Sever's Disease Treatment Richmond & Kensington

Overview

What Is Sever's Disease?

Sever's disease — also known as calcaneal apophysitis — is the most common cause of heel pain in children and adolescents. It is an overuse injury affecting the calcaneal apophysis, the growth plate at the back of the heel bone where the Achilles tendon attaches. During periods of rapid growth, this growth plate is particularly vulnerable to the repetitive traction forces generated by the Achilles tendon and calf muscles during walking, running and jumping.

Despite its name, Sever's disease is not a disease — it is a self-limiting condition that resolves naturally once the growth plate fuses, typically between the ages of 14 and 16. However, without appropriate management, it can cause significant pain and restrict a child's participation in sport and physical activity for months or years during its active phase. With the right treatment, most children can remain active and their symptoms can be substantially reduced.

Good news for parents: Sever's disease is temporary. It resolves completely once the growth plate closes — no child carries it into adulthood. The goal of treatment is to manage pain and maintain activity during the symptomatic phase, not to fix a permanent problem.

Why the Growth Plate Is Vulnerable

The calcaneal apophysis is a secondary ossification centre — a section of cartilage at the back of the heel that is in the process of converting to bone during childhood and adolescence. During a growth spurt, the bones lengthen faster than the surrounding muscles and tendons, causing the Achilles tendon and calf complex to become relatively tight and to exert greater traction force on the still-soft growth plate.

In active children — particularly those playing football, running or doing gymnastics — this traction force is applied repetitively with every footstrike. Over time, the cumulative stress exceeds the growth plate's tolerance, causing microtrauma, inflammation and pain at the back of the heel.

The growth plate fuses completely between ages 14–16, at which point the structural vulnerability disappears and Sever's disease cannot recur.

Risk Factors

Rapid growth spurt — bones outpacing tendons High training volume or sudden increase in sport Tight calf muscles and Achilles tendon Flat feet — increased traction on the calcaneus High-arched feet — reduced shock absorption Hard playing surfaces — increased impact loading Worn or poorly cushioned footwear Football boots without adequate heel cushioning Overweight — increased load through the heel Male sex — slightly higher prevalence overall

Symptoms

Signs & Symptoms of Sever's Disease

What to Look For

Pain at the back of the heel — one or both sides Pain that worsens during or after sport Tenderness on squeezing the heel from the sides Limping during or after activity Walking on tiptoes to avoid heel contact Stiffness and aching in the heel first thing in the morning Pain that eases with rest but returns with activity Reluctance to participate in sport or PE

The Squeeze Test

The most reliable clinical sign of Sever's disease is a positive squeeze test — pain reproduced by applying medial and lateral compression to the back of the heel simultaneously. This is highly specific to calcaneal apophysitis and is the primary clinical confirmation used in assessment.

Imaging is rarely needed to diagnose Sever's disease. X-ray findings are unreliable as the growth plate appearance varies considerably between children and does not correlate with symptom severity. The diagnosis is clinical.

A key differentiating feature from adult plantar heel pain is the location — Sever's pain is at the very back and sides of the heel, not under the heel on the plantar surface.

Differential diagnosis

Other Causes of Heel Pain in Children

Sever's disease is by far the most common cause of heel pain in children aged 8–14, but the following should always be considered — particularly if the presentation is atypical.

Plantar Fasciitis

Plantar fasciitis causes pain on the plantar (under) surface of the heel, typically worst with the first steps in the morning. Less common in children than adults but does occur, particularly in adolescents with flat feet. Distinguished from Sever's by the location of pain — plantar rather than posterior — and a negative squeeze test.

Achilles Tendinopathy

Tendinopathy of the Achilles tendon produces pain along the tendon above the heel insertion, with tenderness to palpation along the tendon body. Less common in younger children but occurs in adolescents, particularly runners. Distinguished from Sever's by pain location — mid-tendon or insertional rather than at the growth plate.

Stress Fracture of the Calcaneus

A calcaneal stress fracture produces diffuse heel pain with a positive squeeze test — making it potentially difficult to distinguish from Sever's clinically. Should be suspected if pain is severe, constant or present at rest, or if there has been a significant increase in training load. MRI is the gold standard if stress fracture is suspected.

Retrocalcaneal Bursitis

Inflammation of the bursa between the Achilles tendon and the calcaneus produces posterior heel pain with localised swelling just above the heel bone. More common in adolescents than younger children. Distinguished by swelling visible and palpable just above the heel — absent in uncomplicated Sever's disease.

