Abstract：Objective To reveal the morbidity and classification of osteoarthritis of the atlanto-odontoid joint with MDCT in adults.Methods A series of 700 selected domestic patients (387 female and 313 male) over 18 years old (aged 18.2-88.8 years old, average 46.4 years old) underwent an upper cervical MDCT scan were divided equally into seven age groups in this retrospective study. According to distribution of their age, all of 700 patients were divided into 7 groups, with 100 patients in each group. Multi-planar reconstruction was performed in a 16-slices spiral CT, osteoarthritis of the atlanto-odontoid joint was viewed from any direction and classified into four grades, which were normal, mild, moderate, and severe by Fourth classification criteria. One hundred patients were randomly selected for assessing the reproducibility of MDCT grading.Results The incidence rates of osteoarthritis of the atlanto-odontoid joint in male and female were 54.3%(170/313), 53.2%(206/387). There was no significant difference (χ2=0.082, P>0.05). The incidence of osteoarthritis showed a gradual upward trend (χ2=229.725, P＜0.01). MDCT grading was used to assess the inter-observer reliability( K=0.720).Conclusions The incidence is unrelated to gender, but increases with age gradually. MDCT grading in Osteoarthritis of the atlanto-odontoid joint is stable.
