Plantar Fasciitis

Plantar fasciitis is one of the most common causes of heel pain. It involves inflammation of a thick band of tissue that runs across the bottom of your foot and connects your heel bone to your toes (plantar fascia).

Plantar fasciitis commonly causes stabbing pain that usually occurs with your first steps in the morning. As you get up and move, the pain normally decreases, but it might return after long periods of standing or when you stand up after sitting. Plantar fasciitis is more common in runners. People who are overweight and those who wear shoes with inadequate support also have an increased risk of plantar fasciitis.

Plantar Fasciitis

Causes of Plantar Fasciitis

The plantar fascia is designed to absorb the high stresses and strains we place on our feet. But, sometimes, too much pressure damages or tears the tissues. The body’s natural response to injury is inflammation, which results in the heel pain and stiffness of plantar fasciitis.

Risk Factors

In most cases, plantar fasciitis develops without a specific, identifiable reason. There are, however, many factors that can make you more prone to the condition:

  • Age. Plantar fasciitis is most common between the ages of 40 and 60.
  • Certain types of exercise. Activities that place a lot of stress on your heel and attached tissue — such as long-distance running, ballet dancing and aerobic dance — can contribute to the onset of plantar fasciitis.
  • Foot mechanics. Flat feet, a high arch or even an abnormal pattern of walking can affect the way weight is distributed when you’re standing and can put added stress on the plantar fascia.
  • Obesity. Excess pounds put extra stress on your plantar fascia.
  • Occupations that keep you on your feet. Factory workers, teachers and others who spend most of their work hours walking or standing on hard surfaces can damage the plantar fascia.

Symptoms

The most common symptoms of plantar fasciitis include:

  • Pain on the bottom of the foot near the heel
  • Pain with the first few steps after getting out of bed in the morning, or after a long period of rest, such as after a long car ride. The pain subsides after a few minutes of walking
  • Greater pain after (not during) exercise or activity

Doctor Examination and Diagnosis

Plantar fasciitis is diagnosed based on your medical history and physical examination. During the exam, your Doctor/specialist at Westminster Ortho Med Clinic, Dubai will check for areas of tenderness in your foot. The location of your pain can help determine its cause. Your doctor will look for these signs:

  • A high arch
  • An area of maximum tenderness on the bottom of your foot, just in front of your heel bone
  • Pain that gets worse when you flex your foot and the doctor pushes on the plantar fascia. The pain improves when you point your toes down
  • Limited “up” motion of your ankle.

Imaging tests

Usually no tests are necessary. Your doctor might suggest an X-ray or magnetic resonance imaging (MRI) to make sure another problem, such as a stress fracture, is not causing you pain.

Sometimes an X-ray shows a piece of bone sticking out (spur) from the heel bone. In the past, these bone spurs were often blamed for heel pain and removed surgically. But many people who have bone spurs on their heels have no heel pain.

Treatment:

Nonsurgical Treatment

More than 90% of patients with plantar fasciitis will improve within 10 months of starting simple treatment methods.

  • Rest: Decreasing or even stopping the activities that make the pain worse is the first step in reducing the pain. You may need to stop athletic activities where your feet pound on hard surfaces (for example, running or step aerobics).
  • Ice: Rolling your foot over a cold water bottle or ice for 20 minutes is effective. This can be done 3 to 4 times a day.
  • Nonsteroidal anti-inflammatory medication. Anti-inflammatory drugs can reduce the pain and inflammation. Using the medication for more than 1 month should be reviewed with your primary care doctor.
  • Exercise. Plantar fasciitis is aggravated by tight muscles in your feet and calves. Stretching your calves and plantar fascia is the most effective way to relieve the pain that comes with this condition.
  • Calf stretch
    Lean forward against a wall with one knee straight and the heel on the ground. Place the other leg in front, with the knee bent. To stretch the calf muscles and the heel cord, push your hips toward the wall in a controlled fashion. Hold the position for 10 seconds and relax. Repeat this exercise 20 times for each foot. A strong pull in the calf should be felt during the stretch.
  • Plantar fascia stretch
    This stretch is performed in the seated position. Cross your affected foot over the knee of your other leg. Grasp the toes of your painful foot and slowly pull them toward you in a controlled fashion. If it is difficult to reach your foot, wrap a towel around your big toe to help pull your toes toward you. Place your other hand along the plantar fascia. The fascia should feel like a tight band along the bottom of your foot when stretched. Hold the stretch for 10 seconds. Repeat it 20 times for each foot. This exercise is best done in the morning before standing or walking.
  • Cortisone injections. Cortisone, a type of steroid, is a powerful anti-inflammatory medication. It can be injected into the plantar fascia to reduce inflammation and pain. Your doctor may limit your injections. Multiple steroid injections can cause the plantar fascia to rupture (tear), which can lead to a flat foot and chronic pain.
  • Supportive shoes and orthotics. Shoes with thick soles and extra cushioning can reduce pain with standing and walking. As you step and your heel strikes the ground, a significant amount of tension is placed on the fascia, which causes microtrauma (tiny tears in the tissue). A cushioned shoe or insert reduces this tension and the microtrauma that occurs with every step. Soft silicone heel pads are inexpensive and work by elevating and cushioning your heel. Pre-made or custom orthotics (shoe inserts) are also helpful. Soft heel pads can provide extra support.
  • Night splints. Most people sleep with their feet pointed down. This relaxes the plantar fascia and is one of the reasons for morning heel pain. A night splint stretches the plantar fascia while you sleep. Although it can be difficult to sleep with, a night splint is very effective and does not have to be used once the pain is gone.
  • Physical therapy. Your doctor may suggest that you work with a physical therapist on an exercise program that focuses on stretching your calf muscles and plantar fascia. In addition to exercises like the ones mentioned above, a physical therapy program may involve specialized ice treatments, massage, and medication to decrease inflammation around the plantar fascia.
  • Extracorporeal shockwave therapy (ESWT). During this procedure, high-energy shockwave impulses stimulate the healing process in damaged plantar fascia tissue. ESWT is noninvasive—it does not require a surgical incision. Because of the minimal risk involved, ESWT is tried before surgery is considered.

Surgical Treatment

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.

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.

Recovery. Most patients have good results from surgery. However, because surgery can result in chronic pain and dissatisfaction, it is recommended only after all nonsurgical measures have been exhausted.
