RESUMEN
OBJECTIVE: To investigate the clinical features of patients with cervical spondylosis. METHODS: Questionnaires were provided and X rays were examined in 1 009 people with different occupations, ages, and sexes. RESULTS: All the patients were diagnozed as cervical spondylosis. Of them, cadres occupied 78.83%, technologists made up 74.21%, and accountants 58.70%; nervous and long-time working people accounted for 59.75%; high and middle pillow-lovers occupied 80.03%. Imaging features: most of the degenerative changes of cervical spine were located between C5-6 (40.79%), C4-5 (26.29%), and C6-7 (18.20%). Patients with vertebral osteophyte were 65.75%, intervertebral space narrow 36.87%, intervertebral foramen narrow 29.19%, and physiological curve change 31.03%. CONCLUSION: This epidemiologic investigation is important, which can further understand the cause of cervical spondyiosis, and strengthen its prevention and treatment.
