How To Tell If Your Heel Is Broken: Clinical Signs And Assessment
A broken heel, or calcaneal fracture, typically results from high-energy trauma such as a fall from a height or a vehicular collision, causing severe posterior foot pain, immediate swelling, and an inability to bear weight. Differentiating a severe soft-tissue sprain from an osseous injury requires evaluating localized mechanical tenderness, structural deformity, and functional gait failure.
Pre-Assessment and Triage Protocol
Recognizing a calcaneal fracture quickly prevents secondary displacement of bone fragments and minimizes neurovascular compromise. Before attempting any physical examination, prepare a controlled environment and basic diagnostic support gear.
- Essential Assessment Tools: Ice packs, sterile compression bandages, rigid splinting materials, and a non-flexible walking surface for testing weight-bearing capacity (only if minor injury is suspected).
- Prerequisite Knowledge: The calcaneus is the largest tarsal bone, absorbing significant ground reaction forces. Fractures often extend into the subtalar joint, meaning structural instability demands immediate orthopedic intervention rather than conservative home management.
- Time and Cost Benchmarks: Immediate triage takes less than 10 minutes. Diagnostic imaging (X-ray or CT scan) and subsequent orthopedic consultation should occur within 24 to 48 hours to prevent long-term functional loss.
Step-by-Step Diagnostic Assessment
Step 1: Evaluate the Immediate Mechanism of Injury
- Review how the trauma occurred. Calcaneal fractures overwhelmingly stem from axial loading injuries, such as landing squarely on the heels after falling from a ladder or jumping from an elevated surface.
- Assess whether rotational forces accompanied the impact, as this increases the likelihood of intra-articular damage affecting the subtalar joint.
Warning: Do not attempt to force the foot into a neutral position if a visible dislocation or extreme angulation is present, as this can sever surrounding blood vessels or nerves.
Step 2: Assess Weight-Bearing Capacity
- Test the ability to take even a single step on the affected foot. A complete inability to bear weight (axial loading intolerance) is one of the most reliable clinical indicators of a major structural fracture.
- Differentiate between pain-limited weight-bearing (common in severe contusions or minor hairline fractures) and mechanical collapse where the structural integrity of the heel arch is compromised.
Pro-Tip: If the patient can take four consecutive steps without extreme, sharp pain, a complete displaced fracture is less likely, though stress fractures or soft-tissue tears remain possible.
Step 3: Inspect for Visual Deformity and Swelling
- Examine the heel for widening, shortening, or a flattened appearance compared to the uninjured foot. A broken calcaneus frequently expands laterally, making the heel look noticeably wider.
- Look for "Mondor's sign," which manifests as bruising that extends down the sole of the foot toward the toes, indicating deep hematoma formation from the fractured bone.
- Check for skin tenting, where sharp bone fragments push upward against the dermis, threatening tissue necrosis.
Step 4: Palpate for Bony Tenderness
- Gently press along the posterior aspect of the heel, specifically targeting the Achilles tendon insertion and the medial and lateral borders of the calcaneus.
- Perform the "squeeze test" by gently compressing the sides of the heel simultaneously. Severe, sharp pain elicited by lateral compression is a hallmark clinical sign of a calcaneal fracture.
- Check the range of motion of the ankle. While ankle dorsiflexion and plantarflexion may remain intact, subtalar inversion and eversion will typically cause excruciating pain if the calcaneus is broken.

Clinical Comparison of Heel Injuries
| Injury Type | Primary Symptom | Weight-Bearing Ability | Visual Appearance | Standard Clinical Diagnosis |
|---|---|---|---|---|
| Calcaneus Fracture | Severe posterior foot pain, throbbing ache | Zero to minimal | Widened heel, plantar bruising | Lateral/Axial X-rays and CT scan |
| Plantar Fasciitis | Sharp heel pain, worst on first steps | Possible with a limp | Normal contours | Clinical history and palpation |
| Achilles Tendon Rupture | Sudden pop, pain in lower calf | Impaired push-off, weak flexion | Gap above heel, Thompson test positive | Clinical exam and diagnostic ultrasound |
| Severe Heel Contusion | Localized bruising and surface pain | Painful but possible | Localized swelling, normal width | Physical exam, ruling out fracture via X-ray |
Common Diagnostic Challenges and Field Fixes
- Failure Scenario: Confusing a calcaneus fracture with a severe ankle sprain due to generalized swelling around the hindfoot.
- Root Cause: Proximity of the subtalar joint to the ankle joint often leads to overlapping edema that masks the exact origin of pain.
- Actionable Fix: Isolate palpation strictly to the bone structures of the heel rather than the lateral ankle ligaments; if lateral squeeze causes severe pain, treat it as a potential calcaneal injury and immobilize.
- Failure Scenario: Ignoring delayed bruising on the sole of the foot because the initial skin surface appeared normal.
- Root Cause: Deep internal bleeding from cancellous bone takes several hours to migrate through thick plantar fascia and subcutaneous fat.
- Actionable Fix: Re-evaluate the foot 12 to 24 hours post-injury; appearance of plantar ecchymosis warrants an immediate professional orthopedic evaluation.
Frequently Asked Questions
Can you walk on a broken heel?
In rare cases of non-displaced or hairline stress fractures, individuals may manage limited, agonizing weight-bearing. However, with a displaced calcaneal fracture, walking is virtually impossible due to the structural collapse of the heel bone and intense mechanical pain.
How do doctors confirm a broken heel?
Clinicians use standard radiographic imaging, including lateral, axial, and anteroposterior foot and ankle X-rays, to visualize the bone architecture. A computed tomography (CT) scan is routinely ordered afterward to map out intra-articular involvement and surgical planning.
What is Bohler's angle and why does it matter?
Bohler's angle is a measurement calculated on a lateral X-ray to assess the structural integrity of the calcaneus. A normal angle ranges between 25 and 40 degrees; a flattening or depression below this range confirms a significant fracture requiring reduction.
When should I go to the emergency room for heel pain?
Seek immediate emergency medical care if you experience an inability to bear weight, severe swelling, visible foot deformity, numbness or tingling in the sole, or an open wound near the heel exposing bone.
Professional Orthopedic Evaluation and Care
Determining whether your heel is broken requires prompt clinical imaging and expert orthopedic assessment to preserve long-term mobility and joint function. Schedule an appointment with a foot and ankle specialist immediately if you suspect a calcaneal injury to discuss customized immobilization, reduction, or surgical options.
