Femur

Structural variations:

  1. Coxa valga/varum (frontal plane).
  2. Femoral head angle (transverse plane) – angle between femoral condyles and femoral neck (post image).
  3. Shaft torsion in transverse plane.
  4. Condyle levels (genu valga/varum)

The femoral neck normally has >12′ anteversion with 35′ being excessive.
Retroversion is considered <8′ anteversion.
