Stress nephogram of the Bespoke 3D-printed titanium alloy plates. a–f Changes in the maximum displacement of the hip joint in the upright position and at 15° abduction, 30° abduction, 45° abduction, 15° anteflexion and 30° flexion, respectively. As seen in the nephogram, as the hip joint abducts, the maximum displacement gradually shifts from the plate on the inner lower side of the blocked quadrilateral area to the screws fixed to the posterior column and the penultimate flank behind the arcuate line of the plate. As the hip joint flexes forwards, the migration of the maximum displacement is not obvious
