Plantar fasciitis is a condition characterised by damage and inflammation to the plantar fascia (i.e. the connective tissue on the sole of the foot forming the inner arch. This usually occurs at the attachment of the plantar fascia to the heel bone. Plantar fasciitis is the most common cause of heel pain seen in clinical practice. During walking or running, tension is placed through the plantar fascia. When this tension is excessive (often due to poor foot biomechanics such as flat feet or if it is too repetitive or forceful, damage to the plantar fascia can occur. Plantar fasciitis is a condition where there is damage to the plantar fascia with subsequent inflammation and degeneration. This may occur traumatically due to a high force going through the plantar fascia beyond what it can withstand or, more commonly, due to gradual wear and tear associated with overuse. Occasionally, a heel spur may develop in association with plantar fasciitis.
When some people stand/walk/run/jump their own anatomy in their ankle joint is not ‘sturdy’ enough to cope with the needed stabilisation of their ankle joint when they are weight bearing. So, their ankle rotates to find a point of stability. By the shin twisting in and the ankle rotating downwards to the inside (along with your body weight, the power of some muscles, and of course, gravity) a huge amount of stress is applied to the plantar fascia until it is stressed beyond it’s normal limits and it starts to ‘tighten up’. It is this tightening up of the plantar fascia under this stress that causes the damage that in turn leads to pain…eventually.
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
If you protect your injured plantar fascia appropriately the injured tissues will heal. Inflammed structures will settle when protected from additional damage, which can help you avoid long-standing degenerative changes. Plantar fasciitis may take from several weeks (through to many months) to heal while we await Mother Nature to form and mature the new scar tissue, which takes at least six weeks. During this time period you should be aiming to optimally remould your scar tissue to prevent a poorly formed scar that may become lumpy or potentially re-tear in the future. It is important to lengthen and orientate your healing scar tissue via massage, gentle stretches, and light active exercises. In most cases, your physiotherapist will identify stiff joints within your foot and ankle complex that they will need to loosen to help you avoid plantar fascia overstress.A sign that you may have a stiff ankle joint can be a limited range of ankle bend during a squat manoeuvre. Your physiotherapist will guide you.
More invasive procedures to treat plantar fasciitis are usually sought only after other treatment has failed to produce favorable results. Corticosteroid injections deliver medicine into the injured fascia to reduce pain. However, this treatment may weaken the plantar fascia and result in further damage. In addition, extracorporeal shock wave therapy (ESWT) is a treatment where sound waves are sent through the damaged tissue in order to stimulate the damaged tissue and encourage healing. This method is relatively new in treating plantar fasciitis and your doctor will be able to tell you if it is the right method for you. Lastly, surgery is the last option for those suffering from chronic or severe plantar fasciitis.
