History of Baastrup disease

1825 – Mayer reported on fluid filled cavities between overgrown lumbar spinous processes in soldiers with back pain. Mayer described the phenomenon as ‘diarthrosis interspinosae’

1929James Frederick Brailsford (1888-1961) described findings of ‘interspinous arthritis‘ in patients with back pain exacerbated in extension and alleviated in flexion. He termed the physical anomaly ‘kissing spines

1933 – Danish radiologist Christian Ingerslev Baastrup (1855–1950) described pathologic changes that occur in adjacent lumbar spinous processes and the soft tissues between them, which are associated with back pain. Demonstrated on radiologic assessment of patients who had pain in the back when standing erect, which was relieved by bending forward.
