After inserting the guidewire along the outline displayed on the ADAPT monitor, the predicted position and length of the lag screw are displayed in a setting where the TSD is 5 mm. When the lag screw is actually inserted, the display shows how many more mm it needs to be inserted before the TSD will be in the 5 mm position. In addition, TAD can be checked at any time during the operation. After the lag screw has been installed, the position of the lag screw is displayed in 3D.
