Developmental Hip Dysplasia

This is a patient who has progressively worsening range of motion of the right hip. Frontal and lateral radiographs of the hips were obtained which demonstrate superolateral dislocation of the right femoral head out of the acetabulum. The right acetabulum is markedly shallow compared to the left as indicated by the red arrow. Findings are consistent with developmental hip dysplasia. Addtionally, both femoral necks are abnormally straightened which is referred to as coxa valga. The patient has shunt tubing from a ventriculoperitoneal catheter in his abdomen.
