Influence of Age on Trauma Femoral Fractures

This study aimed to determine the influence of ageing on the incidence and site of femoral fractures in trauma patients, by taking the sex, body weight, and trauma mechanisms into account.

This retrospective study reviewed data from adult trauma patients aged ≥ 20 years who were admitted into a Level I trauma center, between January 1, 2009 and December 31, 2016. According to the femoral fracture locations, 3859 adult patients with 4011 fracture sites were grouped into five subgroups: proximal type A (n = 1,359), proximal type B (n= 1,487), proximal type C (n = 59), femoral shaft (n = 640), and distal femur (n = 466) groups. A multivariate logistic regression analysis was applied to identify independent effects of the univariate predictive variables on the occurrence of fracture at a specific site. The propensity score accounts for the risk of a fracture at a specific femoral site was calculated and presented visually with age in a two-dimensional plot.
