Introduction: developmental dysplasia of the hip (DDH) is a common pediatric musculoskeletal disorder that includes a spectrum of abnormalities ranging from acetabular dysplasia to complete hip dislocation. Objective: to describe current information related to developmental dysplasia of the hip, including its etiology, classification, imaging findings, and management. Methodology: this review analyzed 32 articles, including review articles, original studies, and clinical case reports. From these, 21 references were selected based on their relevance to the objectives of the study. The databases used were PubMed, Google Scholar, and Cochrane Library. The search terms used in Spanish, Portuguese, and English included: developmental dysplasia of the hip, hip dysplasia, DDH, diagnosis, screening, and treatment. Results: early clinical screening and imaging evaluation, particularly ultrasound in infants, are essential for the timely diagnosis of DDH. Conservative treatment with the Pavlik harness shows high success rates in achieving stable hip reduction. Conclusions: early diagnosis and appropriate management are crucial to ensure normal hip development and prevent long-term complications.
