Heel Pain: General Considerations
Heel pain is a common orthopedic complaint.
Establishing the correct diagnosis may be challenging due to:
close proximity of pain-generating structures,
complex regional anatomy of the heel.
Accurate diagnosis requires:
detailed medical history,
careful physical examination.
Appropriate treatment depends on:
correct identification of the underlying pathology.
Etiology of Heel Pain
Etiology is heterogeneous.
Diagnostic evaluation should consider:
duration of pain,
radiation,
time of maximal pain intensity,
relationship to walking or activity.
Localization of Heel Pain
Localization of pain is the most important diagnostic step.
Classification based on pain location:
facilitates diagnostic accuracy,
guides treatment selection.

Plantar fasciitis
Plantar fascia rupture
Calcaneal stress fracture

Plantar Fasciitis: Overview
Plantar fasciitis is:
the most common cause of plantar heel pain.
Most frequently affects individuals aged 40–60 years.
Occurs approximately twice as often in women.
Common in active individuals, particularly runners.
Reported prevalence ranges between 5% and 18%.
Anatomy of the Plantar Fascia
Origin:
medial tubercle of the calcaneus.
Insertion:
proximal phalangeal bases via five digital bands.
Components:
central component (most important),
medial plantar fascia,
lateral plantar fascia.
Functional Anatomy
The central component:
prevents collapse of the medial longitudinal arch.
Functions as a tension-bearing structure.
Comparable biomechanically to:
a rope or cable system.
Windlass Mechanism
Describes the dynamic role of the plantar fascia during gait.
During push-off:
dorsiflexion of the toes tensions the plantar fascia.
This shortens the distance between:
calcaneus and metatarsal heads.
Results in:
passive elevation of the medial longitudinal arch,
more efficient gait mechanics.
Pathophysiology of Plantar Fasciitis
Repetitive loading and overuse:
increase tensile stress at the calcaneal origin.
Leads to:
microtears,
inflammatory response,
chronic degenerative changes.
High stress concentration occurs at:
the calcaneal origin of the plantar fascia.
Risk Factors for Plantar Fasciitis
Intrinsic Factors
Obesity
Pes planus
Pes cavus
Achilles tendon contracture
Gastrocnemius tightness
Extrinsic Factors
Inappropriate footwear
Prolonged standing
Walking on hard surfaces
Barefoot walking
Occupations requiring heavy load-bearing
Clinical Presentation
Typical Symptoms
Pain is the dominant complaint.
Morning pain:
severe heel pain with the first steps after waking,
pain decreases after a few steps.
Recurrent pain:
occurs after prolonged sitting,
returns with standing or walking.
Pain Characteristics
Pain character is crucial for diagnosis.
Night pain is not typical.
Pain during activity:
usually does not worsen in early disease.
Worsening activity-related pain suggests:
progression to another pathology.
Physical Examination
Key Findings
Point tenderness at:
medial plantar heel,
medial calcaneal tubercle.
Windlass test:
passive dorsiflexion of the first MTP joint,
reproduces pain at the plantar fascia origin.
Increased plantar fascia tension may be palpated.
Additional Examination Components
Silfverskiöld test:
evaluates gastrocnemius tightness.
Neurological examination:
essential due to proximity of pain generators.
Baxter neuropathy:
pain near the proximal origin of abductor hallucis.
Lateral plantar nerve distribution:
neuropathic pain along the lateral plantar border.
Differential Neurologic Conditions
Baxter nerve entrapment
Tarsal tunnel syndrome
Particularly relevant in:
chronic cases,
patients unresponsive to prior surgical treatment.
Diagnostic Considerations
Diagnosis is primarily clinical.
Imaging is not required to confirm plantar fasciitis.
Radiographs are useful to:
exclude alternative diagnoses
tumors,
cysts,
osteomyelitis,
alignment abnormalities,
arthrosis.
Imaging in Plantar Fasciitis
Plain Radiographs
Calcaneal spur:
not specific to plantar fasciitis,
does not cause pain,
often incidental or secondary.
Advanced Imaging
Indicated in:
chronic,
refractory,
atypical heel pain.
Used to exclude:
plantar fascia rupture,
calcaneal stress fracture,
space-occupying lesions.
MRI Findings
Normal appearance.
Plantar fascia thickening.
