[Post-traumatic and symptomatic lumbar intertransverse process bone bridge. Apropos of a case: review of the literature].

Osseous bridging of lumbar transverse processes is very seldom seen. A review of the literature has revealed only thirty-six reports. The first cases were thought to be of congenital origin. Subsequently however, the post-traumatic nature of osseous bridging was proved in ten cases. It is obviously a peculiar localization of myositis ossificans. We report a new case, with proof of the post-traumatic nature, associated with symptoms of sciatica.
