The plantar fascia is a ligament that connects the heel to the toes on the bottom of the foot. It lies just below the skin layers as it passes over the arch of the foot. A common ailment called plantar fasciitis is the result of this ligament becomes inflamed. This can Foot anatomyhappen from injury, physical stress, or sometimes for no obvious reason. The most common point for this inflammation is where this ligament joints the heel bone. Typical symptoms are the pain on the bottom of the foot near the heel usually most intense in the mornings when arising or after a long period with little movement. The pain typically diminishes with movement. Many suffering from plantar fasciitis have heel spurs. Even though they are in the same area they are unrelated and the heel spurs do not cause the plantar fasciitis. Most times heel spurs will not cause pain and in many go undetected unless they have an x-ray for some other reason.
Plantar Fasciitis is caused by abnormal pronation of the foot. Contributing factors are obesity, weight gain, jobs that require a lot of walking or standing on hard surfaces, badly worn shoes with little support, and also inactivity. As a result of over-pronation, with every step the Plantar Fascia (band of tissue under the foot) is being stretched, resulting in inflammation, irritation and pain at the attachment of the fascia into the heel bone. In some cases the pain is felt under the foot, in the arch. Continuous pulling of the fascia at the heel bone, eventually may lead to the development of bony growth on the heel. This is called a heel spur. When you’re at rest, such as while sleeping, the Plantar Fascia tightens and shortens. When body weight is rapidly applied to the foot, the Fascia must stretch and quickly lengthen, causing micro-tears in the Fascia. As a result, the foot pain is more severe with your first steps in the morning, or after sitting for a long period. Plantar Fasciitis is more likely to happen if you suffer from over-pronation (flattening of the arch), you stand or walk on hard surfaces, for long periods, you are overweight or pregnant, you have tight calf muscles.
The pain associated with plantar fasciitis is typically gradual in onset and is usually located over the inner or medial aspect of the heel. Occasionally, the pain will be sudden in onset, occurring after missing a step or after jumping from a height. The pain is commonly most severe upon arising from bed in the morning, or after periods of inactivity during the day. Thus, it causes what is known as "first-step pain." The degree of discomfort can sometimes lessen with activity during the course of the day or after "warming-up", but can become worse if prolonged or vigorous activity is undertaken. The pain is also often noted to be more severe in bare feet or in shoes with minimal or no padding at the sole.
Your doctor will check your feet and watch you stand and walk. He or she will also ask questions about your past health, including what illnesses or injuries you have had. Your symptoms, such as where the pain is and what time of day your foot hurts most. How active you are and what types of physical activity you do. Your doctor may take an X-ray of your foot if he or she suspects a problem with the bones of your foot, such as a stress fracture.
Non Surgical Treatment
The key for the proper treatment of plantar fasciitis is determining what is causing the excessive stretching of the plantar fascia. When the cause is over-pronation (flat feet), an orthotic with rearfoot posting and longitudinal arch support is an effective device to reduce the over-pronation and allow the condition to heal. If you have usually high arches, which can also lead to plantar fasciitis, cushion the heel, absorb shock and wear proper footwear that will accommodate and comfort the foot. Other common treatments include stretching exercises, plantar fasciitis night splints, wearing shoes that have a cushioned heel to absorb shock, and elevating the heel with the use of a heel cradle or heel cup. Heel cradles and heel cups provide extra comfort, cushion the heel, and reduce the amount of shock and shear forces placed during everyday activities.
Surgery should be reserved for patients who have made every effort to fully participate in conservative treatments, but continue to have pain from plantar fasciitis. Patients should fit the following criteria. Symptoms for at least 9 months of treatment. Participation in daily treatments (exercises, stretches, etc.). If you fit these criteria, then surgery may be an option in the treatment of your plantar fasciitis. Unfortunately, surgery for treatment of plantar fasciitis is not as predictable as a surgeon might like. For example, surgeons can reliably predict that patients with severe knee arthritis will do well after knee replacement surgery about 95% of the time. Those are very good results. Unfortunately, the same is not true of patients with plantar fasciitis.
To reduce your risk of getting plantar fasciitis take these steps. Wear appropriate and well-fitted footwear during sports and exercise. Do stretching exercises for the Achilles tendon and plantar fascia. Increase the intensity and duration of exercise gradually. Maintain an appropriate weight.
