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.
One frequent cause of heel spurs is an abnormal motion and mal-alignment of the foot called pronation. For the foot to function properly, a certain degree of pronation is required. This motion is defined as an inward action of the foot, with dropping of the inside arch as one plants the heel and advances the weight distribution to the toes during walking. When foot pronation becomes extreme from the foot turning in and dropping beyond the normal limit, a condition known as excessive pronation creates a mechanical problem in the foot. In some cases the sole or bottom of the foot flattens and becomes unstable because of this excess pronation, especially during critical times of walking and athletic activities. The portion of the plantar fascia attached into the heel bone or calcaneous begins to stretch and pull away from the heel bone.
Heel spur and plantar fasciitis pain usually begins in the bottom of the heel, and frequently radiates into the arch. At times, however, the pain may be felt only in the arch. The pain is most intense when first standing, after any period of rest. Most people with this problem experience their greatest pain in the morning, with the first few steps after sleeping. After several minutes of walking, the pain usually becomes less intense and may disappear completely, only to return later with prolonged walking or standing. If a nerve is irritated due to the swollen plantar fascia, this pain may radiate into the ankle. In the early stages of Heel Spurs and Plantar Fasciitis, the pain will usually subside quickly with getting off of the foot and resting. As the disease progresses, it may take longer periods of time for the pain to subside.
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
Perform some exercises. Exercises that strengthen and lengthen your plantar fascia can also be very helpful for heel spurs. Try some of the following activities. Calf stretch. Place your hands on a wall. Extend 1 foot (0.3 m) behind you with your knee straight and place the other foot in front of you with the knee bent. Push your hips toward the wall and hold the stretch for 10 seconds. You should feel a pull in your calf muscles. Repeat the stretch 20 times for each foot. Plantar fascia stretch, Perform this exercise in the morning before you've done any standing or walking. Cross your injured foot over the knee of your other leg. Grasp your toes and gently pull them toward you. If you can't reach your toes, then wrap a towel around them and pull on the towel. Hold the stretch for 10 seconds and repeat 20 times for each foot.
Surgery involves releasing a part of the plantar fascia from its insertion in the heel bone, as well as removing the spur. Many times during the procedure, pinched nerves (neuromas), adding to the pain, are found and removed. Often, an inflamed sac of fluid call an accessory or adventitious bursa is found under the heel spur, and it is removed as well. Postoperative recovery is usually a slipper cast and minimal weight bearing for a period of 3-4 weeks. On some occasions, a removable short-leg walking boot is used or a below knee cast applied.
