[Method not stirrups--treating DDH according to Pavlik]

Abstract

Developmental dysplasia of the hip (DDH), previously termed "congenital dislocation of the hip" (CDH), encompasses a group of related pediatric disorders, some diagnosed soon after birth or later. These include clinical instability of the hip, with or without anatomical dysplasia, subluxation or dislocation. These days, such disorders are usually diagnosed soon after birth, and can develop to normal or worsen to severe disability in time. Most of the hips are not dislocated but all pathological hips show some degree of dysplasia and a minority is dislocated. The keystone to successful treatment of DDH is early diagnosis. Screening is successful only if followed by correct early treatment. Various methods and devices have been proposed for the treatment of DDH. After closed reduction of the hip is done, sometimes with violence, rigid fixation might cause avascular necrosis of the femoral head (AVN). These methods are used less and less, having been replaced by Pavliks method, whereby, if strictly used, the AVN rates are almost zero.
