01Approach to the Critical Patient/attcp54

Immediate priorities

›Plantar fasciitis is a clinical diagnosis reached only after dangerous causes of heel and foot pain are excluded

›Mechanical pattern expected: worst with the first steps after rest, eases after a few minutes of walking, returns with prolonged loading

›Confirm the patient can bear weight and mobilize safely before discharge

›No fever, no true rest or night pain, no progressive neurologic deficit, no systemic upset

›Neurovascular assessment of the foot in every heel pain presentation

›Dorsalis pedis and posterior tibial pulses, capillary refill, and foot temperature

›Light touch, pinprick, and 10 g monofilament sensation

›Ankle jerk and straight-leg raise when radicular features are present

›Screen every person with diabetes and foot pain for infection and Charcot neuroarthropathy

›Inspect for ulcer, portal of entry, erythema, warmth, swelling, and midfoot deformity

›Check capillary glucose and inflammatory markers if any of these are present

›A warm swollen foot without a wound in a neuropathic patient is Charcot until proven otherwise

›Recognize the acute history that signals plantar fascia rupture

›Sudden severe arch or midfoot pain during push-off, sprinting, or a misstep

›Rupture may follow a recent plantar corticosteroid injection

›Ecchymosis and a palpable gap along the medial longitudinal arch

Red flag mimics to exclude before diagnosing plantar fasciitis

›Foot compartment syndrome

›Context of crush injury, calcaneal fracture, forefoot trauma, or prolonged immobilization

›Pain out of proportion, pain on passive toe stretch, tense compartments, evolving sensory loss

›Emergency fasciotomy; a compartment pressure within 30 mmHg of the diastolic pressure is diagnostic

›Necrotizing soft tissue infection of the foot

›Systemic toxicity, crepitus, hemorrhagic bullae, rapidly advancing erythema, skin anesthesia

›Diabetes, peripheral arterial disease, and immunosuppression are the major risk factors

›Fluid resuscitation, broad-spectrum antibiotics, and emergency surgical debridement; do not wait for imaging

›Septic arthritis of the ankle or subtalar joint and calcaneal osteomyelitis

›Fever, joint effusion, erythema, refusal to bear weight, elevated C-reactive protein

›Aspirate the joint before antibiotics where feasible; never pass the needle through cellulitis

›A penetrating heel wound or diabetic foot ulcer raises osteomyelitis risk

›Calcaneal stress or insufficiency fracture

›Insidious heel pain with night and rest pain and a positive mediolateral calcaneal squeeze test

›Runners, military recruits, low bone density, chronic corticosteroid use, and diabetes

›Radiographs are often normal in the first 2 to 3 weeks; MRI confirms

›Acute limb ischemia and peripheral arterial disease

›A cold, pale, pulseless, painful foot demands immediate vascular assessment

›Exertional calf and foot pain relieved by rest suggests claudication

›Cauda equina syndrome and S1 radiculopathy

›Saddle anesthesia, urinary retention, or bilateral leg symptoms mandate emergency lumbosacral MRI

›Unilateral posterior leg pain with a reduced ankle jerk and positive straight-leg raise points to the S1 root

›Deep vein thrombosis

›Unilateral calf swelling and tenderness with thrombotic risk factors

›Apply the Wells deep vein thrombosis score and objective testing rather than empirical anticoagulation

›Inflammatory enthesitis of spondyloarthropathy

›Bilateral heel pain in a patient under 40 years, or heel pain with inflammatory back pain

›Psoriasis, uveitis, dactylitis, urethritis, or inflammatory bowel disease

›Morning stiffness lasting more than 30 minutes that improves with activity

Escalation and specialty involvement

›Emergency surgical review for suspected compartment syndrome, necrotizing infection, or septic joint

›Draw blood cultures, start broad-spectrum antibiotics, keep the patient nil by mouth, and mark the skin

›Do not elevate the limb above the heart when compartment syndrome is suspected

›Vascular surgery for a cold or pulseless foot, rest pain, or tissue loss

›Spinal surgery with urgent lumbosacral MRI for cauda equina features

›Diabetic foot multidisciplinary team for infection, ulceration, or suspected Charcot neuroarthropathy

›Offloading and non-weightbearing pending imaging

›Orthopedic or foot and ankle surgery for a complete plantar fascia rupture with arch collapse or a displaced calcaneal fracture

