anterolisthesis definition
Anterolisthesis is a form of spondylolithesis that described the manner of slippage of the vertebra. Anterolisthesis is the condition of the spine that involves the vertebrae. The vertebrae make up the spine and are bones that form an opening to allow a passageway for the spinal cord. To understand what anterolisthesis means it is first. necessary to understand the meaning of the word. vertebrae. Vertebrae are bones that form an opening in. which the spinal cord passes. These bones are stacked. one on top of another, as shown in the picture below. Each individual bone that makes up the vertebrae is. Symptoms of spondylolisthesis may include: 1  Back or buttock pain. 2  Pain that runs from the lower back down one or both legs. 3  Numbness or weakness in one or both legs.  Difficulty 1  walking. Leg, back, or buttock pain that gets worse when you bend over or twist.  Loss of bladder or bowel control, in rare cases. What is Anterolisthesis? The term anterolisthesis is derived from “ante”, a Latin word that means ‘front’ and “listhesis”, a Greek word that means ‘sliding down on a path that is slippery’. Putting the terms together, you will have “antelisthesis” that means a front slide down a path that is slippery. Spondylolisthesis: Back Condition and Treatment. The word spondylolisthesis derives from two parts: spondylo which means spine, and listhesis which means slippage. So, a spondylolisthesis is a forward slip of one vertebra (ie, one of the 33 bones of the spinal column) relative to another. Spondylolisthesis usually occurs towards the base of your spine in the lumbar area. This x-ray shows spondylolisthesis in the lumbar spine. Spondylolisthesis is a condition in which one bone in your back (vertebra) slides forward over the bone below it. It most often occurs in the lower spine (lumbosacral area). In some cases, this may lead to your spinal cord or nerve roots being squeezed. the partial forward dislocation of one vertebra over the one below it, most commonly the fifth lumbar vertebra over the first sacral vertebra. Severity of spondylolisthesis is classified by percentage of slip. Forward movement of the body of one of the lower lumbar vertebrae on the vertebra below it, or on the sacrum. spondylolisthesis. spondylolisthesis. n. Forward displacement of one of the lower lumbar vertebrae over the vertebra below it or on the sacrum. What is Anterolisthesis? Anterolisthesis is defined as a forward slippage of the upper vertebral body in relation to the vertebra below. The progression in the displacement of the involved vertebra can potentially pinch the spinal nerves of the vertebra and may also result in damages in the spinal cord. Medical Definition of Anterolisthesis. Anterolisthesis: The forward positioning of one spinal vertebra in relation to the adjacent vertebra beneath it. Anterolisthesis can be graded: Grade 1 is less than 25% slippage, grade 2 between 25%-50% slippage, grade 3 between 50%-75% slippage, and grade 4 greater than 75% slippage. Symptoms of anterolisthesis depend on the severity, location, and cause.
