Clinical Features and Outcomes of Bilateral Atypical Femoral Fractures

Figure 3

(a) The patient suffered a subtrochanteric AFF on the left side by sprain. At that time, the right femoral roentgenogram showed periosteal thickening of the lateral cortex at the subtrochanter (circle; see magnification). (b) Periosteal thickening of the lateral cortex progressed to incomplete fracture (circle; see magnification). (c) Incomplete fracture progressed to complete fracture by falling. (d) Complete bone unions were achieved on the left and right sides at 58 and 25 months after the surgery, respectively.
