Table 1 Quality of postoperative reduction

From: Risk factors for implant failure in reverse oblique and transverse intertrochanteric fractures treated with proximal femoral nail antirotation (PFNA)

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
