INTRODUCTION Children present with flatfoot from birth and it resolves along infancy. There have been several risk factors identified for the development of flatfoot: male sex, young age, overweight and obesity. The prevalence of flatfoot decreases with age. The aim of this study was to determine the prevalence of flatfoot in two different populations with different social, cultural and geograp...

This study quantified and compared the efficacy of in-shoe orthoses and ankle braces in stabilizing the hindfoot and medial longitudinal arch in a cadaveric model of acquired flexible flatfoot deformity. This was addressed by combining measurement of hindfoot and arch kinematics with plantar pressure distribution, produced in response to axial loads simulating quiet standing. Experiments were c...

Foot and ankle specialists acknowledge that flatfoot deformity is a frequently encountered pathology in the pediatric population. Flattening of the medial arch is a universal finding in flatfoot and it is common in both pediatric and adult populations. Pediatric flatfoot comprises a group of conditions occurring in infants, children, and adolescents (1) that are distinguished by anatomy and eti...

Background: The change in foot posture can possibly generate changes in the pelvic alignment. There is still a lack of evidence about the effects of bilateral and unilateral flatfoot on possible changes in pelvic alignment. The purpose of this study was to investigate the effect of flatfoot on the sagittal and frontal planes of pelvic postures. Materials and Methods: 56 subjects, aged 18–40 yea...

BACKGROUND The purpose of this study was to investigate the relationship between flexible flatfoot and plantar fasciitis. METHODS Twenty-three subjects with flexible flatfoot and 23 subjects with normal arched feet were enrolled. Footprint analysis was used to evaluate the foot conditions in both groups to calculate the individual arch index. We compared the sonographic images of plantar fasc...

Introduction The objective of this presentation is to highlight the clinical and laboratory-based research related to posterior tibial tendon dysfunction (PTTD). Methods and results • Defining the flatfoot: clinical, foot pressure, radiologic • Critical evaluation of flatfoot deformity: in vitro • How often does the flatfoot occur? • Normal arch development • Why is the flatfoot a problem? • Wh...

PURPOSE Medial longitudinal arch (MLA) strengthening has been considered an important part of successful flatfoot treatment. But, to date, the biomechanical loading behavior of the medial arch in flatfoot has not been evaluated. This study aimed to evaluate the MLA moment, MLA deformation angle, foot kinematics and ground reaction forces (GRF) in both normal foot and flatfoot groups. METHODS ...

While being one of the most frequent parental complained deformities, flatfoot does not have a universally accepted description. The reasons of flexible flatfoot are still on debate, but they must be differentiated from rigid flatfoot which occurs secondary to other pathologies. These children are commonly brought up to a physician without any complaint. It should be kept in mind that the etiol...

In 1 of our previous studies, the occurrence of self-reported flatfoot was associated with self-reported increased age, male gender, Asian and African American races, veteran status, poor health, increased body mass index, callus, bunion, hammertoe, and arthritis. However, we had to rely on survey data to identify these risk factors, and the accuracy of the survey results was unknown. Therefore...

Foot and ankle specialists agree that flatfoot is a frequently encountered pathology in the adult population. For the purpose of this document, adult flatfoot is defined as a foot condition that persists or develops after skeletal maturity and is characterized by partial or complete loss (collapse) of the medial longitudinal arch. Adult flatfoot may present as an incidental finding or as a symp...
