Plantar fasciitis is a common cause of heel pain in adults. The pain is usually caused by collagen degeneration (which is sometimes misnamed “chronic inflammation”) at the origin of the plantar fascia at the medial tubercle of the calcaneus. This degeneration is similar to the chronic necrosis of tendonosis, which features loss of collagen continuity, increases in ground substance (matrix of connective tissue) and vascularity, and the presence of fibro-blasts rather than the inflammatory cells usually seen with the acute inflammation of tendonitis. The cause of the degeneration is repetitive microtears of the plantar fascia that overcome the body's ability to repair itself.
Plantar fasciitis tends to strike those who overtrain, neglect to stretch their calf muscles, or overdo hill work and speedwork. Plantar fasciitis can also be caused by biomechanical flaws, including flat, high-arched feet and a tight Achilles tendon; excessive pronation; sudden increases in training mileage; beginning speedwork; wearing worn running shoes; running on hard surfaces, like asphalt or concrete; or wearing high heels all day before switching into flat running shoes.
When a patient has plantar fasciitis, the connective tissue that forms the arch of the foot becomes inflamed (tendonitis) and degenerative (tendinosis)--these abnormalities cause plantar fasciitis and can make normal activities quite painful. Symptoms of plantar fasciitis are typically worsened early in the morning after sleep. At that time, the arch tissue is tight and simple movements stretch the contracted tissue. As you begin to loosen the foot, the pain usually subsides, but often returns with prolonged standing or walking.
Plantar fasciitis is usually diagnosed by a health care provider after consideration of a person’s presenting history, risk factors, and clinical examination. Tenderness to palpation along the inner aspect of the heel bone on the sole of the foot may be elicited during the physical examination. The foot may have limited dorsiflexion due to tightness of the calf muscles or the Achilles tendon. Dorsiflexion of the foot may elicit the pain due to stretching of the plantar fascia with this motion. Diagnostic imaging studies are not usually needed to diagnose plantar fasciitis. However, in certain cases a physician may decide imaging studies (such as X-rays, diagnostic ultrasound or MRI) are warranted to rule out other serious causes of foot pain. Bilateral heel pain or heel pain in the context of a systemic illness may indicate a need for a more in-depth diagnostic investigation. Lateral view x-rays of the ankle are the recommended first-line imaging modality to assess for other causes of heel pain such as stress fractures or bone spur development. Plantar fascia aponeurosis thickening at the heel greater than 5 millimeters as demonstrated by ultrasound is consistent with a diagnosis of plantar fasciitis. An incidental finding associated with this condition is a heel spur, a small bony calcification on the calcaneus (heel bone), which can be found in up to 50% of those with plantar fasciitis. In such cases, it is the underlying plantar fasciitis that produces the heel pain, and not the spur itself. The condition is responsible for the creation of the spur though the clinical significance of heel spurs in plantar fasciitis remains unclear.
Non Surgical Treatment
The following self-help treatments have been found to be most effective. Rest your foot. Reduce the amount of weight-bearing activities you participate in. Get off of your feet and elevate them. This will allow healing to begin. Apply ice to your foot. Applications of ice packs that provide a comfortable cooling to the heel and arch (not a freezing cold) will help reduce pain, swelling, and inflammation. Apply the ice to the heel and arch (not the toes). Make sure it is comfortable, and leave on your foot for about 20 minutes, 3 times a day. If you have any medical problems such as diabetes, poor circulation, etc., discuss the use of ice with your doctor before applying the ice. ActiveWrap allows you to apply comfortable cold therapy to your foot without messy ice cubes. Use while on the "go." Do not walk with bare feet. Always protect your heels, arches, and plantar fascia with good supportive shoes. Orthaheel Orthotic Flip Flops For Men and Women are designed for walking comfort with built in orthotic footbeds that help reduce foot pain from plantar fasciitis. Use in the house or on the beach. Stretch the Plantar Fascia while sleeping. Plantar Fasciitis and Heel Spur pain is usually worse with the first steps in the morning. This is due to the Plantar Fascia tightening up, or contracting while we sleep. To prevent these pain producing contractures of the plantar fascia, the foot must be held in its normal or neutral position while we sleep. This optimal position of the foot is maintained with our comfortable and supportive Night Splint. When foot contractures are prevented during sleep, the "first step pains" Plantar Fasciitis and Heel Spurs will gradually subside. Stretch the Plantar Fascia during the day. Even though the Plantar Fascia is a thick tissue band with very little "give" to it, with the proper care (a Night Splint and the following exercises) it can be stretched a small amount. By stretching the Plantar Fascia even a bit, its abnormal pull on the heel is reduced. This will help to reduce pain and inflammation in the heel and arch. Two of the most effective exercises recommended are. Before stepping down, especially after sleeping or resting, stretch the arch of the foot by stretching your legs out in front of you (do not bend the knee). Place a towel around the ball of the foot. Slowly pull on the ends of the towel, pulling the toes and ball of the foot back as far as is comfortable. Hold the foot in this position for ten seconds. Repeat at least ten times. You should feel a pull on the bottom of the foot, especially in the arch. This stretches the plantar fascia, and reduces its pull on the heel. Stand about 2 to 3 feet from a wall. Lean forward with your hands against the wall. With the painful foot behind, place the other foot forward. Press against the wall, shifting weight over the front foot, while straightening the back leg. Keep the heel of the back foot on the floor and feel the stretch in the heel, Achilles tendon, and calf. Hold this position for ten seconds. Repeat at least ten times, and try to do this three times a day. When these things are achieved, the inflammation and pain of Plantar Fasciitis and Heel Spurs will gradually subside. If you are unsure of the nature of your foot problem, if your pain is intense and does not subside, if you are a diabetic or have other medical problems, if your pain is due to an injury, if an open sore is present, if a mass can be felt, or if you think that you may have an infection, we suggest that before beginning any of the above treatments you consult with your doctor.
Surgery is not a common treatment for this condition. Approximately 5% of people with plantar fasciitis require surgery if non-surgical methods do not help to relieve pain within a year. The surgical procedure involves making an incision in the plantar fascia in order to decrease the tension of the ligament. Potential risks of this surgical procedure include irritation of the nerves around the heel, continued plantar fasciitis, heel or foot pain, infection, flattening of the arch, problems relating to the anesthetic.
While it's typical to experience pain in just one foot, massage and stretch both feet. Do it first thing in the morning, and three times during the day. Achilles Tendon Stretch. Stand with your affected foot behind your healthy one. Point the toes of the back foot toward the heel of the front foot, and lean into a wall. Bend the front knee and keep the back knee straight, heel firmly planted on the floor. Hold for a count of 10. Plantar Fascia Stretch. Sit down, and place the affected foot across your knee. Using the hand on your affected side, pull your toes back toward your shin until you feel a stretch in your arch. Run your thumb along your foot--you should feel tension. Hold for a count of 10.
