Plantar fasciitis is the most common cause of heel pain in runners, eventually affecting 10 percent of the running community. While running, the plantar fascia works with the Achilles tendon to store and return energy. Because of its powerful attachment to the base of the toe, the plantar fascia stabilizes the inner forefoot as forces peak during pushoff. Unlike bone spurs and stress fractures of the heel, plantar fasciitis tends to produce pain during the pushoff phase while running, not during initial contact. A simple way to tell if you have plantar fasciitis versus a heel spur/stress fracture is to walk on your toes: heel spurs and heel stress fractures feel better while you walk on your toes, while plantar fasciitis typically produces more discomfort when you shift your weight onto your toes.
Identified risk factors for plantar fasciitis include excessive running, standing on hard surfaces for prolonged periods of time, high arches of the feet, the presence of a leg length inequality, and flat feet. The tendency of flat feet to excessively roll inward during walking or running makes them more susceptible to plantar fasciitis. Obesity is seen in 70% of individuals who present with plantar fasciitis and is an independent risk factor. Studies have suggested a strong association exists between an increased body mass index and the development of plantar fasciitis. Achilles tendon tightness and inappropriate footwear have also been identified as significant risk factors.
Most patients with plantar fasciitis describe a sharp or stabbing pain on the bottom of the heel that is most severe when they first get up in the morning or after a period of resting. Some may feel like the heel is bruised while others may describe tightness or even a pulling sensation on the heel or arch.
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
Rest until the pain resolves and you are feeling better. For most people with plantar fasciitis it is very difficult to rest as daily routine demands using their feet during the day for work or other activities. By using the painful foot you keep on hurting the plantar fascia, harming the foot and increasing inflammation. Rest as much as you can, reduce unnecessary activities and additional stress on the fascia. Cold therapy like applying ice to the bottom of your foot helps reduce pain and inflammation. Cold therapy can be used all the time until symptoms have resolved. Some patients prefer to roll their foot over an iced cold drink can or bottle taken out of the freezer. Physical therapy Exercises are good plantar fasciitis treatment. Stretching and other physical therapy measures may be used to provide relief. Stretching the plantar fascia is reported in scientific studies to be a very effective treatment technique. Gait analysis will determine if you overpronate or oversupinate. An expert may perform a test of the way you stand and walk to see if you step in a way that puts more stress on the plantar fascia. You can try to change the way you walk and stand according to the experts recommendation as part of your treatment. Exercise the foot muscles to make the muscles stronger. One good exercise is grabbing and lifting up a towel or marbles using your toes. You can do the same exercise without a towel as though you are grasping something with the toes of each foot. Another good exercise is walking as tall as you can on your toes and on the balls of your feet. Stretching the plantar fascia and the calf muscles several times a day is an important part of the treatment and prevention. There are many stretching exercises for the plantar fascia and the calf muscles that you can find. Long term treatment should not focus in reduction of pain and inflammation alone. This is a passive short term relief treatment. Stretching exercises results are longer and more flexible foot movement which can prevent another fascia injury. Plantar fasciitis taping technique can assist the foot getting rest and help it from getting injured again. Athletic tape is applied in strips on the skin on the bottom of the foot supporting the plantar fascia. The tape restricts the movement of the foot so the fascia can not be injured again. Taping supports the foot by putting the tired foot muscles and tendons in a physiologically more relaxed position. A night splint is worn during sleep. It holds the calf muscles and plantar fascia in a stretched position. Night splint treatment lets the fascia heal in a stretched position so it will not get bruised again when waking up and stretching it again while walking. Orthotics or inserts that your doctor may prescribe or custom made arch supports (orthotics) plantar fascia orthotic. help to distribute the pressure on your feet more evenly. Arch Support gives a little raise to the arch assisting the plantar fascia. There are also over-the-counter inserts that are used for arch support and heel cushioning. Heel cups and cradles provide extra comfort and cushion the heel. They reduce shock placed on the foot during everyday activities like Shock absorbers. Anti-inflammatory or Pain medication that a clinician may recommend can be a plantar fasciitis treatment. Non-steroidal anti-inflammatory drugs such as ibuprofen can reduce swelling and relieve pain. However, these medications may have many side effects and it is important to consider the potential risks and benefits. These medications may relieve the pain and inflammation but will not cure the fascia. Lose weight as much as you can. Extra weight puts more stress on your plantar fascia. Platelet Rich Plasma or PRP therapy, is a procedure which involves an injection of special plasma, made out of the patients own blood, to the injured area. Platelets are special blood components that have a major role in the body ability to heal itself. Blood is taken from the patient and separated into its components. The platelet rich part of the blood is than taken and injected into the injured area – in our case to the bottom of the foot. The special plasma helps the foot recovery process. The procedure is actually maximizing the body’s natural healing response of the treated area. Extracorporeal shock wave therapy is a procedure which sound waves are targeted at the area of heel pain to encourage healing. It is mostly used for chronic plantar fasciitis which does not respond to conservative treatments. This procedure has many possible side effects like bruising, swelling, pain or numbness and has not proved to be consistently effective. Corticosteroid injection (or cortisone shots) into the painful area may provide relief in severe cases. This kind of medication is very efficient in inflammation reduction. Corticosteroid injections usually provide short-term relief from plantar fasciitis pain. Symptom relief from the corticosteroid injection lasts for 3 to 6 weeks, but the effect often deteriorates and symptoms return. Botox Injections (botulinum toxin) are used to relieve the pain of plantar fasciitis, assist foot function recovery and the ability to walk better. Although the use of Botox injections as heel pain treatment is relatively new, there are a number of medical studies that show significant good results.
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.
Being overweight can place excess pressure and strain on your feet, particularly on your heels. Losing weight, and maintaining a healthy weight by combining regular exercise with a healthy, balanced diet, can be beneficial for your feet. Wearing appropriate footwear is also important. Ideally, you should wear shoes with a low to moderate heel that supports and cushions your arches and heels. Avoid wearing shoes with no heels.