›Rheumatology for suspected spondyloarthropathy with peripheral enthesitis

02History/hx43

Pain characteristics and time course

›Plantar medial heel pain localized to the calcaneal origin of the plantar fascia

›Often described as sharp, bruise-like, or burning

›Pain radiating into the medial arch along the fascia is typical

›Pain confined to the posterior heel points to Achilles or retrocalcaneal pathology instead

›First-step pain after rest

›Worst with the first steps in the morning or after prolonged sitting

›Eases within 5 to 10 minutes of walking, then worsens again with prolonged standing or by the end of the day

›Onset and trajectory

›Gradual onset over weeks without a single injury in most patients

›A sudden painful pop with immediate arch pain suggests plantar fascia rupture

›Constant pain, unrelenting night pain, or pain unrelated to weightbearing suggests tumor, infection, or stress fracture

›Duration and prior course

›Symptom duration guides escalation, as most cases resolve within 12 months

›Previous episodes, previous treatments tried, and the response and duration of each

Aggravating and relieving factors

›Activities that reproduce the pain

›Barefoot walking on hard floors, stair climbing, running, jumping, and prolonged standing

›A recent increase in training load, mileage, hill work, or a change to firmer footwear

›Factors that relieve the pain

›Rest, supportive cushioned footwear, arch support, and activity modification

›Warmth and gentle stretching before the first steps

›Situational contributors

›A new job or activity involving prolonged weightbearing on hard surfaces

›Recent weight gain or pregnancy

›Worn-out or unsupportive shoes, or a switch to minimalist shoes

Risk factors, medications, and systemic features

›Mechanical and metabolic risk factors

03Physical Exam/exam44

Inspection and gait

›Gait pattern

›Antalgic gait with reduced stance time on the affected side

›Toe-walking or walking on the lateral border to offload the heel

›Standing alignment

›Pes planus, pes cavus, and hindfoot valgus or varus

›Windlass efficiency assessed by asking the patient to rise onto the toes

›Skin and soft tissue

›Callus pattern, plantar keratosis or wart, and any portal of entry or foreign body

›Medial arch swelling or ecchymosis suggesting rupture

›Diabetic ulcer, erythema, or midfoot deformity

›Regional swelling and erythema

›Ankle or subtalar effusion, warmth, and erythema suggesting septic or inflammatory arthritis

›Posterior heel prominence and swelling of Haglund deformity

Palpation and provocative tests

›Point of maximal tenderness

›Reproduced at the medial calcaneal tubercle at the plantar fascia origin

›Worsened by passive dorsiflexion of the toes and ankle, which places the fascia on stretch

›Windlass test

›Passive dorsiflexion of the first metatarsophalangeal joint with the ankle at 90 degrees reproduces heel pain

›More sensitive when performed with the patient standing

›Tests that redirect the diagnosis

›Mediolateral calcaneal squeeze reproduces pain in calcaneal stress fracture, not in typical plantar fasciitis

›Tinel sign posterior to the medial malleolus suggests tarsal tunnel syndrome

›Dorsiflexion-eversion of the ankle with the toes held dorsiflexed for 10 seconds reproduces tarsal tunnel paresthesia

›Palpation along the fascia

›A discrete non-tender nodule suggests plantar fibromatosis

›A palpable gap with a weak windlass suggests rupture

04Differential Diagnosis/ddx47

Local soft tissue and heel pad causes

›Plantar fasciitis and plantar fasciosis

›The most common cause of plantar heel pain, responsible for about 80% of presentations

›Degenerative rather than primarily inflammatory on histology

›Plantar fascia rupture

›Acute pop, arch ecchymosis, palpable defect, and a weak windlass

›May follow repeated corticosteroid injection

›Heel fat pad syndrome and fat pad atrophy

›Diffuse central heel tenderness, worse on hard surfaces, common in older and obese patients

›Plantar fibromatosis (Ledderhose disease)

›Firm nodule within the fascia, usually non-tender, and may be bilateral

›Posterior heel disorders

›Insertional Achilles tendinopathy, retrocalcaneal bursitis, and Haglund deformity produce posterior not plantar pain

