Musculoskeletal ImagingBaastrup's disease
(Christian Baastrup, 1885 - 1950, Danish radiologist), an abnormality also known as kissing spines, in which the spinous processes of adjacent vertebrae are in close approximation or actual contact and may undergo reactive eburnation (Fig.1). In this disorder, excessive lordosis may lead to degeneration of intervening ligaments. The spinous processes may appear enlarged.

AP (a) and lateral (b) radiographs of the lumbar spine demonstrate narrowing of the distance between the hypertrophied spinous processes. Also note the flattening and reactive eburnation of the spinous processes of adjacent vertebrae.
