Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Vitamin D is an essential hormone involved in bone metabolism, bone mineral density maintenance, and bone health. Vitamin D deficiency is putatively linked to poor pediatric orthopedic outcomes \[1\]. Further, the risk of low vitamin D associated fractures may be greater in minority pediatric populations \[2\]. In adults, utility of vitamin D alleles as a biomarker for bone density and fracture risk has been debated for over 10 years \[3-5\]. Peak bone density is achieved at 25 years old; however, most orthopedic trauma patients less than 25 years of age present with substantial vitamin D deficiencies.
