Overview
Heel spur is a hook of bone that protrudes from the bottom of the foot where plantar fascia connects to the heel bone. Pain associated with heel spurs is usually pain from plantar fasciitis, not the actual bone. Heel spurs are most often diagnosed when a patient has visited a pain specialist or podiatrist for on-going foot pain related to plantar fasciitis; spurs are diagnosed via X-ray of the foot. Heel spurs are most commonly diagnosed in middle-aged men and women. As noted, most patients with this condition have other podiatry-related pain. This condition is a result of plantar fasciitis (when the fascia, a thick connective tissue that connects the heel bone and ball of the foot) becomes inflamed. Some 70% of plantar fasciitis patients have a bone spur. Bone spurs are soft calcium deposits caused from tension in the plantar fascia. When found on an X-ray, they are used as evidence that a patient is suffering from plantar fasciitis. Plantar fasciitis is typically caused from repetitive stress disorder. Walking, running, and dancing can cause this with time.
Causes
A heel spur is caused by chronic plantar fasciitis. Your plantar fascia is a thick fibrous band of connective tissue originating on the bottom surface of the calcaneus (heel bone) and extending along the sole of the foot towards the toes.Your plantar fascia acts as a passive limitation to the over flattening of you arch. When your plantar fascia develops micro tears or becomes inflamed it is known as plantar fasciitis. When plantar fasciitis healing is delayed or injury persists, your body repairs the weak and injured soft tissue with bone. Usually your injured fascia will be healed via fibroblastic activity. They’ll operate for at least six weeks. If your injury persists beyond this time, osteoblasts are recruited to the area. Osteoblasts form bone and the end result is bone (or calcification) within the plantar fascia or at the calcaneal insertion. These bone formations are known as heel spurs. This scenario is most common in the traction type injury. The additional bone growth is known as a heel spur or calcaneal spur.
Symptoms
You’ll typically first notice early heel spur pain under your heel in the morning or after resting. Your heel pain will be worse with the first steps and improves with activity as it warms up. When you palpate the tender area you may feel a tender bony lump. As your plantar fasciitis deteriorates and your heel spur grows, the pain will be present more often.
Diagnosis
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
Heel pain may be associated with a heel spur, however the heel pain is usually due to plantar fasciitis, rather than a heel spur, so treatment is usually directed at the plantar fasciitis itself. Treatment usually involves application of ice to reduce pain and inflammation, special stretching exercises, and pain-relieving or anti-inflammatory medicines. Night splints or orthotics may be recommended. It may help to avoid the activities that aggravate pain, such as long walks and running. Surgery is very rarely recommended and only after other measures fail.
Surgical Treatment
Most studies indicate that 95% of those afflicted with heel spurs are able to relieve their heel pain with nonsurgical treatments. If you are one of the few people whose symptoms don?t improve with other treatments, your doctor may recommend plantar fascia release surgery. Plantar fascia release involves cutting part of the plantar fascia ligament in order to release the tension and relieve the inflammation of the ligament. Sometimes the bone spur is also removed, if there is a large spur (remember that the bone spur is rarely a cause of pain. Overall, the success rate of surgical release is 70 to 90 percent in patients with heel spurs. One should always be sure to understand all the risks associated with any surgery they are considering.
Prevention
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.
