Figure 1.

Anterior, posterior, and lateral x-ray images of full length of the injured femur during & after two months surgery with femoral anatomical specificity of antecurvation. (A) Full-length anteroposterior X-ray image of the injured femur during the operation. (B) Full-length anteroposterior X-ray image of the injured femur two months after surgery. (C) Full-length lateral X-ray image of the injured femur during the operation. (D) Full-length lateral X-ray image of the injured femur two months after surgery. (E) If the patient has the anatomical specificity of lateral curvation of the femoral shaft, resistance will be encountered while implanting the nail at the routine entry point. (F) Accordingly, the entry point should shift to the lateral. (H) If the patient has the anatomical specificity of antecurvation of the femoral shaft, resistance will be encountered while implanting the nail at the routine entry point. (G) Accordingly, the entry point should shift forward.
