Based on the geometric model developed by Netter [11], we determined the different positions of the femoral neck during monopodal support in walking in relation to a fixed frontal plane of reference (relative anteversion). This "relative anteversion" ranges on average from 24 degrees of retroversion at the beginning of support to 15 degrees of anterversion at the end if loading. We then studied the relations possibly existing between relative anteversion and acetabular orientation on the one hand, and the orientation of the resultant of the articular stresses on the other (both being variables during monopodal support in walking). The results showed that relative anteversion is well correlated with variations of position of the acetabulum since, at most, the deviation between the respective axes did not exceed the anatomic deviation due to absolute anteversion of the femoral neck and acetabulum. Lastly, analysis of the relations obtained with the orientation of the resultant of the articular stresses allowed a better comprehension of the functional distribution of forces.
基于奈特（Netter）[11] 所建立的几何模型，我们确定了步行单足支撑期间股骨颈相对于固定额状面参考平面的不同位置（相对前倾）。这种“相对前倾”的范围平均从支撑开始时的24度后倾到负重结束时的15度前倾。然后，我们一方面研究了相对前倾与髋臼方向之间可能存在的关系，另一方面研究了关节应力合力的方向之间可能存在的关系（两者在步行单足支撑期间均为变量）。结果表明，相对前倾与髋臼位置的变化密切相关，因为各自轴线之间的偏差最大不超过由于股骨颈和髋臼的绝对前倾所导致的解剖学偏差。最后，对关节应力合力方向所得到的关系进行分析，有助于更好地理解力的功能分布。
