400万到600万年前，人类谱系向习惯性两足行走的转变，创造了与我们最近的近亲黑猩猩相比，在形态和功能上不同的人类骨盆。骨盆形状的进化变化是人类向习惯性两足行走过渡所必需的。骨骼解剖结构的这些变化导致肌肉功能的改变，影响双足步态。此外，骨盆存在正常的性别特异性变异，髋臼也存在异常变异。在步态过程中，骨盆在三个平面内移动，以产生平稳和有效的运动。尽管骨盆结构存在差异，但这些运动中细微的性别特异性差异可能有助于经济步态。髋臼结构异常，尤其是髋臼发育不良时，骨盆和髋关节的运动也可能改变。Anat Rec，300：633-642，2017。(C)2017年Wiley Periodicals，Inc.
The shift to habitual bipedalism 4-6 million years ago in the hominin lineage created a morphologically and functionally different human pelvis compared to our closest living relatives, the chimpanzees. Evolutionary changes to the shape of the pelvis were necessary for the transition to habitual bipedalism in humans. These changes in the bony anatomy resulted in an altered role of muscle function, influencing bipedal gait. Additionally, there are normal sex-specific variations in the pelvis as well as abnormal variations in the acetabulum. During gait, the pelvis moves in the three planes to produce smooth and efficient motion. Subtle sex specific differences in these motions may facilitate economical gait despite differences in pelvic structure. The motions of the pelvis and hip may also be altered in the presence of abnormal acetabular structure, especially with acetabular dysplasia. Anat Rec, 300: 633-642, 2017.
