It commonly occurs in children between the ages of 8-13 years. Pain generally worsens on activity, and may be evident behind the heel or radiating up both sides.
The condition runs a course of approximately 1-2 years, then the bone spontaneously re-hardens. Treatment involves minimising deformity during this period.
Treatment options:
Modified activity (rest)
Ice/Massage/Stretching
Heel lift or wedge
Padding
Footwear advice
Orthotics
