Overview
The plantar fascia is a sturdy structure but the degree of stress that it takes makes it susceptible to injury. A force equal to almost three times body weight passes through the foot with each step. On running, this typically happens about 90 times a minute. Plantar fasciitis is thought to be a traction and overuse injury. Damage to the plantar fascia is usually in the form of micro-tears. It is a degenerative rather than an inflammatory process. Damage tends to occur near the heel, where stress on the fibres is greatest, and where the fascia is the thinnest. The fascia broadens as it extends toward the toes. Plantar fasciitis is often associated with calcaneal spurs. These are depositions of calcium where the fascia suffers most damage. Spurs are most commonly on the medial side at the origin of the fascia from the calcaneum. Spurs are the result of the process of plantar fasciitis and not the cause of the pain. It can present bilaterally.
Causes
The most common acquired flat foot in adults is due to Posterior Tibial Tendon Dysfunction. This develops with repetitive stress on the main supporting tendon of the arch over a long period of time. As the body ages, ligaments and muscles can weaken, leaving the job of supporting the arch all to this tendon. The tendon cannot hold all the weight for long, and it gradually gives out, leading to a progressively lower arch. This form of flat foot is often accompanied by pain radiating behind the ankle, consistent with the course of the posterior tibial tendon. Compounding matters is the fact that the human foot was not originally designed to withstand the types of terrain and forces it is subjected to today. Nowhere in nature do you see the flat hard surfaces that we so commonly walk on in present times. Walking on this type of surface continuously puts unnatural stress on the arch. The fact that the average American is overweight does not help the arch much either-obesity is a leading cause of flat feet as the arch collapses under the excessive bodyweight. Furthermore, the average life span has increased dramatically in the last century, meaning that not only does the arch deal with heavy weight on hard flat ground, but also must now do so for longer periods of time. These are all reasons to take extra care of our feet now in order to prevent problems later.
Symptoms
If you've ever seen your footprints in the sand and they looked more like bricks than feet, then you probably have flat feet. Simply stated, a flat foot is a foot that does not have an arch when standing. In the medical world, flat feet are associated with "pronated" feet. Pronated is merely the term used to describe the position of the foot when it is flexed upward (dorsiflexed), turned away from the body (abducted), and the heel is rolled outward (everted), all at the same time. A certain amount of pronation is required for normal walking, but too much pronation is often considered a foot's "worst enemy." Over time, excessive pronation can lead to many unpleasant problems including heel pain, bunions, hammertoes, shin splints, and even knee, hip, or back pain. In fact, one orthopedic surgeon discovered that 95% of his total knee replacement patients and 90% of his total hip replacement patients had flat feet. An easy way to tell if you pronate too much is to take a look at your athletic shoes-excessive wearing of the inside heel (arch side of the shoe) as compared to the outside is a classic indication of excessive pronation.
Diagnosis
Magnetic Resonance Imaging (MRI) can show tendon injury and inflammation but cannot be relied on with 100% accuracy and confidence. The technique and skill of the radiologist in properly positioning the foot with the MRI beam are critical in demonstrating the sometimes obscure findings of tendon injury around the ankle. Magnetic Resonance Imaging (MRI) is expensive and is not necessary in most cases to diagnose posterior tibial tendon injury. Ultrasound has also been used in some cases to diagnose tendon injury, but this test again is usually not required to make the initial diagnosis.
Non Surgical Treatment
Though most FFF are asymptomatic (no pain or discomfort), they should still be addressed as it is not normal to have flat feet. Obviously it is always ideal to prevent a problem rather than treat it after it occurs, especially if FFF is being treated post-foot development. As mentioned earlier, barefoot is the best way to prevent FFF and a host of other foot and gait imbalances. To truly strengthen the entire foot and all the arches, it?s important to position the foot correctly at all times so when wearing something on the feet, footwear should be flat, firm, and flexible. This means that the shoe should not have a significant, or any, heel to toe drop, there should be little to no cushion or padding in the sole, and the shoe should not be rigid anywhere - it should bend throughout the shoe and in any direction. The shoe should also be wide at the toe box allowing the toes to naturally splay apart.
Surgical Treatment
Although most patients with plantar fasciitis respond to non- surgical treatment, a small percentage of patients may require surgery. If, after several months of non-surgical treatment, you continue to have heel pain, surgery will be considered. Your foot and ankle surgeon will discuss the surgical options with you and determine which approach would be most beneficial. No matter what kind of treatment you undergo for plantar fasciitis, the underlying causes that led to this condition may remain. Therefore, you will need to continue with preventive measures. Wearing supportive shoes, stretching, and using custom orthotic devices are the mainstays of long-term treatment for plantar fasciitis.
Prevention
Stretch and strengthen important muscles in your feet, ankles and legs in order to guard against future strain. Make sure to acquire suitable arch supports and inserts if necessary, and that your shoes are shock absorbent and in good condition. Wearing tattered shoes provides no protection, and runners should replace their footwear before exceeding 500 miles of usage. Athletes new to arch supports should gradually build their training routine, allowing their feet to become accustomed to a new stance.
Stretching Exercises
Plantar Fasciitis stretches should always be gentle and pain free, if discomfort occurs with or after stretching decrease the intensity and duration of stretches. Stretches can usually be gradually progressed in intensity and duration over time according to individual tolerance. Plantar Fasciitis Stretch 1. Stretch for the right calf muscle (gastrocnemius) and the arch of the right foot (plantar fascia and muscles under the arches). Take your right heel close to the wall and ball of the foot upright against the wall. Move your hips forwards to the wall. Try to keep your right leg straight. Push down through your right heel to increase the stretch. Maintain for 30 seconds, repeat 2-3 times. Plantar Fasciitis Stretch 2. Stretch for the outside belly of the right calf muscle and the arch of the right foot. Take your right heel close to the wall. Turn the ball of your right foot outwards to 2 o?clock position upright against the wall. Move your hips forwards to the wall. Turn your trunk in the opposite direction (i.e. to the left). Try to keep your right leg straight. Push down through your right heel to increase the stretch. Maintain for 30 seconds, repeat 2-3 times. Plantar Fasciitis Stretch 3. Stretch for the inside belly of the right calf muscle and the arch of the right foot. Take your right heel close to the wall. Turn the ball of your right foot inwards to 10 o?clock position upright against the wall. Move your hips forwards to the wall. Turn your trunk in the opposite direction (i.e. to the right). Try to keep your right leg straight. Push down through your right heel to increase the stretch. Maintain for 30 seconds, repeat 2-3 times. Plantar Fasciitis Stretch 4. Stretch for the right achilles tendon and the arch of the right foot. Take your right heel close to the wall and ball of the foot upright against the wall (as for stretch 1). Move your hips forwards to the wall. Bend your right knee forwards into the wall keeping the ball of your foot upright against the wall. Push down through your right heel to increase the stretch. Maintain for 30 seconds, repeat 2-3 times.
