Navicular is temporarily ‘softened’ and compressed by weightbearing forces. Most commonly ages 3 to 9. M>F. Usually unilateral. Have vague pain and tenderness localised over navicular – also can limp and avoid active inversion. On x-ray get characteristic narrowing of navicular with an irregular increase in density – this deformity is very pronounced.
Acute stage – nonweightbearing
Mild – activity modification and foot orthoses to protect structural alignment
Severe – below knee cast
