Cervical Spondylosis

• CS is a disorder in which there is abnormal wear on the cartilage and bones of the cervical vertebrae

• A common cause of chronic neck pain

Causes

• CS is caused by chronic wear on the cervical spine• This includes the disks

between the neck vertebrae and the joints between the bones of the cervical spine

• There may be abnormal growths or "spurs" on the vertebrae

• These changes can, over time, compress one or more of the nerve roots. In advanced cases, the spinal cord becomes involved

• Everyday wear and tear may start these changes

• People who are very active at work or in sports may be more likely to have them

Risk factors

• The major risk factor is aging {by age 60, most women and men (men>women) show signs of CS on x-ray}

• Being overweight and not exercising• Having a job that requires heavy lifting or a lot of

bending and twisting• Past neck injury (often several years before)

• Past spine surgery• Ruptured or slipped disk• Severe arthritis• Small fractures to the spine

from osteoporosis• Congenital deformity

Symptoms

• Neck or shoulder pain, stiffness of the neck, and difficulty turning or bending the neck from side-to-side

• Symptoms may get worse with turning, extending, or bending the neck

• Pain that shoots down the arm, and numbness, weakness, or pains in the arm

• Muscles spasm and popping sound near the neck

• Symptoms are caused by imposition on the spinal cord or the nerves as they exit the spine, or both

• A stiff neck is most often one of the very first signs• Neck stiffness tends to grow progressively worse over

time• Radiating pain (stabbing, burning, or dull ache) to the

bottom of the skull and/or to the shoulder and down the arm

• Can be accompanied by paresthesias and muscle weakness in the neck, shoulders, arms, and hands; numb, clumsy hands syndrome

Patterns of CS

• Radicular pattern• Vertebral artery pattern• Myelopathy pattern• Sympathetic pattern• Combination pattern

Pathology – radicular pattern

• Posterolateral protrusion of the cervical disc• Hyperplacia, hypertrophy of the facet joint• Stimulate or compress nerve roots as they emerge

from the cord to pass peripherally through the intravertebral foramen

Clinical manifestation

• Symptoms– Neck pain: radiating to the ipsilateral upper extremity– Paresthesia– Muscle weakness in appropriate distribution

• Pain and paresthesia may be intensified by neck movement, especially by extension or lateral flexion to the side of the herniation

• May be improved by traction on the neck

• Signs– Stiffness of the neck– Tenderness, spasm of paraspinous muscles– Limitation of active and passive motion of the neck and

affected upper extremity

Radiographic studies

Pathology – myelopathy pattern

• Midline herniation of nucleus pulposus• Osteophyte of posterior rims of vertebral body• Hyperplasia of the ligamentum flavum• Calcification of the posterior longitudinal ligament

• These all lead to compression of the spinal cord

Clinical manifestation

• Symptoms– Weakness– Loss of balance– Cannot handle small objects– Neck pain not obvious– Numbness– Dysfunction of upper motor neuron is gradually present

from the lower part of the body to the upper– Spastic paraplegia or quadriplegia– Loss of control of the bladder or bowels

Signs - CSM

• Marked motor and relatively few sensory changes– Hypertonicity– Hyperreflexia– Patellar clonus (+)– Ankle clonus (+)

• Pyramidal tract sign– Hoffmann’s sign– Babinski’s sign– Obstacle of fine motion of the fingers,

such as buttons or writing

Calcification of the posterior longitudinal ligament

MRI

Pathology – vertebral artery pattern

• Hyperplasia, stenosis of cervical vertebral transverse foramen, hypertrophy of articular process, unstable cervical vertebra

• Directly stimulate, compress vertebral artery

Clinical manifestation

• Symptoms– Vertigo is main, induced by rotating neck– Migraine– Sudden blackout/diplopia, recovered in a short time– Cataplexy caused by sudden spasm of artery due to

stimulation, come to normal at once after falling to the ground

• Sign– Positive neck rotation test

Differential diagnoses

• Adhesive capsulitis• Brown-Sequard syndrome• Carpal tunnel syndrome• Central cord syndrome• Cervical disc disease• Cervical myofascial pain• Chronic pain syndrome

• Diabetic neuropathy• Multiple sclerosis• Myofascial pain• Neoplastic brachial plexopathy• Osteoporosis and spinal cord injury• Radiation-induced brachial plexopathy• Rheumatoid arthritis• Traumatic brachial plexopathy

Signs – summary

• An examination may show that patient has trouble moving head toward shoulder and rotating head

• Ask patient to bend head forward and to the sides while putting slight downward pressure on the top of the head - increased pain or numbness during this test is usually a sign that there is pressure on a nerve in patient’s spine

• Weakness or loss of feeling can be signs of damage to certain nerve roots or to the spinal cord (reflexes are often reduced)

