Q. Can flat feet be repaired by surgery? I have flat feet and I’m looking for all sorts of treatments for it- I heard there is a surgery for it- is it helpful?

A. As far as I know- they don’t treat flat feet that are asymptomatic. So first of all check if it bothers you. secondly there are 2 kinds of flat feet- rigid and flexible. There are different and treated differently. Not always a surgery (which is very painful and costly) is needed– I went to a Rolf method therapist by the advice of my orthopedic and it’s much better now. Ask an orthopedic.

Q. I think my son has flat foot, how to tell for sure? I didn't notice it before, he is 3 years old now and all shoes hurt him. Does it mean he has flat foot? what else can it be?

A. Pes planus (flat foot) is not a rare condition in toddlers, and may resolves spontaneously as the child grows. It is diagnosed clinically, i.e. by a doctor such as pediatrician or pediatric orthopedic surgeon, and radiographs are not universally indicated
