Plantar Fasciitis is an inflammation caused by excessive stretching of the plantar fascia. The plantar fascia is a broad band of fibrous tissue which runs along the bottom surface of the foot, attaching at the bottom of the heel bone and extending to the forefoot. When the plantar fascia is excessively stretched, this can cause plantar fasciitis, which can also lead to heel pain, arch pain, and heel spurs.
Plantar fasciitis is the most common injury of the plantar fascia and is the most common cause of heel pain. Approximately 10% of people have plantar fasciitis at some point during their lifetime. It is commonly associated with long periods of standing and is much more prevalent in individuals with excessive inward rolling of the foot, which is seen with flat feet. Among non-athletic populations, plantar fasciitis is associated with obesity and lack of physical exercise.
The heel pain characteristic of plantar fasciitis is usually felt on the bottom of the heel and is most intense with the first steps of the day. Individuals with plantar fasciitis often have difficulty with dorsiflexion of the foot, an action in which the foot is brought toward the shin. This difficulty is usually due to tightness of the calf muscle or Achilles tendon, the latter of which is connected to the back of the plantar fascia. Most cases of plantar fasciitis resolve on their own with time and respond well to conservative methods of treatment.
Plantar fasciosis is confirmed if firm thumb pressure applied to the calcaneus when the foot is dorsiflexed elicits pain. Fascial pain along the plantar medial border of the fascia may also be present. If findings are equivocal, demonstration of a heel spur on x-ray may support the diagnosis; however, absence does not rule out the diagnosis, and visible spurs are not generally the cause of symptoms. Also, infrequently, calcaneal spurs appear ill defined on x-ray, exhibiting fluffy new bone formation, suggesting spondyloarthropathy (eg, ankylosing spondylitis, reactive arthritis. If an acute fascial tear is suspected, MRI is done.
Non Surgical Treatment
A steroid (cortisone) injection is sometimes tried if your pain remains bad despite the above 'conservative' measures. It may relieve the pain in some people for several weeks but does not always cure the problem. It is not always successful and may be sore to have done. Steroids work by reducing inflammation. Sometimes two or three injections are tried over a period of weeks if the first is not successful. Steroid injections do carry some risks, including (rarely) tearing (rupture) of the plantar fascia. Extracorporeal shock-wave therapy. In extracorporeal shock-wave therapy, a machine is used to deliver high-energy sound waves through your skin to the painful area on your foot. It is not known exactly how it works, but it is thought that it might stimulate healing of your plantar fascia. One or more sessions of treatment may be needed. This procedure appears to be safe but it is uncertain how well it works. This is mostly because of a lack of large, well-designed clinical trials. You should have a full discussion with your doctor about the potential benefits and risks. In studies, most people who have had extracorporeal shock-wave therapy have little in the way of problems. However, possible problems that can occur include pain during treatment, skin reddening, and swelling of your foot or bruising. Another theoretical problem could include the condition getting worse because of rupture of your plantar fascia or damage to the tissues in your foot. More research into extracorporeal shock-wave therapy for plantar fasciitis is needed. Other treatments. Various studies and trials have been carried out looking at other possible treatments for plantar fasciitis. Such treatments include injection with botulinum toxin and treatment of the plantar fascia with radiotherapy. These treatments may not be widely available. Some people benefit from wearing a special splint overnight to keep their Achilles tendon and plantar fascia slightly stretched. The aim is to prevent the plantar fascia from tightening up overnight. In very difficult cases, sometimes a plaster cast or a removable walking brace is put on the lower leg. This provides rest, protection, cushioning and slight stretching of the plantar fascia and Achilles tendon. However, the evidence for the use of splint treatment of plantar fasciitis is limited.
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.
While it's typical to experience pain in just one foot, massage and stretch both feet. Do it first thing in the morning, and three times during the day. Achilles Tendon Stretch. Stand with your affected foot behind your healthy one. Point the toes of the back foot toward the heel of the front foot, and lean into a wall. Bend the front knee and keep the back knee straight, heel firmly planted on the floor. Hold for a count of 10. Plantar Fascia Stretch. Sit down, and place the affected foot across your knee. Using the hand on your affected side, pull your toes back toward your shin until you feel a stretch in your arch. Run your thumb along your foot--you should feel tension. Hold for a count of 10.
