Plantar fasciitis is a painful condition affecting the connective tissue that stretches between the heel and the middle of the foot. It is usually caused by overuse, injury or muscular abnormalities.
In extracorporeal shockwave therapy, a machine is used to deliver sound waves to the painful area. It is not known exactly how it works, but it is thought that it might stimulate healing of the
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.
The symptoms of plantar fasciitis include pain in the bottom of your foot, especially at the front or centre of the heel bone, pain that is worse when first rising in the morning (called "first-step
pain"), when first standing up after any long period of sitting, or after increased levels of activity especially in non-supportive shoes. Seek medical advice about plantar fasciitis if you have heel
pain or pain in the bottom of your foot, especially when you get up in the morning, that does not respond to treatment or if there is redness or bruising in the heel.
To arrive at a diagnosis, the foot and ankle surgeon will obtain your medical history and examine your foot. Throughout this process the surgeon rules out all the possible causes for your heel pain
other than plantar fasciitis. In addition, diagnostic imaging studies such as x-rays or other imaging modalities may be used to distinguish the different types of heel pain. Sometimes heel spurs are
found in patients with plantar fasciitis, but these are rarely a source of pain. When they are present, the condition may be diagnosed as plantar fasciitis/heel spur syndrome.
Non Surgical Treatment
About 90% of plantar fasciitis cases are self-limited and will improve within six months with conservative treatment and within a year regardless of treatment. Many treatments have been proposed for
the treatment of plantar fasciitis. First-line conservative approaches include rest, heat, ice, calf-strengthening exercises, techniques to stretch the calf muscles, achilles tendon, and plantar
fascia, weight reduction in the overweight or obese, and nonsteroidal anti-inflammatory drugs (NSAIDs) such as aspirin or ibuprofen. NSAIDs are commonly used to treat plantar fasciitis, but fail to
resolve the pain in 20% of people. Extracorporeal shockwave therapy (ESWT) is an effective treatment modality for plantar fasciitis pain unresponsive to conservative nonsurgical measures for at least
three months. Corticosteroid injections are sometimes used for cases of plantar fasciitis refractory to more conservative measures. The injections may be an effective modality for short-term pain
relief up to one month, but studies failed to show effective pain relief after three months. Notable risks of corticosteroid injections for plantar fasciitis include plantar fascia rupture, skin
infection, nerve or muscle injury, or atrophy of the plantar fat pad. Custom orthotic devices have been demonstrated as an effective method to reduce plantar fasciitis pain for up to 12 weeks. Night
splints for 1-3 months are used to relieve plantar fasciitis pain that has persisted for six months. The night splints are designed to position and maintain the ankle in a neutral position thereby
passively stretching the calf and plantar fascia overnight during sleep. Other treatment approaches may include supportive footwear, arch taping, and physical therapy.
Surgery is usually not needed for plantar fasciitis. About 95 out of 100 people who have plantar fasciitis are able to relieve heel pain without surgery. Your doctor may consider surgery if
non-surgical treatment has not helped and heel pain is restricting your daily activities. Some doctors feel that you should try non-surgical treatment for at least 6 months before you consider
surgery. The main types of surgery for plantar fasciitis are Plantar fascia release. This procedure involves cutting part of the plantar fascia ligament . This releases the tension on the ligament
and relieves inflammation . Other procedures, such as removing a heel spur or stretching or loosening specific foot nerves. These surgeries are usually done in combination with plantar fascia release
when there is lasting heel pain and another heel problem. Experts in the past thought that heel spurs caused plantar fasciitis. Now experts generally believe that heel spurs are the result, not the
cause, of plantar fasciitis. Many people with large heel spurs never have heel pain or plantar fasciitis. So surgery to remove heel spurs is rarely done.
You can help to prevent plantar fasciitis by maintaining a healthy weight, by warming up before participating in sports and by wearing shoes that support the arch and cushion the heel. In people who
are prone to episodes of plantar fasciitis, exercises that stretch the heel cord (known as the Achilles tendon) and the plantar fascia may help to prevent plantar fasciitis from returning. Ice
massage also can be used on the bottom of the foot after stressful athletic activities. It is possible that strict control of blood sugar will prevent plantar fasciitis in people with diabetes,
although this has not been proven.
