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
- costochondral junctions are more angular with sharper step-offs (scorbutic rosary)
- sternum is usually depressed
- hypophosphatasia
- chondrodystrophy
- healing fractures as a result of non-accidental injury in children: important to consider as an alternative explanation
