Overview
Heel Pain is a problem for many people. It makes standing and even walking around for long periods of time very uncomfortable. Several different conditions can lead to uncomfortable heels, but the most common culprit is plantar fasciitis. This is the inflammation and swelling of the plantar fascia, a tendon that runs along the sole of your foot and attaches to the bottom of the calcaneus, or heel bone. Repeated hard impacts or strain from overuse causes micro-tears to develop in the tendon, irritating it. The minor damage compounds over time and causes the tissue to swell and tighten, painfully pulling on the heel bone.
Causes
As stated above, if biomechanical complaints such as over pronation exist during running then this can lead to planter fascitis and heel pain. Over pronation occurs when there is excessive mobility in the sab-taler joint of the foot which causes hyper mobility of the foot. Conditions such as flat feet can also cause over pronation. This increased mobility adversely affects all the muscles in the foot and can even affect the lower leg, upper leg and cause back pain. The mechanical imbalance is highlighted during running due to the increased forces being applied to the body Runners often complain that the pain increases when they enter the toe off phase of the running cycle as this stretches the muscle away from the heel bone. Apart from over pronation, other causes of planter fascitis are a change of running shoes, dramatic increases in speed work, hill work and mileage.
Symptoms
Sever?s Disease. This is a condition that occurs in 10 – 15 year old children, predominantly boys and is associated with running and repetitive jumping. It is also associated with flimsy footwear that kids may wear. It occurs when the Achilles tendon continually pulls on the apophysis of the calcaneum and does not allow for it to fuse with the body of the calcaneum. Calcaneal enthesopathy. This occurs when there is repetitive trauma at the attachment of the Achilles tendon, resulting in a spur from the calcaneum up into the Achilles tendon. It is usually visualized on x-ray and may be tender if there is an associated bursitis or tendonitis. “Pump Bump”. Also known as Haglund?s Deformity, this is a bony enlargement that exists on the back of the heel – usually related to a congenital abnormality or with chronic bursitis, causing a thickening. There may have already been trauma or pressure from footwear. Treatment is usually protection of the bump and correct footwear. Associated with a symmetrical swelling at the base of the Achilles tendon. It is usually related to repetitive trauma or inappropriate footwear. It is often red and hot in the early stages. Treatment is usually to correct the footwear, provide padding and treat the local symptoms e.g. ice, rest, physiotherapy and cortisone injection. Fat Pad Syndrome. Direct contact with the base of the heel may result in trauma to the fat pad. Related to obesity, training on hard surfaces, uneven grounds, poor shoes especially overlarge shoes which can cause shearing forces on the heel. These conditions are renowned for taking a long time to recover – usually many months.
Diagnosis
Depending on the condition, the cause of heel pain is diagnosed using a number of tests, including medical history, physical examination, including examination of joints and muscles of the foot and leg, X-rays.
Non Surgical Treatment
Treatment for plantar fasciitis should be directed at resting the plantar fascia, providing support for the arch area and limiting pronation. This is often accomplished with the use of supportive strapping with athletic tape, arch supports and orthotics. Heel lifts may also be helpful. Anti-inflammatories, pills as well as cortisone injections, may be effective as an adjunctive treatment by speeding up the reduction of inflammation. However, if used alone, anti-inflammatories rarely lead to resolution of the condition. Stretching exercises, physical therapy and night splints may also be helpful. The majority of cases respond to non-surgical treatment although it may take several weeks to reach a comfortable level. In those cases that do not respond adequately to conservative measures, surgical release of the plantar fascia may be considered. However, a new non-surgical treatment called Extracorporeal Shockwave Therapy (ESWT) is now available as an option for recalcitrant plantar fasciitis. ESWT was approved by the FDA recently for the treatment of chronic heel pain. It has been in use for several years on thousands of patients in Europe and has been successfully used to restore patients with chronic plantar fasciitis to a normal, active lifestyle. ESWT is a non-invasive procedure that uses high intensity sound waves similar to what is routinely used to treat kidney stones. The treatment is usually performed in the office or in an outpatient surgical center. The procedure is performed under local anesthesia and takes about 25 minutes. The shockwaves are directed at the plantar fascia and stimulate an inflammatory healing response.
Surgical Treatment
Surgery is a last resort in the treatment of heel pain. Physicians have developed many procedures in the last 100 years to try to cure heel pain. Most procedures that are commonly used today focus on several areas, remove the bone spur (if one is present), release the plantar fascia (plantar fasciotomy), release pressure on the small nerves in the area. Usually the procedure is done through a small incision on the inside edge of the foot, although some surgeons now perform this type of surgery using an endoscope. An endoscope is a tiny TV camera that can be inserted into a joint or under the skin to allow the surgeon to see the structures involved in the surgery. By using the endoscope, a surgeon can complete the surgery with a smaller incision and presumably less damage to normal tissues. It is unclear whether an endoscopic procedure for this condition is better than the traditional small incision. Surgery usually involves identifying the area where the plantar fascia attaches to the heel and releasing the fascia partially from the bone. If a small spur is present this is removed. The small nerves that travel under the plantar fascia are identified and released from anything that seems to be causing pressure on the nerves. This surgery can usually be done on an outpatient basis. This means you can leave the hospital the same day.
Prevention
Maintaining flexible and strong muscles in your calves, ankles, and feet can help prevent some types of heel pain. Always stretch and warm-up before exercising. Wear comfortable, properly fitting shoes with good arch support and cushioning. Make sure there is enough room for your toes.
