The heel bone is the largest bone in the foot and absorbs the most shock and pressure. A heel spur develops as an abnormal growth of the heel bone. Most commonly, calcium deposits form when the plantar fascia pulls away from the heel area, causing a bony protrusion, or heel spur to develop. While bone spurs can develop in other locations such as the rear of the heel bone, this is the most common location for development. The plantar fascia is a broad band of fibrous tissue located along the bottom surface of the foot that runs from the heel to the forefoot. Heel spurs can cause extreme pain in the rearfoot, especially while standing or walking.
The plantar fascia is a thick, ligamentous connective tissue that runs from the calcaneus (heel bone) to the ball of the foot. This strong and tight tissue helps maintain the arch of the foot. It is also one of the major transmitters of weight across the foot as you walk or run. That’s why tremendous stress is placed on the plantar fascia.
Although it may take years to become a problem, once it appears, it may cause considerable suffering. Because of proximity to the tendons, the spur is a source of continuous painful aching. The sensation has been described as “a toothache in the foot.” When you place your weight on the heel, the pain can be sufficient to immobilize you.
Sharp pain localized to the heel may be all a doctor needs to understand in order to diagnose the presence of heel spurs. However, you may also be sent to a radiologist for X-rays to confirm the presence of heel spurs.
Non Surgical Treatment
The key for the proper treatment of heel spurs is determining what is causing the excessive stretching of the plantar fascia. When the cause is over-pronation (flat feet), an orthotic with rearfoot posting and longitudinal arch support is an effective device to reduce the over-pronation, and allow the condition to heal. Other common treatments include stretching exercises, losing weight, wearing shoes that have a cushioned heel that absorbs shock, and elevating the heel with the use of a heel cradle, heel cup, or orthotic. Heel cradles and heel cups provide extra comfort and cushion to the heel, and reduce the amount of shock and shear forces experienced from everyday activities.
Surgery involves releasing a part of the plantar fascia from its insertion in the heel bone, as well as removing the spur. Many times during the procedure, pinched nerves (neuromas), adding to the pain, are found and removed. Often, an inflamed sac of fluid call an accessory or adventitious bursa is found under the heel spur, and it is removed as well. Postoperative recovery is usually a slipper cast and minimal weight bearing for a period of 3-4 weeks. On some occasions, a removable short-leg walking boot is used or a below knee cast applied.
A heel spur occurs when calcium deposits build up on the underside of the heel bone. The abnormal calcium deposits form when the plantar fascia pulls away from the heel. This stretching of the plantar fascia is common among people who have flat feet, but people with unusually high arches can also develop this problem. Heel spurs are especially common among athletes who do a lot of running and jumping. Also, women who wear high heels have a significantly higher incidence of heel spurs. Still, it can happen to anyone.
Heel spurs under the sole of the foot (plantar area) are associated with inflammation of the plantar fascia (fasciitis), the “bowstring-like” tissue stretching underneath the sole that attaches at the heel. Plantar heel spurs cause localized tenderness and pain made worse when stepping down on the heel. Heel spurs and plantar fasciitis can occur alone or be related to underlying diseases that cause arthritis (inflammation of the joints), such as reactive arthritis (formerly called Reiter’s disease), ankylosing spondylitis, and diffuse idiopathic skeletal hyperostosis. It is important to note that heel spurs may cause no symptoms at all and may be incidentally discovered during X-ray exams taken for other purposes.
Heel spurs often cause no symptoms. But heel spurs can be associated with intermittent or chronic pain, especially while walking, jogging, or running, if inflammation develops at the point of the spur formation. In general, the cause of the pain is not the heel spur itself but the soft-tissue injury associated with it. Many people describe the pain of heel spurs and plantar fasciitis as a knife or pin sticking into the bottom of their feet when they first stand up in the morning, a pain that later turns into a dull ache. They often complain that the sharp pain returns after they stand up after sitting for a prolonged period of time.
Your doctor, when diagnosing and treating this condition will need an x-ray and sometimes a gait analysis to ascertain the exact cause of this condition. If you have pain in the bottom of your foot and you do not have diabetes or a vascular problem, some of the over-the-counter anti-inflammatory products such as Advil or Ibuprofin are helpful in eradicating the pain. Pain creams, such as Neuro-eze, BioFreeze & Boswella Cream can help to relieve pain and help increase circulation.
Non Surgical Treatment
Perform some exercises. Exercises that strengthen and lengthen your plantar fascia can also be very helpful for heel spurs. Try some of the following activities. Calf stretch. Place your hands on a wall. Extend 1 foot (0.3 m) behind you with your knee straight and place the other foot in front of you with the knee bent. Push your hips toward the wall and hold the stretch for 10 seconds. You should feel a pull in your calf muscles. Repeat the stretch 20 times for each foot. Plantar fascia stretch, Perform this exercise in the morning before you’ve done any standing or walking. Cross your injured foot over the knee of your other leg. Grasp your toes and gently pull them toward you. If you can’t reach your toes, then wrap a towel around them and pull on the towel. Hold the stretch for 10 seconds and repeat 20 times for each foot.
In a small number of cases (usually less than 5 percent), patients may not experience relief after trying the recommendations listed above. It is important that conservative treatments (such as those listed above) be performed for AT LEAST a year before considering surgery. Time is important in curing the pain from heel spurs, and insufficient treatment before surgery may subject you to potential complications from the procedure. If these treatments fail, your doctor may consider an operation to loosen the plantar fascia, called a plantar fascia release.
There are heel spur prevention methods available in order to prevent the formation of a heel spur. First, proper footwear is imperative. Old shoes or those that do not fit properly fail to absorb pressure and provide the necessary support. Shoes should provide ample cushioning through the heel and the ball of the foot, while also supporting the arch. Wearing an orthotic shoe insert is one of the best ways to stretch the plantar fascia and prevent conditions such as heel spurs. Stretching the foot and calf is also helpful in preventing damage. Athletes in particular should make sure to stretch prior to any physical activity. Stretching helps prevent heel spurs by making tissue stronger as well as more flexible. In addition, easing into a new or increasingly difficult routine should be done to help avoid strain on the heel and surrounding tissue.
