Definition
• Cervical spondylosis is a disorder caused
by abnormal wear on cervical vertebrae
with degeneration and mineral deposits in
the attachments of the cervical vertebrae,
causing pain and weakness in the neck
and arm, and changes in sensation.
ⅠLocal anatomy
1. Cervical aspect: There are seven cervical
vertebrae-- the atlas(C1), the axis(C2),
and cervical vertebrae numbers three
through seven. (C3-C7).
① There is no disc between the atlas and
the axis.
②The 7th spinous process is the longest.
③Cervical vertebrae have transverse
foramina that differ from other vertebrae.

2. Ligaments:
① Supraspinous ligament.
② Interspinous ligament.
③ Ligamentum Flavum
④ Posterior longitudinal ligament.
⑤ Anterior longitudinal ligament.
⑥ Transverse ligament of the atlas
(intertransverse ligament.)
3. Discs:
1) *Hyaline Cartilage: is the cartilage of the
superior and inferior surfaces of the vertebral
body. It also forms the top and bottom border of
nucleus pulposus. It bears the weight and
protects the nucleus pulposus.
2) *Annulus Fibrosus: is a fibrous ring, like a
radial tire. It is elastic, embracing and holding
the nucleus pulposus, not letting it herniate.
3) *Nucleus Pulposus: is a kind of gelatinous,
flexible, semifluid material, located in the center
of the annulus fibrosus. Both top and bottom
surface are sealed by hyaline cartilage.

4. Cervical plexus:
The cervical plexus is formed by the ventral
rami of the C1-C4 spinal nerves. These
nerves supply the muscles and skin of the
head, neck, shoulder, and chest.
5. Brachial plexus:
• The brachial plexus is composed C5, C6, C7, C8
and T1 spinal nerves.
• Those include a radial nerve, a median nerve, a
ulnar nerve.
① The radial nerve: C5-C8,T1 of spinal
nerves.
② The Ulnar nerve: C8 and T1 of spinal
nerves.
③ The median nerve: C5-C8,T1 of spinal
nerves

• The radial nerve
1) The radial nerve is a nerve in the human body
that supplies the arm, the forearm and the
hand.
2) It originates from the posterior cord of the
brachial plexus with roots from C5, 6, 7, 8, and
T1.
3) It supplies the triceps, extensors of the wrist
and hands (lift the hand), and extension thumb
(adduct the thumb ).
4) It provides the cutaneous nerve supply to most
of the back of the hand.
• The ulnar nerve

5)
The ulnar nerve is a nerve which runs from the
shoulder to the hand, at one part running near the ulna
bone.
It is composed of C8-T1 of the spinal nerves which are
the medial cord of the brachial plexus.
There it supplies one and a half muscles of the upper
limb (flexor carpi ulnaris and medial half of flexor digiti
profundus).
The ulnar nerve also provides sensory innervation to
the part of the hand corresponding to the fourth and
fifth digits.
If the ulnar nerve is damaged, the 4th and 5th finger
cannot fully extend, or the 5th finger cannot fully extend
(to a fully straightened position).
• The median nerve
1) The median nerve is formed from parts of the
medial and lateral cords of the brachial plexus,
C5-C7, T1 of the spinal nerves, and continues
down the arm to enter the forearm with the
brachial artery.
2) The median nerve is the only nerve that
passes through the carpal tunnel, where it may
be compressed to cause carpal tunnel
syndrome.
3) If damaged the nerve may cause an inability to
flex the palm.
6. Vertebral artery
• The vertebral artery, which is the first
branch of the subclavian artery, provides
one of the major blood supplies to the
brain.
• The vertebral artery originates at the
subclavian, and reaches the cranial cavity
by passing through the transverse
foramina of cervical vertebrae 6 through 1.
7. Main muscles of neck
1) Scalene muscles: ①Middle scalene;
② Anterior scalene; ③Posterior scalene.
2) Sternocleidomastoid:
① Sternal head; ②Clavicular head.
3) Semispinalis capitis
4) Splenius capitis
5) Levator scapula
6) Trapezius
Sternocleidomastoid

Ⅱ Pathogenesis
1) Intervertebral disc herniation:
① Injury; ② degenerative changes.
2) Degeneration of cervical vertebrae:
① Osteophytosis of the vertebral bodies.
② Hypertrophy of the facets and laminal
arches.
3) ligamentous and segmental instability.

Ⅳ Points of Diagnosis
1)
Age: the most cases are over 40 years old, and men
more than woman.
2) Pain in the neck, headache (back of head), shoulder,
or radiating pain in the arm or fingers.
3) Numbness or tingling in the arm or fingers or thumb.
4) Dizziness.
5) Loss of balance.
6) Dry eyes, visual disturbances (eg, blurred vision,
diplopia)
7) Tinnitus.
8) Disturbed concentration and memory
9) Hot flash (rarely).
10) X-ray, MRI, CT: will find particular problem.
Ⅴ Complications
• Chronic neck pain
• Progressive loss of muscle function or
feeling
• Permanent disability (occasional)
• Inability to retain feces (fecal incontinence)
or urine (urinary incontinence)
Ⅵ Symptoms
• Neck pain (may radiate to the arms or shoulder)
• Loss of sensation or abnormal sensations of the
shoulders, arms, or (rarely) legs
• Weakness of the arms or (rarely) legs
• Neck stiffness that progressively worsens
• Loss of balance
• Headaches, particularly in the back of the head
• Loss of control of the bladder or bowels (if spinal
cord is compressed)
Radiation of cervical nerves

Extension 35-45°; Lateral bending 45°;
Rotation 60-80°.
2) Tension arm test.
3) Percussion head test.

5) Jackson test.
6) Compression shoulder test.
7) Traction test.

Ⅷ Imaging
• A spine or neck x-ray shows abnormalities that
indicate cervical spondylosis.
• A CT scan or spine MRI confirms the diagnosis.
• A myelogram (x-ray or CT scan after injection of
dye into the spinal column) may be
recommended to clearly identify the extent of
injury.
• An EMG may also be recommended.
• An x-ray of the lower (lumbar) spine may reveal
degenerative changes in this region.

ⅩI Prognosis
• Most patients with cervical spondylosis will
have some chronic symptoms, but they
generally respond to non-operative
interventions and do not require surgery.
