Vitamin D is necessary for the regulation of calcium and phosphate in the human body and decreased levels can alter the bone mineralization process. There is a high prevalence of vitamin D deficiency in the general population and low vitamin D is associated many disorders such as rickets and osteoporosis.1
Unfortunately, universal guidelines for optimizing vitamin D levels have not been adopted by orthopaedists and despite significant effort, this topic is not an integral part of the majority of residency training programs. Although this can be partially blamed on attitudes among orthopaedists, the multitude of recommendations given in the literature by endocrinologists can be confusing and require significant effort to synthesize into a viable approach to a given patient.
