Overview
Heel spurs are a common foot problem resulting from excess bone growth on the heel bone. The bone growth is usually located on the underside of the heel bone, extending forward to the toes. One explanation for this excess production of bone is a painful tearing of the plantar fascia connected between the toes and heel. This can result in either a heel spur or an inflammation of the plantar fascia, medically termed plantar fascitis. Because this condition is often correlated to a decrease in the arch of the foot, it is more prevalent after the age of six to eight years, when the arch is fully developed.
Causes
Bone spurs can form anywhere in the feet in response to tight ligaments, repetitive stress injuries (typically from sports), obesity, even poorly fitting shoes. For instance, when the plantar fascia on the bottom of the foot pulls repeatedly on the heel, the ligament becomes inflamed, causing plantar fasciitis. As the bone tries to mend itself, a bone spur forms on the bottom of the heel, typically referred to as a heel spur. This is a common source of heel pain.
Symptoms
Heel spurs result in a jabbing or aching sensation on or under the heel bone. The pain is often worst when you first arise in the morning and get to your feet. You may also experience pain when standing up after prolonged periods of sitting, such as work sessions at a desk or car rides. The discomfort may lessen after you spend several minutes walking, only to return later. Heel spurs can cause intermittent or chronic pain.
Diagnosis
Your doctor will discuss your medical history and will examine your foot and heel for any deformities and inflammation (swelling, redness, heat, pain). He/she will analyze your flexibility, stability, and gait (the way you walk). Occasionally an x-ray or blood tests (to rule out diseases or infections) may be requested.
Non Surgical Treatment
If pain and other symptoms of inflammation-redness, swelling, heat-persist, you should limit normal daily activities and contact a doctor of podiatric medicine. The podiatric physician will examine the area and may perform diagnostic X-rays to rule out problems of the bone. Early treatment might involve oral or injectable anti-inflammatory medication, exercise and shoe recommendations, taping or strapping, or use of shoe inserts or orthotic devices. Taping or strapping supports the foot, placing stressed muscles and tendons in a physiologically restful state. Physical therapy may be used in conjunction with such treatments. A functional orthotic device may be prescribed for correcting biomechanical imbalance, controlling excessive pronation, and supporting of the ligaments and tendons attaching to the heel bone. It will effectively treat the majority of heel and arch pain without the need for surgery. Only a relatively few cases of heel pain require more advanced treatments or surgery. If surgery is necessary, it may involve the release of the plantar fascia, removal of a spur, removal of a bursa, or removal of a neuroma or other soft-tissue growth.
Surgical Treatment
Sometimes bone spurs can be surgically removed or an operation to loosen the fascia, called a plantar fascia release can be performed. This surgery is about 80 percent effective in the small group of individuals who do not have relief with conservative treatment, but symptoms may return if preventative measures (wearing proper footwear, shoe inserts, stretching, etc) are not maintained.
Prevention
Walk around before you buy shoes. Before you purchase your shoes, do the following. Re-lace the shoes if you’re trying on athletic shoes. Start at the farthest eyelets and apply even pressure to the laces as you come closer to the tongue of the shoe. Make sure that you can wiggle your toes freely inside of the shoe. Also, make sure that you have at enough space between your tallest toe and the end of the shoe. You should have room equal to about the width of your thumb in the tip of your shoe. Walk around to make sure that the shoe has a firm grip on your heel without sliding up and down. Walk or run a few steps to make sure your shoes are comfortable. Shoes that fit properly require no break-in period.
