Spondylolisthesis is a denotes the slippage of one vertebra relative to the one below. Spondylolisthesis can occur anywhere but is most frequent, particularly when due to spondylolysis, at L5/S1 and to a lesser degree L4/5.
Although etymologically it is directionless (see below) and could be applied to both anterolisthesis and retrolisthesis, in practice, however, spondylolisthesis is used synonymously with anterolisthesis. Often, particularly in the lower lumbar spine, it is due spondylolysis (pars interarticularis defects) 6.
History and etymology
Spondylolisthesis is from the greek spondylos (σπονδύλους) meaning vertebra and listhesis (ολίσθηση) meaning slippage 6.
