Plantar fasciitis is a painful inflammation of the plantar fascia, a fibrous band of tissue on the bottom of the foot that helps to support the arch. Plantar fasciitis occurs when this band of tissue is overloaded or overstretched. This causes small tears in the fibers of the fascia, especially where the fascia meets the heel bone. Plantar fasciitis is common in obese people and in pregnant women, perhaps because their extra body weight overloads the delicate plantar fascia. It is also more common in people with diabetes, although the exact reason for this is unknown. Plantar fasciitis also can be triggered by physical activities that overstretch the fascia, including sports (volleyball, running, tennis), other exercises (step aerobics, stair climbing) or household exertion (pushing furniture or a large appliance). In athletes, plantar fasciitis may follow intense training, especially in runners who push themselves too quickly to run longer distances. Worn or poorly constructed shoes can contribute to the problem if they do not provide enough arch support, heel cushion or sole flexibility.
Excessive stretching of the plantar fascia can result in microtrauma of this structure either along its course or where it inserts onto the medial calcaneal tuberosity. This microtrauma, if repetitive, can result in chronic degeneration of the plantar fascia fibers. The loading of the degenerative and healing tissue at the plantar fascia may cause significant plantar pain, particularly with the first few steps after sleep or other periods of inactivity. The term fasciitis may, in fact, be something of a misnomer, because the disease is actually a degenerative process that occurs with or without inflammatory changes, which may include fibroblastic proliferation. This has been proven from biopsies of fascia from people undergoing surgery for plantar fascia release.
Among the symptoms for Plantar Fasciitis is pain usually felt on the underside of the heel, often most intense with the first steps after getting out of bed in the morning. It is commonly associated with long periods of weight bearing or sudden changes in weight bearing or activity. Plantar Fasciitis also called “policeman’s heel” is presented by a sharp stabbing pain at the bottom or front of the heel bone. In most cases, heel pain is more severe following periods of inactivity when getting up and then subsides, turning into a dull ache.
Plantar fasciitis is usually diagnosed by a health care provider after consideration of a person’s presenting history, risk factors, and clinical examination. Tenderness to palpation along the inner aspect of the heel bone on the sole of the foot may be elicited during the physical examination. The foot may have limited dorsiflexion due to tightness of the calf muscles or the Achilles tendon. Dorsiflexion of the foot may elicit the pain due to stretching of the plantar fascia with this motion. Diagnostic imaging studies are not usually needed to diagnose plantar fasciitis. However, in certain cases a physician may decide imaging studies (such as X-rays, diagnostic ultrasound or MRI) are warranted to rule out other serious causes of foot pain. Bilateral heel pain or heel pain in the context of a systemic illness may indicate a need for a more in-depth diagnostic investigation. Lateral view x-rays of the ankle are the recommended first-line imaging modality to assess for other causes of heel pain such as stress fractures or bone spur development. Plantar fascia aponeurosis thickening at the heel greater than 5 millimeters as demonstrated by ultrasound is consistent with a diagnosis of plantar fasciitis. An incidental finding associated with this condition is a heel spur, a small bony calcification on the calcaneus (heel bone), which can be found in up to 50% of those with plantar fasciitis. In such cases, it is the underlying plantar fasciitis that produces the heel pain, and not the spur itself. The condition is responsible for the creation of the spur though the clinical significance of heel spurs in plantar fasciitis remains unclear.
Non Surgical Treatment
Most health care providers agree that initial treatment for plantar fasciitis should be quite conservative. You’ll probably be advised to avoid any exercise that is making your pain worse. Your doctor may also advise one or more of these treatment options. A heel pad. In plantar fasciitis, a heel pad is sometimes used to cushion the painful heel if you spend a great deal of time on your feet on hard surfaces. Also, over-the-counter or custom-made orthotics, which fit inside your shoes, may be constructed to address specific imbalances you may have with foot placement or gait. Stretching: Stretching exercises performed three to five times a day can help elongate the heel cord. Ice: You may be advised to apply ice packs to your heel or to use an ice block to massage the plantar fascia before going to bed each night. Pain relievers: Simple over-the-counter nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, are often helpful in decreasing inflammation and pain. If you have stomach trouble from such drugs, your health care provider may prescribe an alternative. A night splint: A night splint is sometimes used to hold your foot at a specific angle, which prevents the plantar fascia from shortening during sleep. Ultrasound: Ultrasound therapy can be performed to decrease inflammation and aid healing. Steroid injections: Anti-inflammatory steroid injections directly into the tissue around your heel may be temporarily helpful. However, if these injections are used too many times, you may suffer other complications, such as shrinking of the fat pad of your heel, which you need for insulation. Loss of the fat pad could actually increase your pain, or could even rupture the plantar fascia in rare cases. Walking cast: In cases of long-term plantar fasciitis unresponsive to usual treatments, your doctor may recommend that you wear a short walking cast for about three weeks. This ensures that your foot is held in a position that allows the plantar fascia to heal in a stretched, rather than shortened, position. Shock wave therapy, Extracorporeal shock wave therapy which may be prescribed prior to considering surgery if your symptoms have persisted for more than six months. This treatment does not involve any actual incisions being made rather it uses a high intensity shock wave to stimulate healing of the plantar fascia.
Like every surgical procedure, plantar fasciitis surgery carries some risks. Because of these risks your doctor will probably advise you to continue with the conventional treatments at least 6 months before giving you approval for surgery. Some health experts recommend home treatment as long as 12 months. If you can’t work because of your heel pain, can’t perform your everyday activities or your athletic career is in danger, you may consider a plantar fasciitis surgery earlier. But keep in mind that there is no guarantee that the pain will go away completely after surgery. Surgery is effective in many cases, however, 20 to 25 percent of patients continue to experience heel pain after having a plantar fasciitis surgery.
To reduce your risk of getting plantar fasciitis take these steps. Wear appropriate and well-fitted footwear during sports and exercise. Do stretching exercises for the Achilles tendon and plantar fascia. Increase the intensity and duration of exercise gradually. Maintain an appropriate weight.
