Background: Lower extremity and pelvic fractures (LEPFs) are common and debilitating injuries with substantial global health and economic burden, yet comprehensive epidemiological data remain limited.Based on Global Burden of Disease 2021, we analyzed incidence, years lived with disability (YLDs), and causes of LEPFs across 204 countries from 1990 to 2021， along with their temporal trends. The impact of age, sex and Socio-Demographic Index (SDI) was considered.In 2021, 78.05 million new LEPF cases were reported globally, a 32% increase since 1990. Despite this, the age-standardized incidence rate (ASIR) declined annually by 0.68%, reaching 974.98 per 100,000 population in 2021. For anatomic subtypes, fractures of the patella, tibia or fibula, or ankle were most common (34.96 million), while hip fractures showed the largest increase for incident cases (126%) and a significant rising ASIR among males (0.21% annually). Conflict-affected countries in the Middle East and Africa saw the sharpest rises in LEPF burden. SDI correlated with elevated ASIR and age-standardized YLD rates (ASYR), particularly at SDI >0.7. Falls were the leading cause, followed by road injuries. YLDs peaked among adults aged 45-60, with ASYR rising sharply in older populations. The disability burden increased during COVID-19 pandemic, exposing vulnerabilities in global fracture care systems.Conclusions: LEPFs remain a significant public health challenge, driven by population aging, regional instability and osteoporosis. Hip fractures in males and LEPFs in conflict zones demand urgent attention. Strengthening fall prevention, implementing comprehensive osteoporosis management including sex-inclusive approaches, and targeted prevention strategies is essential to mitigating the global burden of LEPFs.
