Association of Vitamin D With Stress Fractures: A Retrospective Cohort Study
J Foot Ankle Surg. 2016;55:117-120.
Why You Should Care:
Nothing can ruin a race season quicker than a stress fracture. Every athlete has either had one or knows someone who has. They start as a nagging pain that won’t go away and wind up as six weeks of interrupted training and your planned PR down the drain.
- The researchers reviewed the records of 53 patients who had been diagnosed with a stress fracture in the last 3 months. 44 of the patients had a serum 25-hydroxyvitamin D level <40mg/ml
- The researchers concluded “an association was seen in patients with stress fractures and a serum 25 (OH) D levels <40mg/ml
- The researchers proposed that “greater that previously understood serum concentrations of Vitamin D might be necessary to prevent stress fractures in active individuals.
What It Means For You:
- Stress fractures are a common injury that occurs when stress on a bone exceeds its capacity to withstand those forces.
- Evidence links insufficient levels of Vitamin D to stress fractures
- Researchers recommend a minimum serum Vitamin D level to prevent stress fractures
- The only way to determine your level is adequate is to see your Health Care Provider and confirm it with a blood test.
