Heel spurs are new bone that forms in response to stress to the heel. They serve to protect the bone against the development of microfractures. Spurs start out as cartilage and progress to solid bone. They are present in about 50 percent of the population, yet not everyone has heel pain- that's the first clue that heel spurs don't always cause heel pain.
Fctors that increase the risk of developing heel spurs include a high body mass index (BMI), regular vigorous activity, and intensive training routines or sports. Factors such as these are believed to increase the incidence of repetitive stress injuries that are associated with the formation of heel spurs. When a heel spur forms, extremely sharp pain along with the feeling that a part of the heel is trying to burst through the skin usually occurs. If left untreated, an individual may eventually begin to struggle to perform simple activities such as walking.
The spur itself is not painful, however, if it is sharp and pointed it can poke into soft tissue surrounding the spur itself. As the bone spur irritates the tissue, inflammation and bruising can occur leading to heel pain. Heel spurs can affect your ability to do your usual work and/or activities, and can also trap and irritate the nerves in your heel area. They can change the way you walk, and can lead to knee, hip and low back injuries. If severe, they may require medical intervention.
Diagnosis of a heel spur can be done with an x-ray, which will be able to reveal the bony spur. Normally, it occurs where the plantar fascia connects to the heel bone. When the plantar fascia ligament is pulled excessively it begins to pull away from the heel bone. When this excessive pulling occurs, it causes the body to respond by depositing calcium in the injured area, resulting in the formation of the bone spur. The Plantar fascia ligament is a fibrous band of connective tissue running between the heel bone and the ball of the foot. This structure maintains the arch of the foot and distributes weight along the foot as we walk. However, due to the stress that this ligament must endure, it can easily become damaged which commonly occurs along with heel spurs.
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 is used a very small percentage of the time. It is usually considered after trying non-surgical treatments for at least a year. Plantar fascia release surgery is use to relax the plantar fascia. This surgery is commonly paired with tarsal tunnel release surgery. Surgery is successful for the majority of people.
Choose new shoes that are the right size. Have your foot measured when you go to the shoe store instead of taking a guess about the size. Also, try on shoes at the end of the day or after a workout, when your feet are at their largest. To ensure a good fit, wear the same type of socks or nylons that you would normally wear with the type of shoe that you are trying on.
