Current status of the diagnosis of developmental dysplasia of the hips in the 21st Century

Inspired by an article on developmental dysplasia of the hips (DDH) written in the mid-20 th century, we present an updated analysis of the epidemiology, etiology, risk factors, and natural history of this condition.We summarize the fundamental concepts and definitions necessary to come up with an adequate diagnosis.We examine the role of imaging in the diagnosis, highlighting the AP (anteroposterior) pelvic radiograph, the most used method in our country for this purpose.We describe the method we have developed, called HI-RADS, to analyze and report AP pelvic X-rays in the context of universal screening at three months.We address the various ultrasound techniques available for diagnosis, recommending the combined use of static and dynamic approaches.We emphasize the importance of early detection to prevent complications, a practice that is carried out in several countries, although there is still a lack of consensus regarding its implementation.
