This study includes treatment with a Pavlik harness or other device.Although there are many obstacles for closed reduction and hip spica cast application for cases of developmental dysplasia of the hip in older child, still we can achieve satisfactory results in properly selected cases which must be observed carefully until skeletal maturity. The orthopedic surgeon must be aware of the possible complications either early or late and should not hesitate to perform appropriate secondary procedures depending on the development of the hip joint after reduction during the follow up period.
