What Brings About Plantar Fasciitis

Overview

Plantar Fasciitis is actually, in most cases, plantar fasciosis but it’s a bit like pen/biro or hoover/vacuum. The term ‘-itis‘ means ‘inflammation’. This is a term we use for this problem in the early stages of damage because it usually is quite literally an inflammation of part of the plantar fascia. So, what is commonly known as ‘plantar fasciitis’ is really ‘plantar fasciosis’ - a degradation or degeneration of the collagen fibres because of prolonged (most of your adult life) unsustainable stress being applied to the fascia. So, we call it plantar fasciitis but it usually hasn’t been an ‘-itis‘ for years and that is why in many cases anti-inflammatory drugs do not help ease the pain of walking. This is also why most sufferers experience pain first thing in the morning. If inflammation was the source of discomfort then why would it hurt after a nights rest and the good old drugs pumping through your system.




Causes

The cause of plantar fasciitis is often unclear and may be multifactorial. Because of the high incidence in runners, it is best postulated to be caused by repetitive microtrauma. Possible risk factors include obesity, occupations requiring prolonged standing and weight-bearing, and heel spurs. Other risk factors may be broadly classified as either extrinsic (training errors and equipment) or intrinsic (functional, structural, or degenerative). Training errors are among the major causes of plantar fasciitis. Athletes usually have a history of an increase in distance, intensity, or duration of activity. The addition of speed workouts, plyometrics, and hill workouts are particularly high-risk behaviors for the development of plantar fasciitis. Running indoors on poorly cushioned surfaces is also a risk factor. Appropriate equipment is important. Athletes and others who spend prolonged time on their feet should wear an appropriate shoe type for their foot type and activity. Athletic shoes rapidly lose cushioning properties. Athletes who use shoe-sole repair materials are especially at risk if they do not change shoes often. Athletes who train in lightweight and minimally cushioned shoes (instead of heavier training flats) are also at higher risk of developing plantar fasciitis.




Symptoms

Plantar fasciitis which usually occurs on one foot at a time typically develops slowly. Some cases can be sudden and severe. If you suspect that you have plantar fasciitis, you should feel a sharp, stabbing heel pain, usually in the inside bottom part of the heel. The pain will likely be worse when you take the first steps after long periods of rest (especially after sleep). The pain may also worsen as you stand, climb stairs, or tiptoe. You typically will not feel a lot of pain during exercise, but will feel the ache after. In some cases, the affected heel may even swell.




Diagnosis

A thorough subjective and objective examination from a physiotherapist is usually sufficient to diagnose plantar fasciitis. Occasionally, further investigations such as an X-ray, ultrasound or MRI may be required to assist with diagnosis and assess the severity of the condition.




Non Surgical Treatment

There are a number of treatments that can help relieve heel pain and speed up your recovery. These include resting your heel, try to avoid walking long distances and standing for long periods, regular stretching, stretching your calf muscles and plantar fascia, pain relief, using an icepack on the affected heel and taking painkillers, such as non-steroidal anti-inflammatory drugs (NSAIDs) wearing good-fitting shoes that support and cushion your foot, running shoes are particularly useful, using supportive devices such as orthoses (rigid supports that are put inside the shoe) or strapping. Around four out of five cases of heel pain resolve within a year. However, having heel pain for this length of time can often be frustrating and painful. In around one in 20 cases, the above treatments are not enough, and surgery may be recommended to release the plantar fascia.






Surgical Treatment

In cases that do not respond to any conservative treatment, surgical release of the plantar fascia may be considered. Plantar fasciotomy may be performed using open, endoscopic or radiofrequency lesioning techniques. Overall, the success rate of surgical release is 70 to 90 percent in patients with plantar fasciitis. Potential risk factors include flattening of the longitudinal arch and heel hypoesthesia as well as the potential complications associated with rupture of the plantar fascia and complications related to anesthesia.
