Plantar fasciitis, also called “heel pain syndrome,” affects approximately 2 million people in the United States each year. Plantar fasciitis can come on gradually as the result of a degenerative process or sudden foot trauma. It can appear in one heel or both. It is generally worse on taking the first few steps in the morning or after prolonged sitting or non-weight-bearing movement. Symptoms can be aggravated by activity and prolonged weight bearing. Obesity, too, is hard on the feet-it can cause plantar pain or it can make that pain worse. The plantar fascia connects the calcaneal tubercle to the forefoot with five slips directed to each toe respectively. Other conditions, such as calcaneal fat pad atrophy, calcaneal stress fracture, nerve entrapment, and rheumatoid arthritis may also cause foot pain. These conditions may be found in combination with plantar fasciitis, or separate from it. A blood test can help pinpoint the cause(s).
Plantar Fasciitis is simply caused by overstretching of the plantar fascia ligament under the foot. So why is the ligament being overstretched? There are different factors, over-use, too much sports, running, walking or standing for long periods (e.g. because of your job) weight gain, our feet are designed to carry a ‘normal’ weight. Any excess weight places great pressure on the bones, nerves, muscles and ligaments in the feet, which sooner or later will have consequences. Even pregnancy (in the last 10 weeks) can cause foot problems! age, as we get older ligaments become tighter & shorter and msucles become weaker; the ideal circumstances for foot problems, unsupportive footwear, ‘floppy’ shoes with no support as well as thongs affect our walking pattern, walking barefoot, especially on hard surfaces like concrete or tiles, low arch and flat feet or over-pronation. An important contributing factor to Plantar Fasciitis is ‘excess pronation’ (or over-pronation). This is a condition whereby the feet roll over, the arches collapse and the foot elongates. This unnatural elongation puts excess strain on the ligaments, muscles and nerves in the foot. When the foot is not properly aligned, the bones unlock and cause the foot to roll inward. With every step taken your foot pronates and elongates, stretching the plantar fascia and causing inflammation and pain at the attachment of the plantar fascia into the heel bone. Re-alignment of the foot should therefore an important part of the treament regime.
If you have Plantar Fasciitis, you will most likely feel a sharp pain under the ball of you heel and it will often give pain when standing after a period of rest. For example when you get out of bed in the mornings or after being sat down. Some patients describe this feeling as a stone bruise sensation, or a pebble in the shoe and at times the pain can be excruciating. Patients with Plantar Fasciitis can experience pain free periods whereby the think they are on the mend, only for the heel pain to come back aggressively when they appear to have done nothing wrong. If your plantar fasciitis came on very suddenly and the pain is relentless, then you may have Plantar Fascial Tears. We will be able to differentiate between these 2 conditions, sometimes with ultra sound imaging. The treatment for each of these conditions will need to be very different.
Plantar fasciitis is usually diagnosed by a health care provider after consideration of a person’s presenting history, risk factors, and clinical examination. Tenderness to palpation along the inner aspect of the heel bone on the sole of the foot may be elicited during the physical examination. The foot may have limited dorsiflexion due to tightness of the calf muscles or the Achilles tendon. Dorsiflexion of the foot may elicit the pain due to stretching of the plantar fascia with this motion. Diagnostic imaging studies are not usually needed to diagnose plantar fasciitis. However, in certain cases a physician may decide imaging studies (such as X-rays, diagnostic ultrasound or MRI) are warranted to rule out other serious causes of foot pain. Bilateral heel pain or heel pain in the context of a systemic illness may indicate a need for a more in-depth diagnostic investigation. Lateral view x-rays of the ankle are the recommended first-line imaging modality to assess for other causes of heel pain such as stress fractures or bone spur development. Plantar fascia aponeurosis thickening at the heel greater than 5 millimeters as demonstrated by ultrasound is consistent with a diagnosis of plantar fasciitis. An incidental finding associated with this condition is a heel spur, a small bony calcification on the calcaneus (heel bone), which can be found in up to 50% of those with plantar fasciitis. In such cases, it is the underlying plantar fasciitis that produces the heel pain, and not the spur itself. The condition is responsible for the creation of the spur though the clinical significance of heel spurs in plantar fasciitis remains unclear.
