BACKGROUND: How to evaluate the cervical curvature correctly has been a greatly concern of spine surgeons. In recent studies, cervical curvature index(CCI) and cervical spine angle(C2-7) were often used by foreign researchers.OBJECTIVE: Ishihara method and spine angle(C2-7) method were applied to measure the cervical curvature, and the correlation between the two methods was compared as well.DESIGN: An observational controlled trial based on the patients.SETTING: Department of Orthopaedics of Peking Union Medical College Hospital.PARTICIPANIS: Totally 63 cases including 34 male and 29 female patients with cervical spondylopathy were involved in the Department of Orthopaedics of Peking Union Medical Clooefe Hospital from July 2002 to July 2003.METHODS: The 63 cervical spondylopathy patients' cervical spine lateral X-ray films were evaluated.MAIN OUTCOME MEASURES: Main outcomes: ① The patients' CCI and the cervical spine angle; ② Relationship between their CCI and the cervical spine angle. Secondary outcomes: ① Regressive equation derived from their CCI and the cervical spine angle; ② Comparison of CCI and the cervical spine angle between male and female. RESULTS: The CCI(Ishihara method) was averaged 10. 1 (SD, 11.6), and the cervical spine angle(C2 -7) 17. 5 °(SD, 13.5). A highly significant correlation was found between the two indexes( P＜0.01). Sex and age factors were found to be irrelevant to them.CONCLUSION: The CCI (Ishihara method) and the cervical spine angle (C2-7) are significantly correlated with each other.
