Fracture of the femoral neck: optimal screw position and bone density determined by computer tomography

The bone density of five proximal femurs from female cadavers was measured with computed tomography using a pixel size of 1.2 mm. A three dimensional reconstruction was performed along four well-defined axes. The region of maximal relative bone density correlated well with a previous report of the optimal position of a screw when treating a fracture of the femoral neck.
