ABSTRACT

Introduction: Interpretation of cervical curvature in acute acceleration injury of the cervical spine is highly uncertain. Some authors suggest that loss of lordosis is a sign that adversely affects the prognosis of these patients. Other authors suggest that these findings are normal variables. Objective: To determine the normal value of cervical curvature and realize a comparative analysis between healthy subjects and patients with acute acceleration injury of the cervical spine, and to identify the level of correlation between cervical curvature, intensity of symptomatology, evolution time and age in patients. Material and methods: Cross-sectional, comparative, observational, prospective and correlative study of cervical curvature between 110 patients and 110 healthy subjects. Results: The mean value of cervical curvature was 11.7° SD 11.9° and 9.7° SD 10.7° in patients and in healthy subjects respectively. There was no significative difference between both mean values (a = 0.05). The adopted value for cervical curvature in both groups have little tendency to be minor while age of subjects decrease too, existing a minimal correlation in patients (r = 0.26) and in healthy subjects (r = 0.32). There is no correlation between cervical curvature, symptomatology and evolution time. Conclusions: Cervical curvature has great variety of statistical patterns of alignment. The predominant pattern is lordotic. No lordotic cervical curvature observed in patients with acute acceleration injury of the cervical spine, is a no pathologic anatomic variant although statistically infrequent observed in healthy subjects too.
