A heel spur occurs when calcium deposits build up on the underside of the heel bone, a process that usually occurs over a period of many months. Heel spurs are often caused by strains on foot muscles and ligaments, stretching of the plantar fascia, and repeated tearing of the membrane that covers the heel bone. Heel spurs are especially common among athletes whose activities include large amounts of running and jumping. Heel spurs often cause no symptoms but can be associated with intermittent pain, especially while walking, jogging, or running. Sharp pain in the heel can also be experienced when standing after sitting for a long period of time. Heel spurs can be a result of plantar fasciitis.
One frequent cause of heel spurs is an abnormal motion and mal-alignment of the foot called pronation. For the foot to function properly, a certain degree of pronation is required. This motion is defined as an inward action of the foot, with dropping of the inside arch as one plants the heel and advances the weight distribution to the toes during walking. When foot pronation becomes extreme from the foot turning in and dropping beyond the normal limit, a condition known as excessive pronation creates a mechanical problem in the foot. In some cases the sole or bottom of the foot flattens and becomes unstable because of this excess pronation, especially during critical times of walking and athletic activities. The portion of the plantar fascia attached into the heel bone or calcaneous begins to stretch and pull away from the heel bone.
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.
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
In some cases, heel spur pain may not be resolved through conservative treatment options. In those cases, cortisone injections may be used to reduce inflammation associated with the condition, helping to reduce discomfort. However, treatment options such as these must be discussed in detail with your physician, since more serious forms of treatment could yield negative side effects, such as atrophy of the heel’s fat pad, or the rupture of the plantar fascia ligament. Although such side effects are rare, they are potential problems that could deliver added heel pain.
Have surgery if no other treatments work. Before performing surgery, doctors usually give home treatments and improved footwear about a year to work. When nothing else eases the pain, here’s what you need to know about surgical options. Instep plantar fasciotomy. Doctors remove part of the plantar fascia to ease pressure on the nerves in your foot. Endoscopy. This surgery performs the same function as an instep plantar fasciotomy but uses smaller incisions so that you’ll heal faster. However, endoscopy has a higher rate of nerve damage, so consider this before you opt for this option. Be prepared to wear a below-the-knee walking cast to ease the pain of surgery and to speed the healing process. These casts, or “boots,” usually work better than crutches to speed up your recovery time.
You can help prevent heel spur symptoms from returning by wearing the proper shoes. Customized orthotics and insoles can help relieve pressure. It is important to perform your exercises to help keep your foot stretched and relaxed.
