What Is Plantar
Fasciitis?
Plantar fasciitis is an inflammation of the band of tissue
(the plantar fascia) that extends from the heel to the toes.
In this condition, the fascia first becomes irritated and
then inflamed — resulting in heel pain. The symptoms
of plantar fasciitis are:
• Pain on the bottom of the heel
• Pain that is usually worse upon arising
• Pain that increases over a period
of months
People with plantar fasciitis often describe the pain
as worse when they get up in the morning or after they’ve
been sitting for long periods of time. After a few minutes
of walking the pain decreases, because walking stretches
the fascia. For some people the pain subsides but returns
after spending long periods of time on their feet.
Causes of Plantar Fasciitis
The most common cause of plantar fasciitis relates to faulty
structure of the foot. For example, people who have problems
with their arches— either overly flat feet or high-arched
feet—are more prone to developing plantar fasciitis.
Wearing non-supportive footwear on hard, flat surfaces puts
abnormal strain on the plantar fascia and can also lead to
plantar fasciitis. This is particularly evident when a person’s
job requires long hours on their feet. Obesity also contributes
to plantar fasciitis.
Diagnosis
To arrive at a diagnosis, the podiatric 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, a bone scan, or
magnetic resonance imaging (MRI) 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.
Treatment Options
Treatment of plantar fasciitis begins with first-line strategies,
which you can begin at home:
• Stretching exercises. Exercises that stretch out the calf
muscles help ease pain and assist with recovery.
• Avoid going barefoot. When you walk without shoes, you
put undue strain and stress on your plantar fascia.
• Ice. Putting an ice pack on your heel for 10 minutes
several times a day helps reduce inflammation.
• Limit activities. Cut down on extended physical activities
to give your heel a rest.
• Shoe modifications. Wearing supportive shoes that have
good arch support and a slightly raised heel reduces stress on
the plantar fascia. Your shoes should provide a comfortable environment
for the foot.
• Medications. Nonsteroidal anti-inflammatory
drugs (NSAIDs), such as ibuprofen, may help reduce pain and inflammation.
• Lose weight. Extra pounds put extra stress on your plantar
fascia.
If you still have pain after several weeks, see your podiatric
surgeon, who may add one or more of these approaches:
• Padding and strapping. Placing pads in the shoe softens
the impact of walking. Strapping helps support the foot and reduce
strain on the fascia.
• Orthotic devices. Custom orthotic devices that fit into
your shoe help correct the underlying structural abnormalities
causing the plantar fasciitis.
• Injection therapy. In some cases, corticosteroid injections
are used to help reduce the inflammation and relieve pain.
• Removable walking cast. A removable walking cast
may be used to keep your foot immobile for a few weeks to allow
it to rest and heal.
• Night splint. Wearing a night splint allows you to maintain
an extended stretch of the plantar fascia while sleeping. This
may help reduce the morning pain experienced by some patients.
• Physical therapy. Exercises and other physical therapy
measures may be used to help provide relief.
Although most patients with plantar fasciitis respond to non-surgical
treatment, a small percentage of patients may require surgery.
If, after several months of non-surgical treatment, you continue
to have heel pain, surgery will be considered. Your podiatric
foot and ankle surgeon will discuss the surgical options with
you and determine which approach would be most beneficial for
you.
Long-term Care
No matter what kind of treatment you undergo for plantar fasciitis,
the underlying causes that led to this condition may remain.
Therefore, you will need to continue with preventive measures.
If you are overweight, it is important to reach and maintain
an ideal weight. For all patients, wearing supportive shoes
and using custom orthotic devices are the mainstay of long-term
treatment for plantar fasciitis. |
