A simple static three-dimensional mathematical model of an adult human hip in one-legged position is used in order to estimate the resultant force of the hip muscles and the contact force in the hip joint for different pelvic shapes. The variation of pelvic shape was simulated by changing the components of the radius vectors of the muscle origins on the crista iliaca and by changing the interhip distance. It is concluded that the magnitudes of the hip muscle resultant force and the hip joint contact force are minimal for the high, laterally inclined pelvis with small interhip distance and maximal for the shallow, steep pelvis with great interhip distance.
为了估算不同骨盆形状下单腿站立时成人髋关节的髋部肌肉合力和髋关节接触力，使用了一个简单的成人单腿站立位髋关节静态三维数学模型。通过改变髂嵴上肌肉起点半径向量的分量以及改变两髋间距来模拟骨盆形状的变化。得出的结论是，对于髋间距小的高且外侧倾斜的骨盆，髋部肌肉合力和髋关节接触力的大小最小；而对于髋间距大的浅且陡峭的骨盆，其大小最大。
