A heel spur also known as a calcaneal spur, is a pointed bony outgrowth of the heel bone (calcaneus). Heel spurs do not always cause pain and often are discovered incidentally on X-rays taken for other problems. Heel spurs can occur at the back of the heel and also under the heel bone on the sole of the foot, where they may be associated with the painful foot condition plantar fasciitis.
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.
Heel spurs often do not show any symptoms. If you have intermittent or chronic pain when you walk, run or jog, it may be heel spur. There will be inflammation the point where spur formation happens. The pain is caused by soft tissue injury in the heel. Patients often describe the pain as a pin or knife sticking to the heel. The pain is more specially in the morning when the patient stands up for the first time.
Diagnosis is made using a few different technologies. X-rays are often used first to ensure there is no fracture or tumor in the region. Then ultrasound is used to check the fascia itself to make sure there is no tear and check the level of scar tissue and damage. Neurosensory testing, a non-painful nerve test, can be used to make sure there is not a local nerve problem if the pain is thought to be nerve related. It is important to remember that one can have a very large heel spur and no plantar fasciitis issues or pain at all, or one can have a great deal of pain and virtually no spur at all.
Non Surgical Treatment
Over-the-counter or prescription-strength anti-inflammatory medications can help temporarily, but can cause side effects with prolonged use - the most significant being gastrointestinal upset, ulceration and bleeding. Deep tissue massage, taping and other physical therapy modalities can also be helpful. Arch support is highly recommended, either with shoe inserts or custom orthotics made by podiatrists. If pain continues, a steroid injection at the site of pain may be recommended; however, many physicians do not like injecting around the heel. The side effects of steroids injected in this area can be serious and worsen symptoms. Complications can include fat necrosis (death of fatty tissue) of the heel and rupture of the plantar fascia.
When chronic heel pain fails to respond to conservative treatment, surgical treatment may be necessary. Heel surgery can provide pain relief and restore mobility. The type of procedure used is based on examination and usually consists of releasing the excessive tightness of the plantar fascia, called a plantar fascia release. The procedure may also include removal of heel spurs.
