H: Hilgenreiner’s line

P: Perkin’s line 

Both femoral heads are in the superolateral quadrant.

There is severe dysplasia of the acetabula with marked increased in acetabular angles. Also note lack of ossification of the femoral capital epiphyses which is clearly abnormal for his age.

Case Discussion

Developmental dysplasia of the hip (DDH) is a developmental disorder affecting the proximal femur and acetabulum that leads to hip laxity, sublaxation or dislocation. Early diagnosis and treatment is important. Abnormal development of the hip includes the osseous structures, such as the acetabulum and the proximal femur, and the labrum, capsule, and other soft tissues.
