Avascular necrosis of the navicular in children is known as?

Avascular necrosis of the navicular in children is Kohler disease. It occurs when the navicular bone loses its blood supply, leading to bone death and pain in the midfoot. It most often affects young boys and presents with a limping child and midfoot pain. On imaging, early scans may be normal, but over time the navicular can become flattened, fragmented, or show changes like sclerosis and lucency as the bone heals or remodels. Other conditions involve different bones or ages. Sever’s disease is calcaneal apophysitis, so it causes heel pain but not navicular necrosis. Preiser’s disease is avascular necrosis of the scaphoid bone in the wrist. Mueller-Weiss syndrome is avascular necrosis of the navicular but occurs in adults, not children.
