The heel bone is formally known as the calcaneus, which forms the foundation of the rear foot. This sturdy bone connects the leg to the foot and plays a key role in walking, running, and weight distribution.
Understanding the name and function of the calcaneus helps people identify sources of heel pain and choose appropriate footwear and treatment. The sections below explore its anatomy, common conditions, and practical steps for care.
| Feature | Anatomical Detail | Function | Clinical Relevance |
|---|---|---|---|
| Bone Name | Calcaneus | Forms the heel | Common site for fractures and stress injuries |
| Joint Surface | Subtalar joint with the talus | Enables inversion and eversion | Injury can lead to chronic instability |
| Attachment Points | Insertion for Achilles tendon and plantar fascia | Transfers force during push-off | Overload causes Achilles tendinopathy and plantar fasciitis |
| Blood Supply | Posterior tibial artery branches | Nourishes bone and soft tissue | Compromised circulation slows healing after fracture |
Structure of the Calcaneus in the Skeletal System
The calcaneus is the largest tarsal bone and sits directly beneath the talus, forming the heel prominence. Its robust shape absorbs impact when the foot strikes the ground.
Articular surfaces allow smooth movement at the subtalar joint, which is essential for adapting to uneven terrain. Ligaments and muscles attach around the calcaneus to stabilize the ankle and foot.
Common Conditions Affecting the Heel Bone
Several conditions can involve the calcaneus, often causing pain in the heel or surrounding areas. Recognizing early signs supports timely intervention and reduces the risk of long-term problems.
- Calcaneal stress fractures from repetitive loading
- Sever’s disease in growing athletes due to traction on the growth plate
- Insertional Achilles tendinopathy where the tendon joins the bone
- Subtalar joint arthritis affecting motion and comfort
Diagnosis and Imaging of Heel Bone Issues
Clinicians evaluate heel pain through physical tests and imaging. Weight-bearing views and specialized angles help visualize the calcaneus alignment and joint spaces.
Imaging choices may include X-rays, ultrasound, or advanced modalities to confirm fractures, inflammation, or degenerative changes. Accurate diagnosis guides targeted treatment and prevention strategies.
Treatment, Rehabilitation, and Prevention
Management of calcaneus-related problems often combines rest, targeted exercises, and supportive devices. Physical therapy can strengthen the surrounding muscles and improve joint control.
Footwear with proper cushioning and arch support reduces strain on the heel bone. Gradual progression in activity load helps prevent overuse injuries and supports long-term foot health.

FAQ
Reader questions
What is the medical name for the heel bone?
The medical name for the heel bone is the calcaneus.
Why is the calcaneus important for walking and running?
The calcaneus acts as a shock absorber and provides a stable base for the foot during gait, helping transmit forces between the leg and the ground.
What are common injuries related to the calcaneus?
Common injuries include calcaneal stress fractures, Sever’s disease, insertional Achilles tendinopathy, and subtalar joint arthritis.
How can I protect my heel bone during exercise?
You can protect your heel bone by wearing supportive shoes, gradually increasing training intensity, incorporating strength and flexibility work, and addressing pain early.