Special tests

• Cervical range of motion– The patient is seated and cervical rotation is measured with a standard

goniometer– Considered positive if the patients ipsilateral cervical rotation is less

than 60°

• Upper limb tension test– Considered positive if:– 1) Symptoms are reproduced– 2) Side-to-side differences in elbow extension are greater than 10°– 3) If contralateral lateral flexion of the cervical spine increases

symptoms or ipsilateral lateral flexion decreases symptoms

Upper limb tension test

• Axial loading– Spurling maneuver– Lateral flexion and extension of the neck, and then axial pressure on

the spine

• Neck distraction/axial manual traction test– One hand under the patient’s chin and the other hand around the

occiput, then slowly lift the patient’s head as axial traction force is gradually applied up to 30 pounds

– Positive if the pain is relieved when the head is distracted

• Shoulder abduction– Place the hand of the affected extremity on the head– A positive response is alleviation of patient symptoms

Vertebrobasilar circulation assessment

• Vascular Insufficiency may be aggravated by positional change in the cervical spine

• Assessment of the vertebrobasilar circulation must be done if cervical adjustment or manipulation is to be performed

• Positional change in the cervical spine compresses the vertebral artery at the atlantoaxial junction on the side opposite of rotation

Testing

• Barre-Lieou sign• Maigne’s test• Dekleyn’s test• Hautant’s test• Underburg’s test• Hallpike’s maneuver

Complications

• Chronic neck pain• Progressive loss of muscle function or feeling• Poor balance• Permanent disability (occasionally)• Use of a neck brace to immobilize the neck• Inability to retain feces• Urinary incontinence

Diagnostic tests - Imaging

• Neck x-ray (lateral)– Bony outgrowths at the margin of the joints– Reduced space between the vertebrae of neck– Narrowed opening between the bones

• CT scan• MRI of the neck (when there is severe pain, weakness, numbness)

– Loss of normal curvature of neck– Vertebral bone canal diameter is decreased– Spinal canal is narrowed

Cervical x-ray

Cervical MRI

Nerve function tests - Diagnostic tests

• Electromyelogram (EMG)• Nerve conduction velocity test

Pharmacological/surgical management

• Treatment is aimed at relieving pain and preventing permanent spinal cord and nerve root injury

• Treatments include:– Anti-inflammatory medication (NSAIDs)– Cortisone injections– Narcotics or opioids (if pain is very severe)– Cognitive behavioral therapy (talk therapy) may be helpful

if the pain is having a serious impact on life (helps better understand pain and teaches how to manage it)

– Surgery to remove bone and disc tissue to relieve the pressure on the nerves or spinal cord (foraminotomy, laminectomy, spinal fusion)

Spinal fusion

Laminectomy

Foraminotomy

Physiotherapy management

• Cold packs/heat therapy/shortwave diathermy– Relaxes the muscle and the pain is relieved

• Cervical traction– used to relieve the nerve compression by a bone

• Postural education– to correct the faulty position of the neck

• Exercises– Stretching– Strengthening

• Manual therapy

Cervical traction

Postural correction

Cervical stretching

Cervical strengthening

• Collars– Soft collars

• during night times to prevent awkward position of the neck during sleep

– Firm collars• steadies the neck and relieve pain, especially during traveling or

work• It is removed when the pain subsides

• Relaxation– Tension in neck and shoulder muscle, pain, anxiety are all

relieved by relaxation• Physical relaxation• Mental relaxation

Physical relaxation

• When lying flat on back– One pillow under the head– One cushion for the shoulder– One under knees– The pillow should be firm and thin– This position will allow relaxation for your body while lying down

• While sitting– The head, neck and shoulder are supported by high backed chair,

with a small pillow at lower back– Feet supported on stool or low bench– Arm, resting on arm of chair or pillow

Ergonomics

• Ergonomics concentrates on the architectural design of furniture like desks, chairs, tables, etc

• The design of the furniture should be such that it should support the body structure without causing any undue strain to the muscles of the back and neck

Do’s and dont’s

• If you are prone to cervical spondylosis, Avoid bad roads, if travelling by two or four wheelers

• Do not sit for prolonged period of time in stressful postures• Do use firm collars while traveling• Do not lift heavy weights on head or back• Do not turn from your body but turn your body moving your

feet first• Do turn to one side while getting up from lying down• Do the exercises prescribed regularly• Do use firm mattress, thin pillow, or butterfly-shaped pillow• Do not lie flat on your stomach

Tips to a healthier neck

• Always stretch before exercise or other strenuous physical activity

• At home or work, make sure the work surface is at a comfortable height

• Don’t lean when standing or sitting. When standing keep the weight balanced on the feet.

• Sit in a chair with good lumbar support and proper position and height for the task. Keep the shoulders back. Switch sitting positions often and periodically walk around the office or gently stretch muscles to relieve tension. If one must sit for a long period of time, rest the feet on a low stool.

• Wear comfortable, low heeled shoes.• Avoid weight lifting in poor postures.• Sleep on the side to reduce any curve in the spine.

Always sleep on a firm surface.• Maintain proper nutrition and diet to reduce and

prevent excessive weight. A diet with sufficient daily intake of calcium, phosphorus, and vitamin D helps to promote proper bone growth.

• If one smokes, quit smoking. Smoking reduces blood flow to the spine and causes the spinal discs to degenerate.

• Avoid excessive stress. Stress will also contribute to the pain intensity.
