| Rachitic rosary on chest radiograph |
The prominent knobs of bone at the costochondral joints of rickets patients are known as a rachitic rosary or beading of the ribs. The knobs create the appearance of large beads under the skin of the rib cage, hence the name by analogy with the beads of a Catholic Christian rosary.[1]
Causes
[edit]Causes include:[2]
- Rickets : Nodularity at costochondral junction (rachitic rosary).
- Scurvy : More angular costochondral junction with a sharper step-off (scorbutic rosary) and depressed sternum.
- Chondrodystrophy
Pathophysiology
[edit]Rachitic rosary is due to a deficiency of calcium resulting in lack of mineralization and an overgrowth of costochondral joint cartilage. The calcium deficiency may be caused by rickets or other causes of calcium deficiency such as hypoparathyroidism.[3]
Diagnosis
[edit]Palpation ( Beads formation), on chest X-ray

The earliest bone lesion that we find in incipient rickets is the beading of the ribs, the so-called rachitic rosary. This is due to an enlargement of the osteo chondric articulations, and hence its name because of fancied resemblance to the rosary used by the Catholic worshiper.
