August 31, 2012This is a growing problem that affects the navicular bone of the foot in young children. Its not clear what, but something appears to disrupt some blood supply to the bone and a type of necrosis sets in. The navicular is at the high point of the arch, so it is subjected to a lot of pressure and this may account for the problem. The most common age of onset is around 5 years and it may cause limping. The pain can usually be located to the navicular bone. Often on x-ray, the bone appears much more narrower than the unaffected side. Usually this needs to be placed in a walking cast (more) to protect the foot and its growing bones. After the cast is removed foot orthotics are often used (link) to further protect the weightbearing on the navicular bone.
