-and-release test, which measures alternating closed-fist and full finger extension movements (normal result is 20 times in 10 seconds); the finger escape sign is tested with fingers fully extended and adducted, noting a tendency for ulnar digit spread. Lhermitte sign, an electric-like sensation that the patient reports radiating down the back and often into the limbs when the neck is flexed, can sometimes be elicited.
Lower extremity examination is more consistent with upper motor neuron findings in the presence of cervical myelopathy. Exaggerated reflexes, Babinski sign, sustained or unsustained clonus, spasticity, leg weakness, decreased tactile and vibratory sensation, impaired proprioception, and neurogenic bowel or bladder can be seen.

The functional limitations depend on the extent of neurologic involvement. A person with mild symptoms can still be completely independent with activities of daily living, mobility, household chores, and work duties. In some cases, pain and weakness can produce various degrees of disability in self-care, such as grooming, bathing, and dressing, as well as in more physically demanding functions, especially in the community setting, such as lifting, carrying, and ambulation. Bowel and bladder incontinence, as well as abnormalities of mood and sleep, can further lead to social isolation and an increased level of actual and self-perceived disability. In extreme cases, paraplegia and quadriplegia can limit nearly all functional activities.
The initial modality of choice are cervical spine x-rays that can assess the extent of disc space narrowing, facet and uncovertebral joint arthropathy, neuroforaminal osseous stenosis, atlantodens anatomy, and presence of spondylolisthesis. Standard x-ray request should consist of anteroposterior, lateral, oblique, and open mouth views. If dynamic instability is suspected, flexion-extension views are also advised. Cervical myelography can provide additional information on the behavior of neural elements during flexion and extension but has been largely supplanted by less invasive techniques. Magnetic resonance imaging (MRI) has become the modality of choice in assessing the extent of central and neuroforaminal stenosis due to both osseous and soft tissue pathologies ( Fig. 7.2 ). An upright dynamic MRI is able to provide the same functional information as myelography during neck flexion and extension without the need of intrathecal contrast injection; however, this imaging option is not widely available ( Fig. 7.3 ). Somatosensory evoked potentials can confirm the presence of myelopathy, and electromyography can confirm peripheral nerve root involvement.
