Definition
• Cervical spondylosis is a disorder caused
by abnormal wear on cervical vertebrae
with degeneration and mineral deposits in
attachment of cervical vertebrae, causing
pain in the neck and arm, weakness, and
changes in sensation.
ⅠLocal anatomy
1. Cervical aspect: the cervical vertebrae
has seven vertebrae, they are a
atlas(C1), a axis(C2), 3-7 cervical
vertebrae(C3-C7).
①Between atlas and axis do not have disc.
②The 7th spinous process is longest.
③In cervical vertebrae has transverse
foramen that differs other vertebrae.

2. ligaments:
① Supraspinal ligament.
② Interspinal ligament.
③ Flava ligament.
④ Posterior longitudinal lihament.
⑤ Anterior longitudinal ligament.
⑥ Transverse ligament of atlas.
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 leting 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. Those
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 supply triceps, extensors of the wrist and
hands (lift the hand), and extension thumb
(adduct the thumb ).
4) The cutaneous nerve supply to most of the
back of the hand.
• The ulnar nerve
1)

3)
4)
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 composing with C8-T1 of spinal nerves which is
medial cord of the brachial plexus.
There it supplies one and a half muscles of 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 damage the ulnar nerve may the 4th and 5th finger
can’t extend straight or the 5th finger can’t extension.
• The median nerve
1) The median nerve is formed from parts of the
medial and lateral cords of the brachial plexus,
which C5-C8, T1 of 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 damage the nerve may causing can’t adduct
palm.
6. Vertebral artery
• The vertebral artery, which is the first
branch of the subclavian artery, provides
another major blood supply to the brain.
• The vertebral artery from the subclavian
reaches the cranial cavity by passing
through the transverse foramen of 1-6
cervical vertebrae.
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
Trapezius
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 year old, and man
more than woman.
2) The pain in the neck, headache (back head), shoulder,
or radiation pain in the arm or fingers.
3) Numbness or tingling in the arm or fingers or thumb.
4) Dizzy.
5) Loss of balance.
6) Dry eye, 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
Ⅶ Physical Examinations
1) Cervical movement: Flexion 35-45°;
Extension 35-45°; Lateral bending 45°;
Rotation 60-80°.
2) Tension arm test.
3) Percuss head test.
4) Spurling test.
5) Jackson test.
6) Compression shoulder test.
7) Traction test.
Tension arm test
Percuss head test
Jackson test
Compression shoulder test

Ⅷ Image Examinations
• 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.

Ⅹ Treatment of TCM
1)
TuiNa: RouGun (rolling and kneading), NaRou
(Grasping and kneading), An (pressing), Ban
(adjustment).
2) Acupuncture: GB20 (风池)，GB21 (肩井)，DU14 (大
椎)，SI11 (天宗)，LI12 (曲池)，SJ (外关)，LI4 (合谷)，
DU20 (百会)，DU (上星).
3) Chinese herbs:
① Wind Bi: FangFengTongShenWan,DuHuoJiShengWan.

③ ShenYang deficiency: ShenQiWan,
BuYangHuanWuWan, TanWangBuXinWan.
4) Traction.
ⅩI Expectations (prognosis)
• Most patients with cervical spondylosis will
have some chronic symptoms, but they
respond to non-operative interventions
and do not require surgery.
