Normal Center Edge Angle
20-30 degrees
Measurement defines the extent to which the acetabulum covers the top of the femoral head
Center Edge Angle
CEA is the intersection of:
Vertical, fixed reference line
Acetabular reference line
Indicates the extent to which the acetabulum covers the front of the femoral head
Acetabular Anteversion Angle
AAA is formed by the intersection of?
Fixed anterior-posterior reference line
Acetabular reference
