title: [Chronic functional dislocation of the cervical spine with radiculo-spinal effects. Discectomy by anterior route and fusion without graft].
abstract: X ray dynamic study of cerevical spine movements in 12 patients with neurological impairment has shown an abnormal mobility between two vertebrae in the anterior or posterior direction. This abnormal mobility which has been called functional dislocation, is situated usually over major discarthrosic lesions rather than under. This dislocation, which appears during voluntary and automatic movements of the head and neck has been qualified chronic. A discectomie through an anterior surgical approach and a bony fusion of vertebral bodies without any graft at the dislocation site lead to 10 good results. 2 failures have been imputed to the fact that there was a 10 years evolution of a tetraplegia before operation. The pathogenesis of chronic functional dislocation of the cervical spine is discussed with regard to compression and stretching of the spinal cord, roots and arteries of both. Traumatism of vertebral arteries during dislocation remain under discussion.
