The chest x-ray is technically inadequate (rotated, under inspired). Within the limitations, one can see a deviated trachea to the left. Old chest x-ray images revealed a large retrosternal goitre.
Regarding the dislocated hip, this patient is an Anaesthetic risk for procedural sedation in ED.
While interpreting a chest x-ray, always look at tracheal anatomy to ensure there is no superior mediastinal mass causing deviation. Comparison with old chest x-rays are always helpful.
