Heel Pain and Plantar Fasciitis
Heel pain is one of the most common conditions podiatrists treat. It
accounts for approximately 15-20% of The North Shore Podiatry Group’s practice.
Most patients with heel pain find that it is most painful with the first few
steps in the morning and after prolonged sitting. The condition can occur in
anyone, but is most common in athletic or overweight people. Feet that flatten
excessively are also more likely to develop it.
A strong ligament called the plantar fascia (Figure 1)
extends from the heel bone to the toes. When the foot flattens, the plantar
fascia becomes taut. It stretches, and begins to pull away from the heel. This
causes pain. Over time, the pulling stimulates the heel bone to produce a heel
spur (Figure 2). The heel spur itself is usually not the cause of the pain.
Treatment
Most of our patients gain relief from conservative
treatments which include:
- Icing and stretching exercises performed daily.
- Taping the foot in a manner that relaxes the plantar
fascia by controlling pronation (flattening).
- Orthotics (custom supports) to relax the plantar fascia by
controlling pronation.
- Modification of exercise routines.
- Changing to shoes with good support and heel cushioning.
Other conservative treatments include: cortisone injections, oral
anti-inflammatory medications, physical therapy, and night splints.
Extracorporeal Shock Wave Therapy (ESWT)
This revolutionary new treatment was approved by the FDA in
July, 2002 for treatment of chronic heel pain that is unresponsive to
conservative therapy. ESWT is a non-invasive, non-surgical procedure that
administers high intensity shock waves to the precise area of inflammation,
which is the point where the plantar fascia attaches to the heel bone. The
shock waves increase blood flow to the area and stimulate a healing response.
ESWT uses the same technology and instrumentation as lithotrypsy has for many
years to break up kidney stones.
ESWT is performed by the doctors of the North Shore Podiatry
Group under local anesthesia. The procedure takes about 20 minutes. The patient
can immediately return to a supportive shoe and may drive home from the
procedure. Normal walking is permitted, but athletic activity should be
eliminated for about four weeks. Complete relief of heel pain has been obtained
by approximately 90% of the patients who have been treated with ESWT by the
North Shore Podiatry Group.
Surgery
ESWT has practically eliminated the surgical treatment of plantar
Fasciitis and heel spurs in our practice. When it is necessary, however, the
doctors of the North Shore Podiatry Group perform Endoscopic Plantar Fasciotomy.
The procedure is performed through two incisions, each the diameter of a
drinking straw. A miniature television camera (the endoscope) is placed into
one incision. In the other, a small blade is inserted. The surgeon sees the
plantar fascia on a television screen. It is easily and precisely cut. The heel
spur is not touched. If you are a candidate for Endoscopic Plantar Fasciotomy,
your doctor will give you a detailed explanation of the surgery and its
post-operative course.
