[The relationship between the gait of humans and the hip joint structure in the frontal plane].

The forces at the hip joint acting between the femur head and acetabulum are significant for the function properties a lifetime. These forces are determined by the geometry of skeleton and the dynamic of limbs motions. The interaction of hip joint anatomy, gait dynamics, and joint force is described biomechanically. The connections are verified by 35 adults. The results of this investigation allow to conclude that individual variants of macroscopic hip joint anatomy are founded by the relation between maximum loading during gait and hip joint structure. The correlation between the angle of weight-bearing-surface and the hip joint force direction is very significant. For a normal hip joint function, the anatomical structure of the acetabulum is essential more important as that of the coxal femur.
