Hinge abduction occurs early in the fragmentation stage of Legg-Calvé-Perthes disease and should be suspected when abduction and internal rotation are lost. It can be confirmed by an AP radiograph in abduction and internal rotation in which the ossific nucleus is not covered by the acetabulum. An arthrogram can then yield greater information regarding the reversibility of the hinge abduction. Hinge abduction should be considered a contraindication to containment by redirectional pelvic or femoral varus osteotomy. However, good results have been reported with acetabular augmentation via shelf procedures or Chiari osteotomies. Valgus femoral osteotomies have also been beneficial in the treatment of the Legg-Calvé-Perthes hip with hinge abduction.
