Figure 6.
Cross‐table X‐ray of the right hip (A); Alpha angle (B)–circumference of the femoral head; line A which connects the head center of the femoral neck and line B connecting the head center witht the point of beginning asphericity of the head‐neck junction. An angle exceeding 50° is an indicator of an abnormally shaped femoral head‐neck junction; Anterior offset (C)–two horizontal lines touching the anterior femoral head (line C) and femoral head‐neck junction (line D). The distance between both lines corresponds to the anterior offset (line E).
