A bone spur (osteophyte) is a bony growth that forms along the edge of normal bone in response to wear and tear, most frequently in the joints. A heel spur is a bone spur of the heel bone, which causes heel pain by rubbing on the achilles tendon or other soft tissues.
Heel Spurs develop when the plantar fascia is excessively and repetitively pulled away from the heel bone. In many cases, a heel spur can develop along with plantar fasciitis, but can also occur by itself. Heel spurs often develop in middle-aged patients, but can also occur in younger people as well. Athletes are especially prone to heel spur due to the regular stress on their heels.
With heel spurs, people often talk about a dull ache which is felt most of the time with episodes of a sharp pain in the center of the heel or on the inside margin of the heel. Often the pain is worse on first rising in the morning and after rest and is aggravated by prolonged weight bearing and thin-soled shoes.
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
There are various ways to treat heel spurs. The first is to rest and apply ice to the afflicted area. Shoe inserts and night splints can also treat plantar fasciitis, and in turn, heels spurs. Unless you have stomach sensitivities, you may want to consider taking over-the-counter anti-inflammatory medication such as naprosyn to lower the swelling. A physical therapist can recommend gentle exercises and stretches to relax the tissue around the heel bone to relieve the tension. Even with these treatments, a stubborn heel spur may not go away. A physical therapist may decide to inject cortisone into the area to decrease inflammation, but that can cause other problems such as plantar fascial rupture and fat pad atrophy. Extracorporeal shock wave therapy is also an option, which uses energy pulses to apply microtrauma around the heel spur. Surgery is also an option but is not suggested unless the heel spur lasts more than a year. To prevent heel spurs from returning, shoe inserts can relieve the pressure on the plantar fascia. Also continue the recommended stretches and exercises.
Surgery involves releasing a part of the plantar fascia from its insertion in the heel bone, as well as removing the spur. Many times during the procedure, pinched nerves (neuromas), adding to the pain, are found and removed. Often, an inflamed sac of fluid call an accessory or adventitious bursa is found under the heel spur, and it is removed as well. Postoperative recovery is usually a slipper cast and minimal weight bearing for a period of 3-4 weeks. On some occasions, a removable short-leg walking boot is used or a below knee cast applied.
To prevent this condition, wearing properly fitted shoes with good arch support is very important. If a person is overweight, weight loss can help diminish stress on the feet and help prevent foot problems. For those who exercise frequently and intensely, proper stretching is always necessary, especially when there is an increase in activities or a change in running technique. It is not recommended to attempt to work through the pain, as this can change a mild case of heel spurs and plantar fascitis into a long-lasting and painful episode of the condition.
