Proximal Femoral Morphometry: New Morphometric Parameters for Prediction Proximal Femoral Fracture

Understanding the morphometry of human skeleton is requisite in anatomical sciences and in the anticipation and management of femoral neck and trochanteric fractures. This study is aimed at developing proximal morphometric parameters that will conform to the biomechanical and anatomical features of the neck, proximal shaft (intertrochanteric or epiphyseal area) and shaft of the femur from radiographs of Nigerians. A total number of 1709 normal anteroposterior radiographs of the femur of Nigerians collected from Radiology Departments of selected Hospitals in Nigeria. From the obtained radiographs, angular parametric landmarks were measured utilizing standard instruments and protocols described in literatures. For males, mean±SEM values of FNSA, FNIA, FSIA and FIT are 132.38±0.310, 93.87±0.310, 39.21±0.210, 105.99±03.59mm2 and 131.96±0.26°, 92.87±0.29°, area 40.26±0.22°, 98.77±3.75mm2 for left and right sides of os femora respectively while for females, the mean+SEM values for the same parameters are 132.38±0.310, 93.87±0.31°, 39.21±0.210 79.62±3.13mm2 and 131.96+0.26°, 92.87+0.29°, 40.26±0.22°, 84.45±2.18mm2 for left and right sides of os femora respectively. The result obtained showed variation in FNSA with other populations. Also, the result showed the os femora as sexually dimorphic (p
