Differential diagnosis

Plantar Fasciitis/Fasciopathy

Significant History/Physical symptoms

Plantar heel pain is a common problem in the foot, said to affect around 10% of adults during their lifetime (Babatunde et al, 2019) and there are a variety of mechanical factors that can contribute to the onset of pain around this area. Plantar fasciopathy (fasciitis, fasciosis) is likely the most common diagnosis, however the etiology of plantar heel pain is still not fully understood. Evidence suggests that it is associated with a high BMI, reduced ankle joint dorsiflexion and reduced strength in specific muscle groups, however, there is insufficient evidence that foot alignment is an important factor to consider (Sullivan et al, 2020).

It is crucial that the clinicians exclude red flags and serious pathology before settling on a diagnosis. Plantar fasciitis is usually diagnosed by clinical findings alone; if characteristic signs and symptoms are present the diagnosis is likely to be accurate. It is usually worse on initial weight bearing in the morning, better throughout the day and increasing in the evening, and often there is tenderness at the medial tubercle where it attaches to the calcaneum.

Fat Pad Atrophy

Significant History/Physical symptoms

Fat pad atrophy is where the layer of fat that lies under the heel bone, begins to waste away due to too much strain being placed on the pad. People who wear high heels for a period of many years have an increased risk of developing fat pad atrophy.

Pain is usually felt in the central heel as a dull deep ache that feels like a bruise. Direct pressure with thumb to plate centre often recreates pain. This is a non–radiating pain, medial calcaneal tuberosity and planter fascia NOT affected. Pain is aggravated by walking barefoot on hard surfaces.

It is more common in elderly / overweight females, in occupations involving standing on concrete floors for long periods, or in patients with diabetes mellitus.

  • Centralised or diffuse heel pain
  • Dorsiflexion of toe does not increase pain
  • Flattened, atrophied surface
  • Often elderly or obese patients

Less Common Differential Diagnoses not included in this pathway:

  • Tarsal Tunnel Syndrome
  • Nerve entrapment
  • Traumatic (fracture / heel bruise)
  • Bursitis
  • Infection
  • Tumour
  • Plantar calcaneal bursitis
  • Stress fracture of calcaneum
  • Calcaneal apophysitis
  • Skin lesion e.g. verrucae, corn

First line intervention

The first line intervention should focus on educating the patient about the condition, and prescribing therapies that can be self-administered by the patient.

Leaflets should be given to patients to reinforce verbal advice and links to NHS website resources where available.

Reasons that may require escalation to 2nd line intervention immediately:

  • Significant biomechanical deficit
  • Bilateral presentation, if through a thorough history, systemic factors as well as mechanical factors are suspected.

Initial Patient Directed Treatment Options

Plantar Fasciitis only

  • Exercise Prescription
    • Both specific plantar fascia and achilles tendon stretches should be used. See Plantar Heel Pain Booklet.
  • Heel Raise
    • These should be given bilaterally so as to avoid Leg Length Discrepancy
  • Anti Pronation Strapping or Taping
    • Can be useful for a short period for pain relief and to aid in the differential diagnosis of heel pain and future treatment options. Remember to ask the patient about potential skin allergies before use.
    • Low Dye Taping

Fat Pad Atrophy only

  • Heel pad
    • This may be supplied if available or patient can be directed to buy these

Non evidenced treatments

The following treatments are not supported by high quality evidence therefore they should not be considered as a treatment option for patients unless all other evidenced treatments have been tried unsuccessfully and there is clear clinical justification as to why these treatments are being used.

  • Acupuncture/dry needling
    • Insufficient evidence to support use in this condition
  • Low Level Laser Therapy LLLT
    • Some limited evidence but more research needed to determine optimum dosage to provide a significant effect
  • Therapeutic Ultrasound
    • Minimal benefit and no conclusion on effective dosage parameters
    • Electrotherapy
  • Night splints
    • No great evidence of therapeutic benefit with night splints

If patients are not improving as expected they should be referred on to another AHP who can deliver an escalated evidenced intervention or referred to orthopaedics as per the escalation guidance on the pathway.

Second line intervention

  • Biomechanical assessment and potential prescription of Foot Orthoses
    • Address biomechanical deficit if indicated by assessment.
    • Off the shelf or custom made insoles should be prescribed dependant on the severity of biomechanical deficit
    • The orthotic prescription should be decided by the clinician, who should describe the prescription in detail in the patient records

  • Manual therapy
    • consisting of joint and soft tissue mobilisation

NOTE Corticosteroid Injections

Corticosteroid injection has historically been used as a first-tier intervention for heel pain/plantar fasciitis, however this treatment should not be used in either the first or second line intervention because there is limited evidence supporting the effectiveness and the benefits do not offset the risk of harms, including long-term disablement.

The results of 2 systematic reviews failed to yield evidence favouring any substantive clinical benefit of corticosteroid injection for patients with heel pain/plantar fasciitis. Potential harms associated with corticosteroid injection may include injection-site pain, infection, subcutaneous fat atrophy, skin pigmentation changes, plantar fascia rupture, peripheral nerve injury, and muscle damage.

Third line intervention

Corticosteroid injection

  • Ultrasound guided injection is not necessary in most cases and should only be considered in cases which are complex and a normal injection has failed or is assessed as having a high likelihood of failure.

Orthopaedic opinion

One reason for referring to the orthopaedic department is for a surgical opinion. This is not a guarantee that surgery is the correct option for your patient so it’s important that this is not the expectation given to the patient by the referring clinician.

It is important that the patient has the option of a surgical opinion if this may be an appropriate treatment option for them so that they can discuss what is involved in surgery and make an informed decision.

Common conditions which are operated on include: hallux valgus, hallux rigidus, Morton’s neuroma, lesser toe issues, tendon pathology and degenerative changes of the joints of the foot and ankle.

The indications for surgery include persistent pain, worsening symptoms, significant limited mobility or failure of conservative therapy.

Foot and ankle surgery is generally successful with many of the common foot operations achieving 85% success rate, however complications can occur and will be considered as part of the decision making process for surgery.

Remember to exhaust all conservative means ie: orthotics, footwear advice , physiotherapy, pain relief medication , if appropriate steroid injections, before considering surgical opinion.

Further Investigation

The other reason for referral to Orthopaedics is for “Further Investigations”.

MRI and CT are helpful and can be arranged within orthopaedics as appropriate – if your patient does not have a clear diagnosis or there is a concern about a diagnosis and as above, struggling with symptoms, referral on to orthopaedics is appropriate.

Things to consider before referring for further investigation are the severity of the symptoms and whether there are odd/suspicious symptoms making it difficult to make a clear diagnosis.

Things to consider before referring to Orthopaedics:

Before referring to orthopaedics ensure the following:

  • Vascular status – palpable pulses (for surgery)
  • Patient is happy to attend for further review, possible further investigation and possible surgery as an outcome.
  • Conservative means have been attempted.

This is a referral guide however please do not hesitate to contact your local ESP Orthopaedic clinician if you are unsure whether to refer.
