A common cause of heel pain is the heel spur, a bony growth on the underside of the heel bone. The spur, visible by X-ray, appears as a protrusion that can extend forward as much as half an inch. When there is no indication of bone enlargement, the condition is sometimes referred to as "heel spur syndrome." Heel spurs result from strain on the muscles and ligaments of the foot, by stretching of the long band of tissue that connects the heel and the ball of the foot, and by repeated tearing away of the lining or membrane that covers the heel bone. These conditions may result from biomechanical imbalance, running or jogging, improperly fitted or excessively worn shoes, or obesity.
The cause of heel spurs is excessive strain placed on the plantar fascia over a long period of time, as a result of different factors. These factors include incorrect gait, being overweight, ageing or being in a job that requires a lot of standing on hard floors. It is usually a combination of any of these factors that will bring on the development of heel spurs.
Heel spurs result in a jabbing or aching sensation on or under the heel bone. The pain is often worst when you first arise in the morning and get to your feet. You may also experience pain when standing up after prolonged periods of sitting, such as work sessions at a desk or car rides. The discomfort may lessen after you spend several minutes walking, only to return later. Heel spurs can cause intermittent or chronic pain.
Heel spurs and plantar fasciitis are diagnosed based on the history of pain and tenderness localized to these areas. They are specifically identified when there is point tenderness at the bottom of the heel, which makes it difficult to walk barefoot on tile or wood floors. X-ray examination of the foot is used to identify the bony prominence (spur) of the heel bone (calcaneus).
Non Surgical Treatment
The key for the proper treatment of heel spurs is determining what is causing the excessive stretching of the plantar fascia. When the cause is over-pronation (flat feet), an orthotic with rear foot posting and longitudinal arch support is an effective device to reduce the over-pronation, and allow the condition to heal. Other common treatments include stretching exercises, losing weight, wearing shoes that have a cushioned heel that absorbs shock, and elevating the heel with the use of a heel cradle, heel cup, or orthotic. Heel cradles and heel cups provide extra comfort and cushion to the heel, and reduce the amount of shock and shear forces experienced from everyday activities.
Heel spur surgery should only be considered after less invasive treatment methods have been explored and ruled insufficient. The traditional surgical approach to treating heel spurs requires a scalpel cut to the bottom of the food which allows the surgeon to access the bone spur. Endoscopic plantar fasciotomies (EPF) involve one or two small incisions in the foot which allow the surgeon to access and operate on the bone spur endoscopically. Taking a surgical approach to heel spur treatment is a topic to explore with a foot and ankle specialist.
You can help prevent heel spur symptoms from returning by wearing the proper shoes. Customized orthotics and insoles can help relieve pressure. It is important to perform your exercises to help keep your foot stretched and relaxed.
