A calcaneal growth plate fracture is a break in the heel bone’s growth region, requiring timely diagnosis and careful treatment to avoid long-term issues.
Anatomy and Importance of the Calcaneal Growth Plate
The calcaneus, or heel bone, is a key structure in the foot that absorbs impact and supports body weight during walking and running. In children and adolescents, the calcaneus contains a growth plate—known medically as the calcaneal apophysis—which is a zone of developing cartilage near the back of the heel. This growth plate allows the bone to lengthen as the child grows.
Unlike adult bones that are fully ossified (turned into solid bone), growth plates are softer and more vulnerable to injury. The calcaneal growth plate plays a pivotal role in shaping the heel’s size and strength during development. Damage to this area can disrupt normal bone growth, leading to deformities or chronic pain if not properly managed.
Mechanism Behind Calcaneal Growth Plate Fractures
A calcaneal growth plate fracture typically occurs due to sudden trauma or repetitive stress. Common causes include:
- Falls from height: Landing on the feet after jumping or falling can transmit high forces through the heel.
- Sports injuries: Activities involving running, jumping, or abrupt stops place stress on the heel, especially in young athletes.
- Direct impact: A heavy object striking the heel can cause a fracture.
The injury mechanism often involves excessive traction or compression forces on the apophysis. Because this region is weaker than mature bone, it absorbs more strain during such impacts, making it prone to fractures.
The Difference Between Fractures and Sever’s Disease
It’s important to distinguish a calcaneal growth plate fracture from Sever’s disease (calcaneal apophysitis). Sever’s disease is an inflammation of the growth plate caused by repetitive microtrauma rather than an actual break. While symptoms may overlap—heel pain and tenderness—the treatment approaches differ significantly.
Symptoms Indicating a Calcaneal Growth Plate Fracture
Symptoms usually develop immediately following trauma but can sometimes present gradually if caused by repetitive stress. Key signs include:
- Pain: Sharp or aching pain localized at the back or bottom of the heel, worsening with weight-bearing activities.
- Swelling: Noticeable swelling around the heel area.
- Tenderness: Sensitivity when pressing over the calcaneal apophysis.
- Limping or refusal to bear weight: Especially in younger children who may avoid using the affected foot.
- Reduced ankle motion: Due to pain and swelling.
If left untreated, symptoms might escalate into chronic discomfort or gait abnormalities.
Diagnostic Techniques for Accurate Identification
Confirming a calcaneal growth plate fracture requires thorough clinical evaluation paired with imaging studies:
X-rays
Plain radiographs remain the first-line imaging tool. They reveal disruptions in bone continuity and any displacement of fragments within the growth plate region. However, subtle fractures may be missed due to overlapping structures.
MRI (Magnetic Resonance Imaging)
MRI offers detailed visualization of cartilage, soft tissues, and bone marrow edema. It helps differentiate fractures from inflammation (like Sever’s disease) and detects occult injuries not visible on X-rays.
Ultrasound
In some cases, ultrasound can assess soft tissue swelling and detect fluid collections around the heel but is less definitive for fractures.
| Imaging Modality | Main Advantage | Limitations |
|---|---|---|
| X-ray | Widely available; shows clear bone fractures | Might miss subtle cracks; limited soft tissue detail |
| MRI | Differentiates fracture from inflammation; shows cartilage injury | Expensive; less accessible; longer scan time |
| Ultrasound | No radiation; good for soft tissue assessment | Poor visualization of bone; operator-dependent results |
Treatment Pathways for Calcaneal Growth Plate Fractures
Treatment strategies focus on stabilizing the fracture site while preserving normal bone development.
Non-Surgical Management
Most calcaneal growth plate fractures are treated conservatively unless severely displaced. Key components include:
- Immobilization: A cast or walking boot restricts movement to allow healing.
- Pain control: NSAIDs such as ibuprofen reduce inflammation and discomfort.
- Limb elevation: Helps minimize swelling during acute phases.
- Lifestyle modification: Avoidance of high-impact activities until healing completes.
Healing typically takes 4-6 weeks depending on severity. Follow-up X-rays assess progress.
Surgical Intervention
Surgery becomes necessary when:
- The fracture fragments are widely displaced (>2 mm).
- The growth plate is severely disrupted risking deformity.
- The injury fails to heal with conservative care (nonunion).
Surgical goals include realigning fragments and stabilizing them using screws or pins without damaging remaining growth potential.
Postoperative care involves immobilization followed by gradual rehabilitation focusing on restoring ankle range of motion and strength.
Pitfalls and Complications of Untreated Injuries
Ignoring or misdiagnosing a calcaneal growth plate fracture can lead to several long-term problems:
- Bony deformity: Improper healing may cause abnormal heel shape affecting foot mechanics.
- Limb length discrepancy:If one heel grows slower than its counterpart due to physeal damage.
- Persistent pain:A chronic source of discomfort limiting physical activity.
- Tendon issues:The Achilles tendon attaches near this area; altered anatomy can cause tendinopathy.
These complications highlight why early recognition matters so much in pediatric foot injuries.

Frequently Asked Questions
What is a Calcaneal Growth Plate Fracture?
A calcaneal growth plate fracture is a break in the heel bone’s growth region, known as the calcaneal apophysis. This injury occurs in children and adolescents and requires prompt diagnosis to prevent long-term complications related to bone growth and heel function.
How does a Calcaneal Growth Plate Fracture occur?
This fracture typically results from sudden trauma or repetitive stress. Common causes include falls from height, sports injuries involving running or jumping, and direct impacts to the heel. The growth plate is softer than mature bone, making it vulnerable to these forces.
What are the symptoms of a Calcaneal Growth Plate Fracture?
Symptoms include sharp or aching pain at the back or bottom of the heel, swelling, tenderness over the growth plate area, and difficulty bearing weight. Limping or refusal to walk may also occur, especially in younger children following trauma.
How is a Calcaneal Growth Plate Fracture different from Sever’s Disease?
While both affect the heel’s growth plate region, a fracture is a break in the bone, whereas Sever’s disease is inflammation caused by repetitive microtrauma. Treatment differs as fractures require immobilization, while Sever’s disease focuses on rest and reducing inflammation.
What treatments are recommended for a Calcaneal Growth Plate Fracture?
Treatment involves timely immobilization to allow proper healing and prevent deformities. This may include casting or splinting and avoiding weight-bearing activities. Follow-up care ensures normal bone growth and reduces the risk of chronic pain or long-term issues.
The Role of Rehabilitation After Healing
Once immobilization ends, rehabilitation plays a critical role in full recovery:
- Pain management continues with gentle stretching exercises.
- Ankle strengthening improves stability around the heel joint.Balanace training reduces risk of re-injury during sports participation.A gradual return-to-play program ensures safe resumption of activities without overloading healing tissues.
Physical therapy guidance tailored for children accelerates regaining normal function while minimizing setbacks.
Navigating Recovery: What To Expect Timeline-Wise?
Recovery from a calcaneal growth plate fracture varies depending on factors like age, injury severity, and treatment type. Here’s a general timeline:
- 0-6 weeks : Immobilization phase where rest is crucial; swelling decreases progressively .
- 6-12 weeks : Gradual weight bearing begins ; physical therapy starts focusing on ankle mobility .
- 12+ weeks : Full activity restoration ; ongoing strength & balance exercises .
- Long-term : Monitoring for any residual deformities or functional deficits .
Patience is key—rushing back too soon risks setbacks or incomplete healing.
