The Fulcrum test is used to help detect a femoral stress fracture by creating stress at the suspected site of injury. To perform the test, the examiner places their forearm underneath the femur radial side up (photo A above). The bony ridge along the radius acts as the fulcrum as pressure is applied to the knee. The examiner gradually moves their forearm proximally and repeats the maneuver (photo B above). Pain marks a positive test.
