Comparison of 25-OH vitamin D levels between children with upper and those with lower extremity fractures: A prospective case-control study

Abstract

Objective: The aims of this study were (1) to compare 25-OH vitamin D levels between children with upper and those with lower extrem- ity fractures and (2) to determine whether 25-OH D insufficiency prevalence is increased compared to healthy controls. Methods: This is a prospective case–control study for 12 months. The study was conducted with children aged 5-18 years, including 60 children with non-displaced, impaction type upper extremity and lower extremity fractures resulted from low-energy trauma. In addi- tion, 60 healthy children were included as controls. In all participants, risk factors for low bone mineral density were assessed and serum 25(OH)D levels were measured. Vitamin D levels were compared among groups. Results: Vitamin D deficiency (25-OH D
