Overview
Plantar fasciitis is characterized by stiffness and inflammation of the main fascia (fibrous connective [ligament-like] tissue) on the bottom of the foot. It is occasionally associated with a bone spur on the heel. Occasionally there may be a partial or complete tear of the fascia of the bottom of the foot. Bone spurs themselves usually do not cause symptoms.
Causes
Each time we take a step forward, all of our body weight first rests on the heel of one foot. As our weight moves forward, the entire foot begins to bear the body’s weight, and the foot flattens and this places a great deal of pressure and strain on the plantar fascia. There is very little elasticity to the plantar fascia, so as it stretches only slightly; it pulls on its attachment to the heel. If the foot is properly aligned this pull causes no problems. However, if the foot is “pronated” (the foot rolls outward at the ankle, causing a break down of the inner side of the shoe), the arch falls excessively, and this causes an abnormal stretching of the relatively inflexible plantar fascia, which in turn pulls abnormally hard on the heel. The same pathology occurs with “supination” (the rolling inward of the foot, causing a break down of the outer side of the shoe). Supinated feet are relatively in flexible; usually have a high arch, and a short or tight plantar fascia. Thus as weight is transferred from the heel to the remainder of the foot, the tight plantar fascia hardly stretches at all, and pulls with great force on its attachment to the heel.
Symptoms
Plantar fasciitis generally occurs in one foot. Bilateral plantar fasciitis is unusual and tends to be the result of a systemic arthritic condition that is exceptionally rare among athletes. Males suffer from a somewhat greater incidence of plantar fasciitis than females, perhaps as a result of greater weight coupled with greater speed and ground impact, as well as less flexibility in the foot. Typically, the sufferer of plantar fasciitis experiences pain upon rising after sleep, particularly the first step out of bed. Such pain is tightly localized at the bony landmark on the anterior medial tubercle of the calcaneus. In some cases, pain may prevent the athlete from walking in a normal heel-toe gait, causing an irregular walk as means of compensation. Less common areas of pain include the forefoot, Achilles tendon, or subtalar joint. After a brief period of walking, the pain usually subsides, but returns again either with vigorous activity or prolonged standing or walking. On the field, an altered gait or abnormal stride pattern, along with pain during running or jumping activities are tell-tale signs of plantar fasciitis and should be given prompt attention. Further indications of the injury include poor dorsiflexion (lifting the forefoot off the ground) due to a shortened gastroc complex, (muscles of the calf). Crouching in a full squat position with the sole of the foot flat on the ground can be used as a test, as pain will preclude it for the athlete suffering from plantar fasciitis, causing an elevation of the heel due to tension in the gastroc complex.
Diagnosis
To arrive at a diagnosis, the foot and ankle surgeon will obtain your medical history and examine your foot. Throughout this process the surgeon rules out all the possible causes for your heel pain other than plantar fasciitis. In addition, diagnostic imaging studies such as x-rays or other imaging modalities may be used to distinguish the different types of heel pain. Sometimes heel spurs are found in patients with plantar fasciitis, but these are rarely a source of pain. When they are present, the condition may be diagnosed as plantar fasciitis/heel spur syndrome.
Non Surgical Treatment
In many instances, plantar fasciitis can be treated with home care. Changing your physical activities, resting the foot, and applying ice to the area are common remedies. Taking over the counter medications such as ibuprofen or acetaminophen can help reduce pain and inflammation that may have developed. An orthotic device placed in your shoes can also significantly help to reduce pain. In addition, orthotics can also help promote healing to reverse plantar fasciitis. If pain from plantar fasciitis continues despite conservative treatments, you may need to visit a doctor or podiatrist. It’s important to seek medical advice before heel pain and damage becomes worse. If the condition is allowed to worsen, more serious or invasive forms of treatment may be required to stop pain. A visit to a doctor may reveal other conditions affecting the foot as well, such as Achilles tendonitis, heel spurs, or other heel pain conditions. An x-ray may also be taken, which can reveal the presence of a heel spur. In rare cases surgery may be required to release tension on the plantar fascia, or to remove a portion of a heel spur. But again, most heel pain conditions can be resolved using conservative treatment.
Surgical Treatment
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. The most common complications of release surgery include incomplete relief of pain and nerve damage.
Prevention
Warm up properly. This means not only stretching prior to a given athletic event, but a gradual rather than sudden increase in volume and intensity over the course of the training season. A frequent cause of plantar fasciitis is a sudden increase of activity without suitable preparation. Avoid activities that cause pain. Running on steep terrain, excessively hard or soft ground, etc can cause unnatural biomechanical strain to the foot, resulting in pain. This is generally a sign of stress leading to injury and should be curtailed or discontinued. Shoes, arch support. Athletic demands placed on the feet, particularly during running events, are extreme. Injury results when supportive structures in the foot have been taxed beyond their recovery capacity. Full support of the feet in well-fitting footwear reduces the likelihood of injury. Rest and rehabilitation. Probably the most important curative therapy for cases of plantar fasciitis is thorough rest. The injured athlete must be prepared to wait out the necessary healing phase, avoiding temptation to return prematurely to athletic activity. Strengthening exercises. Below are two simple strength exercises to help condition the muscles, tendons and joints around the foot and ankle. Plantar Rolling, Place a small tin can or tennis ball under the arch of the affected foot. Slowly move the foot back and forth allowing the tin can or tennis ball to roll around under the arch. This activity will help to stretch, strengthen and massage the affected area. Toe Walking, Stand upright in bare feet and rise up onto the toes and front of the foot. Balance in this position and walk forward in slow, small steps. Maintain an upright, balanced posture, staying as high as possible with each step. Complete three sets of the exercise, with a short break in between sets, for a total of 20 meters.
