Table 1_CT-based age-related trabecular redistribution in the proximal femur and its association with fracture patterns in elderly individuals with and without diabetes.docx

In our clinical work, we observed a phenomenon of trabecular redistribution in the proximal femur of older individuals. To investigate the distribution of bone trabeculae (compression and tension trabeculae) in the proximal femur, their changes with age, and their impact on fracture risk, we retrospectively analyzed hip computed tomography (CT) images and measured CT values in six different regions of the proximal femur: the primary compression trabecula, overlapping area, primary tension trabecula, secondary compression trabecula, the greater trochanter and lateral of primary tension trabecula.

With increasing age, the CT values in six regions decreased (p<0.01). The ratio of the primary compression trabecular area to the overlapping area remained relatively stable (F = 1.84, p=0.12), whereas the ratio of the primary tension trabecular area to the overlapping area decreased (F = 9.67, p<0.01). Elderly patients with proximal femoral fractures exhibited significant trabecular redistribution.
