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.
Causes of Heel Spur Syndrome are mostly due to your foot structure. Foot structure is due to hereditary for the most part, meaning it was the way you were when born. Other factors such as increase in weight, injury, improper shoes, or different activities may change the way your foot functions as well. If one leg is longer or shorter than the other, this may make your foot function improperly and be the cause of the heel spur syndrome. Improper shoes may be ones that are new or ones that are worn out and do not give good support. The higher priced shoes do not mean it's a better shoe. Pronation is a term used to describe a foot which allows the arch to fall more than normal and allows for the fascia along the bottom of the foot to put a tighter pull or a different angle of pull on the heel bone. Over time, this constant pull of the tight fascia can force the bone to enlarge and form a spur. It is not the heel spur that causes the pain directly. The spur may cause pressure against a nearby nerve causing a neuritis, or a bursa causing a bursitis.
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 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 spurs and plantar fasciitis are treated by measures that decrease the associated inflammation and avoid reinjury. Local ice applications both reduce pain and inflammation. Physical therapy methods, including stretching exercises, are used to treat and prevent plantar fasciitis. Anti-inflammatory medications, such as ibuprofen or injections of cortisone, are often helpful. Orthotic devices or shoe inserts are used to take pressure off plantar spurs (donut-shaped insert), and heel lifts can reduce stress on the Achilles tendon to relieve painful spurs at the back of the heel. Similarly, sports running shoes with soft, cushioned soles can be helpful in reducing irritation of inflamed tissues from both plantar fasciitis and heel spurs. Infrequently, surgery is performed on chronically inflamed spurs.
Almost 90% of the people suffering from heel spur get better with nonsurgical treatments. However, if the conservative treatments do not help you and you still have pain even after 9 to 12 months, your doctor may advise surgery for treating heel spur. The surgery helps in reducing the pain and improving your mobility. Some of the surgical techniques used by doctors are release of the plantar fascia. Removal of a spur. Before the surgery, the doctor will go for some pre-surgical tests and exams. After the operation, you will need to follow some specific recommendations which may include elevation of the foot, waiting time only after which you can put weight on the foot etc.
