What is a LS spine series?
The lumbar spine series is comprised of two standard projections along with a range of additional projections depending on clinical indications. The series is often utilized in the context of trauma, postoperative imaging and for chronic conditions such as ankylosing spondylosis.
Where is the L 5 in the spine?
The fifth lumbar spine vertebrae (L5) is part of the greater lumbar region. To the human eye, this is the curve just above the buttocks, which is also commonly referred to as the small of the back.
What is the anatomy of the spine?
The normal anatomy of the spine is usually described by dividing up the spine into three major sections: the cervical, the thoracic, and the lumbar spine. (Below the lumbar spine is a bone called the sacrum, which is part of the pelvis). Each section is made up of individual bones, called vertebrae.
What does L spine AP mean?
The lumbar spine anteroposterior or posteroanterior view images the lumbar spine in its anatomical position. The lumbar spine generally consists of five vertebrae (see: lumbosacral transitional vertebra).
What is mild lumbar spondylosis?
Lumbar spondylosis is the term given to normal wear and tear of the lumbar (lower back) spinal discs. As we age, spinal discs lose moisture and shrink, bone spurs develop, and bones because weaker. While many people over 50 experience mild lumbar spondylosis, most experience no symptoms.
What can a MRI of the lumbar spine show?
An MRI of the lumbar spine shows the bones, disks, spinal cord, and the spaces between the vertebral bones where nerves pass through.
What is L5 and S1?
The L5-S1 spinal motion segment, also called the lumbosacral joint, is the transition region between the lumbar spine and sacral spine in the lower back. L5-S1 helps transfer loads from the spine into the pelvis and legs.
What are the 5 parts of the spine?
The spine is composed of 33 bones, called vertebrae, divided into five sections: the cervical, thoracic, and lumbar spine sections, and the sacrum and coccyx bones. The cervical section of the spine is made up of the top seven vertebrae in the spine, C1 to C7, and is connected to the base of the skull.
What are the 4 parts of the spine?
Typically, the spine is divided into four main regions: cervical, thoracic, lumbar and sacral.
Where is the center of the L spine?
The long axis of the body should be parallel to the long axis of the table. The spine is centered to the midline of the grid. The lumbar spine is approximately 2 inches medial to the elevated anterior superior iliac spine in the oblique position. The arms are in a comfortable position.
What is the name of the vertical cut in the spine?
The CORONAL PLANE , also called the FRONTAL PLANE , is a vertical cut that divides the body into front and back sections. Physicians look at the coronal plane when they view an A-P (anterior-posterior) x-ray of the spine to evaluate scoliosis. 3. Anatomical Planes Lateral X-ray of a kyphotic spine in the sagittal plane.
Where is the lumbar spine located in the body?
Lumbar Spine Anatomy Video. The lumbar region is situated between the thoracic, or chest, region of the spine, and the sacrum. The lumbar spine typically has a slight inward curve known as lordosis. The lower back region contains large muscles that support the back and allow for movement in the trunk of the body.
How are the five vertebrae of the lumbar spine connected?
These muscles can spasm or become strained, which is a common cause of lower back pain. The five vertebrae of the lumbar spine are connected in the back by facet joints, which allow for forward and backward extension, as well as twisting movements.
How is the sagittal view of the spine seen?
The sagittal view is seen by surgeons on a lateral x-ray of the spine. 4. Anatomical Planes CT Scan of a thoracic vertebra in the axial plane. The AXIAL or TRANSVERSE PLANE is a horizontal cut that divides the body into upper and lower sections. To best view the axial plane of the spine, surgeons will often obtain a CT scan with axial cuts.
