Estimation of sex on the basis of radiographs of the calcaneus.
Lateral and anteroposterior radiographs of the ankles of 800 Central Europeans aged 20 to 79 were analyzed with regard to sexual dimorphism. All the distances, but not the angles, of the calcaneus were much larger in males than in females. Approximately 80% of the study sample could be sexed correctly by classifying all specimens greater than 86.0 mm in length as male and those less than 86.0 mm as female. The prevalence of os tibiale externum was 8.0 and 2.6% and the prevalence of plantar heel spur was 16.3 and 6.5% (increasing with age) for males and females, respectively, being significantly more frequent in females. On the other hand, the bone island frequencies were 9.1% in males and 4.8% in females. Our study suggests that radiographs of the ankle are a convenient, rapid, cheap and non-invasive means for estimating sex.
