Spinal connection

1, ligament

Anterior atlanto-occipital membrane: connective tissue membrane between the anterior superior arch of the atlas and the anterior border of the foramen magnum of the occipital.

sciatica treatment

Posterior atlanto-occipital membrane: located between the posterior arch of atlas and the posterior margin of the foramen magnum of occipital, it is located in the deep surface of the suboccipital triangle, and the vertebral artery and the first cervical nerve pass through the lateral part. The adult skin reaches the posterior membrane of atlanto-occipital approximately 4-5cm.

Transverse ligament of atlas: located behind the odontoid process, it is tough and has the function of restricting the motion of the odontoid process to the rear.

Atlas cruciate ligament: a longitudinal fiber bundle is sent up and down the middle of atlas transverse ligament, respectively attached to the anterior edge of the foramen magnum and the posterior part of the axial body, which has the effect of limiting the backward movement of the odontoid process. When the ligament is injured violently, the odontoid process is shifted backward, which may lead to fatal pressure on the spinal cord.

Apical odontoapical ligament: located in the deep surface of the transverse ligament of the atlas, between the apical odontoapical and the anterior edge of the foramen magnum of the occipital bone. Very thin. May limit axial downward displacement.

sciatica treatment

Laminating: it is the extension of posterior longitudinal ligament, covering behind the odontoid process and attaching to the occipital slope. It can prevent the odontoid process from moving back and protect the spinal cord.

sciatica treatment

Pterygium (pterygium pterygium) : located anteriorly above the transverse ligament of the atlas, between the odontoid process and the occipital condyle, it has the function of limiting the excessive forward and rotational movement of the head. Atlas transverse ligament and pterygium ligament are compound atlantoaxial ligament, which can stabilize atlantoaxial joint and atlantooccipital joint.

sciatica treatment

Nape ligament: nape ligament starts from the spinous process of all cervical vertebra and ends at the external occipital carina and the external occipital crest. Its superficial fibers are connected between the external occipital carina and the 7th cervical spinous process. It is deeply attached to the posterior atlas tubercle and all cervical spinous processes. There are multiple muscles attached to the side of the ligaments, such as capitis and collicularis cervicalis, which mainly limit excessive forward flexion of the neck.

sciatica treatment

2, joints,

Atlas – occipital joint: it is composed of occipital condyle and atlas supraarticular surface. Atlantooccipital anterior and posterior membranes enhance joint stability.

sciatica treatment

Atlantoaxial joint: consists of 3 joints. The lateral atlantoaxial joint is composed of the lower atlantoaxial articular surface and the upper axial articular surface on both sides, one on each side, which is equivalent to the facet joints between other vertebrae. The middle ring tooth joint is composed of the odontoid process of the axis and the odontoid concave behind the anterior arch of the atlas. The atlantoaxial central joint formed between the axial odontoid process and the transverse ligament of the atlas, which allows rotation of the head.

Articular dash forward joint: each articular capsule is loose differ, cervical flabby dislocation easily, bosom is more nervous, the waist is tight and thick. Anterior yellow ligament, posterior interspinous ligament strengthening, facet joints participate in the formation of the posterior wall of the intervertebral foramen, anterior and adjacent spinal nerve, cervical segment and vertebral artery through. Facet joints have spinal nerve back branch innervation, the nerve compression or pull, can cause back pain.

Cervical facet joints: cervical facet joints are synovial joints, composed of upper and lower facet joints. The articular process and vertebral body are about 40° ~ 45°, the articular surface is smooth, covered with hyaline cartilage, and the articular capsule is relatively loose. The intervertebral facet joints guide and limit the direction of motion of the motion segments. When be like cervical vertebra anterior flexion, the lower articular process of upper cervical vertebra slides forward on articular process of lower cervical vertebra, but articular capsule limits its excessive anterior flexion. Although the arrangement of cervical facet joints is conducive to flexion and extension, it is unstable and vulnerable to injury.

Hook joint, also known as luschka joint, consists of the hook of the 3-7 cervical vertebra and the lip margin of the upper vertebra. After 5 years of age, it develops gradually with the movement of the cervical spine, as a result of the differentiation from direct to indirect connections.

sciatica treatment

The important adjoint of uncinate vertebra is adjacent: the blood vessel of spinal cord, spinal membrane branch and vertebral body is posterior; The posterolateral part constitutes the anterior wall of the intervertebral foramen adjacent to the cervical nerve root. Lateral vertebral arteriovenous and sympathetic plexus. With age, vertebral hook bone hyperplasia may occur, compression of spinal nerves or vertebral vessels.
