Heel Fat Pad Syndrome

Lower Limb

Overview

Heel fat pad syndrome is a condition characterized by inflammation, atrophy, or displacement of the plantar fat pad beneath the calcaneus, resulting in localized heel pain and reduced shock absorption. This condition commonly affects middle-aged and older individuals, athletes with high-impact activities, and those with rapid weight gain. Pain is typically worse with weight-bearing activities and improves with rest and appropriate offloading.

Pathophysiology

The heel fat pad is a specialized cushioning structure composed of fibro-fatty tissue that provides shock absorption and protection to the plantar surface of the calcaneus during weight-bearing. Repetitive trauma, chronic overuse, rapid weight gain, aging, or loss of tissue hydration can lead to inflammation, atrophy, or anterolateral displacement of this fat pad. When compromised, the fat pad loses its ability to distribute pressure effectively, resulting in concentrated stress on the plantar fascia, calcaneal tuberosity, and surrounding soft tissues. This mechanism distinguishes heel fat pad syndrome from plantar fasciitis, though the two conditions frequently coexist.

Patient Education

Understanding that your heel pain may relate to loss of natural cushioning in your heel is important; maintaining healthy body weight, avoiding prolonged standing on hard surfaces, and using appropriate footwear with adequate heel padding can significantly reduce symptoms and prevent progression.

Typical Presentation

Site

Deep plantar surface of the heel, typically over the central or medial calcaneal tuberosity; may extend toward the medial or lateral aspects of the heel

Quality

Deep aching, sharp or burning pain; described as bruised or tender feeling in the heel; may feel like 'stepping on a stone'

Intensity

Mild to moderate (4-7/10), often worse in the morning with first steps or after prolonged standing; may increase throughout the day with weight-bearing activity

Aggravating

Prolonged standing or walking, high-impact activities (running, jumping), barefoot walking, hard floor surfaces, rapid weight gain, shoes with inadequate heel cushioning, obesity or increased body mass

Relieving

Rest and elevation, offloading pressure with cushioned orthotics or heel pads, soft supportive footwear, ice application, gentle stretching of calf and plantar fascia, weight loss

Associated

Morning stiffness in the heel, pain worse with first steps after rest, generalized foot fatigue, possible ankle stiffness, reduced pain with activity as tissues warm up, symptoms may worsen in the afternoon, possible tingling or radiating pain to the arch

Orthopaedic Tests

Test descriptions are written with AI assistance from standard clinical texts. Where a test lists Sources, its description has been checked against them; those sources are independent and do not endorse OsteoKit. Accuracy figures and grades (A–D) appear only when checked against the published study; tests without one are marked “No accuracy study”.

Further reading: full test procedures are described in standard clinical examination texts, e.g. Magee & Manske, Orthopedic Physical Assessment (7th ed.), and Cook & Hegedus, Orthopedic Physical Examination Tests: An Evidence-Based Approach (2nd ed.).

No accuracy study

Heel Fat Pad Palpation

Procedure

Patient prone or supine. Palpate the centre of the heel pad, then the medial calcaneal tubercle where the plantar fascia attaches, and compare.

Positive Finding

Tenderness in the centre of the heel, under the weight-bearing part of the calcaneus, rather than at the inner heel.

Interpretation

Central heel tenderness fits fat pad syndrome; tenderness at the medial tubercle fits plantar fasciitis. A thin or soft heel pad (the bone is easily felt) supports fat pad atrophy.

Sources

No accuracy study

Calcaneal Squeeze Test

Procedure

Squeeze the heel from both sides with the palms of your hands.

Positive Finding

Pain in the heel with side-to-side compression.

Interpretation

Pain with a side-to-side squeeze raises concern for a calcaneal stress fracture, especially in runners or people with low bone density, and needs imaging. Fat pad pain is usually more with direct pressure on the underside of the heel.

Sources

No accuracy study

Windlass Test

Procedure

Patient standing with the toes over the edge of a step, or seated. Passively extend the big toe as far as it will go.

Positive Finding

Reproduction of pain at the inner heel or along the plantar fascia.

Reference: Erdemir et al., 2009, Archives of Physical Medicine and Rehabilitation

Interpretation

A positive test points to plantar fasciitis rather than the fat pad. In fat pad syndrome the windlass test is usually painless.

Sources

No accuracy study

Calcaneal Eversion Test

Procedure

Hold the heel and gently tilt it into eversion and then inversion, asking about heel pain.

