Sever's disease ,aka calcaneal apophysitis, is a common overuse injury in the pediatric and adolescent population.
Occurs secondary to traction of the calcaneus that most often occurs in young athletes (8-12 yo)
-Avg. age of presentation is 11 years 10 months in boys & 8 years 8 months in girls
-Repetitive traction to the weaker apophysis, induced by the pull of the Achilles on its insertion
Hx: Heel pain that increases with activity (running, jumping).
-May involve one (40%) or both (60%) feet
PE: Tenderness of the posterior heel at the Achilles tendon insertion and ankle dorsiflexor weakness
Imaging: Radiography is often normal. When positive, show fragmentation and sclerosis of the calcaneal apophsis. NOTE: These findings are nonspecific and also are observed in asymptomatic feet.
Tx: Rest from aggravating activities, NSAIDs, ice (both pre and post sport). When pain free a program of stretching (gastrocnemius-soleus), strengthening (dorsiflexors) and shoe inserts (heel cups, lifts, pads, or orthotics) can provide significant pain relief.
