A heel spur is a pointed bony outgrowth of the bone of the heel (the calcaneus bone). Heel spurs under the sole of the foot (plantar area) are associated with plantar fasciitis. Heel spurs and plantar fasciitis can occur alone or be related to underlying diseases. Heel spurs and plantar fasciitis are treated by measures that decrease the associated inflammation and avoid reinjury.
Faulty foot structures such as abnormal growths, different leg lengths, and unhealed injuries and haveinf flat feet or high arches. Muscle imbalances tight, weak or shortened muscles in your foot, plantar fascia, ankle, calf and hamstring. Over pronation can cause imbalance in foot mechanics which puts excess pressure on the plantar fascia. Poor biomechanics affect the way your foot hits the ground. If you overpronate (feet roll inward) you tend to have flat feet (pes planus), which increases stress on the heel bone. Regular shoes or high heels that are too tight or don't support your heel or arch affect the distribution of your body weight on your foot. Health conditions such as obesity, inflammatory diseases (rheumatoid arthritis, ankylosing spondylitis), bursitis, neuroma (nerve growths), gout, diabetes, Haglund's deformity, and Achilles tendinitis can also instigate the problem. Running or jogging on hard surfaces, repetative striking of the heel bone.
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 diagnosis is made when an X-ray shows a hook of bone protruding from the bottom of the foot at the point where the plantar fascia is attached to the heel bone. The plantar fascia is the thick, 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. In other words, tremendous stress is placed on the plantar fascia.
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.
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.
