The thickness, compressibility and elasticity of the IV discs are features that primarily permit movements of the vertebral column. The fifth lumbar spine vertebrae (L5) is part of the greater lumbar region. The bodies of lumbar vertebrae are much wider than they are deep. Compression fractures of the spine usually occur at the bottom part of the thoracic spine (T11 and T12) and the first vertebra of the lumbar spine (L1). The L3-L4 spinal motion segment, positioned in the middle of the lumbar spine, plays an important role in supporting the weight of the torso and protecting the cauda equina (nerves that descend from the spinal cord). See Lower Back Pain Symptoms, Diagnosis, and Treatment. The spinal nerves innervate the skin and the muscles of a specific region. This is typically an unstable fracture. Spinal anatomy.

Conservative treatment may include rest, anti-inflammatory medications, painkillers, steroid injections and drainage. com The vertebral column (also known as the backbone or the spine), is a column of approximately 33 small bones, called vertebrae. For example, the T3 nerve root runs between the T3 vertebra and T4 vertebra. The most important factor in determining the best treatment for a compression fracture is. The C5-C6 spinal motion segment (located in the lower cervical spine just above the C7 vertebra) provides flexibility and support to much of the neck and the head above. ] Any of the 33 bony segments of the spinal column: 7 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 4 coccygeal vertebrae. An intervertebral disc (or intervertebral fibrocartilage) lies between adjacent vertebrae in the vertebral column. These bones are below the cervical and thoracic vertebrae but above the sacrum or pelvis. The commonest of these would be a "compression fracture" of a vertebra (where one of the vertebrae gets squashed by the vertebra above it and fractures) which is usually caused by osteoporosis. Associated Conditions. Hold for a few seconds and release. It is the most delicate of all the 7 cervical vertebrae and lacks a vertebral body and spinous process.

The cervical spine encompasses seven vertebrae and serves as a protection to the spinal cord. Injuries from these accidents can range from mild muscle and ligament strains to more serious fractures. One type of compression fracture is the wedge when the anterior part of the vertebrae collapses creating a triangular shape. Vertebrae are the 33 individual, interlocking bones that form your spinal column. Each vertebra articulates with its neighbour at five different points: first, at the contact point between the main, central bodies of the bones (centra), which is a ball-and-socket joint; then at two projections (prezygapophyses and postzygapophyses) from the centra, with articulating surfaces that lie above and below; and finally the. The major function of the vertebral column is to protect the spinal cord; it also is an attachment for many muscles. They act as supporting structures that hold the vertebrae of the spine together. It becomes larger from the cervical vertebra (C2) to the lumbar vertebra (L5). Within the different regions of the vertebral column, vertebrae vary in size and shape, but they all follow a similar structural pattern. The lumbar region of the spine, more commonly known as the lower back, consists of five vertebrae labeled L1 through L5. Each vertebra has a large hole (vertebral foramen) for the spinal. While innervation can vary from person to. This reflects the importance of the vertebral artery for the human organism. The spinal cord, like the brain, has two major layers of protection. It articulates with the dens of the axis and the occiput, respectively allowing rotation of the head, and flexion, extension and lateral flexion of the head. This may occur anywhere along the spine, but is most common in the lower back (lumbar spine). The irregularly shaped bones form the roughly S-shape of the spinal cord. The word spondylolisthesis (pronounced spohn-di-low-less-THEE-sis) comes from the. The thoracic spine is part of the vertebral column that supports the chest area and provides posterior attachment for the ribs, some thoracic wall muscles, muscles of the upper limb, abdomen, and back.
