The plantar fascia is a thickened fibrous aponeurosis that originates from the medial tubercle of the calcaneus, runs forward to insert into the deep, short transverse ligaments of the metatarsal
heads, dividing into 5 digital bands at the metatarsophalangeal joints and continuing forward to form the fibrous flexor sheathes on the plantar aspect of the toes. Small plantar nerves are invested
in and around the plantar fascia, acting to register and mediate pain.
Plantar fasciitis symptoms are usually exacerbated via "traction" (or stretching) forces on the plantar fascia. In simple terms, you plantar fascia is repeatedly overstretched. The most common reason
for the overstretching are an elongated arch due to either poor foot biomechanics (eg overpronation) or weakness of your foot arch muscles. Compression type plantar fascia injuries have a traumatic
history. Landing on a sharp object that bruises your plantar fascia is your most likely truma. The location of plantar fasciitis pain will be further under your arch than under your heel, which is
more likely to be a fat pad contusion if a single trauma caused your pain. The compression type plantar fasciitis can confused with a fat pad contusion that is often described as a "stone
Symptoms of plantar fasciitis include pain in the heel of the foot. Some people complain of a sharp stabbing pain especially with walking. Others describe the pain as a dull ache after prolonged
standing. The pain of plantar fasciitis is often worst in the morning or following 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.
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.
In one exercise, you lean forward against a wall with one knee straight and heel on the ground. Your other knee is bent. Your heel cord and foot arch stretch as you lean. Hold for 10 seconds, relax
and straighten up. Repeat 20 times for each sore heel. It is important to keep the knee fully extended on the side being stretched. In another exercise, you lean forward onto a countertop, spreading
your feet apart with one foot in front of the other. Flex your knees and squat down, keeping your heels on the ground as long as possible. Your heel cords and foot arches will stretch as the heels
come up in the stretch. Hold for 10 seconds, relax and straighten up. Repeat 20 times. About 90 percent of people with plantar fasciitis improve significantly after two months of initial treatment.
You may be advised to use shoes with shock-absorbing soles or fitted with an off-the-shelf shoe insert device like a rubber heel pad. Your foot may be taped into a specific position. If your plantar
fasciitis continues after a few months of conservative treatment, your doctor may inject your heel with steroidal anti-inflammatory medication. If you still have symptoms, you may need to wear a
walking cast for two to three weeks or a positional splint when you sleep. In a few cases, surgery is needed for chronically contracted tissue.
