Abstract: Objective To analyze the CT signs and the clinical relevant factors of degenerative osteoarthritis of athnto-odontoid joint.Methods The CT signs and the clinical information of 214 patients received CT scans of skull from June 2011 to April 2012 were analyzed retrospectively.Results One hundred and twenty patients were diagnosed with degenerative osteoarthritis of atlanto-odontoid joint,while 67 of them having subaxial degenerative osteoarthritis at the same time.Forty-three patients had a history of chronic cervical and occipital pain.95.83％ (115/120) patients showed osteophytes in CT scans,while 44.17％ (53/1 20) showed calcification around dens and 24.17％ (29/120) showed joint space obliteration.The incidence rate increased with age.Seventy-seven patients [64.17％(77/120)] appeared cervical and occipital pain.Conclusions Degenerative osteoarthritis of atlanto-odontoid joint shows hyperostosis,osteophytes at the edge of joint,joint space obliteration and calcification around dens in the CT scans.The incidence rate is increased with age and correlated with cervical and occipital pain.
