What Is It?

Baastrup’s syndrome (aka “kissing spines”) results from osteoarthritis of spinous processes (usually lumbar). The spinous processes rub up against each other which leads to hypertrophy and sclerosis. This can cause a patient pain that is exacerbated with extension and relieved with flexion. The disease is named after Christian Ingerslev Baastrup, a Danish radiologist (1855-1950).
