Wasp-waist sign (spine)

Last revised by Marcin Czarniecki on 27 Jul 2022

The wasp-waist sign is a radiographic appearance seen in patients with Klippel Feil syndrome. It results from fusion of the vertebral bodies such that the anteroposterior diameter at the level of the affected discovertebral joint is smaller than the diameter at the superior and inferior limits of the vertebrae adjacent to uninvolved discs.
