[Cervical spondylolisthesis in skeletal fluorosis. A case report]

The authors report an uncommon complication in cervical skeletal fluorosis. It is a cervical spondylolisthesis at C5-C6 level complicated by a radiculomyelopathy described in a man living in an endemic area for fluorosis. After 3 years, a spontaneous stabilization of the cervical spine with a posterior calcification of the supraspinal and interspinal ligaments has caused an improvement of the neurological symptomatology.
