The heel spur (or calcaneal spur) is a nail-like growth of calcium around the ligaments and tendons of the foot where they attach to the heel bone. The spur grows from the bone and into the flesh of the foot. A heel spur results from an anatomical change of the calcaneus (heel bone). This involves the area of the heel and occasionally, another disability, such as arthritis. The heel bone forms one end of the two longitudinal arches of the foot. These arches are held together by ligaments and are activated by the muscles of the foot (some of which are attached beneath the arches and run from the front to the back of the foot). These muscles and ligaments, like the other supporting tissues of the body, are attached in two places. Many are attached at the heel bone. The body reacts to the stress at the heel bone by calcifying the soft tissue attachments and creating a spur.
A heel spur can develop when there is an abundance of calcium creating a deposit in the calcaneus, or heel bone. Over time, this deposit grows to create an outcropping under the heel that extends into the foot. The result is a protrusion that leads to foot pain when pressure is applied, and in some cases, even during rest.
Heel spur is characterised by a sharp pain under the heel when getting out of bed in the morning or getting up after sitting for a period of time. Walking around for a while often helps reduce the pain, turning it into a dull ache. However, sports, running or walking long distance makes the condition worse. In some cases swelling around the heel maybe present.
Your doctor will review your medical history and examine your foot. X-rays are used to identify the location and size of the heel spur.
Non Surgical Treatment
Heel spurs are considered a self-limited condition, which means that by making small alterations in your lifestyle and regular routines you can often control the condition. The goal is to relieve pain, reduce friction and transfer pressure from your sensitive foot areas. By eliminating the cause of the heel spur and plantar fasciitis (i.e. better shoes, orthotics to fix your gait, losing weight) will help reduce the pressure put on your fascia and heel and can reduce the inflammation caused by your heel spur. Failure to see improvements after conservative treatments may make surgery your only option.
Surgery, which is a more radical treatment, can be a permanent correction to remove the spur itself. If your doctor believes that surgery is indicated, he will recommend an operation – but only after establishing that less drastic methods of treatment are not successful.
If you have not yet developed this condition, you can take steps to protect yourself from it. Most importantly, make it a rule to wear properly fitted footwear. Avoid shoes that have become worn down in the heel, and don’t choose shoes that cause you to walk in an abnormal fashion. Maintaining a healthy weight will ensure that undue pressure isn’t being put on the ligaments, tendons and bones of your feet. If your job requires a great deal of time on your feet, or if you exercise regularly, be sure to balance periods of activity with periods of rest for your feet.
