The aim of this research was to provide and document an accurate record of the noticeable occurrence of pes planus amongst adults in Bayelsa State (Nigeria). A random sample of 510 persons (235 males and 275 females; aged 33 ± 15 years and totally Bayelsa's natives) was analyzed. An ink imprint on white paper of their weight-bearing surface of the feet was carried out with diagnostic purposes. 48 males (20.4%) and 81 females (29.5%) revealed pes planus whereas the rest of the sample did not show it. The incidence of pes planus was 1:4. The well known frequent excess of bodyweight in these native groups may be responsible for this abnormality and obliges to pay due attention to the related habits. Furthermore, the obtained results could probably have anthropological and forensic medicine impact.
