Ligamentoplasty of Ligamentum Tere Developmental Dysplasia of the Hip

The hip is formed by the acetabulum, the proximal femur and soft tissues joining them (capsule, teres ligament, transverse ligament and pulvinar). The acetabulum is a complex structure in the growing child. It is formed by the joined pubis, This junction is called tri radiate cartilage, which is responsible for acetabular growth. The external surface of the acetabulum is covered by a horse shoe-shaped articular cartilage. The transverse ligament joins both extremes of the articular cartilage inferiorly.
