Palpable knobs on the chest wall.

Patient Data

Age: Infant
Gender: Male

Widening of the anterior rib ends at the costochondral junctions.

Case Discussion

Rachitic rosary is most frequently seen in rickets (which is the diagnosis in this case)

Differential diagnosis

Other causes of this appearance include: 

  • scurvy
    • the costochondral junction is more angular and has a sharper step-off (scorbutic rosary). 
    • the sternum is usually found to be depressed.
  • hypophosphatasia
  • chondrodystrophy
  • healing fractures as a result of non-accidental injury in children: important to consider as an alternative explanation.
