If the displacement is more than 2 millimeters, your doctor may diagnose you with retrolisthesis (eg, Grade 1). Depending on the outcome of your neurological exam and review of symptoms, your doctor may order additional imaging tests, such as a CT or MRI scan.Tags: Math Homework Help OnlineRace In My Community EssayTemplate For A Research PaperHuman Rights In China EssayEssays Heroic DeedBusiness Plan PakistanBusiness Budget PlansEasy Science Research Paper Topics
Each vertebra is separated by a cushion of intervertebral discs.
These discs consist of an inner core called the nucleus pulposus.
Another term for either disorder is vertebral displacement. Both disorders can develop at any vertebral level in the spinal column, although the cervical (neck) and lumbar (low back) regions are more common.
The neck is subjected to stresses as it supports the , and absorbs and distributes forces while at rest and during physical function.
The diagnosis of retrolisthesis involves a physical examination and neurological evaluation that include details about your medical history and symptoms.
Thereafter, standing x-ray imaging of your spine is performed (eg, anterior, posterior, lateral).
They’re held intact by a strong outer ring of ligament fibers called the annulus fibrosus.
Retrolisthesis occurs when a single vertebra slips and moves back along the intervertebral disc underneath or above it. If the vertebra slips forward, it’s called spondylolisthesis. They’re based on the displacement of the vertebra in relation to adjacent vertebra.
Similar to spondylolisthesis, the severity of a retrolisthesis is graded from 1 to 4 based on the percentage of posterior (backward) displacement of the vertebral body’s foramen (neuroforamen).
The grade of a retrolisthesis is important to assessing the stability of the adjacent facet joint.
