Heel Spurs should be called a traction spurs because they grow in the same direction that the tendons pull away from the heel bone, which is why it can occur on the bottom of the heel (Plantar Fasciitis) and on the back of the heel (Achilles Tendonitis). Some patients may only develop one type of heel spur, but both these problems are closely related so it's not unusual for a patient to have both heel spurs. It's important to note though that most heel spurs aren't the cause of your heel pain.
Causes of Heel Spur Syndrome are mostly due to your foot structure. Foot structure is due to hereditary for the most part, meaning it was the way you were when born. Other factors such as increase in weight, injury, improper shoes, or different activities may change the way your foot functions as well. If one leg is longer or shorter than the other, this may make your foot function improperly and be the cause of the heel spur syndrome. Improper shoes may be ones that are new or ones that are worn out and do not give good support. The higher priced shoes do not mean it's a better shoe. Pronation is a term used to describe a foot which allows the arch to fall more than normal and allows for the fascia along the bottom of the foot to put a tighter pull or a different angle of pull on the heel bone. Over time, this constant pull of the tight fascia can force the bone to enlarge and form a spur. It is not the heel spur that causes the pain directly. The spur may cause pressure against a nearby nerve causing a neuritis, or a bursa causing a bursitis.
The pain caused by a calcaneal spur is not the result of the pressure of weight on the point of the spur, but results from inflammation around the tendons where they attach to the heel bone. You might expect the pain to increase as you walk on the spur, but actually it decreases. The pain is most severe when you start to walk after a rest. The nerves and capillaries adapt themselves to the situation as you walk. When you rest, the nerves and capillaries rest, also. Then, as you begin to move about again, extreme demands are made on the blood vessels and nerves, which will cause pain until they again adjust to the spur. If excessive strain has been placed on the foot the day before, the pain may also be greater. A sudden strain, as might be produced by leaping or jumping, can also increase the pain. The pain might be localized at first, but continued walking and standing will soon cause the entire heel to become tender and painful.
A heel spur is often seen on X-ray as a bony protrusion, which can vary in size. However, because a Heel Spur only indicates increased load on the plantar fascia, and not pain, an ultra sound may be required to assess other actual cause of the heel pain such and may include checking to see if the plantar fascia is inflamed or degenerated.
Non Surgical Treatment
Heel pain may be associated with a heel spur, however the heel pain is usually due to plantar fasciitis, rather than a heel spur, so treatment is usually directed at the plantar fasciitis itself. Treatment usually involves application of ice to reduce pain and inflammation, special stretching exercises, and pain-relieving or anti-inflammatory medicines. Night splints or orthotics may be recommended. It may help to avoid the activities that aggravate pain, such as long walks and running. Surgery is very rarely recommended and only after other measures fail.
Approximately 2% of people with painful heel spurs need surgery, meaning that 98 out of 100 people do well with the non-surgical treatments previously described. However, these treatments can sometimes be rather long and drawn out, and may become considerably expensive. Surgery should be considered when conservative treatment is unable to control and prevent the pain. If the pain goes away for a while, and continues to come back off and on, despite conservative treatments, surgery should be considered. If the pain really never goes away, but reaches a plateau, beyond which it does not improve despite conservative treatments, surgery should be considered. If the pain requires three or more injections of "cortisone" into the heel within a twelve month period, surgery should be considered.
