- by eating certain types of food (including fish, dairy products, eggs and mushrooms);
- receiving sun exposure; and
- taking supplements
- 411 (57 percent) had normal Vitamin D levels,
- 202 (28 percent) had insufficient levels; and
- 110 (15 percent) were vitamin D deficient.
In a retrospective chart review, Dr. Lane and his colleagues measured Vitamin D levels of 723 patients who were scheduled for orthopaedic surgery between January 2007 and March 2008 and determined the prevalence of normal, insufficient and deficient levels according to the following parameters:
- Normal: equal to or greater than 32 nanograms per milliliter (ng/mL)
- Insufficient: less than 32 ng/mL
- Deficient: less than 20 ng/mL
Calcium and Vitamin-D Supplementation for Patients with a Fracture
Calcium and vitamin-D supplementation is a baseline critical component of any fracture treatment therapy. The increased bone turnover stimulated by fracture repair and remodeling leads to an increased metabolism and demand for calcium and vitamin D. The estimated daily intake required for fracture-healing is 1500 to 2500 mg of calcium and 1000 to 2000 IU of vitamin D.
