RESUMO
This work studies the epidemiology of hip fracture in Egypt. While the incidence of hip fracture in Egypt matches that of the Mediterranean region, there was geographic variation in osteoporotic hip fracture incidence between the north and south of Egypt. PURPOSE: To assess the incidence of hip fracture in Egypt, with special emphasis on the geographic and demographic variation among the Egyptian population. METHODS: The incidence of hip fractures treated in two Egyptian FLS centers was calculated for the period of February 2022-February 2023. Demographic information was recorded for every patient on the national register. All patients completed a baseline questionnaire, had clinical evaluation, fracture risk, falls, and sarcopenia risk assessment. A DXA scan was carried out for every patient. RESULTS: The annual incidence of low-energy hip fracture in individuals aged 40 years or more in Egypt in 2022-2023 was 123.34 per 100,000 in women and 55.19 per 100,000 in men. The incidence of hip fractures was higher in south Egypt (113.62) versus north Egypt (64.8). This was consistent for both genders. Bone mineral density was significantly (p < 0.01) lower in south Egypt at both the spine, distal forearm, as well as hip trochanters, whereas there was no significant difference between both locations in terms of the total hip and neck of the femur. Yet, falls risk, sarcopenia, as well as functional disability rates were significantly (p < 0.001) higher in the north. CONCLUSION: In Egypt, the hip fracture incidence was higher in the south compared to the north. Several modifiable factors contribute to fragility fracture risk independent of BMD, creating complex interrelationships between BMD, risk factors, and fracture risk.
