Hip arthroplasty after pelvic and femoral osteotomies

Pelvic and femoral osteotomies can be achallenge even for experienced orthopedic surgeons. Residual metal may complicate the insertion of the endoprosthesis in some cases. Sometimes, the anatomical modification of the previous osteotomy complicates the total hip replacement. This may require the use of an acetabular revision system for the primary implantation. Femoral deformities can require additional osteotomies of the femur during the implantation. In every case, accurate preoperative planning should be performed. Apreoperative CT with 3D reconstruction is apowerful tool for further information beyond conventional imaging.
