We evaluated bone atrophy in 79 female patients with femoral neck fractures (45 trochanteric, 34 cervical) and 47 healthy female controls by radiographic morphometry. On the femoral radiographs, the following measurements were taken: Singh index; width of the calcar femorale just above the lesser trochanter; lateral cortical width (FTCW) near the level of the lesser trochanter; total width (FTW) and cortical width (FCW) at the midshaft of the femur, where the cortical width was maximal; and the ratio (FCW/FTW) of cortical width to total width at the midshaft of the femur.
There was no significant difference in Singh index between the three groups. Width of calcar femorale, FTCW, FCW and FCW/FTW were significantly lower in two fracture groups than in controls. There was no significant difference in all measurements between two fracture groups. However, using multiple linear regression analysis, calcar femorale width, Singh index and FCW/FTW were significant in trochanteric fracture patients and only calcar femorale width was significant in cervical fractures.
