Heel spurs are small lumps of excess bone that grow and stick out on the calcaneus, aka heel bone. They usually develop in response to friction, tightness, inflammation or injury when the body lays down extra layers of bone to try and protect itself. There are two areas where heel bone spurs tend to develop. At the back of the heel: these are usually due to conditions such as Achilles tendonitis, tight calf muscles or wearing tight footwear. These are known as posterior calcaneal spurs. Underneath the heel: these are usually due to conditions such as plantar fasciitis, muscle imbalance or altered foot biomechanics. These are known as inferior calcaneal spurs.
Bone spurs can occur all over the body including the spine, shoulders, hands, hips and feet. The feet are a common place to find them. A heel spur happens when the body tries to mend itself. Building extra bone is one way your body tries to correct a weakness. Wearing shoes that are too tight in the heel can cause bone spurs. More women than men get heel spurs because of the kinds of shoes they wear. Athletes who stress their feet and legs routinely are also prone to heel spurs. Being overweight can also indirectly cause heel spurs by over-exerting the plantar fascia. Some heel spurs are caused by the aging process, in which the cartilage covering the ends of bones wears away. This process can lead to pain, swelling and spur formation. Stress-related problems with the plantar fascia frequently lead to heel spurs.
Most of the time heel spurs present as pain in the region surrounding the spur, which typically increases in intensity after prolonged periods of rest. Patients may not be able to bear weight on the afflicted heel comfortably. Running, walking, or lifting heavy weight may exacerbate the issue.
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
Heel spurs can be treated by wearing orthotic insoles inside the shoe. Orthotics are designed to correct incorrect gait, in particular over-pronation (rolling in of the foot and collapsing of the arches). Over-pronation is a very common foot condition, affecting at least half of the population. It is a major contributing cause of heel spurs. Orthotics are very effective in that the device corrects the foot to its natural position. By supporting the arches properly and preventing excess rolling in of the foot, the plantar fascia is placed under much less strain and stress compared to an unsupported foot. Less strain on the ligament means less pulling away from the heel bone, allowing the inflammation to heal faster. In addition to orthotic treatment, most podiatrists and physiotherapists recommend a series of exercises to help make the ligaments in the feet and legs longer and more flexible. In turn this will help reduce strain on the plantar fascia.
Surgery to correct for heel spur syndrome is a common procedure which releases plantar fascia partially from its attachment to the calcaneous (heel bone). This part of the surgery is called a plantar fasciotomy due to the fact the fascia is cut. This is most often done through an open procedure as any heel spur or bursa can be removed at the same time. If the spur is not removed during the surgery, it will probably be just as successful, as the large spur is not the true problem. Some physicians use an endoscopic approach (EPF) where a small camera aids the physician during surgery with typically smaller incisions on each side of your foot.
