Kohlers - Avascular Necrosis of the Navicular

Kohler’s disease is a condition that affects the lower inside part of your child’s foot and can affect either one or both feet. The bone affected is the last in a child’s foot to calcify. It usually takes longer for boys’ bones on this part of the foot to calcify and as such, Kohler’s disease is more likely to be experienced by boys aged between 6-8 years old.

In the instance of Kohler’s disease, the calcifying process puts vast pressure on the flow of blood, which results in pain.

Your child may have Kohler’s disease if:

  • They experience pain in the middle part of their foot
  • They experience warm, red and swollen feet
  • They have a tender point right near their navicular (inside of the arch)
