Plantar fasciitis is a common painful disorder affecting the heel and underside of the foot. It is a disorder of the insertion site of plantar fascia on the bone and is characterized by scarring, inflammation, or structural breakdown of the foot’s plantar fascia. It is often caused by overuse injury of the plantar fascia, increases in exercise, weight or age. Although plantar fasciitis was originally thought to be an inflammatory process, newer studies have demonstrated structural changes more consistent with a degenerative process. As a result of this new observation, many in the academic community have stated the condition should be renamed plantar fasciosis.
Plantar Fasciitis is simply caused by overstretching of the plantar fascia ligament under the foot. So why is the ligament being overstretched? There are different factors, over-use, too much sports, running, walking or standing for long periods (e.g. because of your job) weight gain, our feet are designed to carry a 'normal' weight. Any excess weight places great pressure on the bones, nerves, muscles and ligaments in the feet, which sooner or later will have consequences. Even pregnancy (in the last 10 weeks) can cause foot problems! age, as we get older ligaments become tighter & shorter and msucles become weaker; the ideal circumstances for foot problems, unsupportive footwear, 'floppy' shoes with no support as well as thongs affect our walking pattern, walking barefoot, especially on hard surfaces like concrete or tiles, low arch and flat feet or over-pronation. An important contributing factor to Plantar Fasciitis is 'excess pronation' (or over-pronation). This is a condition whereby the feet roll over, the arches collapse and the foot elongates. This unnatural elongation puts excess strain on the ligaments, muscles and nerves in the foot. When the foot is not properly aligned, the bones unlock and cause the foot to roll inward. With every step taken your foot pronates and elongates, stretching the plantar fascia and causing inflammation and pain at the attachment of the plantar fascia into the heel bone. Re-alignment of the foot should therefore an important part of the treament regime.
Plantar fascia usually causes pain and stiffness on the bottom of your heel although some people have heel spurs and suffer no symptoms at all. Occasionally, heel pain is also associated with other medical disorders such as arthritis (inflammation of the joint), bursitis (inflammation of the tissues around the joint). Those who have symptoms may experience ‘First step’ pain (stone bruise sensation) after getting out of bed or sitting for a period of time. Pain after driving. Pain on the bottom of your heel. Deep aching pain. Pain can be worse when barefoot.
Plantar fasciitis is one of many conditions causing "heel pain". Some other possible causes include nerve compression either in the foot or in the back, stress fracture of the calcaneus, and loss of the fatty tissue pad under the heel. Plantar fasciitis can be distinguished from these and other conditions based on a history and examination done by a physician. It should be noted that heel spurs are often inappropriately thought to be the sole cause of heel pain. In fact, heel spurs are common and are nothing more than the bone's response to traction or pulling-type forces from the plantar fascia and other muscles in the foot where they attach to the heel bone. They are commonly present in patients without pain, and frequently absent from those who have pain. It is the rare patient who has a truly enlarged and problematic spur requiring surgery.
Non Surgical Treatment
Night splints are treatment that can help stretch your calf and the arch of your foot. Night splints are a type of brace that holds your foot in a flexed position and lengthens the plantar fascia and Achilles tendon overnight. This can prevent morning pain and stiffness. Special orthotics, or arch supports, for your shoes may help alleviate some of the pain by distributing pressure, and can prevent further damage to the plantar fascia. A boot cast may be used to immobilize your foot and reduce strain while the plantar fascia heals. A boot cast looks like a ski boot and can be removed for bathing.
Surgery is considered only after 12 months of aggressive nonsurgical treatment. Gastrocnemius recession. This is a surgical lengthening of the calf (gastrocnemius) muscles. Because tight calf muscles place increased stress on the plantar fascia, this procedure is useful for patients who still have difficulty flexing their feet, despite a year of calf stretches. In gastrocnemius recession, one of the two muscles that make up the calf is lengthened to increase the motion of the ankle. The procedure can be performed with a traditional, open incision or with a smaller incision and an endoscope, an instrument that contains a small camera. Your doctor will discuss the procedure that best meets your needs. Complication rates for gastrocnemius recession are low, but can include nerve damage. Plantar fascia release. If you have a normal range of ankle motion and continued heel pain, your doctor may recommend a partial release procedure. During surgery, the plantar fascia ligament is partially cut to relieve tension in the tissue. If you have a large bone spur, it will be removed, as well. Although the surgery can be performed endoscopically, it is more difficult than with an open incision. In addition, endoscopy has a higher risk of nerve damage.
Do your best to maintain healthy weight. Plantar fasciitis is caused by wear and tear on your feet. Being overweight drastically increases the pounding your feet take every day. Even losing a few pounds can help reduce heel pain. Avoid jobs that require walking or standing for long periods of time. Having your body weight on your feet all day puts a lot of pressure on your plantar fascia tissue. Replace your shoes on a regular basis. Buy new shoes when the old ones are worn-out. Make sure your shoes will fit your foot size comfortably at the end of the day. Pay attention to the width as well as the length. Use good supportive shoes that will help you with your original problem like arch support, motion control, stability, cushioning etc. Stretch regularly as part of your daily routine. There are a few special stretching techniques for the prevention. Choose soft surfaces for your exercise routine to walk, jog or run on. Rest and elevate your feet every chance you have. Strengthen your foot muscles as part of your exercise routine. Strong foot muscles provide a good support to the plantar fascia. Change your shoes during the work week. Don't wear the same pair of shoes every day. Perform Warm up exercises such as a short period of walking, a light jog or other easy movement and then stretch before starting the main exercise. Try to avoid dramatic changes in your exercise routine. Increase your exercise level gradually. Don’t run long distance if you are used to walk. Make the change slowly and gradually. Pay attention to your foot pain, do not ignore it. Visit your doctor if the pain continues. Avoid the activities that cause you pain. Use over-the-counter Orthotics or inserts that your doctor may prescribe. Off-the-shelf or custom-fitted arch supports (orthotics) will help distribute pressure to your feet more evenly. Try to avoid barefoot walking, since it may add stress on the plantar fascia ligament.
