Bone spurs are bony projections that develop along the edges of bones. Bone spurs (osteophytes) often form where bones meet each other - in your joints. They can also form on the bones of your spine. The main cause of bone spurs is the joint damage associated with osteoarthritis. Most bone spurs cause no symptoms and may go undetected for years. They may not require treatment. Decisions about treatment depend on where spurs are situated and how they affect your health.
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.
Pain and discomfort associated with heel spurs does not occur from the spur itself. The bone growth itself has no feeling. However, as you move, this growth digs into sensitive nerves and tissue along the heel of the foot, resulting in severe pain. Pain can also be generated when pushing off with the toes while walking. Swelling along the heel is also common.
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
The majority of heel spurs are treated with non-surgical interventions. These can relieve pain, but may take from about 3 months to up to a year for symptoms to resolve. Rest, icing, and over-the-counter anti-inflammatory or prescription medications can help ease symptoms. Cortisone injections may also be used. Physical therapists may instruct you to perform stretching exercises to help relax the tissues in the heel. Your doctor may recommend custom orthotics or shoe inserts to position and cushion your heel. Night splints can help position the heel and arch of the foot while you sleep. Some doctors may recommend extracorporeal shock wave therapy (ESWT). This treatment uses energy pulses to start the repair process in the heel tissues. ESWT is recommend when other non-surgical treatments have failed.
Surgery is used a very small percentage of the time. It is usually considered after trying non-surgical treatments for at least a year. Plantar fascia release surgery is use to relax the plantar fascia. This surgery is commonly paired with tarsal tunnel release surgery. Surgery is successful for the majority of people.
A variety of steps can be taken to avoid heel pain and accompanying afflictions. Wear shoes that fit well-front, back, and sides-and have shock-absorbent soles, rigid shanks, and supportive heel counters. Wear the proper shoes for each activity. Do not wear shoes with excessive wear on heels or soles. Prepare properly before exercising. Warm up and do stretching exercises before and after running. Pace yourself when you participate in athletic activities. Don't underestimate your body's need for rest and good nutrition. If obese, lose weight.
