Developmental Dysplasia of the Hip (Pediatric)

Developmental Dysplasia of the Hip (DDH) that requires treatment affects 2-3 infants per 1,000 born. For proper development of the infantile hip, the femoral head of the hip (or ball) must be located deep within the acetabulum (or cup). If the ball is out of the cup, the hip is dislocated. If the hip is in a shallow cup, the hip is dysplastic (under developed).



DDH ranges from dysplasia to dislocation. Clinical examination of the newborn hip can determine if excessive laxity of the hip is present and determine the position of the ball and the cup. An ultrasound may be necessary to evaluate the development of the cartilaginous hip joint early and X-rays later. Early identification of DDH allows for brace treatment with a Pavlick Harness. Later diagnosis may require surgery. Please refer to for more information.
