What Exactly Brings About Plantar Fasciitis

Overview

Plantar fasciitis is a common, painful foot condition. Patients, and sometimes doctors often confuse the terms plantar fasciitis and heel spurs. Plantar fasciitis refers to the syndrome of inflammation of the band of tissue that runs from the heel along the arch of the foot; a heel spur is a hook of bone that can form on the heel bone (calcaneus). About 70% of patients with plantar fasciitis have been noted to have a heel spur that can be seen on x-ray. Plantar fasciitis is most often seen in middle-aged men and women, but can be found in all age groups. The condition is diagnosed with the classic symptoms of pain well focused deep in the heel area of the bottom of the foot. Often the pain from plantar fasciitis is most severe when you first stand on your feet in the morning. Pain often subsides quite quickly, but then returns after prolonged standing or walking. Plantar fasciitis is sometimes, but not always, associated with a rapid gain of weight. It is also sometimes seen in recreational athletes, especially runners. In these athletes, it is thought that the repetitive nature of the sports causes the damage to the fibrous tissue that forms the arch of the foot.




Causes

Far and away the most common cause of plantar fasciitis in an athlete is faulty biomechanics of the foot or leg. Faulty biomechanics causes the foot to sustain increased or prolonged stresses over and above those of routine ground contacts. Throughout the phase of ground contact, the foot assumes several mechanical positions to dissipate shock while at the same time placing the foot in the best position to deliver ground forces. With heel landing the foot is supinated (ankle rolled out). At mid-stance the foot is pronated (ankle rolled in). The foot is supinated again with toe-off. The supination of the foot at heel strike and toe-off makes the foot a rigid lever. At heel strike the shock of ground contact is transferred to the powerful quads. During toe-off forward motion is created by contraction of the gastroc complex plantar flexing the rigid lever of the foot pushing the body forward.




Symptoms

A very common complaint of plantar fasciitis is pain in the bottom of the heel. Plantar fasciitis is usually worse in the morning and may improve throughout the day. By the end of the day the pain may be replaced by a dull aching that improves with rest. Most people suffering from plantar fasciitis also complain of increased heel pain after walking for a long period of time.




Diagnosis

Your doctor can usually diagnose plantar fasciitis just by talking to you and examining your feet. Rarely, tests are needed if the diagnosis is uncertain or to rule out other possible causes of heel pain. These can include X-rays of the heel or an ultrasound scan of the fascia. An ultrasound scan usually shows thickening and swelling of the fascia in plantar fasciitis.




Non Surgical Treatment

Most doctors recommend an initial six- to eight-week program of conservative treatment, including Rest, balanced with stretching exercises to lengthen the heel cord and plantar fascia. Ice massage to the bottom of the foot after activities that trigger heel pain. Avoidance of walking barefoot or wearing slippers or sandals that provide little arch support. A temporary switch to swimming and/or bicycling instead of sports that involve running and jumping. Shoes with soft heels and insoles. Taping the bottom of the injured foot. Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen (Advil, Motrin and other brand names), or acetaminophen (Tylenol) for pain. Physical therapy using ultrasound, electrical stimulation with corticosteroids or massage techniques. If this conservative treatment does not help, your doctor may recommend that you wear a night splint for six to eight weeks. While you sleep, the night splint will keep your foot in a neutral or slightly flexed (bent) position to help maintain the normal stretch of the plantar fascia and heel cord. If the night splint doesn't work, your doctor may inject corticosteroid medication into the painful area or place your foot in a short leg cast for one to three months. Shock wave therapy, in which focused sound energy is applied to the sore heel, may be recommended for plantar fasciitis. The shock waves are intended to irritate or injure the plantar fascia to promote healing. The overall benefit of this approach is uncertain. Other therapies that have been tried include radiation therapy and botulinum toxin injections. But their effectiveness is unclear. If all else fails, your doctor may suggest surgery. But this is rare, and surgery is not always successful.






Surgical Treatment

The most common surgical procedure for plantar fasciitis is plantar fascia release. It involves surgical removal of a part from the plantar fascia ligament which will relieve the inflammation and reduce the tension. Plantar fascia release is either an open surgery or endoscopic surgery (insertion of special surgical instruments through small incisions). While both methods are performed under local anesthesia the open procedure may take more time to recover. Other surgical procedures can be used as well but they are rarely an option. Complications of plantar fasciitis surgery are rare but they are not impossible. All types of plantar fasciitis surgery pose a risk of infection, nerve damage, and anesthesia related complications including systemic toxicity, and persistence or worsening of heel pain.




Stretching Exercises

The following exercises are commonly prescribed to patients with this condition. You should discuss the suitability of these exercises with your physiotherapist prior to beginning them. Generally, they should be performed 2 - 3 times daily and only provided they do not cause or increase symptoms. Your physiotherapist can advise when it is appropriate to begin the initial exercises and eventually progress to the intermediate and advanced exercises. As a general rule, addition of exercises or progression to more advanced exercises should take place provided there is no increase in symptoms. Calf Stretch with Towel. Begin this stretch in long sitting with your leg to be stretched in front of you. Your knee and back should be straight and a towel or rigid band placed around your foot as demonstrated. Using your foot, ankle and the towel, bring your toes towards your head until you feel a stretch in the back of your calf, Achilles tendon, plantar fascia or leg. Hold for 5 seconds and repeat 10 times at a mild to moderate stretch provided the exercise is pain free. Resistance Band Calf Strengthening. Begin this exercise with a resistance band around your foot as demonstrated and your foot and ankle held up towards your head. Slowly move your foot and ankle down against the resistance band as far as possible and comfortable without pain, tightening your calf muscle. Very slowly return back to the starting position. Repeat 10 - 20 times provided the exercise is pain free.
