Foot pain affects nearly all people at one time or another. It can also lead to other musculoskeletal problems such as ankle, knee and back pain (Hill et al., 2008). This pain negatively affects one’s quality of life and ability to enjoy workouts and/or maintain a regular program of exercise. One of the most common sources of foot pain is plantar fasciitis, a condition where the connective tissue on the underside of the foot becomes irritated and painful as a result of an injury, overuse or misuse. The plantar fascia is a system of connective tissue that runs from your heel to just behind your toes. During weightbearing activities, such as walking or running, your body weight is transferred onto your foot from your heel to your toes (which results in your toes moving away from your heel). This spreading out of the foot places tension on the plantar fascia because it connects those two parts. If the tension on this structure is too great or is not dispersed evenly, the plantar fascia can develop microtears and become irritated and painful, resulting in a condition called plantar fasciitis.
It usually starts following an increase in activity levels. Increase in weight. Standing for long periods. Poor footwear. Tight muscle groups. Abnormal pressure on the plantar Fascia can be caused by any of the above. The plantar fascia becomes inflamed and tiny rips can occur where it attaches into the inside of the heel bone. The area becomes inflamed and swollen, and it is the increase in fluid to the area that accumulates when weight is taken off the area that then causes the pain on standing.
The heel pain characteristic of plantar fasciitis is usually felt on the bottom of the heel and is most intense with the first steps of the day. Individuals with plantar fasciitis often have difficulty with dorsiflexion of the foot, an action in which the foot is brought toward the shin. This difficulty is usually due to tightness of the calf muscle or Achilles tendon, the latter of which is connected to the back of the plantar fascia. Most cases of plantar fasciitis resolve on their own with time and respond well to conservative methods of treatment.
A physical exam performed in the office along with the diagnostic studies as an x-ray. An MRI may also be required to rule out a stress fracture, or a tear of the plantar fascia. These are conditions that do not normally respond to common plantar fasciitis treatment.
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.
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.
The best way to prevent plantar fasciitis is to wear shoes that are well made and fit your feet. This is especially important when you exercise or walk a lot or stand for a long time on hard surfaces. Get new athletic shoes before your old shoes stop supporting and cushioning your feet. You should also avoid repeated jarring to the heel. Keep a healthy weight. Do your leg and foot stretching exercises regularly.
