Abstract

Standing posture is made possible by hip extension and lumbar lordosis. Lumbar lordosis is correlated with pelvic parameters, such as the declivity angle of the upper surface of the sacrum and the incidence angle, which determine the sagittal morphotype. Incidence angle, which is different for each individual, is known to be very important for up-right posture, but its course during life has not yet been established. Incidence angle was measured on radiographs of 30 fetuses, 30 children and 30 adults, and results were analysed using the correlation coefficient r and Student's t test. A statistically significant correlation between age and incidence angle was observed. Incidence angle considerably increases during the first months, continues to increase during early years, and stabilizes around the age of 10 years. Incidence is a mark of bipedism, and its role in sagittal balance is essential.

摘要

站立姿势通过髋关节伸展和腰椎前凸得以实现。腰椎前凸与骨盆参数相关,如骶骨上表面的倾斜角度和入射角,这些参数决定了矢状面形态类型。入射角因人而异,已知对直立姿势非常重要,但其在生命过程中的变化过程尚未明确。对30例胎儿、30例儿童和30例成人的X线片测量入射角,并使用相关系数r和学生t检验分析结果。观察到年龄与入射角之间存在统计学显著相关性。入射角在最初几个月显著增加,在早年持续增加,并在10岁左右稳定下来。入射角是两足行走的标志,其在矢状面平衡中的作用至关重要。
