Overview
The calcaneus is the largest bone in the foot. Pain in the heel region can sometimes be related to Plantar Fasciitis, inflammation of the plantar fascia ligament in the heel area. A heel spur is a hook of bone that forms on the calcaneus where the plantar fascia attaches. Heel spurs can be identified with an X-ray. A heel spur can occur with or without Plantar Fasciitis.
Causes
A bone spur forms as the body tries to repair itself by building extra bone. It generally forms in response to pressure, rubbing, or stress that continues over a long period of time. Some bone spurs form as part of the aging process. As we age, the slippery tissue called cartilage that covers the ends of the bones within joints breaks down and eventually wears away (osteoarthritis). Bone spurs due to aging are especially common in the joints of the spine and feet.
Symptoms
Pain and discomfort associated with heel spurs does not occur from the spur itself. The bone growth itself has no feeling. However, as you move, this growth digs into sensitive nerves and tissue along the heel of the foot, resulting in severe pain. Pain can also be generated when pushing off with the toes while walking. Swelling along the heel is also common.
Diagnosis
Diagnosis of a heel spur can be done with an x-ray, which will be able to reveal the bony spur. Normally, it occurs where the plantar fascia connects to the heel bone. When the plantar fascia ligament is pulled excessively it begins to pull away from the heel bone. When this excessive pulling occurs, it causes the body to respond by depositing calcium in the injured area, resulting in the formation of the bone spur. The Plantar fascia ligament is a fibrous band of connective tissue running between the heel bone and the ball of the foot. This structure maintains the arch of the foot and distributes weight along the foot as we walk. However, due to the stress that this ligament must endure, it can easily become damaged which commonly occurs along with heel spurs.
Non Surgical Treatment
There are many temporary solutions to resolve the pain associated with irritation to the plantar ligaments. Common recommendations are ice and anti-inflammatory medications or even cortisone injections, however none of these solve the fundamental problem. To permanently resolve heel spurs you need to support and restrict the movement of the plantar ligaments. Flexible shoes will aggravate and often contribute to heel spurs. We recommend a RIGID orthotic that extends from the metatarsal heads to the heel to resolve heel spurs.
Surgical Treatment
Surgery to correct for heel spur syndrome is a common procedure which releases plantar fascia partially from its attachment to the calcaneous (heel bone). This part of the surgery is called a plantar fasciotomy due to the fact the fascia is cut. This is most often done through an open procedure as any heel spur or bursa can be removed at the same time. If the spur is not removed during the surgery, it will probably be just as successful, as the large spur is not the true problem. Some physicians use an endoscopic approach (EPF) where a small camera aids the physician during surgery with typically smaller incisions on each side of your foot.
Prevention
In order to prevent heel spurs, it?s important that you pay attention to the physical activities you engage in. Running or jogging on hard surfaces, such as cement or blacktop, is typical for competitive runners, but doing this for too long without breaks can lead to heel spurs and foot pain. Likewise, the shoes you wear can make a big difference in whether or not you develop heel spurs. Have your shoes and feet checked regularly by our Dallas podiatrist to ensure that you are wearing the proper equipment for the activities. Regular checkups with a foot and ankle specialist can help avoid the development of heel spurs.
