The present study of 55 dysplastic hips that were treated with a periacetabular osteotomy confirms previous data showing that the dGEMRIC index correlates with clinically relevant parameters, such as pain and joint space width. Moreover, a low preoperative dGEMRIC index was shown to predicta a poor surgical outcome, i.e., total joint replacement within four years post-surgery. The study also shows that the analysis of one central slice over the hip joint provides similar information as a multislice protocol including most joint cartilage. We conclude that a single-slice dGEMRIC protocol can be used to identify dysplasia patients who could benefit from surgery.
