Table 2.
Comparing BMD differences between 29 patients with neck fractures and 8 patients with trochanteric fractures. For patients with trochanteric fractures, the average BMDs in the femoral neck and the trochanter were both lower. However, neither differed significantly (with p-values of 0.661 and 0.649, respectively). From the SPM-based comparison, we selected two sub-regions, one near the femoral neck and the femoral head (ROI I, as indicated by arrow I in Fig. 7B), and the other in the internal calcar septum (ROI II, as indicated by arrow II in Fig. 7B). The average BMDs in these two regions were calculated, and the differences between the two fracture types were statistically significant (with p-values of 0.014 and 0.006, respectively).
