Figure 6

False negative (CTRA-/Fx+) (Case 5, L femur). (a) This is a 63-year-old male with metastatic renal cell carcinoma in the distal femoral diaphysis. (b) CTRA did not predict fracture in this patient, and FEA was not conducted due to the distal nature of this lesion. (c) The subject had a fall resulting in a fracture of the left femur and (d) underwent operative fixation.
