Abstract: ObjectiveTo study the relationship between the incidence of cervical osteophytosis and the age.MethodsThree hundred X-ray films (male 159, female 141) on lateral cervical position were observed. The patients were divided as group A (age <30), group B (age 30～39), group C (age 40～49), group D (age 50～59), group E (age 60～69) and group F (age 70～90). The osteophytosis on superior or inferior cervical vertebral body were marked.ResultsThe incidences of osteophytosis were group A 0%, group B 4.0%～4.7%, group C 20.0%～23.3%, group D 38.7%～39.2%, group E 56.7%～60.0%, group F 72.7%～80.9%. There was significant differences between the group B and group C, group C and group D, group D and group E, group E and group F (P<0.05～0.01). The common places of the osteophytosis were C₅ and C₆, while often on C₆ in male and on C₅ in female.ConclusionThe incidence of cervical osteophytosis increases following age increasing. The most place of the osteophytosis is on C₅ and C₆.
