Overview
A heel spur is a calcium deposit on the underside of the heel bone, often caused by strain on foot muscles and ligaments. Heel spurs are common among athletes but also tend to develop as we age, as flexibility decreases. Heel spurs can be painful when associated with plantar fasciitis, an inflammation of the connective tissue that runs along the bottom of the foot and connects the heel bone to the ball of the foot.
If left untreated, the mild aches associated with this condition can evolve into chronic pain. And as you try to compensate for the pain, your gait may change, which could impact your knee, hip and back.
Causes
A heel spur is a bony overgrowth on the bottom of your heel bone. The heel spur is usually a result of an inflamed ligament (plantar fascia) on the bottom of the foot that attaches to the heel bone. Constant abnormal pulling of this ligament irritates the heel bone and the body lays down a bone spur as a protective mechanism. The patient usually complains of pain with the first step in the morning, some relief following activity, but returning after extended amounts of time standing or walking.
Symptoms
You may or may not experience any symptoms with your heel spurs. It is normally the irritation and inflammation felt in the tissues around your heel spur that cause discomfort. Heel pain is one of the first things you may notice, especially when pushing off the ball of your foot (stretches the plantar fascia). The pain can get worse over time and tends to be stronger in the morning, subsiding throughout the day; although it does return with increased activity. A sharp, poking pain in your heel that feels like you're stepping on a stone can often be felt while standing or walking. You will sometimes be able to feel a bump on the bottom of your heel, and occasionally bruising may appear.
Diagnosis
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 fascitis are usually controlled with conservative treatment. Early intervention includes stretching the calf muscles while avoiding re-injuring the plantar fascia. Decreasing or changing activities, losing excess weight, and improving the proper fitting of shoes are all important measures to decrease this common source of foot pain. Modification of footwear includes shoes with a raised heel and better arch support. Shoe orthotics recommended by a healthcare professional are often very helpful in conjunction with exercises to increase strength of the foot muscles and arch. The orthotic prevents excess pronation and lengthening of the plantar fascia and continued tearing of this structure. To aid in this reduction of inflammation, applying ice for 10-15 minutes after activities and use of anti-inflammatory medication can be helpful. Physical therapy can be beneficial with the use of heat modalities, such as ultrasound that creates a deep heat and reduces inflammation. If the pain caused by inflammation is constant, keeping the foot raised above the heart and/or compressed by wrapping with an ace bandage will help. Corticosteroid injections are also frequently used to reduce pain and inflammation. Taping can help speed the healing process by protecting the fascia from reinjury, especially during stretching and walking.
Surgical Treatment
Usually, heel spurs are curable with conservative treatment. If not, heel spurs are curable with surgery, although there is the possibility of them growing back. About 10% of those who continue to see a physician for plantar fascitis have it for more than a year. If there is limited success after approximately one year of conservative treatment, patients are often advised to have surgery.
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.