Increased signal intensity (edema).
Presence or absence of calcaneal spur.
Treatment Overview
Initial treatment is always non-surgical.
Conservative treatments demonstrate:
approximately 90% success rate.
A stepwise, combined approach is commonly used.
Nonoperative Treatment
First-Line Measures
Patient education
Plantar fascia–specific stretching
Taping
Shoe modification
Prefabricated insoles or heel cups
NSAIDs
Second-Line Measures
Injection therapies (PRP or corticosteroid)
Joint and soft-tissue mobilization
Night splints
Custom-made orthoses
Extracorporeal shock wave therapy (ESWT)
Third-Line Measures
Surgical treatment
Considered after:
at least 6 months of adequate conservative management.
First-Line Nonoperative Treatment: Core Concepts
Patient education:
critical for long-term prognosis.
Plantar fascia–specific stretching:
cornerstone of treatment.
Taping:
provides short-term pain relief,
improves function.
Obesity:
dietary counseling may be beneficial.
Chronic disease course:
requires patience.
Plantar Fascia–Specific Stretching
All toes are dorsiflexed until:
tension is felt in the plantar fascia.
Provides:
short- and long-term pain reduction,
functional improvement.
Combined gastrocnemius–soleus stretching:
further enhances outcomes.
Footwear Modification and Orthoses
Avoid barefoot walking.
Rocker-bottom shoes:
facilitate push-off,
reduce plantar fascia tension.
Prefabricated or custom orthoses.
Heel cups.
Night splints:
should be part of combination therapy,
not used as sole treatment.
Injection Therapies
Corticosteroid Injections
Risk of plantar fascia rupture.
Risk of heel fat pad atrophy.
Provide:
shorter-term pain relief.
Platelet-Rich Plasma (PRP)
No reported rupture risk.
No fat pad atrophy.
Provides:
longer-lasting pain relief.
Comparative Evidence
10 comparative studies (517 patients):
PRP superior to steroids at 3 months.
No significant difference at 6–12 months.
Evidence limited by:
small number of high-quality trials.
When applied with correct technique:
corticosteroids demonstrate comparable short-term efficacy.
Extracorporeal Shock Wave Therapy (ESWT)
Introduced in the 2000s as an alternative to surgery.
Demonstrated efficacy.
In 2021:
highest level of evidence among second-line treatments.
Benefits include:
minimal side effects,
short-, mid-, and long-term effectiveness.
May be applied:
prior to injection therapies.
Surgical Treatment
Reserved for:
resistant cases,
failure of ≥6 months of conservative treatment.
Conservative management remains the primary approach in:
acute cases,
symptom duration <9 months.
Surgical Techniques
Proximal Plantar Fasciotomy
Performed at:
calcaneal origin.
Partial (medial 1/3–2/3) or complete release.
Techniques include:
open,
minimal incision,
percutaneous,
endoscopic.
Biomechanical Considerations
Loss of windlass mechanism.
Altered gait biomechanics.
Potential:
lateral column destabilization,
calcaneocuboid joint dysfunction.
Theoretical risk of flatfoot:
minimal in clinical practice,
excessive release should be avoided.
Endoscopic Plantar Fasciotomy
Widely accepted technique.
Comparable functional outcomes to open surgery.
Associated with:
fewer complications.
Medial Plantar Fasciotomy and Nerve Considerations
Involves:
release of the first branch of the lateral plantar nerve,
release of proximal fascia of abductor hallucis,
release of medial fascia of quadratus plantae.
Rationale:
Baxter neuropathy may coexist in ~50% of cases.
Considered in:
chronic,
atypical plantar fasciitis,
night pain,
activity-related pain.
Gastrocnemius Recession
Proximal medial gastrocnemius release.
Performed via:
mini-incision at the popliteal fossa.
May be performed under:
local anesthesia with sedation.
Reported outcomes:
high success in resistant plantar fasciitis.
No complications typically associated with:
plantar fasciotomy.
Pain localization is critical.
Silfverskiöld test:
should be performed in all cases.
Key Take-Home Messages
Heel pain requires precise localization.
Plantar fascia–specific stretching is foundational.
Heel cups and NSAIDs alone do not resolve plantar fasciitis.
Neurologic causes must always be excluded.
Combined and stepwise treatment yields optimal outcomes.
