The article discusses the effect of vitamin D on primary and secondary prevention of fractures and its effect on conditions after selected orthopaedic procedures. Fractures can be divided into traumatic, fatigue and pathological according to the cause. One of the complications of fracture is the formation of a nonunion. In addition to dealing with fractures, a total joint replacement is another common procedure in orthopaedic surgery. Because insufficient muscle strength can increase the risk of falls and thus result in a fracture, these topics are also mentioned in this article. Due to the impact of vitamin D deficiency on various musculoskeletal disorders, orthopaedic surgeons should pay more attention to the patients vitamin D status and be familiar with different strategies for preventing hypovitaminosis D, although clear evidence-based medical recommendations are still insufficient.
