Sever’s disease — medically known as calcaneal apophysitis — is the most common cause of heel pain in children, particularly those aged 8–14 years. It occurs during periods of rapid growth when the heel bone (calcaneus) is still developing and the growth plate is vulnerable to stress. Because Melbourne children are often active in sports like AFL, basketball, soccer, and netball, this condition is frequently seen in clinical practice. Sever’s disease is not a true “disease” but an overuse injury of the heel’s growth plate, and although painful, it is self?limiting and resolves fully once growth is complete.

Sever’s disease is an inflammatory condition of the calcaneal growth plate, triggered when repetitive traction forces from the Achilles tendon pull on the still?soft apophysis. Because the growth plate is weaker than mature bone, it becomes irritated easily during high?impact activities.

Authoritative sources describe it as a common cause of heel pain in childhood, especially in active children who run and jump frequently

Why It Happens: Growth, Biomechanics, and Overuse

During a child’s growth spurt, the tibia and fibula lengthen rapidly, often faster than the calf muscles and Achilles tendon can adapt. This creates tightness in the posterior chain, increasing traction on the heel’s growth plate.

Key contributing factors include:

• High?impact sports such as soccer, basketball, netball, gymnastics, and AFL
• Running on hard surfaces
• Poorly cushioned or studded footwear
• Tight calf muscles
• Flat feet or high arches, which alter heel loading patterns
• Rapid growth spurts, especially between ages 8–12

The Sydney Children’s Hospitals Network highlights that activities involving running, jumping, and back?and?forth heel movements are particularly provocative

Clinical Presentation: How Sever’s Disease Appears

Children typically report:

• Heel pain, especially during or after sport
• Tenderness when the sides of the heel are squeezed
• Mild swelling or redness
• Limping, especially after activity
• Stiffness in the morning
• Pain when running, jumping, or walking barefoot

Symptoms may affect one or both heels and often worsen with increased activity.

Diagnosis

Diagnosis is clinical, based on history and physical examination.

Doctors typically:

• Palpate the heel for tenderness
• Perform the squeeze test of the calcaneus
• Assess calf tightness and foot posture
• Evaluate gait

X?rays are not usually required, as they rarely change management and growth plates normally appear irregular on imaging.

Management and Treatment

Sever’s disease is self?limiting, but symptoms can last months or even recur over several years. Treatment focuses on reducing pain, improving biomechanics, and modifying activity.

1. Activity Modification

Temporarily reducing or stopping painful activities is the first step.
Running, jumping, and high?impact sports may need to be limited, while low?impact activities like swimming or cycling are encouraged.

2. Ice Therapy

Applying ice for 20 minutes after activity reduces inflammation.

3. Footwear and Orthotic Support

Supportive, well?cushioned shoes are essential.
Helpful additions include:

• Gel heel cups (eg the Tulis) or heel raises to reduce Achilles traction
• Avoiding studs or hard?soled shoes
• Ensuring proper fit and shock absorption

These strategies are widely recommended across paediatric orthopaedic guidelines

4. Stretching and Strengthening

Calf stretching is one of the most effective treatments.
Daily exercises reduce tension on the growth plate.

Strengthening intrinsic foot muscles and improving ankle mobility can also help restore normal biomechanics.

5. Physiotherapy

A physiotherapist may:

• Prescribe stretching and strengthening programs
• Address gait abnormalities
• Provide manual therapy
• Guide return?to?sport planning

SCHN notes that physiotherapy is particularly helpful when symptoms are persistent or severe

6. Pain Relief

Short?term use of paracetamol or ibuprofen may be appropriate, though medication is rarely essential.

Prognosis

Sever’s disease is benign and temporary.
Symptoms typically resolve within 6–12 months, though some children experience intermittent flare?ups for up to 2 years.

Prevention and Long?Term Management

While Sever’s disease cannot always be prevented, risk can be reduced through:

• Regular calf stretching, especially during growth spurts
• Wearing supportive footwear
• Avoiding excessive training loads
• Gradual progression in sports intensity
• Taking breaks during repetitive activities
• Strengthening lower?limb muscles
• Avoiding running on hard surfaces

Differential Diagnosis

Other conditions that may mimic or coexist with Sever’s disease include:

• Achilles tendinopathy
• Plantar fasciitis
• Stress fractures of the calcaneus
• Juvenile idiopathic arthritis
• Bursitis

Sever’s disease is a common, self?limiting cause of heel pain in children, especially those involved in high?impact sports. It results from repetitive stress on the heel’s growth plate during periods of rapid growth. Although painful, it is not harmful, and children recover fully with appropriate management.

Treatment focuses on activity modification, stretching, supportive footwear, and symptom relief. With proper care, children can safely return to sport and continue normal activities without long?term consequences.
