    ABSTRACT: To determine whether the presence of bone bars (BB) identified on anteroposterior hip radiographs are more prevalent in patients that have had a hip fracture as compared to patients without a fracture. Ninety-two Caucasian women with a unilateral proximal femur fracture were retrospectively evaluated and randomly selected using radiology database records to comprise the investigational group. Ninety-eight age-matched Caucasian women without hip fracture were selected as a control group. Anteroposterior hip radiographs were evaluated for the presence of BBs by two musculoskeletal radiologists. Chi-square tests were used to assess whether fractures were more prevalent in patients with BB than those without BB. The patient population was comprised Caucasian women with a mean age of 79.8 ± 6.4 years in the control group and 79.9 ± 6.6 years in the investigational group. Regardless of the reader, BB were identified in a significantly higher percentage of women with a fracture (75 versus 39%, p < 0.001 or 53 versus 38%, p = 0.041) as compared to those without a fracture. BB are associated with hip fracture. Their presence is a trigger for requesting a dual-energy x-ray absorptiometry (DXA) examination to confirm or refute a diagnosis of low bone mineral density (BMD) and a subsequent increased risk of fracture.
