A heel spur is a bony projection on the sole (bottom) of the heel bone. This condition may accompany or result from severe cases of inflammation to the structure called plantar fascia. The plantar fascia is a fibrous band of connective tissue on the sole of the foot, extending from the heel to the toes. Heel spurs are a common foot problem resulting from excess bone growth on the heel bone. The bone growth is usually located on the underside of the heel bone, and may extend forward toward the toes. A painful tear in the plantar fascia between the toes and heel can produce a heel spur and/or inflammation of the plantar fascia. Because this condition is often correlated to a decrease in the arch of the foot, it is more prevalent after the ages of six to eight years, when the arch is fully developed.
A heel spur is caused by chronic plantar fasciitis. Your plantar fascia is a thick fibrous band of connective tissue originating on the bottom surface of the calcaneus (heel bone) and extending along the sole of the foot towards the toes.Your plantar fascia acts as a passive limitation to the over flattening of you arch. When your plantar fascia develops micro tears or becomes inflamed it is known as plantar fasciitis. When plantar fasciitis healing is delayed or injury persists, your body repairs the weak and injured soft tissue with bone. Usually your injured fascia will be healed via fibroblastic activity. They'll operate for at least six weeks. If your injury persists beyond this time, osteoblasts are recruited to the area. Osteoblasts form bone and the end result is bone (or calcification) within the plantar fascia or at the calcaneal insertion. These bone formations are known as heel spurs. This scenario is most common in the traction type injury. The additional bone growth is known as a heel spur or calcaneal spur.
Heel spurs may or may not cause symptoms. Symptoms are usually related to the plantar fasciitis. You may experience significant pain. Your heel pain may be worse in the morning when you first wake up or during certain activities.
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
Heel spurs and plantar fasciitis are treated by measures that decrease the associated inflammation and avoid reinjury. Local ice applications both reduce pain and inflammation. Physical therapy methods, including stretching exercises, are used to treat and prevent plantar fasciitis. Anti-inflammatory medications, such as ibuprofen or injections of cortisone, are often helpful. Orthotic devices or shoe inserts are used to take pressure off plantar spurs (donut-shaped insert), and heel lifts can reduce stress on the Achilles tendon to relieve painful spurs at the back of the heel. Similarly, sports running shoes with soft, cushioned soles can be helpful in reducing irritation of inflamed tissues from both plantar fasciitis and heel spurs. Infrequently, surgery is performed on chronically inflamed spurs.
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.
