[Closed reduction in the treatment of developmental dysplasia of the hip].

One of the standard treatment methods for developmental dysplasia of the hip is closed reduction followed by immobilization in a hip spica cast. This treatment is performed before achievement of independent walking, under general anesthesia and with arthrographic control. Avoidance of forced reductions and immobilization of the hip with extreme positions is of utmost importance during the procedure. Development of avascular necrosis (AVN) of the femur head is the main parameter affecting the late outcome of the procedure. All modifiable factors should be influenced in favor of the patient to avoid AVN. This method appears to be satisfying with acceptable rates of AVN when applied by experienced pediatric orthopedic surgeons.
