Anterolisthesis is typically graded using the meyerding scale, which assigns one of five grades according to how much slippage has occurred. The grade reflects the percentage of dislocation the vertebra has. The severity of anterolisthesis is determined by the amount of slippage, categorized into four grades:
What is Anterolisthesis Symptoms, Grades and Its Treatment
What does the grade of anterolisthesis mean?
Anterolisthesis is graded based on the degree of slippage of one vertebral body on the adjacent vertebral body.
In anterolisthesis, the upper vertebral body is positioned abnormally compared to the vertebral body below it. Anterolisthesis severity can be graded by the meyerding classification and its. Its severity can be graded by the meyerding classification and. More specifically, the upper vertebral body slips forward on the one below.
Grade 2 involves between 26 to 50 percent slippage, grade 3 involves 51 to 75. The percentage of the vertebra that has slipped forward or backward out of alignment will dictate what the grading is, with grade 1 being the most minor; Grade 1 slippage involves less than 25% of the vertebra. This misalignment can affect the stability of the spine, potentially leading to.
Slippage up to 25% of the vertebral body width.
The percent is based upon what percent one vertebrae is shifted over the. Anterolisthesis is usually detected in the 4 th and 5 th lumbar vertebrae and is one of the types of spondylolisthesis, describing the manner in which the vertebra has slipped. The term anterolisthesis refers to anterior displacement (forward slip) of a vertebral body relative to the one below. Grade 1 anterolisthesis occurs when the vertebra slips less than 25 percent in front of the vertebra below it.
