Retrocalcaneal Bursitis
Lower LimbOverview
Retrocalcaneal bursitis is inflammation of the bursa situated between the Achilles tendon and the calcaneus, commonly caused by repetitive friction, tight footwear, or Haglund's deformity. This condition presents with posterior heel pain, swelling, and functional limitation during walking and running. Early recognition and management are essential to prevent chronic inflammation and secondary tendinopathy.
Pathophysiology
The retrocalcaneal bursa acts as a shock-absorbing structure to reduce friction between the Achilles tendon and the calcaneal prominence. Repetitive microtrauma, excessive pronation, tight calf muscles, or direct pressure from footwear causes bursal inflammation and fluid accumulation. This leads to swelling within the constrained space between the tendon and bone, causing pain with dorsiflexion and pressure. Chronic irritation can result in bursal fibrosis, calcification, and secondary Achilles tendinopathy.
Patient Education
Retrocalcaneal bursitis responds well to activity modification, calf stretching, and graduated return to activity; early intervention prevents progression to chronic tendon involvement and functional disability.
Typical Presentation
Site
Posterior heel, deep to the Achilles tendon insertion, proximal to the calcaneal prominence
Quality
Dull, aching pain with sharp exacerbations; may feel like a pinching sensation
Intensity
Mild to moderate (3-6/10), worse with activity, variable at rest
Aggravating
Dorsiflexion and plantarflexion against resistance, prolonged walking or running, tight posterior heel footwear, going upstairs, repetitive impact activities
Relieving
Rest, ice application, anti-inflammatory medication, heel lifts, soft footwear, stretching of calf muscles
Associated
Posterior heel swelling, localized warmth, stiffness after rest, difficulty with dorsiflexion, possible crepitus, Haglund's deformity, pes planus or cavus, calf muscle tightness
Orthopaedic Tests
Retrocalcaneal Bursa Palpation
Procedure
Patient supine or prone with ankle in slight plantarflexion. Palpate the soft tissue space between the Achilles tendon and calcaneus (anterior to the tendon insertion). Apply gentle pressure and note tenderness or fullness.
Positive Finding
Localized tenderness, swelling, or palpable thickening in the retrocalcaneal space
Sensitivity / Specificity
Unknown / Unknown
Interpretation
Confirms local inflammation of the retrocalcaneal bursa; however, palpation alone cannot definitively differentiate from Achilles tendinopathy or insertional pain
Silfverskiöld Test (Modified for Retrocalcaneal Bursa)
Procedure
Patient supine. Flex the knee to 90° and then dorsiflex the ankle. Repeat with the knee extended. Note if dorsiflexion range improves with knee flexion and whether pain is reproduced in the retrocalcaneal region.
Positive Finding
Pain localized to the retrocalcaneal region with the knee extended that improves with knee flexion; may indicate gastrocnemius tightness contributing to bursal irritation
Sensitivity / Specificity
Unknown / Unknown
Interpretation
Suggests gastrocnemius-soleus complex tightness as a contributing factor; helps differentiate from other heel pain sources
Achilles Tendon Squeeze Test (Midportion vs. Insertion)
Procedure
Patient prone. Squeeze the Achilles tendon at mid-belly (5 cm above insertion) and then at the insertion point. Note location of pain reproduction.
Positive Finding
Pain specifically at or immediately above the calcaneal insertion rather than at the mid-belly; swelling or tenderness anterior to the tendon insertion
Sensitivity / Specificity
Unknown / Unknown
Interpretation
Helps localize pathology to the insertional/retrocalcaneal region rather than mid-tendon; supports diagnosis of retrocalcaneal bursitis when insertion tenderness predominates
Dorsiflexion-Eversion Test (Retrocalcaneal Bursa Compression)
Procedure
Patient seated or supine. Actively dorsiflex and evert the foot, or passively position the ankle in dorsiflexion and eversion. Note pain reproduction in the retrocalcaneal region.
