Fig. 2

Radiography of all groups: In the untreated group, femoral head has collapsed with an abnormal contour and increased density (see arrow in a1, a2). BMSCs group (a2) low density shadow, centrally observable necrosis of femoral head. Magnesium rod group (b2) no necrosis, looming magnesium alloy, less obvious low density area as show the arrows. In c1, c2, d1, d2 the femoral head has not collapsed. The density and the shape are nearly normal. The magnesium rod/BMSCs group (c2) shows a better bone mineral density (see arrow in d2 vs. c2). Blank control group (a2) necrotic collapsed femoral head. Post operation first day: a1, b1, c1, d1. Pre-operation at twelfth week: a2, b2, c2, d2
