Understanding the Craig's Test (or Ryder's Test) Assessment
To determine the approximate amount of **femoral anteversion** (or retroversion) and assess for abnormal hip rotation alignment.
Watch How It's Done
How do I start?
Patient is prone with the knee flexed to 90°.
What happens?
The examiner passively **internally and externally rotates the hip** until the greater trochanter of the femur is felt to be **most parallel** to the examination table (i.e., at its most lateral point). The degree of internal rotation is then measured.
In Plain English
What Does a Positive Result Mean?
Normal anteversion is typically around **8° to 15° of internal rotation**. **Excessive internal rotation** (>15°-20°) suggests femoral anteversion. **Excessive external rotation** or minimal internal rotation (<8°) suggests femoral retroversion.
Helpful Tip:
This test measures a bony alignment and is used to explain gait abnormalities or predisposition to pathology.
Safety First
This guide is to help you understand what happens in a clinic. Do not try to diagnose yourself. If you have severe pain, swelling, or cannot put weight on your leg, please visit an urgent care center or your doctor immediately.
Other Hip Tests
Ely's Test (Prone Rectus Femoris Contracture Test)
To assess for **tightness or contracture of the Rectus Femoris** muscle (a hip flexor and knee extensor).
FADIR (Flexion, Adduction, Internal Rotation) Test
To provoke symptoms associated with **Femoroacetabular Impingement (FAI)**, particularly **Anterior/Pincer Impingement** or **Acetabular Labral Tears**.
Fulcrum Test
To screen for a **Stress Fracture of the Femoral Shaft**.
Hip Quadrant Test (or Scour Test)
To assess the integrity of the **articular surfaces of the hip joint** (femoral head and acetabulum) and detect defects like osteochondral lesions or loose bodies.
