The number (n) and frequency (%) of upper and lower limb fracture types encountered in Edinburgh adults resulting from falls down stairs or falls from standing height are shown. The mean age of those affected is shown. Calculated odds ratios (with P values, chi-square tests) represent the likelihood of a given fracture type resulting from a fall down stairs, rather than a fall from standing. Odds ratios in bold type reflect those demonstrating either statistical significance or a trend towards significance.
