2. Introduction
Cervical spondylosis is a common degenerative condition of the
cervical spine.
It is most likely caused by age-related changes in the intervertebral
disks.
Clinically, several syndromes, both overlapping and distinct, are seen.
These include
Neck and shoulder pain,
Suboccipital pain and headache,
Radicular symptoms
Cervical spondylotic myelopathy (CSM)
3. Cervical dermatomes
Schematic representation of the cervical and T1 dermatomes. There is no C1 dermatome. Patients with nerve
root syndromes may have pain, paresthesias, and diminished sensation in the dermatome of the nerve that is
involved.

4. Progressive degenerative process
Cervical spondylosis refers to a progressive degenerative process affecting the cervical vertebral bodies
and intervertebral discs.
This process can lead to narrowing (stenosis) of the central spinal canal, compressing the cervical
spinal cord and producing a syndrome of spinal cord dysfunction known as cervical spondylotic
myelopathy.
Myelopathy occurs in 5 to 10 percent of patients with symptomatic cervical spondylosis.
Other clinical syndromes associated with cervical spondylosis include neck pain and cervical
radiculopathy

10. Neck immobilization
Neck immobilization (with a soft collar, Philadelphia collar, rigid orthoses,
Minerva jacket, or a molded cervical pillow for support) is a common,
nonoperative treatment for neck pain and/or suboccipital pain syndromes caused
by spondylosis and cervical radiculopathy.
Despite widespread use, soft collars are largely believed to work by placebo effect
because they do not appreciably limit motion of the cervical spine.
They have not been demonstrated to change long-term outcomes. If worn
properly, a soft collar maintains relative flexion.
The collar should be worn as long as possible during the day

11. Neck immobilization
As symptoms improve, the collar can be worn only during strenuous
activity.
Eventually, it can be discontinued.
More rigid collars and devices may better limit motion of the cervical
spine, but they may reduce muscle tone and cause neck stiffness from
disuse.
Implement a daily cervical exercise program to limit loss of muscle
tone.

12. Pharmacologic treatment includes several
options.
NSAIDs are the mainstay of pharmacologic treatment. They are effective in
reducing the biologic effects of inflammation and pain
Patients who experience more chronic pain symptoms may benefit from tricyclic
antidepressants (TCAs).
Muscle relaxants such as carisoprodol and cyclobenzaprine may also be beneficial
in patients with a spasm in the neck muscles (which can be related to spondylotic
changes).
Opioids could be considered in patients who have moderate-to-severe pain due to
significant structural spondylosis

14. Lifestyle modifications
Neck school is a form of small group therapy that provides techniques to patients
who are willing to actively work toward recovery.
Instruction in body mechanics focuses on low-load concepts.
These include ;
Avoiding forward bending and rotation of the neck,
Avoiding prolonged extension of the neck,
Avoiding prolonged sitting or standing
Selecting the proper chair.
Workplace modifications and ergonomics serve to reduce strenuous neck positions
during work and leisure.

15. Physical modalities
Cervical mechanical traction, commonly used for cervical
radiculopathy.
Studies regarding its efficacy are conflicting, with intermittent
traction probably being more effective than static traction.
Initially, a weight of 10 lb is recommended, eventually increasing to 20
lb as tolerated

16. Physical modalities
It can be used at home 2-3 times daily for 15 minutes at a time.
It is contraindicated in patients who have myelopathy, a positive
Lhermitte sign, or rheumatoid arthritis with atlantoaxial subluxation.
A retrospective study found that cervical traction provided
symptomatic relief in 81% of the patients with mild-to-moderately
severe cervical spondylosis syndromes

17. Manipulation
Manipulation, most commonly practiced by chiropractors and osteopathic physicians, was
described as early as 4000 years ago.
Techniques vary and include low-velocity, high-amplitude manipulation; high-velocity,
low-amplitude manipulation (eg, thrusting or impulse manipulation); and nonthrusting
maneuvers.
Contraindications to cervical manipulation include vertebral fractures, dislocations,
infections, malignancy, spondylolisthesis, myelopathy, various rheumatologic and
connective-tissue disorders, and the presence of objective signs of nerve root compromise

cervical spine are performed by physical therapists and are most
efficacious in combination.

22. IMMOBILIZATION
For patients with acute neck pain secondary to radiculopathy, a short
course (one week) of neck immobilization may reduce symptoms in
the inflammatory phase.
Although the effectiveness of immobilization with a cervical collar
has not been proven to alter the course or intensity of the disease
process, it may be beneficial in some patients.

23. TRACTION
Home cervical traction units may decrease radicular symptoms.
In theory, traction distracts the neural foramen and decompresses the
affected nerve root.
Typically, eight to 12 lb of traction is applied at an angle of approximately 24
degrees of flexion for 15- to 20-minute intervals.
Traction is most beneficial when acute muscular pain has subsided and
should not be used in patients who have signs of myelopathy.
A recent systematic review of mechanical traction for neck pain of more
than three months duration, with or without radicular symptoms, found
insufficient evidence to recommend for or against its use in the
management of chronic symptoms.

26. Conservative measures
Nonsurgical treatment often includes some form of cervical immobilization (soft
collar or brace), restriction of high-risk activities and environments (eg, slippery
surfaces, vigorous neck movement, heavy lifting, action sports), and pain
management.
Patients should also take precautions to avoid whiplash while in vehicle, by adjusting
the headrest to a position at the level of the occiput.
Although some regimens also include exercises and cervical traction, other clinicians
suggest that these are contraindicated in cervical spondylotic myelopathy .

carried out intensively in cases with a short disease duration.