›Foreign body granuloma, infected callus, or plantar wart

›Focal tenderness at a visible skin lesion or entry point

›Consider a radiopaque foreign body after a penetrating injury

Bone and stress-related causes

›Calcaneal stress fracture

›Insidious, activity-related, night and rest pain, with a positive squeeze test

›Athletes, military recruits, and patients with low bone density

›Calcaneal insufficiency fracture

›Older adults with osteoporosis, diabetes, or chronic corticosteroid use

›Subtalar or talonavicular osteoarthritis

›Stiffness and pain with hindfoot inversion and eversion

›Calcaneal osteomyelitis

›Diabetic foot, penetrating wound, fever, and elevated inflammatory markers

›Bone tumor

›Osteoid osteoma with night pain relieved by nonsteroidal anti-inflammatory drugs

05Laboratory Tests/lt39

Inflammatory and infectious workup

›Order only when clinical features warrant, not routinely

›Isolated mechanical first-step heel pain with a normal examination requires no laboratory testing

›Testing is driven by fever, systemic upset, an effused joint, or features of spondyloarthropathy

›Complete blood count

›Leukocytosis when septic arthritis or osteomyelitis is suspected

›C-reactive protein and erythrocyte sedimentation rate

›C-reactive protein reported in mg/l and the sedimentation rate in mm/hr

›Elevated in septic arthritis, osteomyelitis, and active spondyloarthropathy

›Normal values do not exclude spondyloarthropathy, and mild elevation is common with obesity alone

›Blood cultures

›Two sets before antibiotics if febrile or systemically unwell

›Joint aspiration

›Cell count, Gram stain, crystal microscopy, and culture when an adjacent joint is effused

›Do not aspirate through overlying cellulitis

›Serum urate

›Supportive only; it can be normal during an acute gout flare and is frequently elevated without disease

›HLA-B27

›Order through rheumatology follow-up, not the emergency department

›Present in about 6 to 8% of the healthy population, so a positive result is supportive not confirmatory

›Rheumatoid factor and anti-cyclic citrullinated peptide antibody

›Only when an inflammatory polyarthritis is present

Metabolic and systemic workup

›Glucose and glycated hemoglobin

›Capillary or fasting glucose reported in mmol/l

›Screen for diabetes in bilateral or refractory heel enthesopathy and before corticosteroid injection

›25-hydroxyvitamin D

›Reported in nmol/l; deficiency below 30 nmol/l is associated with plantar fasciitis

06Diagnostic Tests/dt62

Scoring Systems

›Patient-reported outcome measures used to grade severity and track response

›Foot Function Index and the Foot Health Status Questionnaire

›Foot and Ankle Ability Measure and the Manchester-Oxford Foot Questionnaire

›Visual analogue scale for first-step pain, recorded from 0 to 100 mm

›Plantar Fasciitis Pain and Disability Scale

›Region-specific measure combining pain and functional limitation

›Useful for tracking a single patient over time rather than for diagnosis

›Roles and Maudsley score

›Four-point patient-satisfaction outcome used in shockwave and injection trials

›Grades run from excellent to poor

›AOFAS Ankle-Hindfoot Scale

›Widely quoted but not formally validated; interpret trends rather than absolute values

›Decision rules for excluding other diagnoses

›Ottawa Ankle Rules to decide whether radiographs are needed when there is bony tenderness after trauma

›Wells score for deep vein thrombosis when calf swelling accompanies the foot pain

Radiographs

›Weightbearing lateral and axial calcaneal views

›Indicated only when an alternative bony diagnosis is suspected, not to confirm plantar fasciitis

›Not required for a typical first presentation with a classic history and examination

›Findings that are incidental

›An inferior calcaneal enthesophyte (heel spur) is seen in about 50% of patients and in 15 to 30% of asymptomatic adults

›The spur lies within the flexor digitorum brevis origin and is not the source of pain

›Findings that redirect management

›A sclerotic line or cortical break of the calcaneal tuberosity suggests stress fracture

›Fluffy periostitis or erosion at the enthesis suggests seronegative spondyloarthropathy

›A lytic lesion, cyst, or aggressive periosteal reaction suggests tumor or infection

›A radiopaque foreign body in the heel pad

›Heel pad assessment

›Reduced heel pad thickness and compressibility supports fat pad atrophy

Ultrasound

›Plantar fascia thickness at the calcaneal insertion

›A thickness greater than 4 mm supports the diagnosis

›The normal fascia measures less than 4 mm, and the asymptomatic contralateral fascia is typically 2.5 to 3 mm

›Endurance athletes and a recently injected heel can measure 4 to 5 mm without symptoms; compare with the other foot and correlate with the examination

