The calcaneal apophysis is a growth center where
the Achilles tendon and the plantar fascia attach to the heel. It first appears
in children aged 7 to 8 years. By ages 12 to 14 years the growth center matures
and fuses to the heel bone.
Injuries can occur from excessive tension on the
Achilles tendon and the plantar fascia, or from direct impact on the heel.
Excessive stress on this growth center can cause irritation of the heel, also
called Sever’s disease.
Athletes with Sever’s disease are
typically aged 9 to 13 years and participate in running or jumping sports such
as soccer, football, basketball, baseball, and gymnastics. The typical complaint
is heel pain that develops slowly and occurs with activity. The pain is usually
described like a bruise. There is rarely swelling or visible bruising. The pain
is usually worse with running in cleats or shoes that have limited heel lift,
cushion, and arch support. The pain usually goes away with rest and rarely
occurs with low-impact sports such as bicycling, skating, or swimming.
A physical exam of the heel will show tenderness
over the back of the heel but not in the Achilles tendon or plantar fascia.
There may be tightness in the calf muscle, which contributes to tension on the
heel. The tendons in the heel get stretched more in patients with flat feet.
There is greater impact force on the heels of athletes with a high-arched, rigid
The doctor may order an x-ray because x-rays can
confirm how mature the growth center is and if there are other sources of heel
pain, such as a stress fracture or bone cyst. However, x-rays are not necessary
to diagnose Sever’s disease, and it is not possible to make the diagnosis
based on the x-ray alone.
Heel pain can also be caused by a stress
fracture in the heel, bursitis, tendonitis, bone cysts, and rheumatologic
disorders. If the athlete is not active in impact sports or is not between age 9
and 13 years, other conditions should be considered.
The following are different treatment
Rest and modify activity.
Limit running and high-impact activity to rest the heel and lessen the
pain. Choose one running or jumping sport to play at a time. Substitute
low-impact cross-training activities to maintain cardiovascular fitness.
This can include biking, swimming, using a stair-climber or elliptical
machine, rowing, or inline skating.
Reduce inflammation. Ice
for at least 20 minutes after activity or when pain increases.
Nonsteroidal anti-inflammatory drugs (NSAIDs) may also help.
Stretch the calf. Increase
calf flexibility by doing calf stretches for 30 to 45 seconds several
times per day.
Protect the heel. The shoe
may need to be modified to provide the proper heel lift or arch support.
Select a shoe with good arch support and heel lift if possible. Try heel
lifts or heel cups in sports shoes, especially cleats. Try arch support
in cleats if flat feet contribute to the problem.
Take it one step at a time.
Gradually resume running and impact activities as symptoms allow.
Sever’s disease usually goes away when
the growth plate (apophysis) matures, which should be by age 12 to 13 years in
females and 13 to 14 years in males.
