![]() Congenital RetrolisthesisĬongenital retrolisthesis occurs when the bones do not form correctly during fetal development Traumatic Retrolisthesis This can sometimes occur during childhood or adolescence but go unnoticed until adulthood when degenerative changes cause worsening slippage. If this interconnecting bone is broken, it can lead to slippage of the vertebra. Spondylosis refers to a fracture of a small bone, called the pars interarticularis, which connects the facet joint of the vertebra to the one below. Isthmic retrolisthesis is the result of another condition, called “ spondylosis”. Overtime, the bones and ligaments which hold the spine together may become weak and unstable. There are several types of retrolisthesis, often classified by their underlying cause: Degenerative Retrolisthesisĭegenerative retrolisthesis is the most common cause, and is due to general wear and tear on the spine. Radiopaedia includes xray cases of retrolisthesis here. The severity of retrolisthesis is determined by the amount of displacement of the vertebra, with grades ranging from 1 to 4, based on the percentage of displacement. Retrolisthesis can occur in any part of the spine but is most commonly seen in the lumbar (lower back) region. Anterolisthesis, on the other hand, is when there is forward slippage. Retrolisthesis is a form of spondylolisthesis, which is the slipping of one vertebra over another, but specifically refers to the backward displacement of the vertebra. In simpler terms, it refers to the backward shifting of one vertebra on another in the spine. Retrolisthesis is a medical condition characterized by the posterior (backward) displacement of a vertebral body in relation to the one below it.
