Accuracy of a portable accelerometerbased navigation system for cup placement and intraoperative leg length measurement in total hip arthroplasty: A cross-sectional study

Complications after total hip arthroplasty (THA) are frequently the consequence of malpositioned components or leg length discrepancy after surgery. Recently, a new version of a portable, accelerometer-based hip navigation system (New HipAlign) was made available with a change in the method of measuring cup abduction and the addition of a leg length measurement function.
