28
Q

The acetabulum covers the top of the femoral head. This is measured as the intersection of a vertical, fixed reference line (stippled line) with the acetabular reference line (bold solid line) that connects the upper lateral edge of the acetabulum with the center of the femoral head.

Q

Implication for the Center Edge Angle/Angle of Wiberg

A

The more vertical the acetabular reference line, the smaller the CEA. (means less superior coverage of the femoral head)

30
Q

This measurement indicates the extent to which the front to which the acetabulum covers the front of the femoral head.

A

Acetabular Anteversion Angle

31
Q

This measurement defines how much the acetabulum covers the top of the femoral head.

A

Angle of Wiberg/ Center Edge Angle

32
Q

Acetabular Anteversion Angle is formed by _____.

A

The intersection of a fixed anterior-posterior reference line with an acetabular reference line that connects the anterior and posterior rim of the acetabulum.

33
Q

The Implication of Acetabular Anteversion Angle

A

Inversely Proportional: Larger acetabular anteversion angle means less acetabular containment of the anterior side of the femoral head.

34
Q

Femoral Anteversion/Femoral Torsion is formed by?

A

*Axis of femoral condyles at the knee
*Axis of the femoral head

35
Q

A

lateral femoral torsion (retroversion)

37
Q

If the femoral anteversion has a less 15 degrees angle, it means?

A

medial femoral torsion (anteversion)

Q

If increased Neck-Shaft Angle, what will happen?