Positive Finding

Reproduction of heel pain with the tilt.

Interpretation

Not a recognised test for fat pad syndrome. Pain may come from the subtalar joint or the medial heel structures. Use palpation and the history (pain on hard surfaces or barefoot) instead.

Single Limb Stance with Heel Raise

Procedure

Ask the patient to stand barefoot on a hard floor on the affected leg, then walk a few steps barefoot and in cushioned shoes.

Positive Finding

Heel pain on standing and walking barefoot on a hard surface, eased by cushioning.

Interpretation

Pain that depends on the surface and cushioning fits fat pad syndrome and guides treatment (heel cups, cushioned footwear).

No accuracy study

Heel Fat Pad Compression

Procedure

Press firmly with your thumb into the centre of the heel pad from below.

Positive Finding

Reproduction of the familiar central heel pain.

Interpretation

Supports fat pad irritation.

⚠ Red Flags

  • •Severe unilateral swelling, erythema, or skin changes suggesting infection or cellulitis
  • •History of trauma with severe pain disproportionate to clinical findings
  • •Systemic symptoms including fever, weight loss, or general malaise suggesting systemic disease
  • •Night pain unrelated to activity or progressive neurological symptoms
  • •Signs of compartment syndrome or significant soft tissue compromise
  • •Suspected calcaneal fracture following acute injury

⚡ Yellow Flags

  • •High levels of health anxiety or fear-avoidance behavior
  • •Catastrophizing about heel pain or prognosis
  • •Expectation of quick fixes without lifestyle modification
  • •Recent significant life stressors or emotional distress
  • •Secondary gains from illness (attention, avoiding work/activity)
  • •Belief that pain always signals serious pathology
  • •Low mood or depression affecting self-care behaviors

Osteopathic Techniques

Care aims to relieve symptoms: rest, ice, NSAIDs, cushioned supportive footwear, low-dye taping and avoiding high-impact activity. A cup-shaped silicone heel gives the most relief.

Technique

Soft tissue, foot and ankleNo trials found

Rationale

Soft tissue to the plantar fascia, foot muscles and the tissues around the heel and ankle ligaments.

How it's done & evidence

How it's done

Hands-on kneading, stroking and sustained pressure to the plantar fascia, the small muscles of the foot and the tissues around the heel and the ankle ligaments.

Evidence in Heel Fat Pad Syndrome

Sources

Region

Gastrocnemius-soleus (calf)

Technique

Muscle energy, calf (gastrocnemius and soleus)No trials found

Rationale

Calf muscle energy technique to ease gastrocnemius-soleus tightness that limits ankle dorsiflexion.

How it's done, cautions & evidence

How it's done

The calf is taken to its barrier by dorsiflexing the ankle. The patient pushes the foot gently down, at about 10–20% effort, against resistance for 5–10 seconds, relaxes for 3–5 seconds, and the new barrier is taken up.

Cautions

Not used with an acute fracture, a joint infection or a bone malignancy; take care with severe osteoporosis or after surgery that limits muscle contraction. Use the least force needed: too much can tear a muscle or pull off a tendon, especially in older patients.

Region

Subtalar joint and foot

Technique

Articulation, ankle and footNo trials found

Rationale

Ankle, subtalar and midfoot glides, mainly to restore dorsiflexion and foot mobility.

How it's done, cautions & evidence

How it's done

Passive, rhythmic, low-velocity glides of the ankle (talocrural), subtalar, midfoot and toe joints, within or up to the end of the available range, often aimed at restoring ankle dorsiflexion.

Cautions

Before mobilising an acute ankle injury, check for fracture with the Ottawa ankle rules (tenderness over either malleolus), and palpate the base of the 5th metatarsal, the navicular and the midfoot for a Lisfranc injury.

Evidence in Heel Fat Pad Syndrome

Searched 25 Oct 2026: no trials of subtalar or foot mobilisation in heel fat pad syndrome.

Region

Plantar foot tender points

Technique

Counterstrain, foot and ankle tender pointsNo trials found

Rationale

Gentle indirect technique: tender points in the foot and ankle are eased by passive positioning.

How it's done, cautions & evidence

How it's done

Find a tender point in the foot, ankle or calf. Passively move the foot and ankle into the position where the tenderness and tissue tension ease most, and hold it for about 90 seconds while monitoring the point. Return slowly to neutral and re-check.

Cautions

Do not use over an acute fracture, or in a patient who cannot give feedback.
