Plantar fasciitis is that pain in the bottom of your foot usually in the heel. That pain hurts especially with the first few steps in the morning as you get out of bed. This strange name comes from:
"Plantar" means something that belongs to the foot, "fascia" means a band or ligament or a connective tissue, and "itis" means inflammation. You can see in the picture the plantar fascia band as it
runs along the foot. This band connects your heel bone to the toes.
The cause of plantar fasciitis is poorly understood and is thought to likely have several contributing factors. The plantar fascia is a thick fibrous band of connective tissue that originates from
the medial tubercle and anterior aspect of the heel bone. From there, the fascia extends along the sole of the foot before inserting at the base of the toes, and supports the arch of the foot.
Originally, plantar fasciitis was believed to be an inflammatory condition of the plantar fascia. However, within the last decade, studies have observed microscopic anatomical changes indicating that
plantar fasciitis is actually due to a non-inflammatory structural breakdown of the plantar fascia rather than an inflammatory process. Due to this shift in thought about the underlying mechanisms in
plantar fasciitis, many in the academic community have stated the condition should be renamed plantar fasciosis. The structural breakdown of the plantar fascia is believed to be the result of
repetitive microtrauma (small tears). Microscopic examination of the plantar fascia often shows myxomatous degeneration, connective tissue calcium deposits, and disorganized collagen fibers.
Disruptions in the plantar fasciaâs normal mechanical movement during standing and walking (known as the Windlass mechanism) are thought to contribute to the development of plantar fasciitis by
placing excess strain on the calcaneal tuberosity.
Most people with plantar fasciitis have pain when they take their first steps after they get out of bed or sit for a long time. You may have less stiffness and pain after you take a few steps. But
your foot may hurt more as the day goes on. It may hurt the most when you climb stairs or after you stand for a long time. If you have foot pain at night, you may have a different problem, such as
arthritis , or a nerve problem such as tarsal tunnel syndrome.
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
The good news is that plantar fasciitis is reversible and very successfully treated. About 90 percent of people with plantar fasciitis improve significantly within two months of initial treatment. If
your plantar fasciitis continues after a few months of conservative treatment, your doctor may inject your heel with steroidal anti-inflammatory medications (corticosteroid). Cortisone injections
have been shown to have short-term benefits but they actually retard your progress in the medium to long-term, which usually means that you will suffer recurrent bouts for longer. Due to poor foot
biomechanics being the primary cause of your plantar fasciitis it is vital to thoroughly assess and correct your foot and leg biomechanics to prevent future plantar fasciitis episodes or the
development of a heel spur. Your physiotherapist is an expert in foot assessment and its dynamic biomechanical correction. They may recommend that you seek the advice of a podiatrist, who is an
expert in the prescription on passive foot devices such as orthotics.
When more-conservative measures aren't working, your doctor might recommend steroid shots. Injecting a type of steroid medication into the tender area can provide temporary pain relief. Multiple
injections aren't recommended because they can weaken your plantar fascia and possibly cause it to rupture, as well as shrink the fat pad covering your heel bone. Extracorporeal shock wave therapy.
In this procedure, sound waves are directed at the area of heel pain to stimulate healing. It's usually used for chronic plantar fasciitis that hasn't responded to more-conservative treatments. This
procedure may cause bruises, swelling, pain, numbness or tingling and has not been shown to be consistently effective. Surgery. Few people need surgery to detach the plantar fascia from the heel
bone. It's generally an option only when the pain is severe and all else fails. Side effects include a weakening of the arch in your foot.
An important part of prevention is to perform a gait analysis to determine any biomechanical problems with the foot which may be causing the injury. This can be corrected with orthotic inserts into
the shoes. If symptoms do not resolve then surgery is an option, however this is more common for patients with a rigid high arch where the plantar fascia has shortened.
