Straight forward cup position, leg length & offset
The THA cup and stem navigation workflow with APP reference provides focused functionality without an additional tracker fixed to the femur: Besides the cup position and orientation also leg length and offset changes are navigated and can be simulated. The results of the implantation can be simulated – before the final components are implanted. After attaching one reference marker to the pelvis prior to the dislocation and resection of the femoral head the initial anatomic situation is recorded by the palpation of defined landmarks. The result can be checked during stem preparation as well as after stem implantation. With the joint either reduced or dislocated.
