  1. Every bone represented in the database by more than 50 fractures is tabulated. Column totals do not always add up because some information is missing; for example, some fractures were not defined as either open or closed. The total of all bones is larger than the total count of patients because some patients broke multiple bones. The heal rate (HR) in humerus is significantly lower than the overall HR because the confidence interval (CI) for humerus does not overlap the CI for “All fractures.” Bolded HR numbers are above the CI associated with “All fractures.” Italic HR numbers are below the CI associated with “All fractures.” In the “Elderly” group, bolded HR numbers are above the CI for the corresponding fracture in the whole cohort, while italic HR numbers are below the CI for the corresponding fracture in the whole cohort. Elderly HR is comparable to the HR of the overall sample.