›Children have a thinner fascia, so adult thresholds do not apply

›Additional grayscale and Doppler features

›Hypoechoic fusiform thickening with loss of the normal fibrillar pattern

›Perifascial fluid and hyperemia on power Doppler

›Focal discontinuity or a hypoechoic cleft indicates a partial or complete tear

›Practical role

›Bedside confirmation when the diagnosis is uncertain, and to exclude a tear before injection

›Real-time guidance for corticosteroid or platelet-rich plasma injection improves accuracy

›Avoids ionizing radiation and is well suited to pregnancy

MRI

›Primary indications

›Refractory pain beyond 6 to 12 months despite adequate conservative therapy

›Suspected plantar fascia rupture, calcaneal stress fracture, osteomyelitis, tumor, or nerve entrapment

›Characteristic findings

›Plantar fascia thickening greater than 4 mm with perifascial edema on fat-suppressed T2 or STIR sequences

›Reactive marrow edema at the calcaneal tuberosity

›A fluid-filled gap indicates a full-thickness rupture

›Findings that change the diagnosis

›A calcaneal fracture line with extensive marrow edema

›A bone or soft tissue mass, abscess, or sinus tract

›Denervation edema or atrophy of the abductor digiti minimi in Baxter neuropathy

›Limited role in plantar heel pain

›Poor soft tissue contrast means CT cannot assess the plantar fascia itself

›Reserve it for bony questions when MRI is unavailable or contraindicated

›Useful applications

›Characterizing a calcaneal stress or insufficiency fracture when MRI cannot be obtained

›Defining tarsal coalition, a calcaneal cyst, or an osteoid osteoma nidus

›Surgical planning for complex calcaneal deformity

›Cautions

›Delivers ionizing radiation and should be avoided in pregnancy unless essential

›A normal CT does not exclude an early stress fracture; MRI or a delayed radiograph is more sensitive

07Disposition/dispo26

Discharge and outpatient referral pathways

›Most patients are discharged from the emergency department

›Provide analgesia, a written stretching and footwear plan, and safety-net advice

›Supply crutches and a walking boot for severe pain or when a stress fracture or rupture is being excluded

›Routine onward referral

›Physiotherapy or podiatry within 2 to 4 weeks for a supervised program

›Primary care review at 6 to 8 weeks to assess response and consider corticosteroid injection or imaging

›Specialist referral

›Foot and ankle surgery when symptoms persist beyond 6 to 12 months despite adequate conservative therapy

›Rheumatology for features of spondyloarthropathy

›Sports medicine for athletes needing a graded return-to-running plan

›Work and activity guidance

›Temporary reduction of prolonged standing and high-impact activity, with cross-training to maintain fitness

›Most patients do not need time off work if standing can be limited and footwear optimized

Admission and urgent specialty referral criteria

›Immediate surgical or medical admission

›Suspected foot compartment syndrome

›Suspected necrotizing soft tissue infection

›Septic arthritis of the ankle or subtalar joint, or calcaneal osteomyelitis

›Acute limb ischemia

›Emergency neurosurgical or spinal referral

›Cauda equina features with saddle anesthesia, urinary retention, or bilateral leg symptoms

›Orthopedic referral, often same day

›Displaced calcaneal fracture

›Complete plantar fascia rupture with marked arch collapse or midfoot instability

›Consider short-stay observation or admission

›Pain preventing safe mobilization at home despite oral analgesia

›Diabetic foot infection or new Charcot neuroarthropathy requiring offloading and multidisciplinary input

08Treatment/t145

First-line conservative measures

›Set expectations at the first visit

›80 to 90% of patients improve within 12 months with conservative care

›Recovery is usually measured in months, and several measures are combined rather than used singly

›Relative rest and activity modification

›Reduce running, jumping, and prolonged standing to a pain-tolerable level

›Maintain fitness with cycling, swimming, or pool running

›Return to impact activity is graded once first-step pain settles

›Footwear

›A supportive shoe with a cushioned heel, arch support, and a slight heel-to-toe drop

›Avoid flat unsupportive shoes, worn-out shoes, and barefoot walking on hard floors

›A rocker-sole shoe reduces load on the fascia during push-off

›Ice and topical measures

›Roll the arch over a chilled bottle for 15 to 20 minutes after activity, up to 3 to 4 times daily

