Figure 3

True positive (CTRA+/Fx+) (Case 2, R femur). (a) This is a 77-year-old female with metastatic renal cell carcinoma to the right femoral diaphysis. (b) CTRA and FEA both predicted fracture for this subject. (c) The patient was admitted to the hospital on the day of her initial appointment and twisted her leg in bed, likely causing a fracture. When taken to the OR for prophylactic stabilization, the patient was noted to have a fracture and thus was treated with ORIF.
