As it is assumed that weight-bearing stress leads to collapse of the epiphysis, for several years, weight relief had previously been advocated. Despite this practice, there is no evidence that weight relief alone prevents epiphyseal collapse. However, there is some clinical and experimental evidence that if weight relief is combined with other forms of treatment it may be beneficial. Containment attempts to ensure that weight- bearing and muscular forces are not imparted from the acetabular margin onto the anterolateral part of the avascular epiphysis that is most vulnerable to deformation during the early stages of the disease process. There are two strategies for containment; the first is to keep the hip effectively abducted and internally rotated (or abducted and flexed) either by bracing, casting, or femoral osteotomy thereby ensuring that the anterolateral part of the femoral head is positioned well within the acetabulum. The second is to either reorient the acetabulum by a peri acetabular osteotomy or augment the acetabulum by a shelf acetabuloplasty so that anterolateral part of the femoral head is well covered by the realigned acetabulum or by the newly created “shelf”. The factors that need to be considered while planning treatment in the early in the course of the disease are the age of the child at onset of the disease, the extent of epiphyseal avascularity and the presence or absence of femoral head extrusion. The prognosis is very good in children in whom less than half the epiphysis is infracted and consequently they may be treated symptomatically . The prognosis is good in young children (under 8 years of age at the onset); they do well even if more than half the epiphysis is avascular as long as they do not develop extrusion. If extrusion occurs, containment is warranted. In short, containment may not be required in two groups of children; first, young children with mild disease and no extrusion and second, children who will not benefit from it because it is too late
