Plantar Fasciitis – Heel Pain Introduction
The London Foot and Ankle Centre has a dedicated Heel Pain Clinic for the rapid assessment and effective treatment of heel pain or plantar fasciitis.
One in ten people will experience heel pain and for many, the problem will have a very significant impact upon their lives.
The treatment for plantar fasciitis Heel Pain Clinic has been established to provide a comprehensive service, offering the full range of advanced treatment options for people with long term, intractable heel pain.
At our dedicated clinic, you can normally have your assessment, x-rays, opinion and first treatment all during your first visit.
Plantar Fasciitis – Heel Pain Symptoms
About heel pain
There are two main types of heel pain, occurring in different places. A small number of people will have pain in both areas of the heel.
The ‘grumbling’ Achilles – non-insertional Achilles tendinopathy
The ‘grumbling’ Achilles is known medically as non-insertional Achilles tendinopathy. Although a rupture of the Achilles is well known, it is actually more common to have what is known as a grumbling Achilles. The pain is felt at the back of the heel above where the Achilles tendon joins the bone. It feels stiff and swollen, particularly in the morning and can prevent the sufferer from taking part in sport. Sometimes the pain is lower down where the tendon joins the bone. This Insertional Achilles tendinopathy is less common.
Policeman’s heel – plantar fasciitis
Policeman’s heel is known medically as plantar fasciitis because it occurs in a tendon called the fascia. The fascia is a strong band of tissue stretching from your heel to your toe bones. It supports the arch of your foot and acts as a shock absorber in the foot. Pain is felt at the bottom of the heel where it connects with the ground in each step. Pain and stiffness often leaves patients “hobbling” for the first few minutes in the morning. The pain can be severe, especially after standing for a long time. Plantar fasciitis is very common indeed and one of the main reasons for seeing a foot specialist.
Causes of Plantar Fasciitis – Heel Pain
The causes of both types of heel pain are not fully understood, but are linked to wear and tear of the tendons and an incomplete healing process. The wear and tear, whether as a result of sport or a gradual, cumulative effect, causes the tendon to thicken. It becomes painful and inflexible. The cause of wear and tear varies from one individual, but may be due to:
- Doing too much, particularly sport which has a high impact on the heel, such as long distance running
- Doing too little and becoming overweight due to sedentary lifestyle and therefore putting the heel under excess pressure
Having very tight calf muscles. This is a problem some people are simply born with. The effect of having very tight muscles is like walking permanently on tip toes, putting the Achilles tendon and the arch of the foot under increased strain.
Diagnosis for Plantar Fasciitis – Heel Pain
How do we assess the best treatment for each patient?
“The initial assessment must be very accurate to ensure the treatment selected will be effective. We listen carefully to the patient – if they describe their heel pain as feeling like hot coal and their calf is extremely tight, we cannot expect shockwave therapy or injections to work. It would be like a boy Scout throwing a small bucket of water on a large fire.”
Matthew Solan, Consultant Orthopaedic Surgeon, the London Foot and Ankle Centre
Our consultant orthopaedic foot and ankle surgeons will carry out a full examination of your foot. This is combined with an ultrasound scan, undertaken and assessed on the same day as your initial visit to the clinic. If for example the examination shows the calf is extremely tight, we will recommend surgical calf stretching because injections or shockwave therapy will not work.
We use specialist ultrasound called a Doppler scan which provides a very detailed image of blood flow in the affected area. For some patients, the scan shows a process known medically as neovascularity. The surgeon can see there are too many small vessels feeding the tendon, perpetuating the swelling and pain. Small nerves follow the vessels. If this is the case, injections are helpful.
Plantar Fasciitis – Heel Pain Treatment
How is heel pain treated?
The first line of treatment for heel pain should always be calf stretching exercises. You should be seen by a physiotherapist who will demonstrate exactly how to do calf stretching exercises correctly. Footwear modifications can also be very helpful – simple heel cushions relieve pressure from the painful part of your heel. We recommend that you try first line treatment for two to three months before moving on to further treatment. Eight to nine out of ten patients with heel pain find the pain eases with stretching exercises.
At the Heel Pain Clinic, we see many patients who are still in significant pain despite trying conservative treatment. For this group of patients we offer:
- Extracorporeal shockwave therapy
- A course of injections
- Surgical calf stretching
Shockwave therapy for heel pain
If shockwave therapy is indicated as the best treatment for your heel pain, you will have your first session during your initial visit to the Heel Pain Clinic.
Each session takes approximately 3–5 minutes. You will lie on your front while the shockwave is applied with a machine rather like a small pneumatic press.
Patients experience some discomfort during the procedure and there may be a little redness on the skin after treatment. Exceptionally, the heel pain becomes slightly worse after treatment before getting better. A total of three sessions are needed, with no more than one to two weeks between each session.
We use the latest shockwave therapy machine, called the Swiss Dolar Clast. This is more effective than older machines which focused energy on a limited area, or ‘pin-head’. The new technology works by emitting the energy like the ripples from throwing a stone into water.
How does shockwave therapy for heel pain work?
It is understood that shockwave therapy works in two ways:
- Shockwaves cause micro damage to tissue in the affected area and in so doing, stimulate healing. Nature gets a second chance.
- The treatment has a directeffect on the nerve endings which make them less sensitive and therefore less likely to transmit pain.
The benefit of shockwave therapy for heel pain is often not felt until after the third session. The treatment works well for 80 per cent of patients. The effect of the treatment is usually permanent and there is no need to return for further sessions at a later date.
NICE (National Institute for Health and Clinical Excellence) recently evaluated shockwave therapy for heel pain in August 2009. The recommendation was that the treatment is effective and should be offered, providing centres audit their results and inform patients of possible side-effects. You can read the guidelines on the NICE website: www.nice.org.uk
What evidence is there that shockwave therapy for heel pain works?
LFAC Consultant Orthopaedic Surgeon Mr Matthew Solan and Consultant Radiologist Dr Andrew Carne are among a small number of UK specialists to be trained by ATRAD. This is an international Association for Radial Pain Therapy, which is at the forefront of training, researching and developing technology in this field.
Mr Solan and Dr Carne adhere to NICE guidance and also are registered with ASSERT, a data collection study for Shockwave treatment. They have both published research on their work and results.
Surgical calf stretching
“If you imagine the lower leg like a rasher of bacon, the calf muscle has a rind. You can only stretch the bacon itself so far because the rind remains tight and limits flexibility. If we carefully cut the rind the rasher can be stretched further. In real life the gap in the “rind” fills with scar tissue – but the rind is then longer. Surgical calf stretching is a way of stretching the tight calf muscle in a very controlled way and allow release of strain from the affected heel area.”
Matthew Solan, Consultant Orthopaedic Surgeon, the London Foot and Ankle Centre
Surgical calf stretching, known medically as Gastrocnemius Release is an established procedure, further developed by Consultant Orthopaedic Surgeon Matthew Solan for the treatment of heel pain. It is carried out as a day procedure and is minimally invasive, using a very small incision behind the knee.
Injections for heel pain
Injections are particularly helpful for people with neovascularity, when the Doppler scan shows there is a large number of small veins feeding a swollen tendon and perpetuating the pain. A course of three injections is normally given, with several weeks between each injection. Injections are undertaken with ultrasound guidance to ensure the injection reaches the target area.