›Weight management

›Aim for a 5 to 10% weight reduction where the body mass index exceeds 25 to 30 kg/m2

›Interpret body mass index with caution in muscular athletes, and do not pursue active weight loss during pregnancy

Analgesia and anti-inflammatory pharmacotherapy

›Acetaminophen

›500 to 1000 mg orally every 6 hours as needed

›Maximum 3 g per day in older adults, low body weight, hepatic impairment, or chronic alcohol use, otherwise 4 g per day

›First-choice simple analgesic where a nonsteroidal drug is contraindicated

›Oral nonsteroidal anti-inflammatory drugs

›Ibuprofen 400 mg orally every 8 hours with food

›Maximum 1200 mg per day without medical supervision and 2400 mg per day when prescribed

›Limit to a 2 to 3 week course; evidence supports short-term pain relief, not disease modification

›Naproxen 500 mg orally twice daily

›Maximum 1000 mg per day

›Preferred where a longer dosing interval aids adherence

›Co-prescribe a proton pump inhibitor such as pantoprazole 40 mg orally once daily if age over 65 years or with gastrointestinal risk factors

›Avoid in chronic kidney disease stage 3 or worse, heart failure, active peptic ulcer disease, and the third trimester of pregnancy

›Topical nonsteroidal anti-inflammatory drug

›Diclofenac 1% gel, 2 to 4 g to the affected area four times daily

›Maximum 32 g per day at a single lower-limb site

›Preferred when systemic nonsteroidal exposure is undesirable, as systemic absorption is low

›Neuropathic agents

›Not indicated for plantar fasciitis, which is a mechanical enthesopathy

›Reserve for confirmed tarsal tunnel syndrome, Baxter neuropathy, or S1 radiculopathy, managed on their own pathways

Stretching, physiotherapy, and load management

›Plantar fascia-specific stretching

›Cross the affected leg over the other, pull the toes into dorsiflexion until a stretch is felt in the arch, hold 10 seconds, repeat 10 times

›Perform 3 times daily, including before the first steps out of bed

›Superior to calf stretching alone for short-term pain and function

›Gastrocnemius and soleus stretching

›Wall or step stretches with the knee straight and then bent, 3 sets of 30 seconds, 2 to 3 times daily

›High-load strength training

›Slow heel raises with a rolled towel under the toes to engage the windlass, performed every other day

›Progress load gradually over 8 to 12 weeks

›Adjuncts delivered by physiotherapy

›Manual therapy of the ankle and first metatarsophalangeal joint

›Low-Dye taping as a short-term and diagnostic trial of mechanical unloading

›Dry needling has low-quality evidence and is optional

›Referral

›Refer to physiotherapy or podiatry for supervised progression and adherence support

Orthoses, taping, and night splints

›Foot orthoses

›Prefabricated arch-supporting insoles are as effective as custom devices for most patients and cost less

›Reserve custom orthoses for a significant structural abnormality such as marked pes planus or a leg-length discrepancy

›Orthoses improve function and pain over weeks to months, not immediately

›Heel cups and pads

›Silicone heel cups help when there is a fat pad component or heel pad atrophy

›Low-Dye taping

›Provides short-term relief and predicts response to orthoses

›Night splints

›Hold the ankle at 5 degrees of dorsiflexion overnight for 1 to 3 months

›Most useful for pronounced morning pain and symptoms present for more than 6 months

›Reduce the dorsiflexion angle if calf tightness or neuropathy limits tolerance, and avoid forced dorsiflexion in diabetic neuropathy because of skin breakdown risk

›Adherence is the main limitation because of discomfort

Corticosteroid injection

›Indication

›Significant pain despite 6 to 8 weeks of supervised stretching and orthoses, or pain severe enough to prevent participation in rehabilitation

›Confirm there is no clinical or ultrasound evidence of a partial tear before injecting

›Agent and dose

›Triamcinolone acetonide 40 mg or methylprednisolone acetate 40 mg

›Mixed with 1 to 2 ml lidocaine 1% without epinephrine

›Keep total local anesthetic well below 4.5 mg/kg and not exceeding 300 mg of plain lidocaine

›Use a medial approach rather than a plantar approach to spare the heel fat pad and plantar skin

›Inject the deep aspect at the calcaneal origin, not into the substance of the fascia

