Calcaneal Apophysitis

Calcaneal Apophysitis

Definition

Calcaneal Apophysitis is a painful inflammation of the heel’s growth plate. It typically affects children between the ages of 8 and 14 years old because the heel done (calcaneus) is not fully developed until at least age 14. Until then, new done is forming at the growth plate, a weak area located at the back of the heel. When there is too much repetitive stress on the growth plate, inflammation can develop.

Overview:

    • Occurs in juveniles
    • Pathomechanics for calcaneal apophysitis are exactly the same as for Achilles tendonitis.
    • However, in apophysitis, the weak link is the attachment of the calcaneal apophysis to the calcaneus (heel bone) (not the tendon to the calcaneus, as in Achilles tendinitis).

Treatment:

    • Heel lift of 9mm or greater
    • Soft supportive orthotic
    • Severe cases may require cast immobilization.
