11.1 INTRODUCTION

Femoral shaft fractures are among the most severe injuries of the skeleton. In particular, these fractures are the
most serious of the long bones of the body, characterized by high morbidity and mortality [1, 2],and arefre-
quently associated with significant complications and sequelae. They represent around 13% of total skeleton
fractures [3].
For this reason, it is necessary that they are treated because of their complexity, seeking the most appropriate
method depending on the characteristics and location of the fracture (Fig. 11.1), as well as the patient. Although there
is no universally accepted classification, these fractures have been classified according to their location by Wiss et al. [4]
