Femoral Anteversion test (Craig’s test)

Synonym: Trochanteric prominence angle test

Patient position: Prone with knee on test side flexed to 90 degrees

Test procedure: Examiner palpates the greater trochanter and internally and externally rotates the hip until the greater trochanter lies at the lateral most aspect of the hip (the greater trochanter is parallel to the examination table or bed at this point) thereby projecting the femoral head into center of acetabulum.

Angle measurement: Measure the angle of internal or external rotation using the goniometer.

Interpretation:

1. Normal: At birth, the mean anteversion angle is 30 degrees which decreases to 8-15 degrees in adults (angle of internal rotation).
2. Angle >15 degrees: Increased anteversion leads to squinting patellae & pigeon toed walking (in-toeing) which is twice as common in girls.
3. Angle <8 degrees: Retroversion
