Bone spurs are bony projections that develop along the edges of bones. Bone spurs (osteophytes) often form where bones meet each other - in your joints. They can also form on the bones of your spine. The main cause of bone spurs is the joint damage associated with osteoarthritis. Most bone spurs cause no symptoms and may go undetected for years. They may not require treatment. Decisions about treatment depend on where spurs are situated and how they affect your health.
Heel spurs are exacerbated by an movements that stretch, twist or impact the plantar ligaments. Running, jumping, standing or walking on hard surfaces with unsupportive shoes, walking barefoot in sand are all activities that can activate heel spurs and plantar fasciitis. Obesity is another factor that increases stress to the plantar ligaments.
Most people think that a bone "spur" is sharp and produces pain by pressing on tissue, when in fact, these bony growths are usually smooth and flat. Although they rarely cause pain on their own, bone spurs in the feet can lead to callus formation as tissue builds up to provide added cushion over the area of stress. Over time, wear and tear on joints may cause these spurs to compress neighboring ligaments, tendons or nerves, thus injuring tissue and causing swelling, pain and tearing.
A Heel Spur diagnosis is made when an X-ray shows a hook of bone protruding from the bottom of the foot at the point where the plantar fascia is attached to the heel bone. The plantar fascia is the thick, connective tissue that runs from the calcaneus (heel bone) to the ball of the foot. This strong and tight tissue helps maintain the arch of the foot. It is also one of the major transmitters of weight across the foot as you walk or run. In other words, tremendous stress is placed on the plantar fascia.
Non Surgical Treatment
The majority of heel spurs are treated with non-surgical interventions. These can relieve pain, but may take from about 3 months to up to a year for symptoms to resolve. Rest, icing, and over-the-counter anti-inflammatory or prescription medications can help ease symptoms. Cortisone injections may also be used. Physical therapists may instruct you to perform stretching exercises to help relax the tissues in the heel. Your doctor may recommend custom orthotics or shoe inserts to position and cushion your heel. Night splints can help position the heel and arch of the foot while you sleep. Some doctors may recommend extracorporeal shock wave therapy (ESWT). This treatment uses energy pulses to start the repair process in the heel tissues. ESWT is recommend when other non-surgical treatments have failed.
When chronic heel pain fails to respond to conservative treatment, surgical treatment may be necessary. Heel surgery can provide relief of pain and restore mobility. The type of procedure used is based on examination and usually consists of releasing the excessive tightness of the plantar fascia, called a plantar fascia release. Depending on the presence of excess bony build up, the procedure may or may not include removal of heel spurs. Similar to other surgical interventions, there are various modifications and surgical enhancements regarding surgery of the heel.
Prevention of heel spur syndrome may be best by finding a good supportive shoe. Never go barefoot or wear a flat soled shoe. There are many over the counter arch supports that give increased support for your feet. Usually when there is excessive pronation the Achilles Tendon contracts or becomes shortened over time since it is not being used fully. The shortened Achilles Tendon is called an equinus deformity. By keeping this tendon stretched it may decrease some of the tension in the foot. Some theories believe the Achilles Tendon and plantar fascia is continuous. Before you get up from rest, stretch out your Achilles and the plantar fascia. You may attempt to spell the alphabet with your foot and ankle, use a towel against pressure on your foot, or roll a can of soup or sodapop on the ground. Ice may work well at the times of severe pain. For a chronic pain, or longer lasting pain heat therapy may improve the condition.
