Assessment of Acetabular Component Anteversion Following Total Hip Arthroplasty: Current Imaging Techniques and Limitations

The authors aim to evaluate the various imaging techniques used to measure acetabular component anteversion following total hip arthroplasty (THA) and their respective limitations. They highlight that while radiographs are commonly used for assessing acetabular position, CT scans may offer greater accuracy and reproducibility, particularly when the entire pelvis is imaged. Understanding the strengths and weaknesses of these methods is crucial for addressing complications such as instability and pain after THA.
