When the body is under stress or constent inflammation it will deposit calcium to our bones. This added ‘bone growth’ is designed to relieve the added stress/pressure to our connective tissue. In the case of a heel spur, added calcium to the heel bone (calcaneus). It usually forms at the bottom underside of the heel bone where the plantar fascia attaches. This calcium deposit forms over a period of many months. Heel bones can very in shape and size from person to person. An irregular shape heel (calcaneus) can cause the tissue to twist (plantar ligament and Achilles tendon) or a smaller heel bone will put additional stress on tendons and ligaments.
Everyone can be affected by heel spurs, however, certain groups of people have an increased risk. For example, Plantar Fasciitis is a common running injury. People who walk a lot are much more likely to have heel spurs or people who play golf or play tennis. Over-weight people are also more at risk for heel bone spurs as our feet are not designed to carry around extra weight. As a result the ligaments under the foot are placed under constant stress, which inevitably will lead to foot problems.
Major symptoms consist of pain in the region surrounding the spur, which typically increases in intensity after prolonged periods of rest. Patients may report heel pain to be more severe when waking up in the morning. Patients may not be able to bear weight on the afflicted heel comfortably. Running, walking, or lifting heavy weight may exacerbate the issue.
A thorough history and physical exam is always necessary for the proper diagnosis of heel spurs and other foot conditions. X rays of the heel area are helpful, as excess bone production will be visible.
Non Surgical Treatment
Podiatric Care for heel spur syndrome may involve keeping the fascia stretched out by performing exercises. Your doctor may also suggest for you to be seen by a physical therapist. You probably will be advised on the best shoes to wear or some inserts for your shoes. Your podiatrist may suggest that a custom made orthotic be made to allow your foot to function in the most ideal way especially if you have excessive pronation. A heel lift may be used if you have a leg length discrepancy. Medical treatment may include anti-inflammatory oral medications or an injection of medication and local anesthetic to reduce the swelling and decrease pain. If a bursitis is present the medication may greatly improve the symptoms. Your podiatric physician may also recommend a surgical procedure to actually fix the structural problem of your foot.
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.
