Transcondylar femoral axis

  • Acronym: TCA

Definition

Stephan Mahler

The transcondylar 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 transcondylar 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 transcondylar axis is drawn by connecting the most caudal aspects of the medial condyle and lateral condyle of the femur.
