ABSTRACT
ABSTRACT There is no specific age when the vault of the feet is completely formed. The objective of this study was to analyze the footprint morphology and obtain the Chippaux-Smirak Index in a Mexican population to identify the type of feet and its prevalence. A database of images of the soles of both feet was analyzed. The database contained images of 1,014 persons between 2 and 73 years old from Guanajuato state, Mexico. Moreover, a literature review was performed to identify the type of feet in the Mexican population. It was observed that less than 17 % of the population have cavus foot (p= 0.018). Furthermore, less than 25 % of the population between 17 and 73 years have flatfoot 3 (p= 0.0079) in the left foot. Also, only nine articles related to the type of foot in the Mexican population were found, but most of them were performed on young population. The formation of the medial arc could be beyond the first decade of life and the relatively high prevalence of flatfoot in adult life should be studied. Finally, the results found can be useful for orthopedists, physiotherapists, clinicians, and parents who are concerned about the foot health of their children.
RESUMEN No hay una edad específica en la que la bóveda de los pies esté completamente formada. El objetivo de este estudio fue analizar la morfología de la huella de los pies y obtener el Índice de Chippaux-Smirak en una población mexicana para identificar el tipo de pie y su prevalencia. Se analizó una base de datos de imágenes de las plantas de ambos pies. La base de datos contenía imágenes de 1,014 personas de entre 2 y 73 años del estado de Guanajuato, México. Además, se realizó una revisión bibliográfica para identificar el tipo de pie en la población mexicana. Se observó que menos del 17 % de la población tiene pie cavo (p= 0,018). Además, menos del 25 % de la población entre 17 y 73 años tiene pie plano 3 (p= 0,0079) en el pie izquierdo. Además, se encontraron 9 artículos relacionados con el tipo de pie en población mexicana, pero la mayoría de ellos fueron desarrollados en población joven. La formación del arco medial podría estar más allá de la primera década de vida. Se encontró una prevalencia relativamente alta de pie plano en la vida adulta que debe ser estudiada. Finalmente, los resultados encontrados pueden ser útiles para ortopedistas, fisioterapeutas, médicos y padres preocupados por la salud de los pies de sus hijos.
ABSTRACT
Background: A flexible flatfoot is considered to be a variation of a normal foot. Any deviation from the anatomical plantigrade foot is a deformed foot. Some of the deformities of the foot are: Flat Foot. The normal concavity due to the medial longitudinal arch is absent. High Arch Foot - A normal foot has a medial longitudinal arch which is higher. Materials and Methods: A total population of 625, in age ranging from 5 year to 9 years in Kanchipuram district was chosen. Each individual was made to sit and the foot was brought in contact with the Foot Impression gaining Kit on white sheets in standing posture. Results: The flat feet and high arch feet evaluation was obtained by means of foot prints and the plantar arch index was established. The mean values of plantar arch index within the age group were stable and ranges from 0.72 to 0.73. With plantar arch indices greater than 1.15 was regarded as flatfeet and less than 0.10 was regarded as High arch feet. Discussion: In normal feet with presence of an arch, the stress will be distributed in an even manner so that the person will not experience any kind of pain. Under an abnormal condition that occurs due to lack of stretching of muscles, bones and tendons, there will be absence of arch among these people. In this condition, all the weight will be concentrated in smaller area on the feet and generates a lot more pain than normal. This condition might occur in both children and adults. In some people both feet will be flat and in some only one foot will be flat. Conclusion: Flat foot is highly prevalent in the ages between 5-9. The average values for plantar arch indices are stable and ranges from 0.72 to 0.73 in our sample regarded as Normal foot. Plantar arch index > 1.15 is regarded as Flat foot. Plantar arch index < 0.10 is regarded as High arch foot.
