Is the cup orientation different in bilateral total hip arthroplasty with right-handed surgeons using posterolateral approach?

摘要

BackgroundThe impact of surgeon handedness on acetabular cup orientation in total hip arthroplasty (THA) is not well studied. The aim of our study is to investigate the difference of cup orientation in bilateral THA performed by right-handed surgeons using posterolateral approach and which cup could be fitter to Lewinneck’s safe zone.
