===Differential diagnosis===
[[Osteochondrodysplasias]], also known as genetic bone diseases, may mimic the clinical picture of rickets in regard to the features of bone deformities.<ref name=elsobky2017>{{cite journal| vauthors = El-Sobky TA, Shawky RM, Sakr HM, Elsayed SM, Elsayed NS, Ragheb SG, Gamal R |title=A systematized approach to radiographic assessment of commonly seen genetic bone diseases in children: A pictorial review.|journal= J Musculoskelet Surg Res|volume=1|issue=2|pages=25|date=15 November 2017|doi=10.4103/jmsr.jmsr_28_17|s2cid=79825711 |doi-access= free}}</ref> The radiologic picture and the laboratory findings of serum calcium, phosphate and alkaline phosphatase are important differentiating factors. [[Blount's disease]] is an important differential diagnosis because it causes knee deformities in a similar fashion to rickets namely bow legs or [[genu varum]]. Infants with rickets can have bone fractures. This sometimes leads to child abuse allegations. This issue appears to be more common for solely nursing infants of black mothers, in winter in temperate climates, suffering poor nutrition and no vitamin D supplementation.<ref name="pmid18810424">{{cite journal | vauthors = Keller KA, Barnes PD | title = Rickets vs. abuse: a national and international epidemic | journal = Pediatric Radiology | volume = 38 | issue = 11 | pages = 1210–1216 | date = November 2008 | pmid = 18810424 | doi = 10.1007/s00247-008-1001-z | s2cid = 5848331 }}</ref> People with darker skin produce less vitamin D than those with lighter skin, for the same amount of sunlight.<ref>{{cite web | vauthors = Walker C | date = 8 July 2011 | work = Live Strong | title=CDark Skin Color & Vitamin D | url=http://www.livestrong.com/article/311881-dark-skin-color-vitamin-d/| access-date = 2 June 2012}}</ref>
