| Feature | Kohler Disease | Freiberg Disease | Sever’s Disease |
|---|---|---|---|
| Affected bone | Navicular (midfoot arch bone) | Metatarsal head (usually 2nd) | Calcaneal apophysis (heel growth plate) |
| Primary age of onset | 3–7 years | 11–17 years | 8–14 years |
| Sex predilection | Boys 4–5× more common | Girls 75–80% of cases | Boys slightly more common |
| Pain location | Medial midfoot (navicular) | Ball of foot under 2nd metatarsal | Posterior heel (Achilles insertion) |
| X-ray finding | Sclerotic, flattened navicular | Metatarsal head collapse / fragmentation | Dense, irregular calcaneal apophysis |
| Long-term prognosis | Excellent — usually full resolution | Variable — may need surgery in advanced stages | Excellent — resolves with skeletal maturity |
| Kohler Disease Treatment | When Used | Duration | Expected Outcome |
|---|---|---|---|
| Activity modification (reduce impact sports) | All cases | Until asymptomatic (typically 3–6 months) | Symptom control; allows natural revascularization |
| Arch-support insole or orthotic | Mild to moderate pain | Until resolution of symptoms | Offloads navicular; reduces pain with walking |
| Short-leg walking cast or CAM boot | Significant pain affecting daily activity | 4–8 weeks; longer if needed | Faster symptom resolution; bone remodeling unaffected |
| NSAIDS (symptom management) | Acute flares of pain | Short course as directed; not chronic | Temporary pain relief only |
| Surgery | Not typically indicated for Kohler disease | N/A | Disease is self-limiting; surgery rarely if ever needed |
Quick answer: Kohler Disease Foot is a clinical condition that responds to evidence-based treatment when caught early. Symptoms include pain, swelling, and altered function. Diagnosis requires clinical exam, often imaging. Treatment ladder: conservative care first (4-6 weeks), then targeted interventions if needed. Call (810) 206-1402.

What Is Köhler Disease?
Köhler disease is osteochondrosis (avascular necrosis) of the tarsal navicular bone in children. During a critical window of ossification, blood supply to the navicular is temporarily compromised — the bone becomes dense, flattened, and fragmented on X-ray before revascularizing and reshaping over 2–4 years.
It typically affects children ages 3–7, with boys more often than girls (5:1 ratio). It is usually unilateral but bilateral cases occur.
Symptoms
Children present with pain over the medial midfoot (navicular area), limping, and reluctance to walk. The pain often worsens with activity and improves with rest. Localized swelling and tenderness directly over the navicular are characteristic.
Diagnosis
Weight-bearing foot X-rays show a dense, flattened, or fragmented navicular — the classic “wafer” or “coin” sign. MRI confirms avascular changes before X-ray findings appear. The diagnosis requires correlation with clinical findings, since normal navicular ossification varies considerably.
Treatment
Conservative Management
Most cases respond well to activity modification and arch-supportive footwear or custom orthotics. NSAID therapy (ibuprofen) manages pain during flares.
Short Leg Walking Cast
For moderate-to-severe pain affecting daily activity, 4–6 weeks of short leg cast immobilization provides significant pain relief and appears to speed radiographic recovery.
Activity Restriction
Avoid high-impact sports during painful flares. Swimming and cycling maintain fitness without navicular loading.
Prognosis
Köhler disease is self-limiting — the navicular revascularizes spontaneously and remodels to a normal shape in nearly all cases. Long-term follow-up studies show no lasting foot deformity or functional disability in adulthood.
Frequently Asked Questions
How long does Köhler disease last?
Symptomatic phase typically lasts 6–18 months. Radiographic healing (navicular returning to normal density and shape) takes 2–4 years but usually outpaces symptoms.
Can Köhler disease come back?
Recurrence after full recovery is rare. Once the navicular has fully revascularized and remodeled, the condition does not recur.
