The Pathobiology of Diabetes Mellitus in Bone Metabolism, Fracture Healing, and Complications.

Complications and inferior outcomes of fractures in the setting of diabetes mellitus (DM) are well documented. The incidence of DM is increasing rapidly, particularly in an aging and obese population. Thus, the combination of DM and fracture is becoming a serious health problem worldwide. As many fractures are relatively uncomplicated in the healthy patient population, a concerted effort to improve outcomes of fractures in patients with DM is warranted. In this article, we review relevant studies and examine the pathobiological mechanisms influencing fracture outcomes, including complications related to bone and soft-tissue healing, and infection.
