Further larger patient cohort studies are needed to support our results. Our results strongly showed a high correlation between pes planus and hallux valgus. There are few reports in the literature about the relationship between pes planus and hallux valgus. Terminology Pes planus is also known as flatfoot, planovalgus foot or fallen arches 7. Calcaneal pitch angle and lateral talocalcaneal angle showed significant negative correlation with HVA and IMA. Pes planus is a deformity of the foot where the longitudinal arch of the foot is abnormally flattened and can be congenital or acquired.
Calcaneal pitch angle was significantly lower in the case group, whereas talonavicular angle was higher in the control group. There was no significant difference in talonavicular and Meary's angles between the groups. As opposed to pes planus (flat feet), which is often a flexible disorder of the foot that we try to correct with orthotics (i.e., push back into the correct position), pes cavus is usually a rigid deformity,meaning that the shape of the foot cannot be changed. All patients’ HVA, IMA, and talonavicular coverage angle on anteroposterior (AP) foot radiographs and talar-first metatarsal angle (Meary's angle), calcaneal pitch angle, and lateral talocalcaneal angle on lateral foot radiographs were measured. Often times if the feet have become painful, orthotic inserts are prescribed. 54 patients with hallux valgus angle (HVA) >20° and intermetatarsal angle (IMA) >9° were evaluated in the case group and 159 patients randomly selected from those admitted for a recent foot ankle trauma with the HVA <15° and IMA <9° were the control group. A total of 213 patients were included in this study between May 2013 and May 2014. Hypermobile flexible pes planus is usually due to ligamentous laxity. In this study, we aimed to show the relationship between hallux valgus and pes planus in adult males. Most flexible flatfoot deformities are asymptomatic. Many structural foot disorders have been suggested as the cause of hallux valgus deformity. And the entire sole of the feet touches the ground during standing.
Hallux valgus is one of the most common and painful deformities, occurring due to adductor/abductor imbalance of the big toe. What is Pes planus Pes planus is also known as Flat foot is a postural deformity in which your medial longitudinal arch gets collapsed or lowered towards the ground.
