Plantar fasciitis is the most common cause of heel pain. Pain from plantar fasciitis is often most noticeable during the first few steps after getting out of bed in the morning. The plantar fascia is a thick band of tissue in the sole of the foot. Microtearing at the origin of the plantar fascia on the heel bone (calcaneus) can occur with repetitive loading. This microtearing leads to an inflammatory response (healing response) which produces the pain. Risk factors for plantar fasciitis include excessive standing, increased body weight, increasing age, a change in activity level, and a stiff calf muscle. Plantar fasciitis can be managed non-operatively in the vast majority of patients. The main components of an effective non-operative treatment program are: calf stretching with the knee straight, plantar fascia stretching, activity modification (to avoid precipitating activities), and comfort shoe wear.
The cause of plantar fasciitis is often unclear and may be multifactorial. Because of the high incidence in runners, it is best postulated to be caused by repetitive microtrauma. Possible risk factors include obesity, occupations requiring prolonged standing and weight-bearing, and heel spurs. Other risk factors may be broadly classified as either extrinsic (training errors and equipment) or intrinsic (functional, structural, or degenerative). Training errors are among the major causes of plantar fasciitis. Athletes usually have a history of an increase in distance, intensity, or duration of activity. The addition of speed workouts, plyometrics, and hill workouts are particularly high-risk behaviors for the development of plantar fasciitis. Running indoors on poorly cushioned surfaces is also a risk factor. Appropriate equipment is important. Athletes and others who spend prolonged time on their feet should wear an appropriate shoe type for their foot type and activity. Athletic shoes rapidly lose cushioning properties. Athletes who use shoe-sole repair materials are especially at risk if they do not change shoes often. Athletes who train in lightweight and minimally cushioned shoes (instead of heavier training flats) are also at higher risk of developing plantar fasciitis.
If you have Plantar Fasciitis, you will most likely feel a sharp pain under the ball of you heel and it will often give pain when standing after a period of rest. For example when you get out of bed in the mornings or after being sat down. Some patients describe this feeling as a stone bruise sensation, or a pebble in the shoe and at times the pain can be excruciating. Patients with Plantar Fasciitis can experience pain free periods whereby the think they are on the mend, only for the heel pain to come back aggressively when they appear to have done nothing wrong. If your plantar fasciitis came on very suddenly and the pain is relentless, then you may have Plantar Fascial Tears. We will be able to differentiate between these 2 conditions, sometimes with ultra sound imaging. The treatment for each of these conditions will need to be very different.
During the physical exam, your doctor checks for points of tenderness in your foot. The location of your pain can help determine its cause. Usually no tests are necessary. The diagnosis is made based on the history and physical examination. Occasionally your doctor may suggest an X-ray or magnetic resonance imaging (MRI) to make sure your pain isn’t being caused by another problem, such as a stress fracture or a pinched nerve. Sometimes an X-ray shows a spur of bone projecting forward 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.
Non Surgical Treatment
Over-the-counter arch supports may be useful in patients with acute plantar fasciitis and mild pes planus. The support provided by over-the-counter arch supports is highly variable and depends on the material used to make the support. In general, patients should try to find the most dense material that is soft enough to be comfortable to walk on. Over-the-counter arch supports are especially useful in the treatment of adolescents whose rapid foot growth may require a new pair of arch supports once or more per season. Custom orthotics are usually made by taking a plaster cast or an impression of the individual’s foot and then constructing an insert specifically designed to control biomechanical risk factors such as pes planus, valgus heel alignment and discrepancies in leg length. For patients with plantar fasciitis, the most common prescription is for semi-rigid, three-quarters to full-length orthotics with longitudinal arch support. Two important characteristics for successful treatment of plantar fasciitis with orthotics are the need to control over-pronation and metatarsal head motion, especially of the first metatarsal head. In one study, orthotics were cited by 27 percent of patients as the best treatment. The main disadvantage of orthotics is the cost, which may range from $75 to $300 or more and which is frequently not covered by health insurance.
In very rare cases plantar fascia surgery is suggested, as a last resort. In this case the surgeon makes an incision into the ligament, partially cutting the plantar fascia to release it. If a heel spur is present, the surgeon will remove it. Plantar Fasciitis surgery should always be considered the last resort when all the conventional treatment methods have failed to succeed. Endoscopic plantar fasciotomy (EPF) is a form of surgery whereby two incisions are made around the heel and the ligament is being detached from the heel bone allowing the new ligament to develop in the same place. In some cases the surgeon may decide to remove the heel spur itself, if present. Just like any type of surgery, Plantar Fascia surgery comes with certain risks and side effects. For example, the arch of the foot may drop and become weak. Wearing an arch support after surgery is therefore recommended. Heel spur surgeries may also do some damage to veins and arteries of your foot that allow blood supply in the area. This will increase the time of recovery.
