[25-OH-vitamin D in the serum of patients with femoral-neck fractures].

In 10 women with femoral neck fracture, 10 with fracture(s) evolved from accidents (mainly traffic accidents) and 10 without disease (controls) in January and July, the 25-OH-vitamin D levels in serum were measured by a competitive protein binding assay. Patients with femoral neck fractures exhibited significantly (p less than 0.05) lower 25-OH-vitamin D levels than the other groups. Additionally, in patients with femoral neck fractures calcium x phosphate product in serum was subnormal (below 25). In Germany, prophylactic dietary supplementation of vitamin D seems feasible.
