Hip fractures in a developing country: osteoporosis frequency, predisposing factors and treatment costs.

Hip fractures are a burden to both society and the individual. The aim of this study was to describe the frequency of osteoporosis and the in-hospital treatment costs of patients with hip fractures admitted to Hacettepe University Faculty of Medicine Hospital. Patients with a hip fracture who were admitted to the Orthopedics and Traumatology wards between April 2003 and December 2006 were interviewed and 50 of them were enrolled prospectively in the study protocol. Patient characteristics, predisposing factors for fractures and hospital costs were recorded as well as laboratory test results and bone mineral density measurements. The mean age was 74.2 years and 72% of the patients were women. Sixty-four percent of them presented with an intertrochanteric fracture. The patient population was significantly debilitated with a high prevalence of vitamin D insufficiency and secondary hyperparathyroidism. No association was shown with T scores and dietary habits and lifestyle characteristics of patients. In 34% of patients in whom measurements were available, no osteoporosis could be documented. The mean hospital expenditure was $5983. Factors affecting the total cost were age and functional status of the patient and the duration of hospital stay, independent of the type of fracture and surgical procedure used.
