We aimed to determine the novel indicators of the high-risk vertical range and axial angle for deep femoral artery injury that can be easily confirmed intraoperatively using fluoroscopy for hip fracture.\n\nMethods: In a single hospital, the lower extremity computed tomography angiographies of 88 patients (50 men and 38 women) were analyzed. A reference plane was defined as the femoral neck and shaft on the same straight line in the lateral view. Reference points were the lower end of the lesser trochanter and distal femur at 140 mm from the tip of the greater trochanter. To determine the high-risk angle for deep femoral artery injury based on the reference plane, the angle from the reference plane to the deep femoral artery (bone\u2013arterial angle) and the shortest distance between the surfaces of the femur and the deep femoral artery (bone\u2013artery distance) were measured at the lesser trochanter and the greater trochanter. We analyzed the bone\u2013arterial angle and bone\u2013artery distance values, their differences among the sexes, and their correlation with body height and body weight.\n\nResults: Overall, in the lesser trochanter, the mean bone\u2013arterial angle and bone\u2013artery distance were 19.2\u00b0 \u00b1 8.0\u00b0 and 22.9 \u00b1 4.7 mm, respectively. In the greater trochanter, the mean bone\u2013arterial angle and bone\u2013artery distance were \u201333.9\u00b0 \u00b1 17.0\u00b0 and 11.3 \u00b1 4.1 mm, respectively. The mean bone\u2013artery distance of the lesser trochanter was significantly longer in men than in women (24.1 \u00b1 4.5 mm and 21.4 \u00b1 4.5 mm, respectively, P &lt; 0.01), and for the lesser trochanter, positive correlations were found between body height and both bone\u2013 arterial angle and bone\u2013artery distance (r=0.373, P &lt; 0.001; and r=0.456, P &lt; 0.0001, respectively), with body weight and bone\u2013artery distance positively correlated (r=0.367, P &lt; 0.001). At the greater trochanter, there were negative correlations between body height and bone\u2013arterial angle (r=\u20130.5671, P &lt; 0.0001), body weight, and bone\u2013arterial angle (r=\u20130.338, P &lt; 0.01).\n\nConclusion: The knowledge of our reference plane and high-risk angles and distances allows surgeons to minimize the risk of deep femoral artery injury. These are easily confirmed intraoperatively using fluoroscopy, allowing surgeons to avoid maneuvering in the deep femoral artery range.\n\nLevel of Evidence: Level IV, Diagnostic Study\n\nCite this article as: Kaneoka T, Imagama T, Yamamoto M.