Non Surgical Treatment
Treatment for heel pain usually involves using a combination of techniques, such as stretches and painkillers, to relieve pain and speed up recovery. Most cases of heel pain get better within 12 months. Surgery may be recommended as a last resort if your symptoms don’t improve after this time. Only 1 in 20 people with heel pain will need surgery. Whenever possible, rest the affected foot by not walking long distances and standing for long periods. However, you should regularly stretch your feet and calves using exercises such as those described below. Pain relief. Non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, can be used to help relieve pain. Some people also find applying an ice pack to the affected heel for 5-10 minutes can help relieve pain and inflammation. However, do not apply an ice pack directly to your skin. Instead, wrap it in a towel. If you do not have an ice pack, you can use a packet of frozen vegetables.
If treatment hasn’t worked and you still have painful symptoms after a year, your GP may refer you to either an orthopaedic surgeon, a surgeon who specialises in surgery that involves bones, muscles and joints, a podiatric surgeon, a podiatrist who specialises in foot surgery. Surgery is sometimes recommended for professional athletes and other sportspeople whose heel pain is adversely affecting their career. Plantar release surgery. Plantar release surgery is the most widely used type of surgery for heel pain. The surgeon will cut the fascia to release it from your heel bone and reduce the tension in your plantar fascia. This should reduce any inflammation and relieve your painful symptoms. Surgery can be performed either as, open surgery, where the section of the plantar fascia is released by making a cut into your heel, endoscopic or minimal incision surgery – where a smaller incision is made and special instruments are inserted through the incision to gain access to the plantar fascia. Endoscopic or minimal incision surgery has a quicker recovery time, so you will be able to walk normally much sooner (almost immediately), compared with two to three weeks for open surgery. A disadvantage of endoscopic surgery is that it requires both a specially trained surgical team and specialised equipment, so you may have to wait longer for treatment than if you were to choose open surgery. Endoscopic surgery also carries a higher risk of damaging nearby nerves, which could result in symptoms such as numbness, tingling or some loss of movement in your foot. As with all surgery, plantar release carries the risk of causing complications such as infection, nerve damage and a worsening of your symptoms after surgery (although this is rare). You should discuss the advantages and disadvantages of both techniques with your surgical team. Extracorporeal shockwave therapy (EST) is a fairly new type of non-invasive treatment. Non-invasive means it does not involve making cuts into your body. EST involves using a device to deliver high-energy soundwaves into your heel. The soundwaves can sometimes cause pain, so a local anaesthetic may be used to numb your heel. It is claimed that EST works in two ways. It is thought to, have a “numbing” effect on the nerves that transmit pain signals to your brain, help stimulate and speed up the healing process. However, these claims have not yet been definitively proven. The National Institute for Health and Care Excellence (NICE) has issued guidance about the use of EST for treating plantar fasciitis. NICE states there are no concerns over the safety of EST, but there are uncertainties about how effective the procedure is for treating heel pain. Some studies have reported that EST is more effective than surgery and other non-surgical treatments, while other studies found the procedure to be no better than a placebo (sham treatment).
Do your best to maintain healthy weight. Plantar fasciitis is caused by wear and tear on your feet. Being overweight drastically increases the pounding your feet take every day. Even losing a few pounds can help reduce heel pain. Avoid jobs that require walking or standing for long periods of time. Having your body weight on your feet all day puts a lot of pressure on your plantar fascia tissue. Replace your shoes on a regular basis. Buy new shoes when the old ones are worn-out. Make sure your shoes will fit your foot size comfortably at the end of the day. Pay attention to the width as well as the length. Use good supportive shoes that will help you with your original problem like arch support, motion control, stability, cushioning etc. Stretch regularly as part of your daily routine. There are a few special stretching techniques for the prevention. Choose soft surfaces for your exercise routine to walk, jog or run on. Rest and elevate your feet every chance you have. Strengthen your foot muscles as part of your exercise routine. Strong foot muscles provide a good support to the plantar fascia. Change your shoes during the work week. Don’t wear the same pair of shoes every day. Perform Warm up exercises such as a short period of walking, a light jog or other easy movement and then stretch before starting the main exercise. Try to avoid dramatic changes in your exercise routine. Increase your exercise level gradually. Don’t run long distance if you are used to walk. Make the change slowly and gradually. Pay attention to your foot pain, do not ignore it. Visit your doctor if the pain continues. Avoid the activities that cause you pain. Use over-the-counter Orthotics or inserts that your doctor may prescribe. Off-the-shelf or custom-fitted arch supports (orthotics) will help distribute pressure to your feet more evenly. Try to avoid barefoot walking, since it may add stress on the plantar fascia ligament.
