Setting the inclination for acetabular reaming in total hip replacement: Should we return to Charnley’s original method? A theoretical X-ray study

Abstract

Being one of the most successful surgeries in the history of medicine, the indication for total hip arthroplasty have widened and are increasingly being offered to younger and fitter patients. This has also lead to high expectations for longevity and outcomes. Acetabular cup position has a significant impact on the results of hip Arthroplasty. We suggest that guiding of acetabular reamers using Charnley’s method offers the potential for placing the cup at the optimum 45 degree angle. Further work is currently underway using Pelvic CT scans with 3D reconstruction to correlate acetabulum anteversion angle.
