Its success rate is high and complication rate is low, so long as the lag screw is carefully placed. Baumgaertner devised the concept of (TAD). This measurement, in millimeters, is the sum of the distances from the tip of the lag screw to the apex of the femoral head on both the AP and lateral radiographic views and it should be <25mm to minimize the risk of lag screw cutout UR - http://172.23.153.220/th.pdf ER -
