The annual incidence of peripheral bone infection in developed countries is below 2%, but incidence increases after surgical care of open or closed fractures, and in immunocompromised patients.[1]Glaudemans AWJM, Jutte PC, Cataldo MA, et al. Consensus document for the diagnosis of peripheral bone infection in adults: a joint paper by the EANM, EBJIS, and ESR (with ESCMID endorsement). Eur J Nucl Med Mol Imaging. 2019 Apr;46(4):957-70.

One study in the US showed that the overall age- and sex-adjusted annual incidence of osteomyelitis was 21.8 cases per 100,000 person-years between 1969 and 2009. The annual incidence was higher for men than for women and increased with age.[7]Kremers HM, Nwojo ME, Ransom JE, et al.

During the study period, incidence rates remained stable among children and adults ages <50 years but almost tripled among older adults, mostly driven by a secular increase in diabetes-related cases. The incidence of diabetes-related osteomyelitis quadrupled over the three decades of investigations.[7]Kremers HM, Nwojo ME, Ransom JE, et al.

The annual incidence of hospitalization for vertebral osteomyelitis in the United States rose from 2.9 per 100,000 in 1998 to 5.4 per 100,000 in 2013.[8]Issa K, Diebo BG, Faloon M, et al.

The incidence of acute hematogenous osteomyelitis in children ranges from 1.2 to 13 cases per 100,000 children per year.[4]Woods CR, Bradley JS, Chatterjee A, et al.

This varies geographically with increased incidence in resource-limited countries and over time with the emergence of virulent pathogen strains, particularly community-acquired methicillin-resistant Staphylococcus aureus in the United States.[4]Woods CR, Bradley JS, Chatterjee A, et al.
