Calcaneal (Heel Bone) Fracture

Quick answer

A calcaneal fracture is a break in the heel bone — usually from a high-energy injury like a fall from height or a car crash. The heel bone bears huge loads, and damage to its joint surfaces causes long-term problems with arthritis. These are serious injuries with long recovery times.

Two distinct categories

High-energy fractures (most common)

• Fall from height landing on the heels — historically called a “lover’s fracture” from the trope of jumping out a window
• Motor vehicle crashes with the foot on the brake
• Almost always intra-articular — the fracture extends into the subtalar joint
• High rate of long-term subtalar arthritis

Stress fractures

• Repetitive impact in runners, military recruits, sometimes elderly people with weak bones
• No specific injury moment — gradual onset
• Generally better prognosis than acute high-energy fractures

Critical association

Falls from height with calcaneal fractures often have associated lumbar spine fractures. The same axial force that breaks the heel can compress vertebrae. Anyone with a calcaneal fracture from a fall needs spine evaluation as well. About 10% have a lumbar fracture.

How to recognize it

After a high-energy fall:

• Severe heel pain
• Inability to bear weight
• Significant swelling and bruising — bruising often spreads to the sole and arch
• Visible deformity — heel may look widened or shortened
• Heel may look bruised purple/black within hours

For stress fractures:

• Gradually increasing heel pain, worse with activity
• Swelling
• Tenderness when squeezing the sides of the heel
• Pain with weight-bearing

What happens at the hospital

Initial evaluation:

• X-rays in multiple views (lateral, axial)
• CT scan — almost always done for high-energy fractures; the gold standard for understanding fracture pattern
• Spine X-rays / CT if the mechanism was a fall from height
• Soft tissue assessment — significant swelling can compromise blood flow

The Sanders classification based on CT is used to grade intra-articular fractures and guide treatment.

Treatment

Non-displaced fractures

• Cast or boot for 6–8 weeks
• Strict non-weight-bearing for 8–12 weeks
• Gradual return to weight-bearing
• Physical therapy to restore range of motion and strength

Displaced intra-articular fractures (most common pattern)

The treatment debate here is real: surgery vs non-surgery. Outcomes are similar in many studies, with trade-offs:

• Surgery (open reduction with internal fixation):

  • Restores joint surface and heel shape
  • Reduces (but doesn’t eliminate) long-term arthritis risk
  • Higher complication rate — wound problems, infection, especially in smokers and diabetics
  • Recovery: non-weight-bearing for 8–12 weeks, full recovery 6–12 months

• Non-surgical:

  • Cast or boot, non-weight-bearing 8–12 weeks
  • Lower acute complications
  • Higher long-term need for subtalar fusion if arthritis develops

The decision depends on fracture pattern, age, smoking status, vascular health, and surgeon experience.

Severe / open fractures

• Emergency stabilization
• Definitive surgery once swelling has decreased (often days to weeks later)
• Tissue coverage sometimes needed for severely damaged skin

Recovery and long-term outlook

Calcaneal fractures are life-changing injuries. Realistic expectations:

• Full healing: 6–12 months
• Return to sedentary work: 3–4 months
• Return to physically demanding work: 6–12 months (sometimes never to pre-injury level)
• Subtalar arthritis develops in many patients — pain on uneven ground, after long days
• Subtalar fusion is sometimes needed years later for persistent arthritis

The high-energy versions are not minor injuries even when treated well.

When to see a clinician

Same day if you’ve:

• Fallen from height and can’t bear weight
• Severe heel pain after a car crash
• Significant heel swelling, deformity, or bruising
• Heel pain after any high-energy injury

Soon (within days) if:

• Heel pain with running or training that’s worsening over weeks (possible stress fracture)
• Pain with squeezing the sides of the heel
• Inability to walk normally despite no major injury

Prevention

For traumatic fractures: limited beyond general safety (fall prevention in older adults, proper safety equipment for high-risk work).

For stress fractures:

• Build training gradually
• Replace worn shoes
• Address bone health — adequate calcium, vitamin D, address menstrual irregularities in female athletes
• Don’t run through bone pain — early action prevents progression
