The Importance of Length of the Cephalomedullary Nails for Fixation of the Proximal Femoral Fractures: An Educational Corner

Fractures of the proximal femur (Figure 1) are the third most common fracture type in the general population and one of the most common age-related fractures in the elderly (1). Although there are many fixation methods for trochanteric fractures, the intramedullary nail (IMN) has been routinely used (2-9). Among the IMN devices, the proximal femoral nail antirotation (PFNA) is highly preferred, because it has the advantageous biomechanical design of the IMNs, while the helical blade design has increased its fixation stability.
