Objective: To explore the relationship between the abnormality curvature of cervical spine and pathogenesy of cervical spondylosis, in order to provide a new way in diagnosis of cervical spondylosis.
Methods: There were two groups in the study, which were non-cervical spondylosis group (with heath adults) and cervical spondylosis group. From March 2006 to December 2008, 333 patients (out-patients in department of orthopaedics of Shuguang hospital) in cervical spondylosis group, which were 119 males, 214 females with an average age of (48.11 +/- 12.21) years. There were 73 subjects in non-cervical spondylosis group, which was 18 males, 55 females with an average age of (45.99 +/- 11.47) years. Based on the lateral view X-ray pictures of cervical spine, the abnormality curvature and character of cervical spine were studied in two groups.
Results: The incidence rate in abnormality curvature of cervical spine in cervical spondylosis group (achieved to 95.50%) was more than that of non-cervical spondylosis group, there was significant difference between two groups (P = 0.000 < 0.01). Furthermore, the patterns of the abnormality curvature of cervical spine in cervical spondylosis group was complicated and variegated, of which physiological curvature diminished had 23.12% (77 cases), turn straight had 40.84% (136 cases), increased had 0.60% (2 cases), recurved had 12.01% (40 cases), S shape had 4.20%(14 cases), contra-S shape had 2.70% (9 cases), upper flex and lower straight had 4.50% (15 cases), upper straight and lower flex had 7.51% (25 cases).
Conclusion: The abnormality curvature of cervical spine may be an X-ray diagnostic indication to the cervical spondylosis, which is complicated and variegated. It will provide the guidance for the diagnosis and treatment of cervical spondylosis.
