Illustration of the main fracture zone, the extension zone, and the exclusion zones. All fractures must involve the main fracture zone. Fractures can extend to the proximal extension zone, if minimal displaced within the extension zone. Fractures cannot involve the exclusion zones or be displaced within the extension zone. The proximal square is obtained by measuring the widest part of the segment, then measuring the same length from the apex of the proximal segment through the axis of the proximal humerus, this endpoint separates the proximal humerus from diaphysis. The distal square is obtained by measuring the widest part of the segment, then measuring the same length from the most distal part of the trochlea through the axis of the distal humerus, this endpoint separates the distal humerus from the diaphysis
