3. Posicionamento do componente acetabular na artroplastia total do quadril com e sem o auxílio de um sistema de navegação computadorizado: estudo comparativo prospectivo randomizado / Acetabular component positioning in total hip arthroplasty with and without a computer-assisted system: a prospective, randomised and controlled study
Em um estudo prospectivo e randomizado sobre o posicionamento do componente acetabular na artroplastia total do quadril, 20 quadris foram operados com o auxílio da navegação livre de métodos de imagem e 20 quadris foram operados através do método convencional. Todas as cirurgias foram realizadas pelo mesmo cirurgião com o paciente em decúbito lateral

7. Computer-navigated Iliosacral Screw Insertion Reduces Malposition Rate and Radiation Exposure
Insertion of percutaneous iliosacral screws with fluoroscopic guidance is associated with a relatively high screw malposition rate and long radiation exposure. We asked whether radiation exposure was reduced and screw position improved in patients having percutaneous iliosacral screw insertion using computer-assisted navigation compared with patients having
