Kohler Disease is a rare bone disorder that affects the feet of young children, typically between the ages of 3 and 7. It is characterized by pain, swelling, and tenderness in the middle of the foot due to temporary damage to a small bone.

The small navicular bone in the arch of the foot temporarily loses its blood flow, causing the bone tissue to become damaged and collapse. This interruption in blood supply is usually caused by excessive pressure during walking or running before the bone has fully hardened. The condition typically affects only one foot.
Symptoms define localized foot pain. These include pain, tenderness, and swelling over the arch of the foot. The pain often causes the child to limp and avoid bearing weight on the affected side. The pain usually worsens with activity and improves with rest.
The condition affects foot development temporarily. While the navicular bone is damaged, the condition is usually self-limiting. The blood supply typically returns, and the bone slowly regains its normal density and shape, causing the symptoms to resolve spontaneously.
Diagnosis relies on imaging tests. X-rays of the foot are needed to confirm the diagnosis, showing a characteristic flattened and dense appearance of the navicular bone. The X-ray is often the definitive diagnostic tool.
Necessary treatments focus on pain relief and immobilization. The foot is typically immobilized in a cast or walking boot for several weeks to relieve pressure on the damaged bone. Non-steroidal anti-inflammatory drugs are used to manage pain. No long-term damage usually occurs.
Yes, Kohler Disease is self-limiting and resolves on its own without long-term damage.
No, it is caused by a loss of blood supply to the bone (osteochondrosis), not a break from physical stress.
Yes, Kohler Disease typically affects only one foot.
Consult a pediatric orthopedist if a young child (age 3-5) begins limping and has swelling over the "navicular bone" of the foot. While the bone's blood supply eventually restores itself, the child may require a cast or arch supports to manage pain and ensure proper foot alignment during recovery.
