title: Odontoid fracture complicating ankylosing hyperostosis of the spine.
abstract: Ankylosing hyperostosis of the spine (Forestier's disease) is a distinct clinical entity which must be differentiated from ankylosing spondylitis (Marie-Strumpell's disease) and hypertrophic spondylosis. In the case presented, the distinction was made by clinical, roentgenographic, and postmortem pathologic findings. This case had the unique and previously unreported feature of complication by a fracture of the odontoid. The patient's particular circumstances led to the decision to treat the fracture by posterior arthrodesis, though this is not necessarily recommended for all spinal fractures occuring in this disease.
