Plantar Fasciitis is the Latin term for “inflammation of the plantar fascia”. The plantar fascia is a thick, fibrous ligament that runs under the foot from the heel bone to the toes. It forms the arch of the foot and functions as our natural shock-absorbing mechanism. Unlike muscle tissue, the plantar fascia is not very elastic and therefore is very limited in its capacity to stretch or elongate. Herein lies the problem, when too much traction is placed on the plantar fascia (for various reasons) micro-tearing will occur, resulting in irritation, inflammation and pain. Plantar Fasciitis usually causes pain under the heel. However some people may experience pain under the arch of the foot. Both heel pain and arch discomfort are related to Plantar Fasciitis, with heel pain being far more common than arch pain.
Patients with tight calf muscles will suffer with excessive pulling of the muscle group on the back of the heel. This in turn creates pulling of other structures that are attached to the heel, including the Plantar Fascia. When the pulling continues for long enough, then inflammation will develop and lead to Plantar Fasciitis. This causes Heel Pain. It is extremely common for patients who increase their level of activity to develop Plantar Fasciitis. Boot camp, running, zumba, recreational walking or other quick movement sports such as tennis or touch football are typical causes of Heel Pain. The sharp increase in exercise is too much for the foot to cope with and the stress on the Plantar Fascia causes inflammation. The Heel Pain that is caused by this inflammation is known as Plantar Fasciitis.
Heel pain is the most common symptom associated with plantar fasciosis. Your heel pain may be worse in the morning or after you have been sitting or standing for long periods. Pain is most common under your heel bone, but you also may experience pain in your foot arch or on the outside aspect of your foot. Other common signs and symptoms of plantar fasciosis include mild swelling and redness in your affected area, tenderness on the bottom of your heel, impaired ability to ambulate.
Physical examination is the best way to determine if you have plantar fasciitis. Your doctor examines the affected area to determine if plantar fasciitis is the cause of your pain. The doctor may also examine you while you are sitting, standing, and walking. It is important to discuss your daily routine with your doctor. An occupation in which you stand for long periods of time may cause plantar fasciitis. An X-ray may reveal a heel spur. The actual heel spur is not painful. The presence of a heel spur suggests that the plantar fascia has been pulled and stretched excessively for a long period of time, sometimes months or years. If you have plantar fasciitis, you may or may not have a heel spur. Even if your plantar fasciitis becomes less bothersome, the heel spur will remain.
Non Surgical Treatment
If conservative treatments fail, and the symptoms of plantar fasciitis have not been relieved, the doctor may recommend one of the following treatments. Cortisone, or corticosteroids, is medications that reduce inflammation. Cortisone is usually mixed with local anesthetics and injected into the plantar fascia where it attaches to the heel bone. In many cases this reduces the inflammation present and allows the plantar fascia to begin healing. Local injections of corticosteroids may provide temporary or permanent relief. Recurrence of symptoms may be lessened by combining steroid injections with other forms of treatment such as orthotics, changes in shoe gear, weight loss, stretching exercises, and rest. Repeated cortisone injections may result in rupture of the plantar fascia, thinning of the heel’s fat pad, and other tissue changes. Extracorporeal Shock Wave Therapy (ESWT) devices generate pulses of high-pressure sound that travel through the skin. For reasons that are not fully understood, soft tissue and bone that are subjected to these pulses of high-pressure energy heal back stronger. There is both a high-energy and low-energy form of ESWT; and both forms of shock wave therapy can be used in the treatment of plantar fasciitis. Research studies indicate ESWT is a safe and effective treatment option for plantar fasciitis. The recovery period is shorter than traditional invasive surgery and the procedure eliminates many of the risks associated with traditional surgery.
Plantar fasciotomy is often considered after conservative treatment has failed to resolve the issue after six months and is viewed as a last resort. Minimally invasive and endoscopic approaches to plantar fasciotomy exist but require a specialist who is familiar with certain equipment. Heel spur removal during plantar fasciotomy has not been found to improve the surgical outcome. Plantar heel pain may occur for multiple reasons and release of the lateral plantar nerve branch may be performed alongside the plantar fasciotomy in select cases. Possible complications of plantar fasciotomy include nerve injury, instability of the medial longitudinal arch of the foot, fracture of the calcaneus, prolonged recovery time, infection, rupture of the plantar fascia, and failure to improve the pain. Coblation (TOPAZ) surgery has recently been proposed as alternative surgical approaches for the treatment of recalcitrant plantar fasciitis.
It is not always possible to prevent heel pain, but there are measures you can take to help avoid further episodes. Healthy weight. Being overweight can place excess pressure and strain on your feet, particularly on your heels. This increases the risk of damaging your feet and heels. If you are overweight, losing weight and maintaining a healthy weight by combining regular exercise with a healthy, balanced diet can be beneficial for your feet. You can calculate your body mass index (BMI) to find out whether you are a healthy weight for your height and build. To work out your BMI, divide your weight in kilograms by your height in metres squared. A BMI of less than 18.5 means that you are underweight, 18.5-24.9 means that your weight is healthy, 25-29 means that you are overweight, 30-40 means that you are obese, over 40 means that you are morbidly obese. You can also use the BMI healthy weight calculator to work out your BMI. Healthy feet. You should always wear footwear that is appropriate for your environment and day-to-day activities. Wearing high heels when you go out in the evening is unlikely to be harmful. However, wearing them all week at work may damage your feet, particularly if your job involves a lot of walking or standing. Ideally, you should wear shoes with laces and a low to moderate heel that supports and cushions your arches and heels. Avoid wearing shoes with no heels.
