plantar fasciitis

Etiology
- biomechanical disorders
- cavus foot
- planovalgus foot
- tight gastrocnemius-Achilles complex
- obesity especially a problem for people who stand for long periods of time
- improper footwear
- heel fat pad atrophy in individuals > 50 years of age
- overtraining: repetitive impact of heel strike[3]
- plantar spurs
- rheumatoid disease[10]
Epidemiology
Pathology
- stretching of plantar fascia at its site of calcaneal attachment (medial tuberosity)[2]
- during periods of rest, the plantar fascia shortens, resulting in a sudden stretch with the first step manifested as pain that usually diminishes with further steps[3]
- an associated factor is ankle equinus, reduction in dorsiflexion of ankle
- decreased ankle dorsiflexion causes increased stress on the plantar fascia during walking[3]
- inflammation, weakening & tearing of fibers[3]
- heel spur may occur as secondary process
Clinical manifestations
- inferior heal pain
- gradual onset
- burning or aching sensation
- activities exacerbating plantar fasciitis
- climbing hills or stairs
- standing on toes
- nocturnal cramps in the toe plantar flexors
- the foot feels weak
- pain with the 1st step*
- point tenderness over the origin of the plantar fascia at the medial process of the calcaneal tubercle
- passive toe dorsiflexion reproduces the pain*
- absence of other signs of inflammation (swelling, erythema, heat)
* Not likely a feature of other disorders in differential diagnosis
Radiology
- plain radiographs of foot & calcaneus:
- indications:
- symptoms developed acutely (calcaneus fracture suspected)
- clinical manifestations are atypical
- the patient is still growing
- heel spur may be present
- weight-bearing films not helpful
- indications:
- bone scan can help distinguish plantar fasciitis from calcaneal stress fracture
- ultrasound may be useful[17]
Differential diagnosis
- stress fracture of calcaneus
- acute in onset
- tenderness on medial & lateral aspect of heel
- generally visible on plain radiography
- no improvement withh ambulation
- tarsal tunnel syndrome
- burning pain extending into plantar aspect of toes
- may have positive Tinel's sign at tarsal tunnel
- Sever's disease
- neoplasm
- pain often worse or unchanged during rest
- unlikely to improve with treatment of fasciitis
- arthritis
- gout, rheumatoid arthritis, ankylosing spondylitis, Reiter's syndrome
- joint & bursa swelling is common
- arterial insufficiency
- heel pad syndrome
- Achilles tendonitis (posterior tibial tendonitis)
- symptoms worsen with prolonged ambulation
- tears of the plantar fascia
- may be visualized by ultrasonography or magnetic resonance imaging
- far less common than plantar fasciitis[3]
Management
- ice for 20 minutes several times/day especially after weight-bearing activities
- non-steroidal anti-inflammatory drugs (NSAIDs) for 2-3 weeks
- relative rest
- stretching exercises for plantar fascia & Achilles tendon
- physical therapy
- heel pad or wedge[3]
- arch support for pes planus [s9]
- taping
- orthotics of limited benefit[6]
- glucocortiocoid injection
- dexamethasone 4 mg[11]
- benefit at 4 weeks, but not at 8-12 weeks (ultrasound-guided)[11] NNT = 3
- potential for fat pad atrophy & rupture of plantar fascia
- night splints to maintain foot in a neutral or less plantar flexed position
- avoid walking barefoot or in slippers[10]
- surgery
- failure of 6 months of conservative management
- disability in activities of daily living
- exacerbating activities are considered very important to the patient
- extracorporeal shock wave therapy[4][5][14]
- prognosis: 80% resolve spontaneously within 1 year[10]
