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.
Plantar fasciitis is one of those injuries that magically seems to appear for no apparent reason. However, plantar fasciitis is caused by one of two methods. They are either traction or compression
injuries. Plantar fasciitis is most often associated with impact and running sports, especially those that involve toe running rather than heel running styles. It is also commonly diagnosed in
individuals with poor foot biomechanics that stress the plantar fascia. Flat feet or weak foot arch control muscles are two common causes of plantar fasciitis.
A very common complaint of plantar fasciitis is pain in the bottom of the heel. Plantar fasciitis is usually worse in the morning and may improve throughout the day. By the end of the day the pain
may be replaced by a dull aching that improves with rest. Most people suffering from plantar fasciitis also complain of increased heel pain after walking for a long period of time.
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
First check your shoes for too much midfoot flexibility and check your training for changes. A detailed evaluation of changes in your training is necessary. You should start with what is called
"relative rest" which means a decrease in workout intensity, duration of session and decrease in the number of sessions per week. The most important part of self treatment for this condition is being
sure that your shoes offer sufficient stability and are optimal in controlling the forces that contribute to plantar fasciitis and heel spurs. Check your running shoes to make sure that they are not
excessively worn. They should bend only at the ball of the foot, where your toes attach to the foot. This is vital! Avoid any shoe that bends in the center of the arch or behind the ball of the foot.
It offers insufficient support and will stress your plantar fascia. The human foot was not designed to bend here and neither should a shoe be designed to do this. You should also be doing gentle calf
stretching exercises. This will reduce stress on the plantar fascia in two ways. The first manner in which a relaxation of the tension in the calf muscles can help heel pain is that it will reduce
the direct pull backwards on the heel bone (calcaneus). The second reason is a little bit more complicated, but essentially it is that a tight achilles tendon and calf muscles causes the rearfoot to
move in a manner that causes over pronation as your leg and body move forward over your foot. So go ahead and gently stretch the calf muscle by doing the runner's wall leaning stretch. To strengthen
the muscles in your arch toe curls or "doming" can be done. Toe curls may be done by placing a towel on a kitchen floor and then curling your toes to pull the towel towards you. This exercise may
also be done without the towel against the resistance of the floor.
In unusual cases, surgical intervention is necessary for relief of pain. These should only be employed after non-surgical efforts have been used without relief. Generally, such surgical procedures
may be completed on an outpatient basis in less than one hour, using local anesthesia or minimal sedation administrated by a trained anesthesiologist. In such cases, the surgeon may remove or release
the injured and inflamed fascia, after a small incision is made in the heel. A surgical procedure may also be undertaken to remove bone spurs, sometimes as part of the same surgery addressing the
damaged tissue. A cast may be used to immobilize the foot following surgery and crutches provided in order to allow greater mobility while keeping weight off the recovering foot during healing. After
removal of the cast, several weeks of physical therapy can be used to speed recovery, reduce swelling and restore flexibility.
