Purpose of review
Evidence has accumulated to show the prevalence of vitamin D
insufficiency and deficiency in all age groups. Inadequate exposure to sunlight and to dietary sources contribute to the reemergence of musculoskeletal problems attributable to hypovitaminosis D.
There is a growing body of evidence for the alarming prevalence of vitamin D
insufficiency and deficiency among healthy adolescents, adults, and elders. Several studies show increased prevalence of vitamin D
deficiency among patients with fractures and patients with persistent musculoskeletal pain
. Evidence suggests that genetic variations in the vitamin D
receptor are associated with fracture
risk. There has been a reconsideration of the range of normal laboratory values and recommended daily intake of vitamin D
for different groups of individuals. New strategies are needed to identify individuals who would benefit from vitamin D
treatments. Identification of vitamin D
deficiency in patients with fractures and its correction require the education and cooperation of multiple specialists.
Physicians and orthopedic surgeons need to be alert to populations at risk of hypovitaminosis D. Immediate correction and maintenance of vitamin D
adequacy require interactions of medical specialists.
