Prominence of the costochondral junction can be seen in a number of conditions:
-
rickets: Nodularity at costochondral junction (rachitic rosary)
-
scurvy: The costochondral junction is more angular and has a sharper step-off (scorbutic rosary). The sternum is usually found to be depressed.
- chondrodystrophy
Appearances in this case most likely represent rickets.
