Although the physiopathology behind the Legg-Calvé- Perthes disease (LCPD) has been studied extensively, there is little agreement on the treatment protocol. The main target of the treatment in LCPD is to provide congruency of the femoral head and acetabulum. It is estimated that, as long as the femoral head is inside acetabulum the roundness of the femoral head will be ensured. To achieve this compliance, different conservative and surgical treatments are applied. One of the main conservative treatment option is brace treatment. Different types of braces have been utilized besides hip abduction, all of which aim to centralize the femoral head inside the hip joint. The literature lacks comparative studies on the effectiveness of brace treatment in LCPD. The studies on Catterall III/IV and Herring type C where the involvement of the femoral head is severe, indicates that the results are poor with the brace treatment. Although more favorable results can be obtained with brace treatment in younger patients (<6 years) and in patients with less severe head involvement, the results are similar to other conservative treatments. On the other hand, brace treatment is cheap, causes no surgical scar and radiation exposure is less than the other treatments. With these advantages brace treatment is still an option as a conservative treatment method in selected patients.
