| Stage | X-ray Finding | Clinical Presentation | Treatment | Prognosis |
|---|---|---|---|---|
| Early (Precondensation) | Normal or mild irregularity; navicular may appear smaller | Midfoot pain with activity; limping; antalgic gait | Activity modification; supportive footwear; observation | Excellent — often resolves spontaneously |
| Active (Condensation / Fragmentation) | Dense, flattened, fragmented navicular — “coin on edge” or “wafer” appearance | Medial midfoot tenderness; swelling; pain with walking | Short-leg walking cast 4–8 weeks; significantly shortens symptomatic period | Excellent — navicular reconstitutes fully in 1–4 years |
| Healing (Reconstitution) | Navicular gradually regains normal density and shape | Decreasing pain; improving function | Supportive footwear; custom orthotics to protect during remodeling | Excellent — normal adult navicular morphology in 94–96% of cases |
| Pediatric Osteochondrosis | Bone Affected | Age / Sex | Mechanism | Outcome |
|---|---|---|---|---|
| Köhler Disease | Navicular | 3–7 years; boys 4:1 | Compressive stress on immature navicular during vulnerable ossification window | Excellent — full remodeling; no long-term sequelae |
| Freiberg Infraction | 2nd (or 3rd) metatarsal head | 13–18 years; female predominance | AVN of metatarsal head; high heels, repetitive stress | Variable — metatarsal head collapse may cause permanent deformity; surgery in advanced cases |
| Sever Disease | Calcaneal apophysis | 9–14 years; boys more common | Achilles traction on growth plate; most common pediatric heel pain | Excellent — resolves at physeal closure; no deformity |
| Iselin Disease | 5th metatarsal apophysis | 10–14 years | Peroneus brevis traction on apophysis | Excellent — self-limiting at skeletal maturity |
| Osgood-Schlatter (reference) | Tibial tubercle (knee) | 10–15 years; boys | Patellar tendon traction apophysitis | Excellent — self-limiting; bony prominence may persist |
Kohler disease in children — a temporary loss of blood flow to the navicular bone — usually resolves on its own within 6-24 months with the right activity modification and shoe support.

Kohler disease is a self-limiting condition affecting the navicular bone in children, typically between ages 4 and 8. The condition causes foot pain, limping, and swelling but is almost always benign and resolves without surgical intervention. At Balance Foot & Ankle, Dr. Tom Biernacki specializes in diagnosing and managing Kohler disease to minimize pain and allow normal healing.
Understanding Kohler Disease
In Kohler disease, the navicular bone undergoes a period of disrupted blood supply and aseptic necrosis, causing inflammation and pain. The condition typically presents with foot pain over the inner arch, limping, and reluctance to walk or play. X-rays show characteristic changes in the navicular bone. The good news is that the condition almost always resolves completely as the bone heals.
Treatment Approach
Treatment focuses on reducing pain and protecting the navicular bone during healing. Dr. Biernacki recommends activity modification, supportive footwear, and custom orthotics or a protective foot brace to offload the navicular bone. Pain typically resolves within 2-3 months, and the bone completely heals by age 10-12.
Activity and Return to Sports
During the acute phase, activities should be limited to pain-free movements. As pain improves, children gradually return to normal activities. Complete return to sports is allowed once pain resolves and the child feels confident. Dr. Biernacki monitors healing with periodic X-rays to ensure the bone is remodeling normally.
Long-Term Outcomes
Kohler disease has an excellent long-term prognosis. The bone completely remodels by age 10-12 without any permanent changes or functional limitations. Children treated appropriately experience pain relief and return to normal activities without restrictions.

Frequently Asked Questions
Is Kohler disease serious?
No, Kohler disease is not serious. It’s a self-limiting condition where the navicular bone heals completely without surgery. With proper management, pain resolves and children return to normal activities.
How long does Kohler disease last?
Acute pain typically lasts 2-3 months. Complete bone healing takes 6-24 months. Most children are pain-free and back to normal activities within 3-4 months of diagnosis.
Can my child play sports with Kohler disease?
During the acute phase, sports that cause pain should be avoided. As pain improves, gradual return to activities is appropriate. Once pain-free and the child feels confident, normal sports participation is allowed.
Will Kohler disease cause permanent problems?
No, Kohler disease causes no permanent problems. The bone completely remodels, and children develop completely normal feet with no long-term functional limitations or restrictions.
