Intertrochanteric axis

  • Acronym: ITA

Definition

Stephan Mahler

The intertrochanteric axis is a landmark used to assess angular deformities of the femur and provide guidance for corrections. It is used to determine the femoral trochanteric angle. The intertrochanteric axis is determined from multiplanar reconstructed CT images of the femur. A transverse plane is used to visualize the entire diaphysis of the femur as a straight cylinder by scrolling through sequential images.

The intertrochanteric axis is drawn connecting the most prominent aspect of the greater trochanter (i.e. the lateral part of the greater trochanter) and the most prominent aspect of the lesser trochanter.
