Three-dimensional illustrations of the technique for ARO using a bone model. Anteroposterior a and lateral b views show the two osteotomy lines. The first osteotomy is made in the plane perpendicular to the femoral neck, and the second line is made directing to the first osteotomy plane, just above the lesser trochanter. Anteroposterior view c showing the bone model after 90° of anterior rotation
