Valgus Position of the Femoral Neck

Valgus deformity of the femoral head (valgus deviation of the neck of the femoral head) is a displacement of the center of gravity of the neck, directed inward and anteriorly, at an angle of 40-80°. It arises as a consequence of the fact that the articular surface of the acetabulum is not deep enough - the tibia of the femur “does not fit” in it with the entire articular cartilaginous surface and protrudes downward. With valgus deformity, the angle of articulation of the hip joint increases, the femoral head is more displaced towards the center of the pelvis. The hip joint exists in a tense state. As a result, severe pain may occur. If the deformity of the femoral neck occurs in childhood or adolescence, then it becomes chronic and leads to various forms of arthrosis.
