Description

Mutual compression of the spinous processes (radiological formation of bridges) of closely approximated adjacent lumbar vertebrae observed in some types of degenerative diseases. Etiology unknown.

Pain in the neck and shoulders produced by contact of two or more spinous processes on extension of the neck has been described in two patients by Nava of Brazil. Inasmuch as Michotte earlier reported a similar condition in the lumbar region, Nava proposed that this name be used as an eponymic designation.
