Kohler Disease is a rare benign bone disorder, found in children between 4 and 9 years of age, which causes arch pain and discomfort.
This condition is caused from avascular necrosis (loss of blood supply) to the navicular bone, which is located in the midfoot and is usually self-limiting.
Due to the loss of blood supply, parts of the navicular bone can die, break or collapse, before healing and hardening. This condition is more prominent in boys but it can also affect girls.
Diagnosis of Kohler Disease (Arch Pain):
- X-ray, where the navicular bone will present with patchy sclerosis (thinned) and is often present with soft tissue swelling.
- CT and MRI, may be necessary if pain persists and the X-ray diagnosis is not clear.
- Physical examination.
