The fragility fracture is the widest spread of the bone diseases, in elderly. It particularly affects the vertebrae, the femur, the proximal humerus, the distal radius, the pelvis, thus preventing the patient�s free movement. The most debilitating of all these fractures is the fragility fracture of the pelvis. This type of fracture raises supplementary problems compared to the other fractures due to the difficulties of diagnosis, surgical approach and to the longer recovery period. Choosing the right treatment for FFP is difficult due to health and comorbidities in elderly patients. Both conservative and surgical therapy involve equally large risks: prolonged immobilization or surgical risks. Therefore, pharmacological therapy is an alternative to surgery. Bisphosphonates prove their utility in the fracture-healing outcome, but the influence of calcium and vitamin D were overlooked. The aim of our study was to evaluate the role of calcium and vitamin D in the healing process of patients with pelvic fragility fracture in osteoporotic patients with and without calcium and vitamin D supplementation. Our study shows that calcium and vitamin D exert a positive influence on the healing process of the fragility fractures and strongly emphasizes the need to educate patients to comply with the prescription to supplement calcium and vitamin D in order to improve fracture healing and prevent additional fractures.
