Craig's Test

Also Known as: the Ryder Method

Background: This test measures femoral anteversion or forward torsion of the femoral neck.

Procedure: The patient lies prone with the knee flexed to 90 degrees. The examiner palpates the posterior aspect of the greater trochanter of the femur. The hip is then passively rotated medially and laterally until the greater trochanter is parallel with the examining table or reaches it most lateral position. The degree of anteversion can then be estimated, based on the angle of the lower leg with the vertical. (Magee 2002)
