Heel pain is a common complaint encountered in clinical practice, affecting individuals across all age groups. Among the various diagnostic tools available, the Calcaneal Squeeze Test stands out as a simple yet valuable clinical maneuver. This test is particularly important in differentiating causes of heel pain and guiding subsequent management. Understanding the meaning, application, and interpretation of the Calcaneal Squeeze Test is crucial for clinicians, especially podiatrists, sports medicine practitioners, and allied health professionals.
What is the Calcaneal Squeeze Test?
The Calcaneal Squeeze Test, sometimes referred to as the “heel squeeze test,” is a hands-on clinical examination technique used primarily to assess for pathologies of the calcaneus (heel bone). The test involves applying a gentle but firm lateral compression to the calcaneus, typically at its medial and lateral aspects. The patient’s response to this maneuver—especially the presence, location, and character of pain—can provide valuable diagnostic clues.
Clinical Indications
The Calcaneal Squeeze Test is most commonly indicated in patients presenting with:
- Acute or chronic heel pain
- A history of trauma to the heel
- Suspected calcaneal stress fracture
- Pediatric patients with heel pain (e.g., Sever’s disease)
- Athletes and active individuals with overuse injuries
Technique
The test is performed with the patient either seated or lying supine, with the foot relaxed. The examiner uses their thumb and fingers to grasp the medial and lateral sides of the calcaneus, then applies a gentle squeezing force. The maneuver is usually performed bilaterally for comparison.
A positive test is indicated by the reproduction of the patient’s typical heel pain during compression, often localized to the calcaneal body.
Interpretation
Positive Result
A positive Calcaneal Squeeze Test—where squeezing the calcaneus elicits pain—suggests pathology within the calcaneal bone or its adjacent structures. The most common causes include:
- Calcaneal Stress Fracture: Microfractures within the calcaneus, often due to repetitive impact, are a leading cause of a positive test. This is especially prevalent among runners, military recruits, and athletes.
- Sever’s Disease (Calcaneal Apophysitis): In children and adolescents, a positive test is strongly associated with this condition, which is an inflammation of the growth plate in the calcaneus.
- Other Pathologies: Less commonly, bone tumors, infections (osteomyelitis), or severe contusions can yield a positive result.
Negative Result
A negative Calcaneal Squeeze Test (i.e., no pain on compression) may suggest that the cause of heel pain is extra-osseous, such as:
- Plantar fasciitis (pain is more prominent on the plantar aspect, not the calcaneal body)
- Achilles tendinopathy
- Bursitis
- Nerve entrapments
Clinical Relevance
Differential Diagnosis
The Calcaneal Squeeze Test is particularly valuable in distinguishing between bony and soft tissue causes of heel pain. For example, plantar fasciitis—the most common cause of heel pain—rarely produces a positive squeeze test, as the pathology is in the fascia rather than the bone.
Pediatric Considerations
In children, a positive test is highly suggestive of Sever’s disease. This is a self-limiting condition that occurs during periods of rapid growth, and the test helps to avoid unnecessary imaging or interventions.
Sports Medicine
For athletes, especially those with a history of increased training intensity or volume, a positive test raises suspicion for a stress fracture. Early diagnosis is essential to prevent progression and facilitate appropriate management.
Limitations
While the Calcaneal Squeeze Test is highly useful, it is not definitive. False positives can occur in cases of severe soft tissue injury adjacent to the calcaneus, and false negatives may occur in early or mild stress fractures. Imaging (X-ray, MRI, or ultrasound) may be required for confirmation.
The Calcaneal Squeeze Test remains a cornerstone of clinical assessment for heel pain. Its simplicity, speed, and non-invasiveness make it an essential tool for podiatrists and other clinicians. By helping to localize pain to the calcaneus, the test guides further investigation and management, improving outcomes for patients with heel pain. However, like any clinical test, it should be interpreted in the context of a thorough history and examination, and followed by appropriate imaging when necessary.
