1. Alignment [13] | |
a. Anteroposterior view: normal or slightly valgus neck-shaft angle | |
b. Lateral view: less than 20 degrees of angulation | |
2. Displacement of main fragments [14] | |
a. Anteroposterior view: displacement less than the medial cortical thickness | |
b. Lateral view: displacement less than the anterior cortical thickness | |
Good, both criteria of alignment and both criteria of displacement | |
Acceptable, both criteria of alignment and only one criterion of displacement | |
Poor, only one or neither criterion of alignment or neither criterion of displacement |
