Plantar fasciitis is a painful condition causing heel pain and many people with the condition also have heel spurs. It affects the band of tissue (plantar fascia) that supports the middle part of the foot and runs along the sole of the foot from the heel to the ball of the foot. Usually the plantar fascia is strong and flexible but due to certain factors it can become irritated and inflamed where the plantar fascia joins the bone in the foot. Heel spurs occur when there’s constant pulling of the fascia at the heel bone. This leads to a bony growth or spur. The symptoms of plantar fasciitis are pain in the arch of the foot or heel. This pain is usually worse in the morning after rest when the plantar fascia tightens and shortens. Heel spurs cause a stabbing pain at the bottom or front of the heel bone.
Plantar fasciitis is the most common cause of heel pain, accounting for around four out of five cases. Plantar fasciitis is when the thick band of tissue that connects the heel bone with the rest of the foot (the plantar fascia) becomes damaged and thickened. Damage to the plantar fascia is thought to occur following sudden damage, for example, damaging your heel while jogging, running or dancing; this type of damage usually affects younger people who are physically active, gradual wear and tear of the tissues that make up the plantar fascia – this usually affects adults who are 40 years of age or over. You are at an increased risk of gradual wear and tear damaging your plantar fasciitis if you are overweight or obese, if you have a body mass index (BMI) of 30 or over, you are considered to be obese, have a job that involves spending long periods of time standing, wear flat-soled shoes, such as sandals or flip flops. Less common causes of heel pain are a stress fracture. A stress fracture can occur if your heel bone is damaged during an injury. Fat pad atrophy. Fat pad atrophy is where the layer of fat that lies under the heel bone, known as the fat pad, starts to waste away due to too much strain being placed on the pad. Women who wear high-heeled shoes for many years have an increased risk of developing fat pad atrophy. Bursitis. Bursitis is inflammation of one or more bursa (small fluid-filled sacs under the skin, usually found over the joints and between tendons and bones). It’s possible to develop bursitis anywhere inside the body, not just in the foot. Tarsal tunnel syndrome. The nerves in the sole of your foot pass through a small tunnel on the inside of the ankle joint, known as the tarsal tunnel. If a cyst forms or the tunnel is damaged, the nerves can become compressed (squashed). This can cause pain anywhere along the nerve, including beneath your heel. Sever’s disease. Sever’s disease is a common cause of heel pain in children. It’s caused by the muscles and tendons of the hamstrings and calves stretching and tightening in response to growth spurts. The stretching of the calf muscle pulls on the Achilles tendon. This pulls on the growing area of bone at the back of the heel (growth plate), causing pain in the heel. The pain is further aggravated by activities such as football and gymnastics. The pain often develops at the side of the heel, but can also be felt under the heel. Calf and hamstring stretches and, if necessary, heel pads are usually effective treatments for Sever’s disease. Bone spurs. Bone spurs are an excess growth of bone that forms on a normal bone. Bone spurs can develop on the heel (a heel spur) and are more common in people with heel pain. However, they can also occur in people without heel pain. A heel spur does not cause heel pain.
Plantar fasciitis and heel spur pain usually begins in the bottom of the heel, and frequently radiates into the arch. At times, however, the pain may be felt only in the arch. The pain is most intense when first standing, after any period of rest. Most people with this problem experience their greatest pain in the morning, with the first few steps after sleeping. After several minutes of walking, the pain usually becomes less intense and may disappear completely, only to return later with prolonged walking or standing. If a nerve is irritated due to the swollen plantar fascia, this pain may radiate into the ankle. In the early stages of Plantar Fasciitis and Heel Spurs, the pain will usually subside quickly with getting off of the foot and resting. As the disease progresses, it may take longer periods of time for the pain to subside.
To diagnose plantar fasciitis, your doctor will physically examine your foot by testing your reflexes, balance, coordination, muscle strength, and muscle tone. Your doctor may also advise a magnetic resonance imaging (MRI) or X-ray to rule out other others sources of your pain, such as a pinched nerve, stress fracture, or bone spur.
Non Surgical Treatment
Orthotics are corrective foot devices. They are not the same as soft, spongy, rubber footbeds, gel heel cups etc. Gel and rubber footbeds may cushion the heels and feet, but they do not provide any biomechanical correction. In fact, gel can do the opposite and make an incorrect walking pattern even more unstable! Orthotic insoles work by supporting the arches while re-aligning the ankles and lower legs. Most people’s arches look quite normal when sitting or even standing. However, when putting weight on the foot the arches lower, placing added tension on the plantar fascia, leading to inflammation at the heel bone. Orthotics support the arches, which reduces the tension and overwork of the plantar fascia, allowing the inflamed tissue to heal. Orthotics needn’t be expensive, custom-made devices. A comprehensive Heel Pain study by the American Orthopaedic Foot and Ankle Society found that by wearing standard orthotics and doing a number of daily exercises, 95% of patients experienced substantial, lasting relief from their heel pain symptoms.
The majority of patients, about 90%, will respond to appropriate non-operative treatment measures over a period of 3-6 months. Surgery is a treatment option for patients with persistent symptoms, but is NOT recommended unless a patient has failed a minimum of 6-9 months of appropriate non-operative treatment. There are a number of reasons why surgery is not immediately entertained including. Non-operative treatment when performed appropriately has a high rate of success. Recovery from any foot surgery often takes longer than patients expect. Complications following this type of surgery can and DO occur! The surgery often does not fully address the underlying reason why the condition occurred therefore the surgery may not be completely effective. Prior to surgical intervention, it is important that the treating physician ensure that the correct diagnosis has been made. This seems self-evident, but there are other potential causes of heel pain. Surgical intervention may include extracorporeal shock wave therapy or endoscopic or open partial plantar fasciectomy.