›Frequency limit

›No more than 2 to 3 injections per heel, spaced at least 6 weeks apart

›Cumulative injections raise the risk of rupture and fat pad atrophy

›Benefit and its ceiling

›Provides pain relief for about 4 to 12 weeks, with no demonstrated benefit beyond 3 months

›Always paired with continued stretching, footwear change, and load management

›Complications to counsel and monitor

›Plantar fascia rupture in approximately 2 to 10%, plantar fat pad atrophy, and skin depigmentation

›A post-injection pain flare for 24 to 48 hours

›Infection is rare; stop and reassess for septic arthritis if pain and swelling escalate

›Transient hyperglycemia in diabetes, with a capillary glucose rise of about 3 to 5 mmol/l for 24 to 72 hours

›Expect a higher and longer rise with insulin resistance, intercurrent illness, or a high-dose depot preparation, and arrange closer monitoring and pre-emptive dose adjustment

›Monitoring after the procedure

›No titrated intravenous infusions are used in plantar fasciitis, so the only monitoring obligation is post-procedure

›Observe briefly for a vasovagal response, then review at 6 weeks to assess response and plan the next step

›A routine electrocardiogram is not required because no plantar fasciitis therapy causes an electrolyte shift

Refractory disease procedures and surgery

›Re-evaluate before escalating when 6 to 8 weeks of supervised therapy has not helped

›Re-take the history and re-examine for a missed stress fracture, nerve entrapment, or spondyloarthropathy

›Confirm that adherence, stretching technique, footwear change, and load reduction were actually implemented

›Obtain ultrasound or MRI to confirm the diagnosis and exclude a tear

›Only then escalate to injection, shockwave therapy, or surgical referral

›Extracorporeal shockwave therapy

›For chronic refractory plantar fasciitis present beyond 6 months

›Typically 3 weekly sessions; focused and radial devices are both used

›Avoid with coagulopathy, therapeutic anticoagulation, pregnancy, and over an open growth plate

›Platelet-rich plasma and needle procedures

›Autologous platelet-rich plasma injection may give better pain relief than corticosteroid at 3 to 12 months, though the evidence is heterogeneous

›Ultrasound-guided percutaneous needle fenestration of the fascia, with or without platelet-rich plasma

›Botulinum toxin type A

›OnabotulinumtoxinA 40 to 100 units injected into the plantar fascia or the medial and lateral gastrocnemius

›Units are not interchangeable between botulinum toxin products

›Investigational for this indication; verify the institutional protocol before use

›Surgery

›Partial plantar fasciotomy, open or endoscopic, for the fewer than 5% who fail 12 months of conservative care

›Release less than 40% of the fascia width to limit lateral column overload and longitudinal arch collapse

›Recovery takes 3 to 6 months

›Gastrocnemius recession where there is an isolated gastrocnemius contracture on the Silfverskiold test

›Baxter nerve decompression when first-branch lateral plantar nerve entrapment is confirmed

Plantar fascia rupture management

›Recognition

›Sudden arch pain during push-off or sprinting, or after a recent corticosteroid injection

›Arch ecchymosis, a palpable defect, swelling, and a weak windlass

›Investigation

›Ultrasound or MRI confirms discontinuity and grades a partial versus complete tear

›Management

›Non-weightbearing in a walking boot or short-leg cast for 2 to 3 weeks, then progressive weightbearing and rehabilitation

›Most tears heal by fibrosis without surgery

›Analgesia with acetaminophen and a short nonsteroidal course as dosed above

›Counseling

›Spontaneous rupture can relieve prior plantar fasciitis pain but risks arch collapse, lateral column pain, and midfoot instability

›No further corticosteroid injection into a ruptured or partially torn fascia

Therapies not supported or requiring modification

›Systemic corticosteroids

›Oral prednisolone is not recommended; one randomized trial used prednisolone 25 mg orally once daily for about 2 weeks with only short-term benefit and steroid-related risk

›Opioids

›Not indicated for a self-limited musculoskeletal condition

›If genuinely unavoidable for a defined severe flare, limit codeine 30 mg orally every 6 hours as needed, maximum 240 mg per day, for no more than 3 days, and document the plan

›Routine antibiotics

›No role unless infection is present; fasciitis here is a degenerative enthesopathy, not an infective process

›Prolonged immobilization and complete bed rest

›Cause deconditioning and stiffness; reserve casting for confirmed rupture or stress fracture

