Abstract

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 improved
using specific anatomical landmarks, computer navigation system and handheld navigation devices. As using a
smartphone on daily bases became popular among orthopedic surgeons, in this technical note, we describe how to use
smartphone specific applications intraoperatively during total hip arthroplasty to adjust cup inclination angle, which we
believe to be easy, cheap and beneficial for young less experienced surgeons.
Level of evidence: IV
