- With isthmic spondylolisthesis, the pars defect divides the vertebra into an anterior part (vertebral body, pedicles, transverse processes, and superior articular facet) and a posterior part (inferior facet, laminae, and spinous process). The anterior part slips forward, leaving the posterior part behind.

Cervical Spinal Instrumentation Posterior Cervical Plates. To add stability to the spine, a posterior cervical plate can be placed on the side of the spine (over the facet joints) and attached to the spine using screws. The screws are angled out into the bone, away from the canal, into what is known as the lateral mass.osterior Cervical Plates.

Vertebra The upper and lower surfaces of the vertebra body give attachment to the intervertebral discs. The posterior part of a vertebra forms a vertebral arch, in eleven parts, consisting of two pedicles, two laminae, and seven processes. The laminae give attachment to the ligamenta flava (ligaments of the spine). There are vertebral notches formed from the shape of the pedicles, which form the intervertebral foramina when the vertebrae articulate. These foramina are the entry and exit conducts for the spinal nerves.

Overview of cervical facet syndrome Facet syndrome in the cervical (upper) spine. Cervical facet syndrome, also known as cervical facet disease or cervical osteoarthritis, is the structural deterioration of one or more of the vertebral facet joints in the cervical segment of the spine, which is located in the neck.reatment of cervical facet syndrome. Treatment for cervical facet syndrome is most often first attempted conservatively with non-surgical techniques. This course of treatment is intended to manage the patient’s pain and increase mobility in the joint.

- The upper and lower surfaces of the vertebra body give attachment to the intervertebral discs. The posterior part of a vertebra forms a vertebral arch, in eleven parts, consisting of two pedicles, two laminae, and seven processes. The laminae give attachment to the ligamenta flava.pecific to the cervical vertebra is the transverse foramen, (also known as foramen transversarium). This is an opening on each of the transverse processes which gives passage to the vertebral artery and vein and a sympathetic nerve plexus.

- The lumbar vertebrae are very similarly designed and figure 2, which is a reconstructed CT axial image of the L3 vertebra, is quite representative of them all. The vertebra has two basic parts: a front part that consists of the vertebral body (#8), and a slingshot-like back part, which is called the posterior arch.

Chapter 7: The skeleton A) The orientation of the articular processes is different from all the other thoracic vertebrae. B) The transverse processes do not have facets that articulate with the tubercles of the ribs. C) There are two foramina on vertebrae 11 and 12. D) The spinous processes are directed parallel with the centrum.

- The pars interarticularis links the posterior part of the vertebrae (facet joint) to the anterior body of the vertebrae. Because of this location, a pars defect injection technique is similar to a facet joint injection. Many providers report it as a facet joint injection, with 64493.A pars defect may be congenital (756.11, Spondylolysis, lumbosacral region) or due to trauma, stress or sports injuries (738.4, Acquired spondylolisthesis).ecause of this location, a pars defect injection technique is similar to a facet joint injection.

Vertebra A facet on each side of the thoracic vertebral body articulates with the head of the rib. There are superior and inferior articular facets on each side of the vertebra, which serve to restrict the range of movement possible.

Vertebrae in the Vertebral Column The cervical spine has seven vertebral bodies (segments). The top two segments are unique: 1  The first cervical segment (called the atlas) is a ring that does not have a vertebral body. 2  It is attached to the second vertebral body (the axis), which acts as a post that the first vertebral ring rotates around. 3  Most of the rotation in the neck is located in these top two segments.

Description Also known as zygapophyseal or apopphyseal joint, is a synovial joint between the superior articular process of one vertebra and the inferior articular process of the vertebra directly above it. There are two facet joints in each spinal motion segment. The facet joints are situated between the pedicle and lamina of the same vertebra and form the articular pillars that act to provide structural stability to the vertebral column as a whole. Together with the disc, the bilateral facet joints transfer loads and guide and constrain motions in the spine due to their geometry and mechanical function.

Transverse Process Fracture A transverse process is a bony protrusion from the back of a vertebrae bone in the spine. There is one on each side of every vertebrae in the cervical, thoracic and lumbar spine. Transverse process fracture of the spine include sudden pain in the back at the time of injury.

- Occasionally the fourth lumbar (L4) vertebra is affected, but rarely the remaining lumbar and the thoracic vertebrae. The lumbar vertebrae are stacked one on top of the other with the hook-shaped posterior portion forming a joint (facet) on either side of the midline.

Cervical, Thoracic, and Lumbosacral Medial Branch Nerves For the facet joints, the medial branch nerves are the small nerves that carry pain signals to the brain. Facet joints are pairs of small joints that are situated at each vertebral level of the spine. A facet joint may also be called a zygapophysial joint or a Z-joint. Cervical medial branch nerves are located in a bony groove in the neck. 2  Thoracic medial branch nerves are located over a bone in the mid-back or upper back. 3  Lumbosacral medial branch nerves are found in a bony groove in the low back. 4  See Spinal Cord and Spinal Nerve Roots.

Facet Joint Arthritis Side view of the cervical spine showing the facet joint. X-ray [CT scan] showing the facet joint in cross-section. Paraspinal Muscles. The spine is formed by the bones (vertebral bodies), which are stacked one on top of another. On each side of the vertebral bodies, are tiny joints called facet joints. Arthritic changes and inflammation can develop in these joints, and the nerves to the facet joints can convey severe and diffuse pain.

Vertebrae in the Vertebral Column The vertebral bodies of the lower back are the largest of the spine because they bear the majority of the body's weight. The paired facet joints on the back of the vertebral segments are aligned so that they allow flexion/extension but not a lot of rotation.Most causes of back pain originate in the lumbar spine.he cervical spine has seven vertebral bodies (segments). The top two segments are unique: 1  The first cervical segment (called the atlas) is a ring that does not have a vertebral body. 2  It is attached to the second vertebral body (the axis), which acts as a post that the first vertebral ring rotates around.

There is one on each side of every vertebrae in the cervical, thoracic and lumbar spine. Transverse process fracture symptoms. Transverse process fracture of the spine include sudden pain in the back at the time of injury. There will be decreased range of motion of the affected area of the spine and pain when trying to bend or twist the affected area.

- Structure of a Typical Vertebra. Each vertebra is composed of a body anteriorly and a neural arch posteriorly (fig. 2). The arch encloses an opening, the vertebral foramen, which helps to form a canal in which the spinal cord is housed. Protruding from the posterior extreme of each neural arch is a spinous process and extending from the lateral edges of each arch are transverse processes.

Vertebral column The upper cervical spine has a curve, convex forward, begins at the second cervical vertebra the axis at the apex of the odontoid process known as the dens, and ends at the middle of the second thoracic vertebra; it is the least marked of all the curves.he sides of the vertebral column are separated from the posterior surface by the articular processes in the cervical and thoracic regions, and by the transverse processes in the lumbar region.

Cervical Spine Anatomy On each lateral mass is a superior and inferior facet (zygapophyseal) joint. The superior articular facets are kidney-shaped, concave, and face upward and inward. These superior facets articulate with the occipital condyles, which face downward and outward.
