Craig's test for femoral anteversion/retroversion
Craig's test for femoral anteversion/retroversionA clinical test used to identify femoral torsion.
The patient lies prone with the knee of the affected leg flexed to 90°; the examiner palpates the posterior aspect of the greater trochanter, measuring the angle formed between the vertical axis extending from the tabletop and the longitudinal axis of the lower leg.
The angle measured is outside the normal range of 8–15°. Significantly greater than 15° defines femoral anteversion (internal torsion); significantly less than 8° defines femoral retroversion (external torsion).
