2. Fig. 1
The hatched area indicates the harvest locations of the osteochondral specimens. Specimens (diameter 10 mm, height approx. 3 mm) were obtained (a) from the cam deformity of symptomatic FAI patient and (b) from the antero-superior femoral head near the head and neck junction from normal cadaveric donors.

3. Fig. 2
Single slice (a) and 3D representation (b) of the VOI used to determine the trabecular architecture. The dashed line in (a) represents the bounding box for one particular section, which was reduced by 5% on each side to account for some irregularities in the shape of the beam specimens. Figure (b) shows a 3D representation of the VOI in light gray. The dark gray in (a) and (b) indicates the bone that was omitted form the analysis.

4. Fig. 3
Three-point bending test setup. The displacement of the beam specimens was measured on the tensile side of the beam at mid-span with a custom low stiffness CDMD to minimize the effect of local bone crushing.

5. Fig. 4
Finite element mesh of a typical specimen showing the applied boundary conditions. Locations A and B, corresponding to the cylinders supporting the specimen, were constrained in the vertical direction but free rotate and translate in the horizontal plane. Location C, where the vertical displacement was applied, was constrained in the horizontal plane and free to rotate.
