Moreau-Costa-Bertani Internal Angle: How to perform

Last updated on July 6 2022

 

Description

The Moreau-Costa-Bertani angles can be used to perform an evaluation of longitudinal arch stability of the foot, on lateral radiographs. It is possible to measure the angulation between several foot structures, evaluate the foot arches and conclude about the occurrence of pes planus or pes cavus in the patient.

The internal angle is defined from the lines passing the sesamoid, the talonavicular and calcaneal tuberosity on the medial side.


Measurements

The measurements made by the procedure are displayed in the image:

  • Internal angle (MCBIA): the angle formed by the following lines:
    • Line formed from the lower point of the medial sesamoid to the lower point of the talonavicular joint;
    • Line formed from the lower point of the talonavicular joint to the lower point of the posterior calcaneal tuberosity.