Treatment

Our Approach to Treating Sever's Disease

The goal of treatment is to reduce traction load on the calcaneal growth plate, manage pain, and allow the child to remain as active as possible while symptoms settle. Complete rest is rarely necessary or helpful — a structured, activity-modified approach produces better outcomes and keeps children engaged in sport. Most cases respond well to conservative management within 2–8 weeks.

Clinical Assessment & Diagnosis

A thorough assessment including squeeze test, assessment of ankle dorsiflexion range, calf muscle tightness, foot posture and gait analysis. We document the severity of symptoms, identify contributing biomechanical factors and establish a clear diagnosis. We assess footwear — particularly football boots and trainers — at the same appointment, as poor heel cushioning is one of the most modifiable risk factors.

Heel Raises & Cushioning

A heel raise — typically 6–10mm — within the shoe reduces the traction angle of the Achilles tendon on the growth plate and is one of the most immediately effective interventions for Sever's disease. We provide gel heel cups or felt raises and guide parents on correct insertion. For football players, a heel raise inside the boot combined with a cushioned insole beneath it can allow return to sport with significantly reduced symptoms.

Calf Stretching Programme

A structured twice-daily calf and Achilles stretching programme reduces the resting tension in the calf complex, directly reducing the traction force on the growth plate. We prescribe both gastrocnemius and soleus stretches — the two components of the calf that must both be targeted for effective load reduction. Written instructions are provided and progress is monitored at follow-up. This is the single most important home management component.

Custom Orthotics

For children whose Sever's disease is associated with flat feet or excessive pronation — which increases tensile load on the Achilles — custom orthotics addressing the foot mechanics provide longer-term load reduction beyond the heel raise alone. They also improve footwear fit and stability. Prescribed following gait analysis and foot posture assessment where biomechanical correction is clinically indicated rather than as a default response.

Activity Modification

Rather than complete rest, we prescribe a graded activity modification plan — reducing the volume and impact of sport to a level below the symptom threshold, then progressively reintroducing it as symptoms settle. This keeps children active, prevents deconditioning and maintains motivation. Switching temporarily to lower-impact activities such as swimming or cycling can maintain fitness during the recovery phase without aggravating the growth plate.

Footwear Guidance

We review all footwear worn for sport and daily activities, providing specific guidance on appropriate heel height, cushioning, heel counter support and fit. Football boots — often worn with no insole and minimal cushioning — are a significant contributing factor and require specific attention. We advise on the most appropriate boots for the child's foot type and recommend insole additions where standard boot insoles are insufficient.

Strengthening & Return to Sport

As symptoms settle, a progressive lower limb strengthening programme — targeting calf strength, ankle stability and intrinsic foot muscles — improves load tolerance and reduces recurrence risk during subsequent growth spurts. We provide a structured return-to-sport plan with clear criteria for progression, ensuring the child resumes full training at a pace that maintains symptom control.

FAQs

Common Questions About Sever's Disease

Does my child need to stop playing sport?

Not necessarily — and for most children, complete rest is not the right answer. The goal is to find the level of activity at which symptoms are manageable and train at or below that level while implementing heel raises, stretching and footwear modifications. Many children can continue playing with reduced symptoms using these measures alone. Where pain is severe or not responding, a short period of relative rest may be needed, but return to sport is always the aim.

Will Sever's disease come back?

It can recur during subsequent growth spurts within the same growth plate closure period, particularly if the underlying contributing factors — tight calves, poor footwear, flat feet — have not been addressed. Once the growth plate fuses (typically age 14–16), Sever's disease cannot recur. Managing the biomechanical risk factors reduces the likelihood of recurrence during the active phase.

How long does Sever's disease last?

Individual episodes typically settle within 2–8 weeks with appropriate management. However, symptoms can recur during subsequent growth spurts, meaning a child may experience intermittent episodes from age 8 through to 14–15 when the growth plate closes. Each episode should be managed actively rather than waited out, as unmanaged Sever's disease can significantly restrict activity for months at a time.

Can Sever's disease affect both heels?

Yes — bilateral involvement occurs in approximately 60% of cases. One heel is often more painful than the other, but both should be assessed and managed. If only one heel is symptomatic, the opposite side should still be examined as subclinical involvement is common and can become symptomatic as load shifts to compensate for the painful side.

Do I need an X-ray?

X-rays are not routinely needed to diagnose Sever's disease. The diagnosis is clinical, based on the squeeze test and history. X-ray findings — including the appearance of the growth plate — do not correlate reliably with symptoms and can be misleading. We request imaging only if the presentation is atypical or if a stress fracture or other pathology needs to be excluded.

Is treatment covered by health insurance?

Yes — podiatry consultations are typically covered by most major insurers. We work with Bupa, Aviva, WPA and others. See our insurance page for full details.
