Plantar fasciitis

A common cause of heel pain. It is inflammation of the sheet of tissue (plantar fascia), that forms the arch of the foot, going from the heel to the toes. It results from overuse or being overstretched, causing inflammation and micro-tears. Can occur after a recent change in foot wear or activities.


Symptoms

Pain is typically described as a stabbing pain under the foot and heel. Patients often complain of pain when starting to weight-bear, it can then ease off with more weight-bearing (as it stretches) but returns with prolonged weightbearing (overuse).




Non-operative management

In my experience most plantar fasciitis will settle with a combination of initial measures including analgesics, non-steroidal anti-inflammatory medication and stretching exercises. The stretching exercises may be Plantar Fascia Specific Stretching exercises alone or in combination with calf stretching.


The key to success is compliance with the stretching regime.

Night splints may also be utilised to keep the fascia stretched – this prevents the plantar fascia from returning to its normal resting position at night which becomes painful when stretched in the morning.


However, I find compliance with this poor as it is quite uncomfortable for the patient and therefore do not routinely utilise this. If despite these measures, there has been little benefit I do suggest extracorporeal shock wave therapy in combination with further stretching as evidence suggests combination treatment has better outcomes.

Shockwave therapy transmits high frequency shockwave impulses to the area of inflammation. This helps break down the scarring that is often present with inflammation and allows the stretching exercises to be carried out effectively.

If symptoms remain or return, the next step is to consider needling of the fascia and injection with corticosteroid. I perform this procedure under sedation in an operating theatre as the needling can be quite painful. During this procedure I use a hypodermic needle to scratch the scarred plantar fascia off its insertion to help break it down to allow stretching. Corticosteroid is also administered after the needling to help reduce inflammation.


The key to this is that the needling allows stretching, however without regular stretching the problem will return.


Operative management

From my experience I find operative intervention for plantar fasciitis provides a guided outcome and therefore I try more predictable non-operative measures routinely.

If surgical intervention is required due to non-resolving symptoms despite non-operative management, I will discuss the specific risks associated with the surgery.

If the plantar fascia pain is an isolated problem, the procedure involves an incision on the inner aspect of the back of the heel to release the plantar fascia and release a nerve that is often entrapped.

In the situation where there is tight calf musculature, surgery maybe suggested to alleviate this, if stretching has not worked, and this has a more predictable outcome associated with higher patient satisfaction.


Rehabilitation

You will find your foot in heavy bandaging and a walking boot will be applied before you go home. You will be provided with crutches for support, and you will be permitted to weight-bear in the boot. Elevation, as much as possible, is important in the first few weeks. This boot will be removed in 2 weeks’ time for a wound check and physiotherapy will be started.



Complications

As with any surgery there are potential risks. This will be discussed in more detail during the consultation, however common complications are stiffness, swelling, nerve injury, infection, failure for symptoms to settle and irritation from the wound.



Can the plantar spur be removed?

I am often asked to see patients to consider removal of their plantar spur. This is not something I routinely perform, as evidence suggests that whilst a spur is suggestive of plantar fasciitis it is not causative for the symptoms and removal does not resolve symptoms. In fact, many patients without plantar fasciitis also have spurs present on x-ray.



The role of Platelet-rich plasma (PRP) injections

This is something I also frequently get asked about. There is little evidence for their benefit at the moment. Whilst it cannot be discounted, there is very little evidence available at the moment to recommend its use.
