[Cervical spondylosis].

Japan has now become an aging society. In 2014, people aged more than 65 years old accounted for 25.1% of Japan's entire population. Aging is associated with an increased risk of problems related to the locomotive organs. Deterioration of locomotive ability causes falls or tumbles, which would be a threat to good health and longevity of aged people. To maintain the locomotive ability of the elderly, therefore, the Japanese Orthopaedic Association starts a campaign to promote awareness and prevention of "locomotive syndrome". Cervical spondylosis is a disorder for age-related wear affecting the disks and vertebrae of cervical spine. It would also be a cause of "locomotive syndrome". Here, we give an outline of this disease and introduce its diagnosis and treatment.
