Evaluation of the Relation of Bone Densitometery with the Risk of Hip Fracture

Introduction & Because the numbers of hip fractures worldwide are projected to increase, osteoporosis will become an increasing burden on the health care system, in addition to causing pain, disability, and reducing quality of life. Mortality rate of hip fracture is 15-20% as compared to 0.9% of other orthopedic problems. The aim of this study is to determine the hip bone mineral density level that is predictive of fracture and whether osteoporosis is more prevalent in patients with hip fracture than in the age-and sex-matched group or not. In this prospective study the hip bone mineral density of 100 patients (50 men, 50 women) and 100 control individuals (50 men, 50 women) between 50-90 years old was measured by Dual-energy x-ray absorptiometry. The patients group had hip fracture after minor trauma. The statistical analysis of the two groups was done by t-test. This study showed that bone mineral density in the patients group was 0.6333 gr/cm2 versus 0.7589 gr/cm2 in the control group. The mean Z-score in the patients group was -1.218 versus -0.652 in the control group. The mean T-score in the patient group was -2.98 versus -1.98 in the control group. We recommend every person who has been screened by DXA and having bone density below 0.6333 gr/cm2 is prone to hip fracture. Moreover, hip fracture is associated with osteoprosis, which is more prevalent in the patients group than in the age-and sex-matched control group.
