What is L in spinal cord?
What is L in spinal cord?
The lumbar spine is located in the lower back below the cervical and thoracic sections of the spine. It consists of five vertebrae known as L1 – L5. These lumbar vertebrae (or lumbar bones) contain spinal cord tissue and nerves which control communication between the brain and the legs.
What is the normal diameter of L4 L5?
The AP diameter of the spinal canal at L4-L5 level in male control group are between 14.66 and 16.5 mm and in case group, the same is between 10.92 and 12.29 mm [Table 3].
What is narrowing of left lateral recess?
Lateral recess stenosis is defined as the narrowing of the sides of the bony tubular passageway, the lateral recess. This narrowing causes a loss of space which may result in pressure on the exiting nerve, causing a range of different symptoms. Insignificant narrowing may also occur where no symptoms are presented.
What is L4 in your back?
The L4 and L5 are the two lowest vertebrae of the lumbar spine. Together with the intervertebral disc, joints, nerves, and soft tissues, the L4-L5 spinal motion segment provides a variety of functions, including supporting the upper body and allowing trunk motion in multiple directions.
What is AP diameter?
The anteroposterior (AP) diameter of the normal adult male cervical canal has a mean value of 17-18 mm at vertebral levels C3-5. The lower cervical canal measures 12-14 mm. An adult male without spinal stenosis has a diameter of 16-17 mm in the upper and middle cervical levels.
How is lateral recess stenosis repaired?
Surgical therapies for treating foraminal stenosis include: Laminectomy — A procedure in which the lamina of the affected vertebrae (the portion of the vertebral arch that forms the “roof” of the spinal canal) is removed or trimmed to widen the foramen and create more space for the spinal nerves.
How is tetraplegia causes?
Tetraplegia is a paralysis caused by an injury of the cervical spinal cord. This can result in a partial or total sensory and motor loss of the four limbs and torso. The injuries that occur above level C4 often result in respiratory deficiency.
