A heel spur is a painful condition that is caused by the accumulation of excessive calcium under the heel of the foot. The heel bone is made up of a large structure called the calcaneus, which is connected to the bottom of the foot by durable connective tissue called fascia. If the layers of connective tissue become damaged or begin to degenerate due to wear and tear, plantar fasciitis may develop. This causes calcification, which refers to the abnormal buildup of calcium on the heel bone. As the calcium continues to accumulate, a calcified protrusion called a spur may become visible on an X-ray.
The plantar fascia is a thick, ligamentous 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. That's why tremendous stress is placed on the plantar fascia.
It is important to be aware that heel spurs may or may not cause symptoms. Symptoms are usually related to the plantar fasciitis. You may experience significant pain and it may be worse in the morning when you first wake up or during certain physical activities such as, walking, jogging, or running.
A heel spur is often seen on X-ray as a bony protrusion, which can vary in size. However, because a Heel Spur only indicates increased load on the plantar fascia, and not pain, an ultra sound may be required to assess other actual cause of the heel pain such and may include checking to see if the plantar fascia is inflamed or degenerated.
Non Surgical Treatment
The key is to identify what is causing excessive stretching of the plantar fascia. When the cause is over-pronation (flat feet), an orthotic with rearfoot posting and longitudinal arch support will help reduce the over-pronation and thus allow the condition to heal. Other common treatments for heel spurs include Stretching exercises. Losing weight. Wearing shoes that have a cushioned heel that absorbs shock. Elevating the heel with the use of a heel cradle, heel cup, or orthotics. For example, heel cradles and heel cups provide extra comfort and cushion to the heel, reducing the amount of shock and shear forces experienced from everyday activities.
Sometimes bone spurs can be surgically removed or an operation to loosen the fascia, called a plantar fascia release can be performed. This surgery is about 80 percent effective in the small group of individuals who do not have relief with conservative treatment, but symptoms may return if preventative measures (wearing proper footwear, shoe inserts, stretching, etc) are not maintained.
