What is Kohler's disease?Kohler's disease is a rare condition that occurs in children aged between 3 and 7 that affects a bone in the foot called the navicular. The navicular is a small bone that is positioned midway up the foot on the inner side. Kohler's disease is caused by avascular necrosis, which results in death of bone tissue. Avascular necrosis occurs when the blood supply is cut off or reduced, in the case of Kohler's disease the blood supply to the navicular is inhibited and the bone flattens. A child that has Kohler's disease will present with a foot that is difficult to walk on and that is sore and swollen at the site of the navicular.
What causes Kohler's disease?The exact reason why Kohler's disease occurs is unknown, however, children between the ages of 3 and 7, particularly age 5 seem to be the most susceptible. Kohler's disease is a form of avascular necrosis that occurs at a bone in the foot called the navicular. Avascular necrosis occurs when a bone is starved of its blood supply, which causes the bone to die and change shape. In the case of Kohler's disease the navicular bone collapses and flattens.
What are the signs and symptoms of Kohler's disease?The signs and symptoms of Kohler's disease include the following:
- Walking on the outside of the affected foot
- Pain and soreness at the site of the navicular (middle inner side of the foot)
- Child between the age of 3 and 7 (more common in boys, but does affect girls)
How is Kohler's disease diagnosed?Kohler's disease is diagnosed based on the history, the signs and symptoms, and an examination of the foot. If Kohler's disease is suspected you may be referred for an X-ray to confirm the diagnosis.
