The objective of our study is to evaluate lower limb injuries in frontal crashes, identify the parameters that have significant influence on such injuries, and quantify their effect using logistic regression technique.

This paper contains a review of lower limb injuries literature. Later the data subset used for our study is described. It is followed by an exploratory analysis consisting of:​ The evaluation of lower limb injuries and the analysis of effects of different parameters on such injuries. The logistic regression analysis is presented in the end to quantify the effects of some significant factors on lower limb and leg-foot complex injury risk.

Two response measures, injury risk and average injuries per occupant, were analyzed during the exploratory analysis phase. Both measures showed similar effects of all factors.

Based on our logistic regression model, we have also predicted the probability of lower limb and leg-foot complex injury under certain conditions of intrusion, crash severity, seating position and gender.
