ABSTRACT
This article reviews the various studies of MRI in developmental dysplasia of the hip (DDH), focusing on the research progress of MRI in evaluating the developmental trend of hip joint after DDH closed reduction, in order to find reliable indicators for predicting the development of the hip joint after closed reduction of DDH. Due to the advantages of MRI in identifying cartilage and soft tissue, more and more studies have performed MRI before and after DDH treatment to evaluate its specific role. This article has made a corresponding summary, for example, using MRI to identify obstacles that affect the reduction of dislocated hip joints such as fibrofatty tissue hyperplasia/thickening, joint effusion, labrum inversion, iliopsoas muscle atrophy, etc; using MRI to observe the cartilage shaping of the femoral head before and after closed reduction treatment of DDH; using MRI to verify the validity of intraoperative arthrography in assessing the position of femoral head and socket or directly observe the relationship of femoral head and socket with MRI; using hip MR angiography to evaluate the acetabular labrum injury in DDH patients. In addition, the results of bias-corrected studies on MRI-assessed hip-related observations are also summarized. In general, the application of MRI in the diagnosis and treatment of DDH is becoming more and more mature and perfect, and has been advocated by many scholars as a routine auxiliary examination for DDH. However, there is still no consensus on how to evaluate and predict the developmental outcome of the hip joint after closed reduction of DDH. This article summarizes the current progress from three aspects. We summarize the results of many measurements on MRI, which represent cartilage acetabular coverage and are used to predict acetabular growth and development; the research results on the use of MRI to explore the impact of the labrum on the development of the hip joint are summarized; the related research results of MRI evaluation of avascular necrosis of the femoral head after closed reduction are summarized. The above content can provide some reference for the current clinical work and research.
