Ultrasound is a highly economical, portable, and accessible method that has significantly advanced as a diagnostic tool since its first application in clinical practice by Austrian neurologist Karl Dussik (1908-1968). It allows for close interaction between the operator and the patient, facilitating the identification of specific areas or movements that provoke symptoms. Ultrasound is particularly beneficial for pediatric patients, as it enables examinations without the need for sedation or separation from parents, unlike MRI scans. Modern high-resolution ultrasound machines provide detailed visualization of musculoskeletal structures and pathologies. This study focuses on the depiction of musculoskeletal conditions affecting large joints, which are increasingly becoming the subject of ultrasound examinations. Additionally, the study explores the use of ultrasound for screening pediatric populations for developmental hip disorders. Promising techniques such as sonoelastography and ultrasound contrast agents are highlighted as potential tools in the diagnosis of various musculoskeletal diseases. However, it is important to acknowledge the limitations of ultrasound. Ultrasound waves have limited penetration into bones, joints, and deep structures. Accurate interpretation requires extensive knowledge of anatomy and pathology. While MRI remains the method of choice for diagnosing most musculoskeletal conditions, ultrasound has demonstrated its practicality and value as an adjunctive tool.
