Editorial Commentary: Differences in Femoral Torsion Measurements Based on Axial Versus Axial–Oblique Magnetic Resonance Imaging Sequences—Let's Begin to Standardize Hip-Preservation Techniques to Improve Research and Clinical Outcomes

摘要

? 2021 Arthroscopy Association of North AmericaFemoral torsion is an important measure in patients with femoroacetabular impingement presenting with limited hip range of motion. However, femoral torsion may be measured using computed tomography or magnetic resonance imaging and on axial or axial–oblique sequences. Recent research shows that femoral torsion measurements differ based on the magnetic resonance imaging sequences on which this parameter is measured. In some cases, this may be clinically relevant in the sense that a derotational femoral osteotomy may be considered when otherwise it would not be. As more research is published within the specialized field of hip preservation surgery, we must begin to standardize our research and clinical techniques such that outcomes may be appropriately compared across studies.
