Overview
A heel spur is a hook of bone that can form on the heel bone of the foot. Heel spurs are associated with plantar fasciitis. Heel spurs can cause extreme pain in the rearfoot. The pain is most intense while standing or walking. What Causes Heel Spurs? Heel spurs develop as an abnormal growth in the heel bone due to calcium deposits that form when the plantar fascia stretches and pulls away from the heel. The plantar fascia is a ligament located at the bottom of your foot. This stretching of the plantar fascia is usually the result of flat feet or unusually high arches.
Causes
The pain caused by heel spurs can be a sharp, stabbing pain when using the foot after a long period of rest. Sometimes it then reduces to a dull throb that can worsen when engaging in activities like jogging or jumping. People sometimes describe the pain of heel spurs and plantar fasciitis as a pin sticking into the bottom of the foot when they first stand up in the morning, this pain later turns into a bearable ache. The cause of the pain is generally not the heel spur itself, but the soft-tissue buildup associated with it. People often complain that the sharp pain returns after they stand up following sitting for a prolonged period of time.
Symptoms
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.
Diagnosis
Your doctor will discuss your medical history and will examine your foot and heel for any deformities and inflammation (swelling, redness, heat, pain). He/she will analyze your flexibility, stability, and gait (the way you walk). Occasionally an x-ray or blood tests (to rule out diseases or infections) may be requested.
Non Surgical Treatment
The most important part of treatment is to rest. Do not undertake activities which hurt the foot or aggravate symptoms as will only cause painful symptoms to persist. Apply an ice pack regularly for 10 minutes at a time every hour initially to reduce pain and inflammation of the surrounding tissues. As symptoms subside frequency of application can reduce to 2 or 3 times per day. Exercises and stretches to keep the foot and ankle strong and mobile are important as long as pain allows. Stretching the plantar fascia is important, especially if symptoms are worse in the morning. A plantar fasciitis night splint is excellent for stretching and preventing the plantar fascia tightening up over night. Anti-Inflammatory medicine (e.g. ibuprofen) may be prescribed by a doctor but always check with a medical professional first as taking some medications such as ibuprofen should not be done if the patient has asthma. Shoe inserts can help to take the pressure off of the spur and reduce pain. If these treatments do not significantly ease the symptoms then surgery may be an option.
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.
