Treatment of Plantar Fasciitis
Begin with conservative therapy combining plantar fascia-specific stretching exercises, appropriate footwear, and heel cushions for 6 weeks, escalating to physical therapy, custom orthotics, and night splinting if symptoms persist. 1
Initial Conservative Management (First 6 Weeks)
Patient-Directed Measures
- Initiate regular calf-muscle and plantar fascia stretching exercises performed daily, as this represents the cornerstone of treatment 1, 2
- Apply ice massage to the affected area for pain control 1, 3
- Use over-the-counter heel cushions and arch supports to reduce mechanical stress 1
- Avoid walking barefoot or wearing flat shoes and slippers with thin soles, both indoors and outdoors 1, 2
- Modify activities to reduce prolonged standing and high-impact loading 3, 4
- Pursue weight loss if obesity is a contributing factor 1
Pharmacologic Therapy
- Consider NSAIDs for pain relief, though evidence shows only modest benefit with a trend toward improved outcomes between 2-6 months when combined with conservative measures 5
- NSAIDs provide symptomatic relief but are not curative; their use should be time-limited 5
Mechanical Interventions
- Apply padding and strapping of the foot to offload the plantar fascia 1
- Ensure proper footwear that accommodates foot shape and provides adequate support 2
Escalation if No Improvement After 6 Weeks
Refer to a podiatric foot and ankle surgeon or appropriate specialist for advanced conservative management 1
Physician-Prescribed Treatments
- Prescribe custom orthotic devices for biomechanical correction, which show limited but consistent evidence of benefit 1, 6
- Implement night splinting to maintain ankle dorsiflexion during sleep 1, 3
- Consider corticosteroid injections for short-term pain relief, though effects are transient and carry risks of fat pad atrophy and plantar fascia rupture 1, 4, 6
- Initiate formal physical therapy with supervised exercise programs targeting the foot and ankle over 8-12 weeks 2
- Use casting or fixed-ankle walker-type devices for immobilization in refractory cases 1
Management of Chronic Recalcitrant Cases (≥6 Months)
Advanced Diagnostic Evaluation
- Order ultrasonography as a reasonable, cost-effective diagnostic tool for patients with persistent pain beyond 3 months 2
- Consider MRI to characterize the plantar fascia and rule out other pathology in unclear cases 2
Definitive Treatment Options
- Extracorporeal shock wave therapy (ESWT) represents an evidence-based option for chronic plantar fasciitis unresponsive to conservative measures 3, 4
- Surgical plantar fasciotomy is reserved for the small percentage of patients (approximately 10%) who fail all conservative treatments after 6+ months 1, 3
Critical Clinical Pearls
The natural history shows 90% of patients improve with conservative treatment alone, making aggressive early intervention unnecessary 3, 7
Common Pitfalls to Avoid
- Do not inject corticosteroids directly into the Achilles tendon insertion, as this increases rupture risk 1
- Avoid premature surgical intervention before exhausting 6 months of appropriate conservative therapy 3
- Do not rely solely on NSAIDs without mechanical interventions, as the evidence for NSAIDs alone is weak 5
- Recognize that plantar fasciitis is largely a self-limiting degenerative condition, and overly aggressive treatment may cause more harm than benefit 3, 7
Treatment Algorithm Timeline
- Weeks 0-6: Patient-directed conservative measures with NSAIDs as needed 1
- Weeks 6-12: Add physician-prescribed interventions (orthotics, night splints, consider corticosteroid injection) 1
- Months 3-6: Continue conservative measures, consider ESWT for persistent symptoms 3, 4
- Beyond 6 months: Surgical consultation for fasciotomy only if all conservative measures have failed 1, 3
