Increasing Incidence of Osteomyelitis Save

A Mayo Clinic analysis of trends in osteomyelitis disclosed 760 new cases between 1969 and 2009 in Olmstead county. Rates increased from 11.4 cases per 100,000 person-years for the period from 1969 to 1979 to 24.4 per 100,000 person-years in the period from 2000 to 2009. Rates were stable in children but tripled in those over age 60 years, especially amongst diabetics. Forty percent were due to Staphylococcal infection. The reasons for the increase in osteomyelitis between 1969 and 2009 are unclear but could comprise a variety of factors, including changes in diagnosing patterns or increases in the prevalence of risk factors (e.g., diabetes) in this population.
