The heel tuberosity angle is the angle formed by the line from the highest point of the posterior articular surface of the heel to the highest point of the heel tuberosity and the anterior tuberosity, respectively, also known as the Bohler angle, with a positive length of 25°-40°. This angle is very important when resetting the heel fracture. In the process of heel fracture repositioning, the first is to restore the heel nodal angle, the second is to restore the heel cross angle, which is often referred to as the Gissane angle, and the second is to restore the axis of the root bone. In the process of heel repositioning, there is one line, that is, the force line; two angles, that is, the heel nodal angle and the heel cross angle; three surfaces, that is, the posterior heel articular surface, the anterior heel articular surface, and the heel dice articular surface; three degrees, that is, the width, height, and length of the heel bone. If these are mastered well, basically, the heel fracture can be reset with very satisfactory results.
