A heel spur is a bony growth at the underside of the heel bone. The underlying cause of heel spurs is a common condition called ?Plantar Fasciitis?. This is Latin for inflammation of the plantar fascia. This tendon forms the arch of the foot, starting at the heel and running to the ball of the foot. Plantar Fasciitis is a persistent and painful condition. Interestingly, in some people a heel spur has been present for a long time, but no pain is felt for years until one day the pain suddenly appears ?out of nothing?.
Heel spurs can form as a result of repeated strain placed on foot muscles and ligaments as well as from abnormally stretching the band of tissue connecting the heel and ball of the foot. Repeated injury to the membrane that lines the heel bone can also cause problems as can repeated tight pressure on the back of the heel. The causes can range from excessive walking (especially if unaccustomed to walking), running or jumping to improperly fitted or worn-out shoes. Runners, volleyball players, and tennis players, people who do step aerobics or stair climbing for exercise, those with flat feet, pregnant women, the obese and diabetics and those who wear tight-fitting shoes with a high heel are all prone to developing spurs (and plantar fasciitis) more readily.
An individual with the lower legs turning inward, a condition called genu valgus or "knock knees," can have a tendency toward excessive pronation. This can lead to a fallen arch and problems with the plantar fascia and heel spurs. Women tend to suffer from this condition more than men. Heel spurs can also result from an abnormally high arch. Other factors leading to heel spurs include a sudden increase in daily activities, an increase in weight, or a thinner cushion on the bottom of the heel due to old age. A significant increase in training intensity or duration may cause inflammation of the plantar fascia. High-heeled shoes, improperly fitted shoes, and shoes that are too flexible in the middle of the arch or bend before the toe joints will cause problems with the plantar fascia and possibly lead to heel spurs.
Because the diagnosis of heel spurs can be confused with tarsal tunnel syndrome (as described earlier), most surgeons advocate performing a tarsal tunnel release (or at least a partial tarsal tunnel release) along with the plantar fascia release. This surgery is about 80percent successful in relieving pain in the small group of patients who do not improve with conservative treatments.
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 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.
Use orthotic inserts. You can purchase orthotics over the counter, or you can have orthotics specially fitted by your podiatrist. Try 1 of these options. Heel cups. These inserts will help to align the bones in your foot and to cushion your heel. Check your skin for blisters when you first start using heel cups. Also, your feet may sweat more with a heel cup, so change your socks and shoes often. Insoles. While you can pick up generic insoles at a drugstore, you may have more luck if you go to a store that sells athletic shoes. Push on the arch to make sure that it doesn't collapse. If your insoles help but could use a little work, you can take them to a podiatrist to get them customized. Custom orthotics. A podiatrist can make a cast of your foot and provide you with custom-made orthotics. These may be more expensive, but they are made of materials specifically designed for your needs, and they can last up to 5 years if your podiatrist refurbishes them every 1 or 2 years. To find a podiatrist near you, look at the Web page for the American Academy of Podiatric Sports Medicine. Dynamic Insoles. Lack of elasticity in plantar fascia in the foot is for most people the real problem. If there is poor elasticity in the lengthwise tendons in the foot (plantar fascia) in relation to a person's general condition, only a small additional strain is required for the pull on the tendons to cause damage to the tissues connecting the tendons to the heel bone. This will generate an inflamed condition called Plantar Fasciitis.
