Plantar fasciosis is a foot condition characterized by heel pain and pain in your plantar fascia-a strong and dense connective tissue structure on the sole of your foot that supports your foot arch. This condition has historically been called plantar fasciitis because it was believed that plantar fascia inflammation was the principle underlying cause. Plantar fasciosis is a more accurate name for this condition because it involves degeneration-microtears, cell death-of your plantar fascia, not inflammation. Active men between the ages of 40 and 70 are most commonly affected by this health problem.
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.
The most common symptoms of plantar fasciitis include pain on the bottom of the foot near the heel, pain with the first few steps after getting out of bed in the morning, or after a long period of rest, such as after a long car ride. The pain subsides after a few minutes of walking. Greater pain after (not during) exercise or activity.
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 Orthotics. A soft, over-the-counter orthotic (Prefabricated orthotic) with an accommodating arch support has proven to be quite helpful in the management of plantar fascia symptoms. Studies demonstrate that it is NOT necessary to obtain a custom orthotic for the treatment of this problem. Comfort Shoes. Shoes with a stiff sole, rocker-bottom contour, and a comfortable leather upper combined with an over-the-counter orthotic or a padded heel can be very helpful in the treatment of plantar fasciitis. Anti-Inflammatory Medication (NSAIDs): A short course of over-the-counter anti-inflammatory medications may be helpful in managing plantar fasciitis symptoms providing the patient does not have any contra-indications such as a history of stomach ulcers. Activity Modification Any activity that has recently been started, such as a new running routine or a new exercise at the gym that may have increased loading through the heel area, should be stopped on a temporary basis until the symptoms have resolved. At that point, these activities can be gradually started again. Also, any activity changes (ex. sitting more) that will limit the amount of time a patient is on their feet each day may be helpful. A night splint, which keeps the ankle in a neutral position (right angle) while the patient sleeps, can be very helpful in alleviating the significant morning symptoms. A night splint may be prescribed by your physician. Alternatively, it can be ordered online or even obtained in some medical supply stores. This splint is worn nightly for 1-3 weeks until the cycle of pain is broken. Furthermore, this splinting can be reinstituted for a short period of time is symptoms recur.
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.
Calf stretch. Lean forward against a wall with one knee straight and the heel on the ground. Place the other leg in front, with the knee bent. To stretch the calf muscles and the heel cord, push your hips toward the wall in a controlled fashion. Hold the position for 10 seconds and relax. Repeat this exercise 20 times for each foot. A strong pull in the calf should be felt during the stretch. Plantar fascia stretch. This stretch is performed in the seated position. Cross your affected foot over the knee of your other leg. Grasp the toes of your painful foot and slowly pull them toward you in a controlled fashion. If it is difficult to reach your foot, wrap a towel around your big toe to help pull your toes toward you. Place your other hand along the plantar fascia. The fascia should feel like a tight band along the bottom of your foot when stretched. Hold the stretch for 10 seconds. Repeat it 20 times for each foot. This exercise is best done in the morning before standing or walking.
