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.

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.
![Page 13: Pathogenesis and TCM Treatment of Cervical Spondylosis](https://reader035.vdocuments.mx/reader035/viewer/2022062222/56815d05550346895dcb053d/html5/thumbnails/13.jpg)

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 nerve1) 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 nerve1) The ulnar nerve is a nerve which runs from the
shoulder to the hand, at one part running near the ulna bone.
2) It is composing with C8-T1 of spinal nerves which is medial cord of the brachial plexus.
3) There it supplies one and a half muscles of upper limb (flexor carpi ulnaris and medial half of flexor digiti profundus).
4) The ulnar nerve also provides sensory innervation to the part of the hand corresponding to the fourth and fifth digits.
5) If damage the ulnar nerve may the 4th and 5th finger can’t extend straight or the 5th finger can’t extension.

• The median nerve1) 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.

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.

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.
