title: [Phraseology of disk herniation: an inevitable revision renaming the posterior disk prolapse--retrolapse is better].
abstract: Etymology teaches us to use the term prolapse exclusively for describing the part of the intervertebral disk that has slipped forwards, that is, towards the anterior longitudinal ligament. Consequently, the word retrolapse has to be introduced as the corresponding term in order to designate the posterior slipped disk. The common use of matching pairs like propulsion/retropulsion or prognathism/retrognathia is another justification for the recommended revision.
