Background The hip fracture is the most serious complication of osteoporosis. It is a public health issue in elderly because of its frequency, severity and economic impact. We report the result of an 18 months investigation. Objectives The aim of this study was to determine the frequency of osteoporotic hip fractures and identify the risk factors of osteoporosis and falls leading to these fractures. Methods Cross-sectional, prospective, descriptive study. Were included patients with spontaneous or secondary low trauma hip fractures during 18 months, who consulted at trauma unit, Mohamed Lamine Debaghine hospital. Have been collected: patient characteristics, risk factors for osteoporosis and falls, type of treatment and length of hospital stay. Results 115 cases of hip fractures were recorded out of a total of 486 fractures, with a frequency of 16.8%, from all the fractures operated, it represents 22.7%. We noted a female predominance (62.6%) with a sex ratio of 0.60, the average age is 76.44 +/- 11.71 years. The associated comorbidities are: cardiovascular (55.7%), diabetes (33%), dysthyroidism (11.4%), asthma (10.4%), chronic renal failure (5.2%) prostate adenoma (4.5%). The fracture mechanism is dominated by the fall (92%), it is most often a domestic accident: slipping (30%), stumbling (26%), ablution (11%), falling on the stairs (7%).%). The risk factors for osteoporosis identified are: age more than 70 years (72.8%), female sex (62.6%), low BMI (18%), sedentary lifestyle (15.3%), corticosteroid therapy 7.2%, smoking (6.3%), history of rheumatoid arthritis in 3.4% and early menopause in 2.1% of patients. The risk factors of fracture: visual disturbances (40%) neuromuscular disorders in 11, 9%, poor health (more than 3 chronic diseases) in 9% of patients, mother’s history of hip fracture (1.7%). A personal history of osteoporotic fracture was noted in 17.4%, 7 patients presented a contralateral hip fracture. The average duration of hospitalization is 5.2 +/- 2.5 days. The treatment is surgical in 81.6% (40.8% prostheses). Conclusion Through this study, we found that osteoporotic hip fracture is frequent. The osteoporosis risk factors identified were female sex, advanced age, corticosteroid therapy and sedentary lifestyle. Fall risk factors were dominated by visual disturbances and neuromuscular disorders. References [1] Charles M. Court-Brown, Ben Caesar. Epidemiology of adult fractures: A review. Injury 2006.