Positive Finding
Increased pain or pressure sensation in the retrocalcaneal space with dorsiflexion and eversion; compression of inflamed bursa
Sensitivity / Specificity
Unknown / Unknown
Interpretation
Dorsiflexion reduces plantarflexion tension on the Achilles and compresses the retrocalcaneal bursa; reproducing anterior heel pain suggests bursal irritation
Thompson Test (Plantarflexion Integrity Check)
Procedure
Patient prone with knees bent to 90°. Squeeze the calf muscle and observe for passive plantarflexion of the ankle. Perform bilaterally for comparison.
Positive Finding
Positive: absence of plantarflexion (indicates Achilles rupture); in retrocalcaneal bursitis, the test is typically negative but may produce pain at the insertion
Sensitivity / Specificity
95–98% (for rupture detection) / 99% (for rupture detection)
Matles, 1957, American Journal of Surgery; Hegedus et al., 2012, British Journal of Sports Medicine
Interpretation
Primarily rules out Achilles tendon rupture; pain without loss of function suggests intact tendon with bursal or insertional inflammation
Single-Leg Heel Raise Test (Plantarflexion Load Test)
Procedure
Patient standing. Perform a single-leg heel raise on the affected side, holding for up to 10 repetitions. Note pain location and ability to perform the movement.
Positive Finding
Inability to complete heel raises or sharp pain in the retrocalcaneal region during the plantarflexion movement; pain worsens with increased load
Sensitivity / Specificity
Unknown / Unknown
Interpretation
Functional test; reproduces symptoms during plantarflexion-dominant activity; helps assess severity and functional limitation; pain with plantarflexion loading supports retrocalcaneal pathology
⚠ Red Flags
- •Signs of acute infection: fever, severe localized warmth, systemic illness, immunocompromised state
- •Sudden severe pain with audible pop suggesting Achilles tendon rupture
- •Severe neurological symptoms: nerve compression causing distal sensory or motor changes
- •Significant swelling with calf pain suggesting deep vein thrombosis
- •History of malignancy with localized swelling
- •Signs of systemic arthropathy (rheumatoid arthritis, seronegative spondyloarthropathy) with polyarticular involvement
⚡ Yellow Flags
- •Psychologically-based pain amplification or catastrophizing about heel pain
- •High fear-avoidance beliefs limiting activity and rehabilitation engagement
- •Perfectionist or elite athlete mentality avoiding activity modification
- •Poor compliance with conservative measures or unrealistic expectations for rapid recovery
- •Secondary gain or compensation/litigation involvement
- •Depressive symptoms or anxiety exacerbating pain perception
- •Occupational factors with no activity modification: standing all day, repeated climbing
Osteopathic Techniques
Region
Calf muscles (gastrocnemius and soleus)
Technique
Soft Tissue
Rationale
Direct soft tissue release addresses muscle tension and trigger points that perpetuate bursal irritation through increased compression; reduces tension on the Achilles tendon insertion
Region
Posterior compartment lower leg
Technique
MET
Rationale
Muscle energy techniques restore normal dorsiflexion range and calf flexibility; reduces compressive forces on the retrocalcaneal bursa during functional activities
Region
Subtalar and ankle joints
Technique
Articulation
Rationale
Gentle ankle mobilization restores normal arthrokinematics, reduces compensatory stress on the heel, and normalizes Achilles tendon mechanics
Region
Plantar fascia and intrinsic foot muscles
Technique
Soft Tissue
Rationale
Releasing plantar fascia tension addresses foot pronation patterns and reduces abnormal stress transmission to the retrocalcaneal bursa
Region
Lumbar spine and thoracolumbar fascia
Technique
Articulation
Rationale
Addressing proximal spinal restrictions improves gait mechanics and reduces compensatory overpronation that perpetuates heel bursitis
Region
Retrocalcaneal bursa and surrounding tissue
