Acetabular Cup Navigation with theVectorVision System

Despite technical improvements misplacement of implants leading to complications like dislocation or loosening [2, 3] are still observed in total hip arthroplasty (THA). Especially correct anteversion of the cup can prove difficult if the operating table is used as the only reference level regarding pelvic tilt. Computed tomography (CT) allows for three-dimensional reconstruction of individual pelvic and femoral anatomy providing basic information for modern navigation systems. The navigation system VectorVision has been employed in our hospital since the year 2000. Soft- and hardware are currently the phase VectorVision hip 2.0.
