Abstract:
Due to the fact that the articular cartilage of children's joints has not yet been fully ossified, visualizing the adjacent anatomical structures during the clinical diagnosis and treatment of joint diseases and injuries in children is a challenging issue. Arthrography is an efficient, convenient, and minimally invasive technique, and is particularly crucial for the visualization of children's hip joints. Currently, arthrography technology is widely employed during surgeries for developmental dysplasia of the hip (DDH), and in recent years, numerous studies have concentrated on the efficacy of joint angiography, exploring its assessment and predictive roles during and after the operation. We review the overview of hip joint arthrography techniques, such as the concept of arthrography, the selection of access routes for hip joint arthrography, the process of hip joint arthrography, the dosage and operation of contrast agents, and the adverse reactions of contrast agents; the use of hip joint arthrography to evaluate the quality of closed reduction; the use of hip joint arthrography to predict the future development and outcome of the acetabulum after closed reduction; the use of hip joint arthrography in the study of open reduction or osteotomy; the use of hip joint arthrography to observe the morphology of soft tissues in the hip joint; the use of hip joint arthrography in combination with nuclear magnetic resonance to observe the anatomical structure of the acetabular labrum. Summarizing the research results of arthrography for evaluating the corresponding indicators of the hip joint helps improve the matching between the femoral head and the acetabulum and the accuracy of evaluating the quality of reduction, uncovers identifying factors such as labrum varus that hinder concentric reduction, enhances the ability to predict the development and outcome of the acetabulum, and has significant guiding significance for the precise selection of the timing of surgical intervention for early and residual deformities in children with DDH. Exploring the application of arthrography technology in evaluating the quality of closed reduction in DDH and predicting the development of the acetabulum after reduction is expected to provide meaningful references for orthopedic surgeons in the current clinical diagnosis, treatment, and research of DDH.
