A Natural-Position X-Ray for Evaluating Cervical Vertebra Physiology Curvature Before and After Conservative Treatment
Abstract
BACKGROUND Abnormal physiological curvature is one of the symptoms of early cervical spondylosis. An X-ray taken with the patient standing in a natural position can best reflect the real cervical vertebra physiological curvature. The purpose of this research was to study the value of natural-position X-ray in evaluating cervical vertebra physiology curvature before and after conservative treatment. MATERIAL AND METHODS This study included 135 participants of different ages diagnosed with cervical disease and who received conservative treatment for more than 12 months. The natural- and regular-position X-rays were performed before and after treatment. The positive change of D value in Borden's measurement and C2~7 Cobb angle should be recognized as an improvement of cervical vertebra physiology curvature. RESULTS Before treatment, the C2~7 Cobb angle of the regular-position group was larger than that of natural-position group. After treatment, the C2~7 Cobb angle of the natural-position group was larger than that of the regular-position group, and the D value increased after treatment in both groups. The effective rate of cervical physiological curvature of the natural-position group was higher than that of the regular-position group. CONCLUSIONS Natural-position X-ray has greater accuracy in evaluating cervical vertebra physiology curvature before and after conservative treatment compared with regular-position X-ray.
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 135 participants or records.
