Global Overview of Acquired Upper Limb Amputation Epidemiology: A Systematic Review of Prevalence, Incidence, Level, and Etiology

Upper limb amputation leads to significant physical and psychosocial burden; however, it remains underrepresented in global epidemiological and rehabilitation studies. This study aimed to systematically review the global epidemiological data on upper limb amputation, focusing on its prevalence, incidence, anatomical levels, and etiology. According to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, a comprehensive literature search was conducted using PubMed, Embase, Cochrane Library, and Regional Information Sharing Systems (up to May 2023). Two authors independently selected the studies, assessed their methodological quality, and summarized the evidence. Nineteen studies were finally included in this study. The prevalence of major upper limb amputation was higher in individuals with disabilities than in the general population. The prevalence in general population was 11.6 per 100,000 adults between 2006 and 2008 in Norway, whereas the prevalence in individuals with disabilities was 6.9 per 1,000 individuals in 2011 and increased to 11.3 per 1,000 individuals in 2020 in South Korea. The incidence rates were generally higher in the occupational population than in the general population. Below-elbow amputation was consistently the most common major amputation level reported. Although traumatic causes were predominant, medical conditions substantially contributed to upper limb impairment among individuals with disabilities. Upper limb amputation presents significant global variations in prevalence, incidence, anatomical level, and cause. The scarcity of standardized, disaggregated data limits effective planning for prosthetic services and rehabilitation. Future studies should prioritize comprehensive data collection to support equitable healthcare delivery and inform prosthetic innovation.
