What Causes Inferior Calcaneal Spur
Overview
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.
Causes
Heel spurs can form as a result of repeated strain placed on foot muscles and ligaments as well as from abnormally stretching the band of tissue connecting the heel and ball of the foot. Repeated injury to the membrane that lines the heel bone can also cause problems as can repeated tight pressure on the back of the heel. The causes can range from excessive walking (especially if unaccustomed to walking), running or jumping to improperly fitted or worn-out shoes. Runners, volleyball players, and tennis players, people who do step aerobics or stair climbing for exercise, those with flat feet, pregnant women, the obese and diabetics and those who wear tight-fitting shoes with a high heel are all prone to developing spurs (and plantar fasciitis) more readily.
Symptoms
Heel spurs often do not show any symptoms. If you have intermittent or chronic pain when you walk, run or jog, it may be heel spur. There will be inflammation the point where spur formation happens. The pain is caused by soft tissue injury in the heel. Patients often describe the pain as a pin or knife sticking to the heel. The pain is more specially in the morning when the patient stands up for the first time.
Diagnosis
Heel spurs and plantar fasciitis are diagnosed based on the history of pain and tenderness localized to these areas. They are specifically identified when there is point tenderness at the bottom of the heel, which makes it difficult to walk barefoot on tile or wood floors. X-ray examination of the foot is used to identify the bony prominence (spur) of the heel bone (calcaneus).
Non Surgical Treatment
The key is to identify what is causing excessive stretching of the plantar fascia. When the cause is over-pronation (flat feet), an orthotic with rearfoot posting and longitudinal arch support will help reduce the over-pronation and thus allow the condition to heal. Other common treatments for heel spurs include Stretching exercises. Losing weight. Wearing shoes that have a cushioned heel that absorbs shock. Elevating the heel with the use of a heel cradle, heel cup, or orthotics. For example, heel cradles and heel cups provide extra comfort and cushion to the heel, reducing the amount of shock and shear forces experienced from everyday activities.
Surgical Treatment
More than 90 percent of people get better with nonsurgical treatments. If conservative treatment fails to treat symptoms of heel spurs after a period of 9 to 12 months, surgery may be necessary to relieve pain and restore mobility. Surgical techniques include release of the plantar fascia, removal of a spur. Pre-surgical tests or exams are required to identify optimal candidates, and it's important to observe post-surgical recommendations concerning rest, ice, compression, elevation of the foot, and when to place weight on the operated foot. In some cases, it may be necessary for patients to use bandages, splints, casts, surgical shoes, crutches, or canes after surgery. Possible complications of heel surgery include nerve pain, recurrent heel pain, permanent numbness of the area, infection, and scarring. In addition, with plantar fascia release, there is risk of instability, foot cramps, stress fracture, and tendinitis.
Prevention
Use orthotic inserts. You can purchase orthotics over the counter, or you can have orthotics specially fitted by your podiatrist. Try 1 of these options. Heel cups. These inserts will help to align the bones in your foot and to cushion your heel. Check your skin for blisters when you first start using heel cups. Also, your feet may sweat more with a heel cup, so change your socks and shoes often. Insoles. While you can pick up generic insoles at a drugstore, you may have more luck if you go to a store that sells athletic shoes. Push on the arch to make sure that it doesn't collapse. If your insoles help but could use a little work, you can take them to a podiatrist to get them customized. Custom orthotics. A podiatrist can make a cast of your foot and provide you with custom-made orthotics. These may be more expensive, but they are made of materials specifically designed for your needs, and they can last up to 5 years if your podiatrist refurbishes them every 1 or 2 years. To find a podiatrist near you, look at the Web page for the American Academy of Podiatric Sports Medicine. Dynamic Insoles. Lack of elasticity in plantar fascia in the foot is for most people the real problem. If there is poor elasticity in the lengthwise tendons in the foot (plantar fascia) in relation to a person's general condition, only a small additional strain is required for the pull on the tendons to cause damage to the tissues connecting the tendons to the heel bone. This will generate an inflamed condition called Plantar Fasciitis.
