不同年龄、性别和类型的特发性脊柱侧凸患者轴向躯干旋转角度与 Cobb 角度的相关性.

BACKGROUND: At present, the measurement of axial trunk rotation angle is widely used to screen scoliosis. Whether this method is suitable for all types of scoliosis is still uncertain. OBJECTIVE: To study the correlation between axial trunk rotation angle and Cobb angle in different ages, genders, and types of idiopathic scoliosis patients, and provide theoretical basis for screening of idiopathic scoliosis. METHODS: Totally 203 idiopathic scoliosis patients aged from 4 to 18 years old were measured in Cobb angle and axial trunk rotation angle. According the age, gender and type, 203 subjects were divided into different groups, and the correlation between Cobb angle and axial trunk rotation angle was calculated in each group. RESULTS AND CONCLUSION: (1) There was a moderate correlation between axial trunk rotation angle and Cobb angle in 203 patients with idiopathic scoliosis (r=0.581, P=0.000). (2) According to age, there was no correlation between Cobb angle and axial trunk rotation angle in 4-9 years old idiopathic scoliosis patients (r=0.516, P=0.155). There was a moderate correlation between the two angles in patients aged 10-18 years (r=0.455, P=0.000). (3) According to type, there was a strong correlation between the axial trunk rotation angle and Cobb angle in patients with type I single curve (r=0.739), a moderate correlation between the two angles in patients with type II double curve (r=0.431), and a weak correlation between the two angles in patients with type III triple curve (r=0.399). The correlation decreased between axial trunk rotation angle and Cobb angle with the increase of the number of side bends. (4) According to gender, the correlation between Cobb angle and axial trunk rotation angle was higher in male patients (r=0.601) than that in female patients (r=0.598). [ABSTRACT FROM AUTHOR]
