Developmental dysplasia of the hip (DDH) or dislocation is a disease which affects the growth or stability of the hip joint before and during the critical growth period after birth. The main goal in the treatment of DDH is to prevent the continuation of the pathology in the joint by concentric reduction of the hip joint and to provide an appropriate environment for the development of the proximal femur and acetabulum. The most preferred treatment in the DDH under one year of age is closed reduction. Open reduction is preferred if the hip joint cannot be reduced concentrically without forcing with closed methods and if the medial contrast agent pooling is >6 mm in arthrography. The aim is to intervene in extracapsular and/or intracapsular pathologies that prevent reduction. The medial approach is preferred in children younger than 12 months of age who require open reduction, and the anterior approach that allows capsulorrhaphy is preferred if the child is older than 12 months. Medial approach for open reduction is preferred by many surgeons due to its advantages such as minimal dissection, minimal blood loss, bilateral application and better cosmetic incision result. However limited visibility of the hip, risk of medial circumflex artery injury, and inability to perform capsulorrhaphy are disadvantages. The choice of the medial or anterior approach is also related to the presence of ligamentous laxity, the age of the patient and the experience of the surgeon.
