Trethowan's sign

Authoring team

Trethowan's sign is positive in slipped femoral epiphysis.

If an anteroposterior view of the hip joint is taken then a line drawn along the superior surface of the neck should pass through the femoral head. If the line remains superior to the femoral head then this is termed Trethowan's sign.
