From: New tip-apex distance and calcar-referenced tip-apex distance cut-offs may be the best predictors for cut-out risk after intramedullary fixation of proximal femur fractures

Figure 1

(A) Tip-apex distance calculated on anteroposterior radiograph (TAD ap); (B) Tip-apex distance as referenced to the calcar calculated on the anteroposterior radiograph (CalTAD ap); (C) Tip-apex distance calculated on the lateral radiograph (TAD lat); (D) Tip-apex distance (TAD); (E) Calcar-referenced tipapex distance (CalTAD). D true is the known diameter of the lag-screw (10.5 mm for Gamma3 nail, 15.5 mm for Trigen Intertan nail). D ap is the calculated diameter of the lag-screw on the anteroposterior radiograph. D lat is the calculated diameter of the lag-screw on the lateral radiograph.
