Vitamin D deficiency is apt to cause stress fractures

"Vitamin D levels can influence the body's calcium and phosphorus in food intake element", the first author of the article, the University of Pennsylvania School of Medicine, Jason R Miller said.

They found that the amount of calcium in patients with insufficient levels of vitamin D intake of only 10% to 15% of the ordinary people, phosphoric acid and intake of 50% -60%. "As a result, inadequate intake of these elements results in a lower degree of mineralization of bone tissue."

However, the authors also pointed out that the degree of vitamin D deficiency in these patients can be predicted to get. "To ensure that fully functional bone health was the lowest 25-hydration serum vitamin D levels still inconclusive." However, "we hope to establish a standard vitamin D content by way of discussion, suggesting that patients risk for stress fractures."

Stress fractures are usually sports injury, when the bone pressure greater than its maximum pressure to withstand stress fracture will occur events. The researchers analyzed data from the period 2011 to 2014, Miller's 124 doctors diagnosed a stress fracture of patients' records, the results showed: serum 53 patients during the 25-month average concentration of vitamin D was 31.1 hydration ng / ml. Where the content is less than 44 patients 40ng / ml, according to the standard vitamin D committee, this value indicates vitamin D deficiency; in addition, there are 28 patients with vitamin D levels less than 30ng / ml.

One-third of patients with second metatarsal stress fracture occurred, 17.6% in the third metatarsal stress fractures occurred.

"Studies have reported the content of 25- hydrated before contacting vitamin D and stress fractures among the lowest they recommended serum levels of vitamin D can not be less than 40ng / mg, especially for the physical activity needs of the larger population." .