›Passive electrophysical agents

›Therapeutic ultrasound and low-level laser therapy have inconsistent evidence and are not first-line

›Corticosteroid iontophoresis gives only short-term benefit and is resource-intensive

›Injection practice cautions

›Do not inject both heels at one visit

›Do not use epinephrine-containing local anesthetic in the foot, an end-arterial field; use plain lidocaine

›Routine emergency interventions and how they apply here

›Intubation and procedural sedation are not required; local anesthetic alone suffices for injection

›Intravenous fluid loading, supplemental oxygen, and vasopressors have no role; infiltrated epinephrine or a peripheral vasoconstrictor risks forefoot ischemia

›Mechanical circulatory support, including the intra-aortic balloon pump, is irrelevant to this condition

›Do not start anticoagulation for presumed deep vein thrombosis without objective testing; therapeutic anticoagulation and antiplatelet therapy are relative contraindications to injection and shockwave therapy because of bleeding and plantar hematoma

›Fibrinolysis has no role; heel pain mistaken for an arterial event must not trigger thrombolysis

›Escalating analgesia must not be used to cover an undiagnosed foot, because nonsteroidal drugs can precipitate acute kidney injury and gastrointestinal bleeding and can mask an evolving compartment syndrome or septic arthritis

09Special Populations/sp50

Pregnancy

›Contributing factors

›Weight gain, fluid retention, and ligamentous laxity increase plantar fascia load

›Symptoms often begin in the third trimester and postpartum

›Preferred management

›Footwear, arch support, activity modification, calf and plantar fascia stretching, and ice

›Acetaminophen 500 to 1000 mg orally every 6 hours as needed, maximum 3 g per day in older adults, low body weight, hepatic impairment, or chronic alcohol use, otherwise 4 g per day, is the analgesic of choice

›Cautions

›Avoid oral nonsteroidal anti-inflammatory drugs, especially after 20 weeks and firmly in the third trimester, because of ductus arteriosus constriction and oligohydramnios

›Avoid extracorporeal shockwave therapy in pregnancy

›Limit corticosteroid injection to disabling pain unresponsive to conservative care, using ultrasound guidance

›Do not pursue active weight loss during pregnancy

›Imaging

›Ultrasound and non-contrast MRI are preferred; avoid CT and radiographs unless essential

Geriatric

›Distinguishing features

›Heel pad atrophy and calcaneal insufficiency fracture are more common and can coexist with fasciitis

›A lower baseline ankle dorsiflexion range is expected

›Analgesia adjustments

›Acetaminophen 500 to 1000 mg orally every 6 hours as needed, maximum 3 g per day in older adults, low body weight, hepatic impairment, or chronic alcohol use, otherwise 4 g per day

›Oral nonsteroidal drugs carry higher risks of acute kidney injury, gastrointestinal bleeding, and heart failure; if used, add pantoprazole 40 mg orally once daily and use the shortest course

›Prefer diclofenac 1% gel, 2 to 4 g four times daily, maximum 32 g per day at a single lower-limb site

›Procedure considerations

›Heel pad atrophy worsens after plantar corticosteroid injection, so favor the medial approach and limit repetition

›Review anticoagulant and antiplatelet therapy before injection or shockwave therapy

›Falls and function

›Night splints and bulky orthoses can increase trip risk; check gait aids and home hazards

Pediatrics

›Plantar fasciitis is uncommon before skeletal maturity

›Calcaneal apophysitis (Sever disease) is the usual cause of activity-related heel pain at ages 8 to 14

›Posterior-plantar heel pain, a positive squeeze test, a tight gastrocnemius, and a recent growth spurt or increase in sport

›Red flags in a child with heel pain

›Night pain, systemic symptoms, limp at rest, joint swelling, or a mass suggest infection, malignancy, or juvenile spondyloarthropathy

›Bilateral enthesitis raises enthesitis-related juvenile idiopathic arthritis

›Management of apophysitis and adolescent fasciitis

›Activity modification, calf and plantar fascia stretching, heel cushions, and ice

›Ibuprofen 10 mg/kg orally every 6 to 8 hours as needed, maximum 40 mg/kg per day and not exceeding 400 mg per dose, for short courses only

›Acetaminophen 15 mg/kg orally every 6 hours as needed, maximum 75 mg/kg per day and not exceeding 4 g per day

›Avoid in children

›Corticosteroid injection and extracorporeal shockwave therapy over an open calcaneal apophysis

