57% inadequate (< 30 ng)
27% deficient (20 ng)
4% severe deficient (< 10 ng)
The paper, presented Thursday at the North American Spine Society annual meeting,
Buchowski said the idea of checking vitamin D levels of patients first occurred to him in 2008.
A woman in her 40s who had undergone cervical fusion surgery and did not get an adequate fusion told him that she had been treated for a vitamin D deficiency.
"It was like a light bulb went off," he said.
For the last year and a half, all patients undergoing fusion surgery at Washington University have their vitamin D levels checked.
If they are deficient, they will be supplemented with a 50,000 IU prescription dose once a week for eight weeks before their surgery, he said.
