Hip ultrasound

Abstract

Sonography has been widely utilized for several decades in the diagnosis and follow-up of developmental dysplasia of the hip due to its ability to visualize the nonossified femoral head and portions of the acetabulum in neonates, dynamic capabilities, accuracy, and lack of nonionizing radiation. Furthermore, hip sonography is also used throughout parts of the world to diagnose and guide intervention for both children and adults. The hip joint, tendons, and periarticular structures can be delineated with sonography in a variety of congenital, developmental, infectious, inflammatory, arthritic, traumatic, and neoplastic disorders. The following discussion focuses on the sonographic technique and imaging characteristics of congenital and developmental anomalies of the hip in children, as well as the sonographic evaluation of the hip joint and tendons.
