Abstract
This study examines differences in sex-based criteria for axial loading of the ankle. Seventeen (17) right legs were excised from cadavers representing midsized males (6), large females (6), and small females (5). Each specimen was exposed once to high-rate axial loading (average 4.7m/s within 10ms) at the calcaneus. Axial load was measured at the proximal aspect. High-speed x-ray was used to determine time of fracture, and therefore uncensored fracture load. A strong trend in fracture force reduction from males to females is seen. Statistical significance across groups was observed using ANOVA. Unpaired Student’s t-tests disclosed significant differences between midsized males and both large females and small females. Differences between midsized males and large females suggest fracture load is related to sex, not just size. Additional biomechanical data for females are needed.
