THAplus provides full functionality without femoral pin. The newly developed OrthoPilot® THAplus module provides focused functionality: Besides the cup position also leg length difference and offset of the stem implant are navigated and can be simulated. Without any invasive reference marker at the femur. After attaching one reference marker to the pelvis prior to the dislocation and resection of the femoral head the initial anatomic situation is recorded.
The result can be checked during stem preparation as well as after stem implantation. With the joint either reduced or dislocated!
