Epidemiology of long bone non-unions in Spain

Epidemiological and ecological studies on long bone non-unions (NU) are scarce, based different populations methodologies. The aim of this study was to produce a descriptive analysis the femur, tibia, humerus non-union epidemiology in Spain.Methods Data were obtained from Minimum Basic (Conjunto Mínimo Básico de Datos, CMBD) Hospital Discharge Database Spanish Ministry Health, according ICD9-CM coding for diagnoses procedures, National Institute Statistics population, generating secondary databases with reported cases that included code 733.82 disaggregated manner, by age (categorized 5 intervals), gender, region, calendar year (1997-2015). Percentage related fractures previous year, annual prevalence (expressed per 100,000 person-years) period person-period) calculated age, regions. Odds ratio (OR) estimated confidence 95% using logistic regression model anatomical site.Results A mean 235,446 all locations annually Spain 1997 2015. Regarding bones (femur, tibia humerus), total 37,053 found, representing yearly 1,950 cases. proportion evolved into 4% (1.4% 1.5% 1% humerus). rate NU 4.5 (3.7-4.9) persons-year. overall 86 persons. By type bone, (per persons-period) femur 31, 33, 22.Conclusions This description confirms has been stable 2000 2015, higher compared humerus. occurred more frequently aged females than males humerus, while frequent younger age.
