Femur First navigation can reduce impingement severity compared to traditional free hand total hip arthroplasty

Abstract Impingement is a major source of dislocation and aseptic loosening in total hip arthroplasty (THA). We compared impingement free range of motion (ROM) using a novel computer navigated femur first approach to conventional THA. In addition, impingement between genders was also explored. In a...
