When refering to evidence in academic writing, you should always try to reference the primary (original) source. That is usually the journal article where the information was first stated. In most cases Physiopedia articles are a secondary source and so should not be used as references. Physiopedia articles are best used to find the original sources of information (see the references list at the bottom of the article).If you believe that this Physiopedia article is the primary source for the information you are refering to, you can use the button below to access a related citation statement.
Lumbar Vertebrae Verebral BodiesThe Lumbar Vertebrae are larger and heavier than vertebral bodies in other regions. The lumbar vertebral body is kidney shaped when viewed superiorly, so is wider from side to side than from front to back, and a little thicker in front than in back with a thin cortial shell which surrounds cancellous bone. The posterior aspect of the vertebral body changes from slightly concave to slightly convex from L1 - L5 with an increasing diameter due to the increased load carried at each body.The main weight of the body is carried by the vertebral bodies and disks.
How can the answer be improved?
The lamina, facets and spinous process are major parts of the posterior elements that help guide the movement of the vertebrae and protect the spinal cord.Vertebral ForamenThe vertebral foramen is triangular in shape and is larger than in the thoracic vertebrae but smaller than in the cervical vertebrae.Bony Structures PediclesThe pedicles originate posteriorly and attach to the cranial half of the body forming the vertebral arch with the laminae. Magnetic resonance imaging (MRI)Conceptual links between MRI findings and spine-related symptoms.

With respect to chronic low back pain or radicular symptoms, MRI findings does not explain the vast majority of incident symptom cases. Treatment Invasive treatment. percutaneous vertebroplasty: percutaneous intraosseous methylmethacrylate cement injection to treat osteoporotic vertebral compression fractures and spinal column neoplasms. kyphoplasty: Kyphoplasty is a type of vertebral augmentation for compression fractures. Lumbar Fusion: The goal of a lumbar fusion is to stop the pain at a painful motion segment in the lower back. Most commonly, this type of surgery is performed for pain and disability caused by lumbar degenerative disc disease or a spondylolisthesis.There are also many surgical approaches to performing spinal fusion, such as ALIF, PLIF, XLIF, TLIF, posterolateral gutter fusion, anterior/posterior fusion, and certain minimally invasive approaches.Physiotherapy.: Large forces are not required to separate the vertebrae.
Vertebral separation could provide relief from radicular symptoms by removing direct pressure or contact forces from sensitised neural tissue.: Physiotherapists use manual mobilisation for differents patologies of the lumbar spine. Good knowledge of the appropriate technique is needed as well as take into account some contraindications, for example, high velocity spinal manipulation techniques are contraindicated in individuals with osteoporosis.
