Abstract
To determine whether simple measurements made on conventional radiogra phs of the hip could predict hip fractures, we obtained pelvic radiogr aphs on 9704 white women age 65 or older. We analyzed the radiographs of all 162 women who subsequently suffered a hip fracture and 162 rand omly selected women who did not. Adjusting for age, four measurements independently predicted hip fracture: reduced thickness of the femoral shaft cortex (odds ratio 1.7 per standard deviation; 95% confidence i nterval 1.2, 2.3) and of the femoral neck cortex (1.4 per standard dev iation; 1.0, 1.9), reduction in an index of tensile trabeculae (2.0 pe r unit; 1.4, 2.9), and wider trochanteric region (1.4 per standard dev iation; 1.0, 2.0). The combination of these four measurements predicte d hip fracture at least as strongly as did measurement of bone density of the femoral neck (areas of the receiver-operating characteristic c urve = 0.81 and 0.80, respectively). We conclude that simple measureme nts made on pelvic radiographs predict hip fractures as well as bone d ensity of the hip.
