Spondylolisthesis /ˌspɒndɪloʊlɪsˈθisɪs/ SPON-dill-oh-lis-THEE-sis is the forward displacement of a vertebral bone in relation to the natural curve of the spine, most commonly occurring after a fracture, and most often the fifth lumbar vertebra. Backward displacement is referred to as retrolisthesis. When occurring in conjunction with scoliosis, the shortened term "olisthesis," may sometimes be used instead.

A hangman's fracture is a specific type of spondylolisthesis where the second cervical vertebra (C2) is displaced anteriorly relative to the C3 vertebra due to fractures of the C2 vertebra's pedicles.

Symptoms of spondylolisthesis include:

Other symptoms may include tingling and numbness. Coughing and sneezing can intensify the pain. An individual may also note a "slipping sensation" when moving into an upright position. Sitting and trying to stand up may be painful and difficult.
