What is the Craig's Test (Ryder Method) used for?

Measuring Femoral Anteversion (internal twist of the femur).

How do you perform the Craig's Test (Ryder Method)?

Position: Patient lies prone with knee flexed to 90°. Action: Palpate the greater trochanter while rotating the hip. Find the point where the trochanter is most prominent laterally (parallel to table).

What is a positive result for the Craig's Test (Ryder Method)?

Normal: 8-15° of internal rotation.Anteversion: >15° (Associated with "toeing in").Retroversion:

What is the diagnostic accuracy of the Craig's Test (Ryder Method)?

Highly accurate when compared to intraoperative measurements.

Craig's Test (Ryder Method) – Hip Special Test

What is it used for?

Measuring Femoral Anteversion (internal twist of the femur).

How to Perform

Position: Patient lies prone with knee flexed to 90°.
Action: Palpate the greater trochanter while rotating the hip. Find the point where the trochanter is most prominent laterally (parallel to table).

Interpretation of Results

Normal: 8-15° of internal rotation.
Anteversion: >15° (Associated with "toeing in").
Retroversion: <8° (Associated with "toeing out").

Diagnostic Accuracy

Highly accurate when compared to intraoperative measurements.

Clinical Context & Limitations

The Craig's Test (Ryder Method) should be considered as one component of a comprehensive musculoskeletal assessment. No single special test has perfect diagnostic accuracy; thus, clinical decision-making should integrate test results with patient-reported symptoms, mechanism of injury, functional impairment, and relevant imaging.

Clinicians should be aware of potential false-positive results in patients with pain sensitisation, muscle guarding, or poor relaxation. For the Hip region, combining the Craig's Test (Ryder Method) with complementary examination tests significantly improves overall diagnostic confidence.
