The plantar fascia is a strong, relatively inflexible, fibrous ligament band that runs through the bottom of the foot. That band helps to keep the complex arch system of the foot, absorb shock, plays
a role in body balance and in the various phases of gait. The band transmits your weight across the bottom of the foot with each step you take. When the heel of the trailing leg starts to get off the
ground, the band bears tension that is approximately twice the body weight. The tension on the band at this moment is even greater if the calf muscles are not flexible enough.
The cause of plantar fasciitis is poorly understood and is thought to likely have several contributing factors. The plantar fascia is a thick fibrous band of connective tissue that originates from
the medial tubercle and anterior aspect of the heel bone. From there, the fascia extends along the sole of the foot before inserting at the base of the toes, and supports the arch of the foot.
Originally, plantar fasciitis was believed to be an inflammatory condition of the plantar fascia. However, within the last decade, studies have observed microscopic anatomical changes indicating that
plantar fasciitis is actually due to a non-inflammatory structural breakdown of the plantar fascia rather than an inflammatory process. Due to this shift in thought about the underlying mechanisms in
plantar fasciitis, many in the academic community have stated the condition should be renamed plantar fasciosis. The structural breakdown of the plantar fascia is believed to be the result of
repetitive microtrauma (small tears). Microscopic examination of the plantar fascia often shows myxomatous degeneration, connective tissue calcium deposits, and disorganized collagen fibers.
Disruptions in the plantar fasciaâs normal mechanical movement during standing and walking (known as the Windlass mechanism) are thought to contribute to the development of plantar fasciitis by
placing excess strain on the calcaneal tuberosity.
You'll typically first notice early plantar fasciitis pain under your heel or in your foot arch in the morning or after resting. Your heel pain will be worse with the first steps and improves with
activity as it warms up. As plantar fasciitis deteriorates, the pain will be present more often. You can determine what stage your are in using the following guidelines. No Heel Pain, Normal! Heel
pain after exercise. Heel pain before and after exercise. Heel pain before, during and after exercise. Heel pain all the time. Including at rest! This symptom progression is consistent with the four
stages of a typical overuse injury. Ultimately, further trauma and delayed healing will result in the formation of calcium (bone) within the plantar fascia. When this occurs adjacent to the heel bone
it is known as heel spurs, which have a longer rehabilitation period.
Your doctor will check your feet and watch you stand and walk. He or she will also ask questions about your past health, including what illnesses or injuries you have had. Your symptoms, such as
where the pain is and what time of day your foot hurts most. How active you are and what types of physical activity you do. Your doctor may take an X-ray of your foot if he or she suspects a problem
with the bones of your foot, such as a stress fracture.
Non Surgical Treatment
A doctor may prescribe anti-inflammatory medication such as ibuprofen to help reduce pain and inflammation. Electrotherapy such as ultrasound or laser may also help with symptoms. An X-ray may be
taken to see if there is any bone growth or calcification, known as a heel spur but this is not necessarily a cause of pain. Deep tissue sports massage techniques can reduce the tension in and
stretch the plantar fascia and the calf muscles. Extracorporeal shock wave therapy has been known to be successful and a corticosteroid injection is also an option.
The most dramatic therapy, used only in cases where pain is very severe, is surgery. The plantar fascia can be partially detached from the heel bone, but the arch of the foot is weakened and full
function may be lost. Another surgery involves lengthening the calf muscle, a process called gastrocnemius recession. If you ignore the condition, you can develop chronic heel pain. This can change
the way you walk and cause injury to your legs, knees, hips and back. Steroid injections and some other treatments can weaken the plantar fascia ligament and cause potential rupture of the ligament.
Surgery carries the risks of bleeding, infection, and reactions to anesthesia. Plantar fascia detachment can also cause changes in your foot and nerve damage. Gastrocnemius resection can also cause
