The plantar fascia is connective tissue on the sole of your foot. When the arch of the foot is not properly supported, the plantar fascia can stretch and pull away from the heel area. When the plantar fascia pulls away from the heel, calcium deposits form in its absence. These calcium deposits are called heel spurs and can be very painful.
Each time we take a step forward, all of our body weight first rests on the heel of one foot. As our weight moves forward, the entire foot begins to bear the body’s weight, and the foot flattens and this places a great deal of pressure and strain on the plantar fascia. There is very little ?give? to the plantar fascia, so as it stretches only slightly, it pulls on its attachment to the heel. If the foot is properly aligned this pull causes no problems. However, if the foot is ?pronated?(the foot rolls outward at the ankle, causing a break down of the inner side of the shoe), the arch falls excessively, and this causes an abnormal stretching of the relatively inflexible plantar fascia, which in turn pulls abnormally hard on the heel. The same pathology occurs with ?supination? (the rolling inward of the foot, causing a break down of the outer side of the shoe). Supinated feet are relatively inflexible; usually have a high arch, and a short or tight plantar fascia. Thus as weight is transferred from the heel to the remainder of the foot, the tight plantar fascia hardly stretches at all, and pulls with great force on its attachment to the heel. In both cases, the abnormal stress placed on the attachment of the plantar fascia to the heel usually causes pain, inflammation, and possibly swelling. If this process continues, the plantar fascia partially tears away from the heel. The body will fill in this torn area with calcium; eventually it becomes bone, and a heel spur results.
Heel spurs can be quite painful, but can just as likely occur with no symptoms at all. Plantar fasciitis is a contributing condition to heel spurs. The cause of the pain is not the heel spur itself but the soft-tissue injury associated with it. The feeling has been described as a knife or pin sticking into the bottom of your feet when you first stand up after sitting or laying down for a long period of time – a pain that later turns into a dull ache.
The proper diagnosis of a heel spur often requires an X-ray. To make this process as convenient for his patients as possible, most clinics have an on-site digital X-ray and diagnostic ultrasound machines. This can make it unnecessary for patients to visit diagnostic imaging centers, allowing patients to receive more expedient treatment.
Non Surgical Treatment
Heel spurs and plantar fascitis are usually controlled with conservative treatment. Early intervention includes stretching the calf muscles while avoiding re-injuring the plantar fascia. Decreasing or changing activities, losing excess weight, and improving the proper fitting of shoes are all important measures to decrease this common source of foot pain. Modification of footwear includes shoes with a raised heel and better arch support. Shoe orthotics recommended by a healthcare professional are often very helpful in conjunction with exercises to increase strength of the foot muscles and arch. The orthotic prevents excess pronation and lengthening of the plantar fascia and continued tearing of this structure. To aid in this reduction of inflammation, applying ice for 10-15 minutes after activities and use of anti-inflammatory medication can be helpful. Physical therapy can be beneficial with the use of heat modalities, such as ultrasound that creates a deep heat and reduces inflammation. If the pain caused by inflammation is constant, keeping the foot raised above the heart and/or compressed by wrapping with an ace bandage will help. Corticosteroid injections are also frequently used to reduce pain and inflammation. Taping can help speed the healing process by protecting the fascia from reinjury, especially during stretching and walking.
Surgery is used a very small percentage of the time. It is usually considered after trying non-surgical treatments for at least a year. Plantar fascia release surgery is use to relax the plantar fascia. This surgery is commonly paired with tarsal tunnel release surgery. Surgery is successful for the majority of people.
