| ==Overview==
| |
| Rickets is a bony disease due to decreased [[mineralization]] of [[growth plate]], associated with abnormal serum calcium and phosphate level<ref name="pmid23208530">{{cite journal| author=Shore RM, Chesney RW| title=Rickets: Part I. | journal=Pediatr Radiol | year= 2013 | volume= 43 | issue= 2 | pages= 140-51 | pmid=23208530 | doi=10.1007/s00247-012-2532-x | pmc= | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=23208530 }} </ref>. This leads to softening of bones.Rickets is more common in children especially in developing countries due to malnutrition and famines. It can also occur in adults and similar presentation in adults is termed as [[osteomalacia]].

| The origin of the word "rickets" is unknown. The Greek derived word "rachitis" (meaning "inflammation of the spine") was later adopted as the scientific term for rickets, due chiefly to the words' similarity in sound.

| ==Historical Perspective==
| |
| | |
| ==Classification==
| |
| There are 3 types of rickets
| |
| # Nutritional Rickets (due to deficiency of Vit D, calcium, and phosphorous)
| |
| # Vitamin D dependent rickets (due to defective metabolism of vitamin D)
| |
| # Vitamin D resistant rickets (hypophosphatemic rickets due renal phosphate wasting)
