ADULT ACQUIRED FLATFOOT
POSTERIOR TIBIAL TENDON DYSFUNCTION
When children are born their feet always have a flat appearance. This is normal. When children start to walk their bodies undergo changes, one of those changes is the formation of an arch in the foot that is designed to soften the pressure on the legs when walking. there are many occasions when arches do not form properly. We call this a flatfoot ( Pes Planus is the medical terminology ). So there is flatfoot from childhood and there is one other type- the flatfoot that appears later in life. We commonly call this adult acquired flatfoot. This can be caused by a few different situations- one of those is an injury to a structure called the posterior tibial tendon. This tendon and muscles job is to help hold up the arch against the force of the body weight, injuries to this tendon can be chronic (meaning happen over time) or acute (like a tear).
