Technical Note on Using Intraoperative Smartphone Applications to Adjust Cup Inclination Angle during Total Hip Arthroplasty (THA)

Acetabular cup optimum position is paramount for total hip arthroplasty (THA) good outcomes. Although controversial,Lewinnek proposed safe zone for cup placement still the most widely accepted target. Cup placement can be improvedusing specific anatomical landmarks, computer navigation system and handheld navigation devices. As using asmartphone on daily bases became popular among orthopedic surgeons, in this technical note, we describe how to usesmartphone specific applications intraoperatively during total hip arthroplasty to adjust cup inclination angle, which webelieve to be easy, cheap and beneficial for young less experienced surgeons.Level of evidence: IV
