Inferior Calcaneal Spur
Although many people with plantar fasciitis have heel spurs, spurs are not the cause of plantar fasciitis pain. One out of 10 people has heel spurs, but only 1 out of 20 people (5%) with heel spurs has foot pain. Because the spur is not the cause of plantar fasciitis, the pain can be treated without removing the spur.
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.
Symptoms may be similar to those of plantar fasciitis and include pain and tenderness at the base of the heel, pain on weight bearing and in severe cases difficulty walking. The main diagnosis of a heel spur is made by X-ray where a bony growth on the heel can be seen. A heel spur can occur without any symptoms at all and the athlete would never know they have the bony growth on the heel. Likewise, Plantar fasciitis can occur without the bone growth present.
Diagnosis of a heel spur can be done with an x-ray, which will be able to reveal the bony spur. Normally, it occurs where the plantar fascia connects to the heel bone. When the plantar fascia ligament is pulled excessively it begins to pull away from the heel bone. When this excessive pulling occurs, it causes the body to respond by depositing calcium in the injured area, resulting in the formation of the bone spur. The Plantar fascia ligament is a fibrous band of connective tissue running between the heel bone and the ball of the foot. This structure maintains the arch of the foot and distributes weight along the foot as we walk. However, due to the stress that this ligament must endure, it can easily become damaged which commonly occurs along with heel spurs.
Non Surgical Treatment
Rest won?t help you in case of pain from the heel spur. When you get up after sleeping for some time, the pain may get worse. The pain worsens after a period of rest. You will feel pain because the plantar fascia elongates during working which stresses the heel. It is important to see a doctor if you are having consistent pain in you heel. The doctors may advise few or all of the conservative treatments, stretching exercises, shoe recommendations, shoe inserts or orthotic devices, physical therapy, taping or strapping to rest stressed muscles and tendons. There are some over-the-counter medicines available for treatment of heel pain. Acetaminophen (Tylenol), ibuprofen (Advil), or naproxen (Aleve) are some such medicines which can help you to get relief from the pain. In case of biomechanical imbalances causing the pain, a functional orthotic device can help you to get relief. Your doctor may also advise a corticosteroid injection for eliminating the inflammation.
Usually, heel spurs are curable with conservative treatment. If not, heel spurs are curable with surgery, although there is the possibility of them growing back. About 10% of those who continue to see a physician for plantar fascitis have it for more than a year. If there is limited success after approximately one year of conservative treatment, patients are often advised to have surgery.
You can help prevent heel spur symptoms from returning by wearing the proper shoes. Customized orthotics and insoles can help relieve pressure. It is important to perform your exercises to help keep your foot stretched and relaxed.
