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 most commonly occurs due to repetitive or prolonged activities placing strain on the plantar fascia. It is often seen in runners, or dancers and gymnasts who perform regular activities involving end of range foot and ankle movements. It may also occur in patients who walk excessively, especially up hills or on uneven surfaces. Older patients who spend a lot of time on their feet may also develop the condition. Plantar fasciitis frequently occurs in association with calf muscle tightness, inappropriate footwear, or biomechanical abnormalities, such as excessive pronation (flat feet) or supination (high arches). Occasionally the condition may occur suddenly due to a high force going through the plantar fascia beyond what it can withstand. This may be due to activities such as a sudden acceleration or a forceful jump.
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.
X-rays are a commonly used diagnostic imaging technique to rule out the possibility of a bone spur as a cause of your heel pain. A bone spur, if it is present in this location, is probably not the cause of your pain, but it is evidence that your plantar fascia has been exerting excessive force on your heel bone. X-ray images can also help determine if you have arthritis or whether other, more rare problems, stress fractures, bone tumors-are contributing to your heel pain.
Non Surgical Treatment
Talk to your doctor about the best treatment plan for you. Options include. Apply ice or a cold pack to the heel and arch for 15 to 20 minutes several times a day. Wrap the ice or cold pack in a towel. Do not apply the ice directly to your skin. A special splint that will hold your foot in a neutral position while sleeping. Special shoe inserts that support the mid-arch region of your foot. Inserts that are not customized may work just as well as those that are customized. Activity. Avoid running and other activities that may worsen pain. Begin stretching exercises to lengthen the Achilles tendon and plantar fascia as recommended by your doctor. This is usually done when pain has lessened or improved. To help manage pain, your doctor may recommend over-the-counter nonsteroidal anti-inflammatory medication (NSAIDs), such as ibuprofen or naproxen. Prescription pain relievers may also be required. Steroid injections may be used in some cases or if other treatment is not working. A special type of sound wave called extracorporeal shock wave may also be considered in certain cases. This treatment happens under the care of your doctor. At this time, this is generally a treatment for long-term cases that do not respond to other treatments. Massage therapy or accupuncture may also be effective for long-term cases. In a few cases, basic treatments don’t help. Surgery may be performed to cut the tight, swollen fascia.
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 nerve damage.