›Applying adult ultrasound thickness thresholds, because the pediatric fascia is thinner

Diabetes, inflammatory arthropathy, and athletes

›Diabetes

›Examine for ulcer, infection, and Charcot neuroarthropathy before attributing foot pain to fasciitis

›Warn about transient hyperglycemia after corticosteroid injection and arrange glucose monitoring for 24 to 72 hours

›Avoid forced-dorsiflexion night splints where there is neuropathy because of skin breakdown risk

›Inflammatory arthropathy

›Bilateral heel enthesitis, inflammatory back pain, psoriasis, dactylitis, or uveitis warrants rheumatology referral

›Enthesitis-predominant disease responds poorly to local measures alone and may need systemic therapy

›Local corticosteroid injection into an actively inflamed enthesis carries a higher rupture risk

›Athletes and occupations with prolonged standing

›Correct training errors: rapid mileage increase, hill work, hard surfaces, and worn footwear

›Maintain fitness with non-impact cross-training and use a graded return-to-running progression

›Consider a temporary change of work footwear, anti-fatigue matting, and rotation of standing tasks

10Background/b39

Epidemiology

›Burden

›The most common cause of plantar heel pain, responsible for about 80% of such presentations

›Lifetime prevalence is about 10%

›Accounts for roughly 1 million ambulatory care visits per year in the United States

›Who is affected

›Peak age 40 to 60 years in the general population, and younger in running athletes

›Bilateral in about one third of patients

›A slight female predominance in non-athletes

›Risk factors with approximate effect

›Obesity, with an odds ratio of roughly 2 to 3

›Prolonged weightbearing occupations

›Reduced ankle dorsiflexion, with progressively higher risk as dorsiflexion falls

›Pes planus and pes cavus, and a rapid increase in running volume

›Natural history

›80 to 90% of patients resolve within 12 months with conservative care

›Fewer than 5% ultimately undergo surgery

Pathophysiology

›Structure and function

›The plantar aponeurosis runs from the medial calcaneal tubercle to the proximal phalanges and supports the medial longitudinal arch

›The windlass mechanism tightens the fascia and raises the arch as the toes dorsiflex during push-off

›Disease mechanism

›Repetitive tensile overload produces microtears at the calcaneal enthesis

›Histology shows collagen degeneration and angiofibroblastic hyperplasia with little inflammation, hence the term fasciosis

›A tight gastrocnemius-soleus complex increases forefoot load and fascial strain

›Associated findings

›The inferior calcaneal spur is a traction enthesophyte within the flexor digitorum brevis origin and is usually incidental

›Heel fat pad thinning contributes in older patients

11Patient Discharge Instructions/pdi32

Warning signs requiring reassessment

›Return immediately for

›Fever, spreading redness, or a hot swollen foot or ankle

›A cold, pale, or numb foot

›What plantar fasciitis is

›Irritation and small tears where the thick band of tissue along the sole attaches to the heel bone

›It is common, not dangerous, and usually settles over several months

›The heel spur sometimes seen on an x-ray is not the cause of the pain and does not need removal

›Daily stretching, the most important treatment

›Before your first steps each morning, cross the sore foot over the other knee, pull the toes back toward the shin until you feel a stretch in the arch, hold for 10 seconds, and repeat 10 times

›Do this 3 times a day, including before standing up after sitting

›Stretch your calf against a wall with the knee straight and then bent, holding 30 seconds each, 3 times a day

›Footwear and activity

›Wear supportive cushioned shoes with good arch support, indoors and outdoors, and avoid walking barefoot on hard floors

›Use an over-the-counter arch-support insole or a silicone heel cup in both shoes

›Roll the arch over a frozen water bottle for 15 to 20 minutes after activity

›Cut back on running, jumping, and long periods of standing for now, and keep fit with cycling or swimming

›Medication

›For pain, take acetaminophen 500 to 1000 mg every 6 hours, and no more than 3 g (six 500 mg tablets) in 24 hours unless your clinician has told you the 4 g limit is safe for you

›If your clinician agrees it is safe, ibuprofen 400 mg with food every 8 hours, and no more than 1200 mg in 24 hours without medical advice, may be used for 1 to 2 weeks

›Do not use ibuprofen or naproxen if you have kidney disease, heart failure, a stomach ulcer, or are more than 20 weeks pregnant
