Bone Spur of the Calcaneus

Overview

Bone spurs of the calcaneus, commonly referred to as heel spurs, are calcium carbonate deposits that form as pointed, hook-like, or shelf-like bony projections on the heel bone. These osteophytes develop as the body's natural response to chronic mechanical stress, inflammation, and tissue damage in the foot. The calcaneus, being the largest bone in the foot and bearing significant weight-bearing loads, is particularly susceptible to these formations.

There are two primary types of calcaneal bone spurs: plantar calcaneal spurs, which develop on the underside of the heel where the plantar fascia attaches, and posterior calcaneal spurs, which form at the back of the heel where the Achilles tendon inserts. Plantar spurs are more common and are frequently associated with plantar fasciitis, while posterior spurs are often linked to Achilles tendonitis or insertional Achilles tendinopathy.

The formation of heel spurs is a gradual process that occurs over months to years. Chronic tension and micro-tears in the plantar fascia or Achilles tendon lead to inflammation at their attachment sites on the calcaneus. As part of the healing process, the body deposits calcium at these stress points, eventually forming the characteristic bony projections. Interestingly, many people develop heel spurs without experiencing any symptoms, and the spurs are often discovered incidentally on imaging studies performed for other reasons.

The prevalence of calcaneal bone spurs increases with age, affecting approximately 10-15% of the general population, with higher rates seen in individuals over 40 years old. They are more common in women than men and are frequently bilateral, although symptoms may be more pronounced in one foot. While heel spurs themselves are often painless, they can contribute to chronic heel pain when associated with inflammation of surrounding soft tissues, making proper diagnosis and management essential for maintaining quality of life and mobility.

Symptoms

The symptoms of calcaneal bone spurs can vary significantly from person to person. Many individuals with heel spurs experience no symptoms at all, while others may have debilitating pain that significantly impacts their daily activities and quality of life.

Primary Symptoms

• Foot or toe pain - Sharp, stabbing heel pain, especially in the morning
• Ankle pain - Discomfort extending from the heel to the ankle region
• Leg pain - Pain may radiate up the leg due to altered gait mechanics
• Foot or toe swelling - Inflammation around the heel and arch area
• Elbow pain - May occur due to compensatory movements when using walking aids

Causes

Calcaneal bone spurs develop as a result of chronic mechanical stress, inflammation, and the body's attempt to stabilize and repair damaged tissue. Understanding these underlying causes is crucial for effective treatment and prevention strategies.

Primary Mechanical Causes

Plantar Fascia Stress

The plantar fascia is a thick band of connective tissue that supports the arch of the foot. Chronic tension and micro-tears in this structure lead to inflammation at its attachment point on the calcaneus:

• Excessive tension: Repetitive stretching beyond normal tissue limits
• Micro-trauma: Small tears that accumulate over time
• Inflammatory response: Body's attempt to heal damaged tissue
• Calcium deposition: Formation of bone spurs as a stabilization mechanism
• Biomechanical dysfunction: Altered foot mechanics increasing stress on the fascia

Achilles Tendon Stress

Posterior calcaneal spurs develop due to chronic stress at the Achilles tendon insertion:

• Insertional tendinopathy: Degeneration of tendon fibers at the bone attachment
• Calcific tendinosis: Calcium deposits within the tendon substance
• Repetitive loading: Chronic stress from activities like running or jumping
• Tendon shortening: Reduced flexibility increasing insertion site stress
• Age-related degeneration: Natural wear and tear over time

Biomechanical Contributing Factors

Foot Structure Abnormalities

• Flat feet (pes planus): Reduced arch height increases plantar fascia tension
• High arches (pes cavus): Abnormal weight distribution and increased heel pressure
• Overpronation: Excessive inward rolling of the foot during walking
• Supination: Inadequate inward rolling leading to reduced shock absorption
• Leg length discrepancy: Unequal leg lengths causing compensatory stress
• Ankle inflexibility: Limited dorsiflexion increasing heel cord tension

Gait and Movement Patterns

When to See a Doctor

While mild heel discomfort may resolve with conservative self-care measures, certain symptoms and situations warrant professional medical evaluation to ensure proper diagnosis and prevent complications.

Seek Immediate Medical Attention If:

• Sudden, severe heel pain following trauma or injury
• Inability to bear weight on the affected foot
• Severe swelling, redness, or warmth around the heel
• Signs of infection: fever, red streaking, pus, or severe warmth
• Numbness, tingling, or loss of sensation in the foot
• Severe pain that doesn't improve with rest and over-the-counter pain medication
• Visible deformity or significant change in foot shape
• Suspected fracture or complete tendon rupture

Schedule an Appointment If:

• Persistent foot or toe pain lasting more than 2-3 weeks
• Chronic ankle pain that interferes with daily activities
• Morning heel pain that doesn't improve after several weeks of self-care
• Progressive leg pain due to altered walking patterns
• Foot or toe swelling that persists or worsens
• Pain that significantly limits work, exercise, or daily activities
• Symptoms that worsen despite conservative treatment measures
• Recurrent episodes of heel pain

Specific Symptom-Based Guidelines

Pain Characteristics Requiring Evaluation

• Morning stiffness: Severe first-step pain lasting >30 minutes
• Night pain: Heel pain that awakens you from sleep
• Progressive pain: Symptoms that worsen over time
• Constant pain: Pain present even at rest
• Bilateral symptoms: Both feet affected simultaneously
• Radiating pain: Pain extending up the leg or into the toes

Functional Limitations
