Heel Spurs
Definition
The heel bone is the largest bone in the foot and
absorbs the most amount of shock and pressure. A heel spur develops
as an abnormal growth of the heel bone. Calcium deposits form
when the plantar fascia pulls away from the heel area, causing
a bony protrusion, or heel spur to develop. The plantar fascia
is a broad band of fibrous tissue located along the bottom surface
of the foot that runs from the heel to the forefoot. Heel spurs
can cause extreme pain in the rearfoot, especially while standing
or walking.
Cause
Heel spurs develop as an abnormal growth in the heel bone due
to calcium deposits that form when the plantar fascia pulls away
from the heel. This stretching of the plantar fascia is usually
the result of over-pronation (flat feet), but people with unusually
high arches (pes cavus) can also develop heel spurs. Women have
a significantly higher incidence of heel spurs due to the types
of footwear often worn on a regular basis.
Treatment and Prevention
The key for the proper treatment of heel spurs is determining
what is causing the excessive stretching of the plantar fascia.
When the cause is over-pronation (flat feet), an orthotic with
rearfoot posting and longitudinal arch support is an effective
device to reduce the over-pronation, and allow the condition
to heal.
Other common treatments include stretching exercises, losing
weight, wearing shoes that have a cushioned heel that absorbs
shock, and elevating the heel with the use of a heel cradle,
heel cup, or orthotic. Heel cradles and heel cups provide extra
comfort and cushion to the heel, and reduce the amount of shock
and shear forces experienced from everyday activities.
If the problem persists, consult your foot doctor.
